RESUMEN

BACKGROUND: Patients with peripheral arterial disease have an increased risk of developing cardiovascular complications in the postoperative period of arterial surgeries known as Major Adverse Cardiac Events (MACE), which includes acute myocardial infarction, heart failure, malignant arrhythmias, and stroke. The preoperative evaluation aims to reduce mortality and the risk of MACE. However, there is no standardized approach to performing them. The aim of this study was to compare the preoperative evaluation conducted by general practitioners with those performed by cardiologists. METHODS: This is a retrospective analysis of medical records of patients who underwent elective arterial surgeries from January 2016 to December 2020 at a tertiary hospital in São Paulo, Brazil. The authors compared the preoperative evaluation of these patients according to the initial evaluator (general practitioners vs. cardiologists), assessing patients' clinical factors, mortality, postoperative MACE incidence, rate of requested non-invasive stratification tests, length of hospital stay, among others. RESULTS: 281 patients were evaluated: 169 assessed by cardiologists and 112 by general practitioners. Cardiologists requested more non-invasive stratification tests (40.8%) compared to general practitioners (9%) (p < 0.001), with no impact on mortality (8.8% versus 10.7%; p = 0.609) and postoperative MACE incidence (10.6% versus 6.2%; p = 0.209). The total length of hospital stay was longer in the cardiologist group (17.27 versus 11.79 days; p < 0.001). CONCLUSION: The increased request for exams didn't have a significant impact on mortality and postoperative MACE incidence, but prolonged the total length of hospital stay. Health managers should consider these findings and ensure appropriate utilization of human and financial resources.

RESUMEN

Abstract Introduction: Diabetes mellitus is a chronic degenerative disease of multifactorial etiology that causes a metabolic disorder, resulting in chronic hyperglycemia, leading to microvascular and macrovascular complications in different organs. Currently, about 422 million people worldwide are living with diabetes and it is estimated that by 2045 it will affect 693 million adults. Clinical case: In this article, we report the case of a 54-year-old man with type 2 diabetes mellitus with poor adherence to treatment and with risk factors that perpetuate poor control and the incidence of complications. Conclusion: Several studies demonstrate that the higher the patient's level of understanding of the disease, the greater the adherence to the treatment strategies and the better the glycemic control, resulting in a decrease in complications. Therefore, emphasizing effective communication is always one of the best strategies to guide the diabetic patient.

Resumen Introducción: La diabetes mellitus es una enfermedad degenerativa crónica de etiología multifactorial que causa un trastorno metabólico, dando lugar a hiperglucemia crónica, lo que conlleva a complicaciones microvasculares y macrovasculares en diferentes órganos. Actualmente, alrededor de 422 millones de personas en todo el mundo viven con diabetes y se estima que en 2045 afectará a 693 millones de adultos. Caso clínico: En este artículo presentamos el caso de un varón de 54 años con diabetes mellitus tipo 2 con mala adherencia al tratamiento y con factores de riesgo que perpetúan el mal control y la incidencia de complicaciones. Conclusión: Diversos estudios demuestran que cuanto mayor es el nivel de comprensión de la enfermedad por parte del paciente, mayor es la adherencia a las estrategias de tratamiento y mejor es el control glucémico, lo que se traduce en una disminución de las complicaciones. Por lo tanto, hacer hincapié en una comunicación efectiva es siempre una de las mejores estrategias para orientar al paciente diabético.

Performed in high volume centers it has excellent results as for the prevention of new strokes.

RESUMEN

Introducción: Los aneurismas de la arteria carótida extracraneal (ACEC) son poco frecuentes en comparación con las lesiones oclusivas. Los ACEC son menos del 1% de todos los aneurismas arteriales y solo el 10% son considerados aneurismas verdaderos. Caso Clínico: Paciente femenina de 84 años, en excelentes condiciones generales, hipertensa e hiperlipidémica, neurológicamente asintomática, con hallazgo de aneurisma de carótida interna derecha en el contexto de una arteria elongada, estenosis moderada ostial y oclusión de arteria carótida interna contralateral. Se realiza resección de aneurisma con anastomosis término terminal, endarterectomía del ostium y angioplastía con parche. Su evolución fue favorable, manteniéndose asintomática y con la reconstrucción permeable a 6 meses de seguimiento en eco duplex. Discusión: La elección del manejo del ACEC va a depender de sus características morfológicas, en este caso la presencia de tortuosidad extrema de la arteria carótida interna dificultaba la posibilidad de manejo endovascular, pero facilitaba la resección del aneurisma con anastomosis primaria término terminal. Conclusión: La aneurismectomía y reconstrucción es una modalidad de manejo disponible para los ACEC.

