RESUMEN
Introducción. Las complicaciones posteriores a la reparación endovascular de aneurisma (EVAR) pueden resolverse con técnicas endovasculares. Sin embargo, cuando está indicada, la explantación de una endoprótesis es un procedimiento complejo, que se asocia a lesiones vasculares o viscerales, con alta morbimortalidad, en pacientes con edad avanzada y múltiples comorbilidades, y por lo tanto, alto riesgo quirúrgico. No existen dispositivos producidos por la industria para explantar las endoprótesis aórticas, por lo que el objetivo de este trabajo fue desarrollar un dispositivo para la explantación de endoprótesis aórticas. Métodos. Se llevó a cabo un estudio experimental, en fase preclínica, para desarrollar un dispositivo para la explantación de endoprótesis aórticas, con pruebas en modelos 3D y en un modelo animal porcino cadavérico. Resultados. Es factible desarrollar un modelo experimental de un nuevo dispositivo para explantar endoprótesis aórticas, denominado explantador de Cabrera, y comprobar su funcionamiento en un modelo animal cadavérico. El uso del explantador de Cabrera limitó el daño de la pared aórtica por parte de la endoprótesis en un 100 % al momento de su explantación en un modelo experimental ex vivo. Conclusión. Usando una jeringa septo, el explantador de Cabrera es superior a la técnica estándar de explantación de una endoprótesis al limitar la lesión de la pared aórtica, al colapsar y liberar los ganchos de fijación suprarrenal de forma controlada y segura al interior de la luz aórtica y, posteriormente, extraerla de forma rápida y efectiva, conservando la mayor cantidad de aorta sana para la posterior reconstrucción aorto-ilíaca.
Introduction. Complications after endovascular aneurysm repair (EVAR) can be resolved with endovascular techniques; however, when indicated, stent explantation is a complex procedure, which is associated with vascular or visceral injuries, with high morbidity and mortality in patients, with advanced age and multiple comorbidities, and therefore high surgical risk. There are no devices produced by the industry to explant aortic endoprostheses, so the objective of this work was to develop a device for the explantation of aortic endoprostheses. Methods. An experimental study was carried out, in the preclinical phase, to develop a device for the explantation of aortic endoprostheses, with tests in 3D models and in a cadaveric porcine animal model. Results. It is feasible to develop an experimental model of a new device for explanting aortic endoprostheses, called Cabrera explanter, and verify its operation in a cadaveric animal model. The use of the Cabrera explanter limited damage to the aortic wall by the endoprosthesis by 100% at the time of explantation in an ex vivo experimental model. Conclusions. Using a septum syringe, the Cabrera explanter is superior to the standard stent explantation technique by limiting injury to the aortic wall, collapsing and releasing the adrenal fixation hooks in a controlled and safe manner into the aortic lumen, and subsequently, extract it quickly and effectively, preserving the greatest amount of healthy aorta for the subsequent aorto-iliac reconstruction.

BACKGROUND: In Mexico, there is a paucity of evidence on mortality and hospitalization patterns associated with aortic aneurysms and dissections. OBJECTIVE: To analyze national databases and describe the epidemiological characteristics of different aortic pathologies. MATERIAL AND METHODS: Retrospective, cross-sectional, observational study, in which mortality and hospitalization attributed to aortic aneurysms and dissections were analyzed. Statistical analysis was performed on Stata 16. RESULTS: A total of 6,049 deaths were documented in the general population, which included 2,367 hospitalizations and 476 (20.1%) in-hospital deaths. In addition, a statistically significant age difference was found between mean age at death in the general population (69.5 years) and the in-hospital death group (64.1 years, p < 0.001). As for hospitalizations secondary to ruptured abdominal aortic aneurysms, 149 cases were identified, with a mean age of 65.6 years, out of whom 53 (35.5%) were under 65 years of age, with a mean age of 47.8 years. CONCLUSIONS: Epidemiological reports of aortic pathology in Mexico are scarce; therefore, implementation of screening and detection programs for aortic pathologies is necessary in order to address the disparities identified in this analysis.

RESUMEN
Introducción. El aneurisma de la aorta abdominal (AAA) es la dilatación de la aorta abdominal mayor de 1,5 veces el diámetro esperado. Su prevalencia es variable, con tasas reportadas de hasta el 12,5 %. Se considera como causa de muerte de más de 10.000 personas al año en los Estados Unidos. El objetivo de esta revisión de la literatura fue describir los factores de riesgo y las herramientas de tamizaje de AAA. Métodos. Se realizó una búsqueda de la literatura utilizando dos ecuaciones en bases de datos electrónicas, empleando términos seleccionados de "Medical Subject Heading" (MeSH) y "Descriptores en Ciencias de la Salud" (DeCS). Se evaluó la calidad de los estudios con la herramienta STROBE (Strengthening the Reporting of Observational Studies in Epidemiology). Resultados. Se recolectaron 40 artículos y a partir de ellos se construyó el texto de revisión, identificando en estos, los factores de riesgo asociados al desarrollo de AAA, tales como sexo masculino, tabaquismo, hipertensión arterial, antecedente familiar y obesidad, entre otros. La diabetes mellitus parece actuar como factor protector. Dentro de los instrumentos de tamizaje, el ultrasonido abdominal es uno de los más usados. Conclusión. El AAA es una patología multifactorial. En la actualidad la ultrasonografía de aorta es el método de elección para el tamizaje, permitiendo la detección precoz. El tamizaje de AAA con métodos no invasivos, como el ultrasonido, es útil sobre todo en zonas con prevalencia alta de la patología y en pacientes con determinados factores de riesgo.
Introduction. Abdominal aortic aneurysm (AAA) is a dilation of the abdominal aorta greater than 1.5 times the expected diameter. Its prevalence is variable, with reported rates of up to 12.5%. It is considered the cause of death of more than 10,000 people a year in the United States. The objective of this literature review was to describe risk factors and screening tools for AAA. Methods. A literature search was conducted using two equations in electronic databases, using terms selected from "Medical Subject Heading" (MeSH) and "Descriptors in Health Sciences" (DeCS). The quality of the studies was evaluated with the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) tool. Results. Forty articles were collected and from them the review text was constructed, identifying the risk factors associated with the development of AAA, such as male sex, smoking, high blood pressure, family history and obesity, among others. Diabetes mellitus seems to act as a protective factor. Among the screening instruments, abdominal ultrasound is one of the most used. Conclusion. AAA is a multifactorial pathology. Currently, aortic ultrasonography is the method of choice for screening, allowing early detection. Screening for AAA with non-invasive methods, such as ultrasound, is useful especially in areas with a high prevalence of this pathology and in patients with certain risk factors.

Resumo O aneurisma da aorta abdominal pode representar um desafio terapêutico em várias condições anatômicas, tornando complexo o seu tratamento endovascular. O aneurisma de aorta abdominal justarrenal (AAA-JR) é definido pela ausência de uma zona proximal de fixação no segmento infrarrenal, e, dessa forma, técnicas são utilizadas para obter um colo adequado para a fixação das endopróteses sem promover a oclusão das artérias renais e dos ramos viscerais. As técnicas de stents em paralelo, fenestração em bancada, customização pela indústria e utilização de endoprótese ramificada de prateleira são utilizadas nos aneurismas abdominais com colo proximal inadequado, porém cada técnica apresenta indicação, limitação e riscos. Neste desafio terapêutico, apresenta-se um caso de tratamento endovascular de urgência de um AAA-JR com a técnica de stents em paralelo com boa evolução a médio prazo e discute-se suas opções terapêuticas.