Introduction: Extracranial carotid artery aneurysms (ECAA) are rare compared to occlusive disease, less than 1% of all arterial aneurysms and only 10% are considered true aneurysms. Clinical case: A 84-year-old female, active and in excellent general health, with a prior history significant only for hypertension and hyperlipidemia was referred for a right internal carotid artery aneurysm and elongation in the context of contralateral internal carotid artery occlusion. The patient denied neurologic symptoms. Resection of the aneurysm and end-to-end anastomosis, endarterectomy of the ostium and patch angioplasty was performed. The patient had an uneventful recovery, remaining asymptomatic and the reconstruction patent on duplex scan at 6 month follow up. Discussion: The choice of repair alternatives for EICA depend on its morphological characteristics. The presence of extreme tortuosity of the internal carotid artery in this case, on one hand make difficult to consider endovascular alternatives, but facilitates aneurysm resection and primary end-to-end anastomosis. Conclusion: Aneurysmectomy and arterial reconstruction is a treatment alternative for EICA repair.

RESUMEN

Objetivo: Describir un caso clínico y una alternativa de manejo para el tratamiento de la hemoptisis secundaria a patología la aneurismática de la aorta torácica. Materiales y Métodos: Revisión de historia clínica y exámenes complementarios, disponibles en sistema digital del centro asistencial de origen. Resultados: Se presenta el caso de paciente masculino, 56 años, que cursó con cuadro de hemoptisis, posteriormente objetivado como secundario a un pseudoaneurisma de la aorta torácica. Entre sus antecedentes destaca, enfermedad aorto-ilíaca tratada mediante un bypass de aorta torácica. Se decidió la reparación endovascular, mediante un abordaje proximal, utilizando la arteria axilar. Discusión: Las indicaciones para el uso de la reparación torácica endovascular de la aorta (TEVAR) se están expandiendo ampliamente, incluyendo a pacientes previamente intervenidos o aquellos que antiguamente se consideraban con un riesgo prohibitivamente alto para una cirugía. La fístula aorto-bronquial, es una complicación rara, sin embargo, existe correlación entre su desarrollo y la cirugía de aorta torácica. La sospecha diagnóstica debe ser alta. La AngioTC, cumple un doble rol, tanto para el diagnóstico, como para la planificación preoperatoria, hecho fundamental para conseguir una terapia adecuada.

Objective: To describe a clinical case and a management alternative for the treatment of hemoptysis secondary to thoracic aortic aneurysm pathology. Material and Method: Review of clinical history and complementary examinations, available in the digital system of the health care center of origin. Results: We present the case of a male patient, 56 years old, presented with hemoptysis, later found to be secondary to a pseudoaneurysm of the thoracic aorta. History included aorto-iliac disease treated by thoracic aortic bypass. Endovascular repair was decided by a proximal approach using the axillary artery. Discussion: Indications for the use of TEVAR are expanding widely. Including previously operated patients or those formerly considered prohibitively high risk for surgery. Aortobronchial fistula is a rare complication, however, there is a correlation between its development and thoracic aortic surgery. Diagnostic suspicion should be high. AngioCT plays a dual role in diagnosis and preoperative planning, which is essential to achieve adequate therapy.

RESUMEN

True splenic artery aneurysms are exceedingly rare and the medical literature contains only a limited number of reports on this pathology. Presently, there remains a lack of consensus regarding the optimal management and treatment approaches for patients in this category. Over the course of the last century, significant changes have occurred in the realm of surgical options, transitioning from open and endovascular procedures to the more advanced laparoscopic and robotic interventions. The propensity for these aneurysms to rupture underscores the need for timely intervention. The risk of rupture is notably elevated in patients harboring giant splenic artery aneurysms. In this report, we present the case of a 55-year-old woman diagnosed with a giant splenic artery aneurysm measuring 12x12 cm in diameter. She presented with notable weakness, discomfort, and pain in the left subcostal area. In response to her complaints and after thorough evaluation, we opted for a surgical procedure encompassing distal pancreatic resection in conjunction with splenectomy and resection of the giant splenic artery aneurysm.