Abstract Abdominal aortic aneurysms can constitute a therapeutic challenge in several anatomical scenarios, making endovascular treatment more complex. A juxtarenal abdominal aortic aneurysm (JR-AAA) is defined by the absence of a proximal landing zone in the infrarenal segment and, therefore, techniques must be used to obtain an adequate neck for fixing the endoprostheses without provoking occlusion of renal arteries and visceral branches. The parallel grafts technique, physician-modified stent-graft, industry customized endoprostheses, and off-the-shelf branched endoprosthesis are techniques used in abdominal aneurysms with inadequate proximal neck, but each technique has its indications, limitations, and risks. In this therapeutic challenge, we present a case of urgent endovascular treatment of a JR-AAA using a parallel grafts technique, with good medium-term results, and discuss the therapeutic options.
RESUMEN
Resumo A aorta dorsal dupla persistente é uma anomalia congênita extremamente rara, com apenas 13 casos publicados até o presente momento. Este estudo tem como objetivo apresentar a variação embriológica observada em aorta abdominal do paciente. A descrição anatômica foi realizada a partir da revisão de prontuário eletrônico e exames de imagem. Desta forma, o presente caso refere-se a um paciente idoso de 79 anos admitido em atendimento hospitalar por queixa de dor em membro inferior esquerdo ao repouso. Foi solicitada a internação do mesmo, assim como exames laboratoriais e de imagem. Obtida como um achado de imagem a partir de angiotomografia, a variação consiste na completa separação em duas porções: uma ventral e outra dorsal, de calibres diferentes, da aorta abdominal, ao nível da terceira vértebra lombar. Isso ocorre em conjunto com a origem anômala da artéria mesentérica inferior.
Abstract Persistent double dorsal aorta is an extremely rare congenital anomaly, with only 13 cases published to date. The objective of this study is to present this embryological variant as observed in the abdominal aorta of a patient. The anatomical description was written up on the basis of a review of electronic medical records and imaging exams. The patient in this case was an elderly 79-year-old man who presented at emergency with pain at rest in the left lower limb. He was admitted and laboratory tests and imaging exams were ordered. The variation was an imaging finding observed on angiotomography, consisting of complete separation of the abdominal aorta into two portions - a ventral and a dorsal, with different calibers - at the level of the third lumbar vertebra. There was also an anomalous origin of the inferior mesenteric artery.
RESUMEN
El reconocimiento de variantes en el origen de las arterias renales, representa un reto al conocimiento general de la anatomía humana. Generalmente, los riñones constan de, arterias renales originadas en la aorta abdominal, una a cada lado, sin embargo, no es raro encontrar más de una emergiendo de la parte abdominal de la aorta. Presentamos un caso en una pieza cadavérica de la Universidad Central sede Cochabamba- Bolivia, donde se evidencia dos arterias renales unilaterales derechas originadas a diferentes niveles de la arteria aorta abdominal.
The recognition of variants in the origin of the renal arteries represents a challenge to the general knowledge of human anatomy. Generally, the kidneys consist of renal arteries originating from the abdominal aorta, one on each side; however, it is not uncommon to find more than one emerging from the abdominal part of the aorta. We present a case in a cadaveric specimen from the Central University, Cochabamba-Bolivia, where two right unilateral renal arteries are evident originating at different levels of the abdominal aorta artery.
RESUMEN
Abstract Objective: The aim of the study was to compare the immediate and long-term outcomes of endovascular aneurysm repair (EVAR) between patients under and over the age of 80 with abdominal aortic aneurysm (AAA). Methods: From 2011 to 2017, we conducted a retrospective cohort study with AAA patients who received elective EVAR. Primary outcomes included hospital mortality, length of stay, acute kidney injury, and the need for re-interventions. Secondary outcomes included aneurysm-related mortality, acute myocardial infarction, stroke, acute limb ischemia, and prolonged mechanical ventilation. Results: A total of 77 (62.6%) patients under the age of 80 years old and 46 (37.4%) octogenarians were included in the study. The male gender and AAA diameter did not differ among groups (92.2% vs. 82.6%, p = 0.11 and 5.4 cm [4.9-6.2 cm] vs. 5.4 cm [5-6 cm], p = 0.53, respectively). The younger patients had a higher prevalence of tobacco use (72.7% vs. 41.7%, p = 0.01). There were no deaths during the index hospitalization. The incidence of reinterventions (5.3% vs. 15.2%, p = 0.11) and acute kidney injury (14.3% vs. 23.9%, p = 0.18) did not differ between groups, but the length of stay was longer for octogenarian patients (3 days [2-4] vs. 2 days [2-3, p = 0.04]). Endoleaks were the most common cause for re-interventions (81.8%), with a prevalence of 34% across the entire cohort. There were no differences in any of the secondary outcomes between groups. Conclusion: In octogenarian patients with AAA, EVAR represents a safe procedure both during the index hospitalization and during long-term follow-up.
Resumen Objetivo: Comparar los resultados inmediatos y a largo plazo de la reparación endovascular del aneurisma de aorta abdominal (REVA) entre pacientes menores de 80 años y octogenarios. Método: Cohorte retrospectiva que incluyó pacientes con aneurisma de aorta abdominal (AAA) sometidos a REVA electiva desde 2011 hasta 2017. Se evaluaron como punto finales primarios la mortalidad hospitalaria, la duración de la estadía hospitalaria, la incidencia de insuficiencia renal aguda y el requerimiento de reintervenciones. Los puntos finales secundarios incluyeron la mortalidad asociada al aneurisma, infarto agudo de miocardio, accidente cerebrovascular, isquemia arterial aguda de las extremidades y ventilación mecánica prolongada. Resultados: Se incluyeron 77 (62.6%) pacientes menores de 80 años y 46 (37.4%) octogenarios. La prevalencia de sexo masculino y el diámetro del AAA no difirieron entre ambos grupos (92.2% vs. 82.6%, p = 0.11 y 5.4 cm [4.9-6.2 cm] vs. 5.4 cm [5-6 cm], p = 0.53, respectivamente). Los pacientes más jóvenes presentaron una mayor prevalencia de tabaquismo (72.7% vs. 41.7%, p = 0.01). No se registraron muertes durante la hospitalización índice. La incidencia de reintervenciones (5.3% vs. 15.2%, p = 0.11) e insuficiencia renal aguda (14.3% vs. 23.9%, p = 0.18) no difirieron entre ambos grupos, pero la estadía hospitalaria fue más prolongada en pacientes octogenarios (3 días [2-4 días] vs. 2 días [2-3 días], p = 0.04). La causa más frecuente de reintervenciones fue la presencia de endofugas (81.8%), con una prevalencia del 34% en toda la cohorte. No se observaron diferencias en ninguno de los puntos finales secundarios entre ambos grupos. Conclusión: En pacientes octogenarios con AAA, la REVA presentó un buen perfil de seguridad perioperatorio y a largo plazo.
RESUMEN
OBJECTIVE: The objective of the study is to evaluate the characteristics and outcomes of patients with abdominal aortic aneurysm (AAA) and its correlation with mortality in the first 30 days after the procedure was performed. METHODS: Demographic information, clinical and radiological characteristics, as well as outcomes 30 days after the procedure was performed were assessed and compared. Continuous variables were analyzed with Student's t-test and categorical with Chi-square and Fisher's exact test. RESULTS: Duration of the procedure (p = 0.001), blood loss (p < 0.001), age > 75 years (p = 0.027), aneurysm size > 65 mm (p = 0.01), open surgery (p = 0.001), presence of pain (p = 0.005), chronic kidney disease (p = 0.03), and rupture of the aneurysm (p < 0.001) were the factors significantly associated with mortality. CONCLUSION: It is essential that patient characteristics and comorbidities are assessed, as well as factors that may affect the outcomes to predict the prognosis in patients with AAA. At present, no mortality predictive model is universally applicable and highly variable performance across different populations might need a model that adapts to the population of interest.
OBJETIVO: Evaluar las características y resultados de los pacientes con aneurisma de aorta abdominal y su correlación con la mortalidad en los primeros 30 días después de realizado el procedimiento. MÉTODOS: Se evaluó y comparó la información demográfica, las características clínicas y radiológicas, así como los resultados a los 30 días de realizado el procedimiento. Las variables continuas se analizan con la prueba de t de Student y las categóricas con Chi-cuadrado y la prueba exacta de Fisher. RESULTADOS: La duración del procedimiento (p = 0.001), pérdida de sangre (p < 0.001), edad > 75 años (p = 0.027), tamaño del aneurisma > 65 mm (p = 0.01), cirugía abierta (p = 0.001), presencia de dolor (p = 0.005), enfermedad renal crónica (p = 0.03) y rotura del aneurisma (p < 0.001) fueron los factores asociados significativamente a la mortalidad. CONCLUSIÓN: Es fundamental evaluar las características de los pacientes y las comorbilidades, así como los factores que pueden afectar los resultados para predecir el pronóstico en pacientes con aneurisma de aorta abdominal. En la actualidad, ningún modelo predictivo de mortalidad es universalmente aplicable y la alta variabilidad de resultados entre diferentes poblaciones podría necesitar un modelo que se adapte a la población de interés.

RESUMEN Introducción: la anatomía arterial es la principal limitante para el abordaje aórtico endovascular estándar. Presentamos nuestra experiencia para la reparación endovascular de aneurismas aórticos complejos. Material y métodos: estudio observacional retrospectivo en pacientes con aneurismas complejos (yuxta/pararrenales y toracoabdominales) tratados en forma consecutiva mediante: endoprótesis fenestradas (FEVAR), ramificadas (BEVAR), con EndoAnchors (ESAR), o en chimenea (ChEVAR). La decisión de la técnica fue determinada con base en la anatomía arterial. Resultados: se evaluaron los últimos 50 procedimientos (6 mujeres; edad promedio 71,3 años; diámetro 69,6mm; 3 pacientes con aneurismas complicados), de los cuales 22 recibieron FEVAR (2,8 fenestraciones / paciente), 11 BEVAR, 11 ESAR y 6 ChEVAR (1,8 chimeneas /paciente). La tasa de éxito técnico fue del 100% (ausencia de endoleak I o III con permeabilidad adecuada de los vasos viscerales). A 30 días 3 pacientes fallecieron (6%). Durante el seguimiento, 5 pacientes presentaron oclusión de la arteria renal, repermeabilizada en 4. Cuatro pacientes desarrollaron un endoleak tipo IA (3 ESAR secundarios y un ChEVAR), un paciente un endoleak IC y un cuarto uno IIIB (22%, 3 de los 11 ESAR, ninguno de los FEVAR industriales). En el análisis de supervivencia, la supervivencia global fue del 88,6% al año, y libre de reoperación del 86,5%. Conclusiones: se trata de la primera publicación en nuestro medio que muestra un enfoque global del paciente con un aneurisma de aorta complejo, de acuerdo con sus características anatómicas. Estas tecnologías ya desempeñan un papel primario en el tratamiento de estos pacientes.
ABSTRACT Background: Arterial anatomy is the main limiting factor for standard endovascular aortic (EVAR) approach. We present our experience for endovascular repair of complex aortic aneurysms. Material and Methods: This is a retrospective observational study in patients with complex aneurysms (juxta/pararenal and thoracoabdominal) treated consecutively with: fenestrated (FEVAR), branched (BEVAR), EndoAnchors (ESAR), or chimney (ChEVAR) stents. The decision of the technique was determined based on the arterial anatomy. Results: The last 50 procedures were evaluated (6 women; mean age 71.3 years; diameter 69.6 mm; and 3 patients with complicated aneurysms), among whom 22 received FEVAR (2.8 fenestrated stents/patient), 11 BEVAR, 11 ESAR and 6 ChEVAR (1.8 chimney stents/patient). Technical success rate was 100% (absence of type I or III endoleak with adequate patency of the visceral vessels). Three patients died within the first 30 days (6%). During follow-up, 5 patients presented with renal artery occlusion, treated successfully in 4 cases. Four patients developed type IA endoleak (3 secondary ESAR and one ChEVAR), one patient IC endoleak and almost a quarter of cases type IIIB endoleak (22%, 3 out of 11 patients receiving ESAR, none of the industrial FEVAR group). In survival analysis, overall survival analysis was 88.6% at one year, and 86.5% of cases were free from reoperation. Conclusions: This is the first publication in our setting that shows a global approach to the patient with complex aortic aneurysm, according to the anatomical characteristics. These technologies already play a primary role in the treatment of these patients.
RESUMEN
RESUMEN El aneurisma de aorta abdominal (AAA) sintomático no roto es una patología que involucra a aquellos pacientes con AAA intacto, pero que presentan dolor abdominal y/o lumbar atribuido al aneurisma. Esta forma de presentación clínica es po tencialmente mortal dado que su etiopatogenia comprende cambios agudos en la pared aórtica, incluyendo inflamación, lo que incrementa la probabilidad de ruptura inminente. Está claro que estos pacientes deben ser derivados a reparación del AAA. Sin embargo, el momento de la intervención es controvertido. Por lo tanto, el objetivo del presente trabajo fue revisar la información actualizada sobre el abordaje diagnóstico-terapéutico del AAA sintomático no roto.
ABSTRACT Symptomatic unruptured abdominal aortic aneurysm (AAA) refers to a group of patients with intact AAA but who present abdominal and/or lumbar pain attributed to the aneurysm. This form of clinical presentation is potentially fatal since its etiopathogenesis, involving acute changes in the aortic wall, including inflammation, increases the probability of impending rupture. It is clear that these patients should be referred to AAA repair. However, the timing of the intervention is contro versial. Therefore, the aim of the present work was to review updated information on the diagnostic-therapeutic approach of symptomatic unruptured AAA.
RESUMEN
Abstract A 100-year-old male patient was admitted with a ruptured abdominal aortic aneurysm due to type IA endoleak. Given the proximity of the ruptured site to the superior mesenteric artery (SMA) and renal arteries, a ChEVAR was indicated. Catheterization of the target visceral vessels was a challenging procedural step because of an intensely tortuous thoracic aorta. This hostile aortic anatomy also inhibited exchange for a super stiff guide-wire and selective cannulation with the diagnostic catheter was repeatedly lost when guidewire exchange was attempted. To overcome this issue, a 5 x 40 mm balloon catheter was placed 3cm into the target arteries. The balloon was then inflated below the nominal pressure limit enabling safe exchange for a super stiff guidewire and placement of three 90-cm long 7Fr guiding sheaths. The procedure was thus safely performed with deployment of an aortic extension and the bridging stents.
Resumo Um paciente de 100 anos foi diagnosticado com um aneurisma de aorta abdominal roto por um endoleak 1A. Pela proximidade do ponto de ruptura com a artéria mesentérica superior (AMS) e as artérias renais, um ChEVAR foi indicado. A cateterização das artérias-alvo foi um passo desafiador pela intensa tortuosidade da aorta torácica. Essa anatomia aórtica hostil também impediu a troca por um fio-guia extra-rígido, e a cateterização seletiva foi repetidamente perdida quando a troca de fio-guia foi tentada. Para superar essa dificuldade, um cateter balão 5mm x 40mm foi posicionado nas artérias-alvo. O balão foi, então, insuflado abaixo da pressão nominal, permitindo uma troca segura do fio-guia por um fio-guia extra-rígido e o posicionamento de três bainhas longas 7Frx 90cm. Assim, o procedimento foi executado de forma segura, com o implante de uma extensão aórtica e dos stents recobertos.
RESUMEN
Resumen Presentamos el caso de un paciente de edad avanzada, con diabetes mellitus descompensada, quien presentó un cuadro clínico de fiebre y dolor abdominal recurrente, tras lo cual fue diagnosticado con un aneurisma infeccioso de la aorta abdominal, los cuales representan solamente un 1% de todos los aneurismas. El paciente fue sometido a resección quirúrgica del aneurisma, injerto con dacrón impregnando con rifampicina y tratamiento antibiótico intravenoso. La microbiología del aneurisma confirmó infección por Salmonella. Actualmente, el paciente se encuentra asintomático y sin evidencia laboratorial de proceso inflamatorio.

Introducción. En las últimas décadas, la terapia endovascular en aneurismas aórticos abdominales ha ganado un papel representativo en los escenarios quirúrgicos, lo que nos motivó a conocer los resultados de este procedimiento en nuestra población. Métodos. Estudio analítico retrospectivo en el cual se incluyeron los primeros 50 casos de aneurismas aórticos abdominales con terapia endovascular, en la ciudad de Manizales, Colombia, entre los años 2015 y 2021. Se describió la población estudiada, la relación de los antecedentes prequirúrgicos con las complicaciones posoperatorias, la estancia hospitalaria y la mortalidad. Resultados.La edad promedio fue de 73 años, el sexo predominante fue el femenino (72 %), el aneurisma fusiforme fue el tipo más frecuente (63,3 %), con un diámetro promedio de 70 mm (+/- 17,3 mm). En relación con los antecedentes, el más frecuente fue hipertensión arterial (86 %), encontrándose una asociación entre la presencia de enfermedad pulmonar obstructiva crónica e hipertensión arterial con las complicaciones. Se encontró también relación entre el valor de creatinina con las complicaciones. Las complicaciones tempranas fueron de carácter leve en la mayoría de los casos (30,6 %), a diferencia de las tardías, que fueron principalmente graves (12,5 %), asociadas a una mortalidad del 10,2 % y una estancia hospitalaria promedio de 10,8 días (mediana de 5 días). Conclusiones. La población analizada tiene una alta carga de morbilidad, en la cual factores como los antecedentes médicos prequirúrgicos y la función renal, se asocian con una mayor morbilidad postquirúrgica y mortalidad.
Introduction. In recent decades, endovascular therapy in abdominal aortic aneurysms has gained a representative role in surgical scenarios, which motivated us to learn about the results of this procedure in our population. Methods. Retrospective analytical study, which included the first 50 cases of abdominal aortic aneurysms with endovascular therapy, in the city of Manizales, Colombia, between 2015 and 2021. The study population was described as the relationship between pre-surgical history and post-operative complications, hospital stay and mortality. Results. The average age was 73 years, the predominant sex was female (72%), the fusiform aneurysm was the most frequent type (63.3%), with an average diameter of 70 mm (± 17.3 mm). In relation to history, the most frequent was arterial hypertension (86%), finding an association between the presence of chronic obstructive pulmonary disease and arterial hypertension with complications. A relationship was also found between the creatinine value and complications. Early complications were mild in most cases (30.6%), unlike late complications, which were mainly serious (12.5%), associated with a mortality of 10.2% and a hospital stay average of 10.8 days (median of 5 days). Conclusions. The analyzed population has a high burden of morbidity, in which factors such as pre-surgical medical history and renal function are associated with greater post-surgical morbidity and mortality.

ABSTRACT Objective Despite the development of endovascular procedures, open repair remains the gold standard for the treatment of aortic thoracoabdominal aneurysms and some type B dissections, with well-established good outcomes and long-term durability at high-volume centers. The present study described and analyzed public data from patients treated in the public system in a 12-year interval, in a city where more than 5 million inhabitants depend on the Public Health System. Methods Public data from procedures performed between 2008 and 2019 were extracted using web scraping techniques. The variables available in the database include sex, age, elective or emergency hospital admission, number of surgeries, in-hospital mortality, length of stay, and information on reimbursement values. Results A total of 556 procedures were analyzed. Of these, 60.79% patients were men, and 41.18% were 65 years of age or older. Approximately 60% had a residential address registered in the municipality. Of all surgeries, 65.83% were elective cases. There were 178 in-hospital deaths (mortality of 32%). In the elective context, there were 98 deaths 26.78% versus 80 deaths (42.10%) in the emergency context (p=0.174). Mortality was lower in the hospitals that performed more surgeries. A total of USD 3,038,753.92 was paid, an average of USD 5,406.95 for elective surgery and USD 5,074.76 for emergency surgery (p=0.536). Conclusion Mortality was no different between groups, and hospitals with higher volume presented more favorable outcomes. Specialized referral centers should be considered by health policy makers.

Abstract A primary aortic mural thrombus (PAMT) is defined as a thrombus attached to the aortic wall in the absence of any atherosclerotic or aneurysmal disease of the aorta or any cardiac source of embolus. It is a rare entity that has high morbidity and mortality. There is no consensus on the ideal treatment of PAMT. The objective of this paper is to review the possibilities for treatment of mobile abdominal aortic mural thrombus. Endovascular therapy and open surgery appear to be the best options for treatment of mobile abdominal aortic mural thrombus. Thus, in patients with favorable anatomy, endovascular therapy is probably the treatment choice, while in those with unfavorable anatomy, open surgery is probably the best option for treatment of a mobile abdominal aortic thrombus. It is important to emphasize that anticoagulation alone can be used as a non-aggressive option and, if this fails, endovascular or surgical methods can then be employed.
Resumo O trombo mural aórtico primário é definido como um trombo aderido à parede aórtica na ausência de doença aterosclerótica e/ou aneurismática ou de fonte cardíaca de êmbolo. Trata-se de uma doença rara, porém causadora de alta morbimortalidade, e não há consenso acerca do seu tratamento. Este estudo objetivou revisar as possibilidades na presença de componente móvel. A terapia endovascular e a cirurgia aberta parecem ser as melhores opções, sendo a abordagem endovascular o tratamento de escolha para pacientes com anatomia favorável e a cirurgia aberta o tratamento de escolha para pacientes com anatomia desfavorável. No entanto, a anticoagulação sistêmica apresenta-se como método não invasivo para pacientes com alto risco cirúrgico e como possibilidade terapêutica na falha ou indisponibilidade de abordagem cirúrgica.

Resumo Coarctação da aorta abdominal é uma causa rara de claudicação de membros inferiores e hipertensão refratária. O tratamento é complexo e exige conhecimento de diversas técnicas de reconstrução vascular. Apresentamos um caso de coarctação ao nível das artérias renais, seu tratamento e revisão da literatura. Paciente feminina, 65 anos, com hipertensão refratária desde os 35 anos, utilizando cinco medicações anti-hipertensivas em dose máxima. Pressão arterial média de 260/180mmHg e claudicação incapacitante (menos de 20 metros) bilateral. Angiotomografia computadorizada demonstrou coarctação de aorta justarrenal de 4 mm de maior diâmetro, calcificação circunferencial no local da estenose e tortuosidade da aorta infrarrenal. Foi submetida a tratamento híbrido, com ponte ilíaco-birrenal e implante de stent Advanta V12 no local da estenose. A paciente evoluiu satisfatoriamente e, 60 dias depois da cirurgia, apresentava-se com uma pressão arterial de 140/80mmHg, em uso de apenas duas medicações anti-hipertensivas e sem claudicação.
Abstract Coarctation of the abdominal aorta is a rare etiology of intermittent claudication and refractory hypertension. Treatment is complex and requires knowledge of several vascular reconstruction techniques. We report a case of aortic coarctation at the level of the renal arteries, describing its treatment and presenting a literature review. Female patient, 65 years old, with refractory hypertension since the age of 35, using five antihypertensive medications at maximum doses. Blood pressure was 260/180mmHg and she had disabling claudication (less than 20 meters). Computed tomography angiography showed a 4mm coarctation in the juxtarenal aorta, with circumferential calcification at the stenosis site, and tortuous infrarenal aorta. Hybrid repair was performed with an iliac-birenal bypass and implantation of an Advanta V12 stent at the stenosis site. The patient's postoperative course was satisfactory, she was free from claudication, and her blood pressure 60 days after surgery was 140/80mmHg, taking two antihypertensive medications.