Os aneurismas verdadeiros da artéria esplênica são extremamente raros, e há um número limitado de relatos sobre essa condição na literatura médica. Atualmente, não há consenso sobre as abordagens ideais de manejo e tratamento para pacientes que se enquadram nessa categoria. Ao longo do século passado, ocorreram mudanças significativas no domínio das opções cirúrgicas, passando de procedimentos abertos e endovasculares para intervenções laparoscópicas e robóticas mais avançadas. A propensão à ruptura do aneurisma ressalta a necessidade de intervenção em tempo oportuno. O risco de ruptura é notavelmente elevado em pacientes com aneurismas gigantes da artéria esplênica. Neste relato, apresentamos o caso de uma mulher de 55 anos diagnosticada com aneurisma gigante de artéria esplênica medindo 12x12 cm de diâmetro. A paciente apresentava fraqueza notável, desconforto e dor na região subcostal esquerda. Em resposta às suas queixas e após avaliação minuciosa, optamos por um procedimento cirúrgico que incluiu pancreatectomia distal associada a esplenectomia e ressecção do aneurisma gigante da artéria esplênica.

RESUMEN

An aberrant right subclavian artery (ARSA) is a rare variation of normal anatomy occurring in 0.5% to 1.8% of the population. No current guidelines are available regarding ARSA management, and surgical intervention should be evaluated carefully. Moreover, symptomatic patients with a dominant left arch and aberrant ARSA require a surgical approach from the right side of the chest for ligation and division of the aberrant artery at its origin on the aorta. The ARSA can then be reimplanted onto the right common carotid artery via a supraclavicular incision. The extensive mobilization in the chest allows for easy reimplantation in the supraclavicular region and eliminates reliance on the collateral circulation. Postoperative monitoring is reliable and easy with radial pulse examinations.

RESUMEN

Background: Previous studies indicate an inverse relationship between hospital volume and mortality after carotid endarterectomy. However, data at the level of Brazil are lacking. Objectives: To assess the relationship between hospital carotid endarterectomy procedure volumes and mortality in the state of São Paulo. Methods: Data from the São Paulo State Hospital Information System on all carotid endarterectomies performed between 2015 and 2019 were analyzed. Hospitals were categorized into clusters by annual volume of surgeries (1-10, 11-25, and ≥26). Multiple logistic regression models were used to determine whether the volume of carotid endarterectomy procedures was an independent predictor of in-hospital mortality among patients undergoing this procedure. Results: Crude in-hospital mortality was nearly 60 percent lower in patients who underwent carotid endarterectomy at the highest volume hospitals than among those who underwent endarterectomy at the lowest volume hospitals (unadjusted OR of survival to hospital discharge, 2.41; 95% CI, 1.11-5.23; p = 0.027). Although this lower rate represents 1.5 fewer deaths per 100 patients treated, high-volume centers are more likely than low-volume centers to perform elective procedures, thus the analysis did not retain statistical significance when adjusted for admission character (OR, 1.69; 95% CI, 0.74-3.87; p = 0.215). Conclusions: In a contemporary Brazilian registry, higher volume carotid endarterectomy centers were associated with lower in-hospital mortality than lower volume centers. Further studies are needed to verify this relationship considering the presence of symptoms in patients.

Contexto: Estudos indicam uma relação inversa entre volume hospitalar e mortalidade após endarterectomia carotídea. Entretanto, não há dados a nível brasileiro. Objetivos: Avaliar a relação entre volume hospitalar de endarterectomia carotídea e mortalidade no estado de São Paulo. Métodos: Foram analisados dados do Sistema de Informação Hospitalar do Estado de São Paulo de todas as endarterectomias carotídeas realizadas entre 2015 e 2019. Os hospitais foram categorizados em grupos de acordo com o volume anual de cirurgias (1-10, 11-25 e ≥26). Modelos de regressão logística múltipla foram usados para determinar se o volume de endarterectomias carotídeas era um preditor independente de mortalidade intra-hospitalar entre os pacientes submetidos a esse procedimento. Resultados: A mortalidade intra-hospitalar foi quase 60% menor nos pacientes submetidos a endarterectomia carotídea nos hospitais de maior volume em comparação aos pacientes submetidos a endarterectomia nos hospitais de menor volume (OR não ajustado de sobrevida após alta hospitalar, 2,41; IC 95%, 1,11-5,23; p = 0,027). Embora essa taxa mais baixa represente 1,5 menos mortes por 100 pacientes tratados, os centros de alto volume são mais propensos do que os centros de baixo volume a realizarem procedimentos eletivos; portanto, a análise não reteve significância quando ajustada para o caráter de admissão (OR, 1,69; IC 95%, 0,74-3,87; p = 0,215). Conclusões: Em um registro brasileiro contemporâneo, centros com maior volume de endarterectomia carotídea foram associados a menor mortalidade intra-hospitalar em comparação aos centros de menor volume. Mais estudos são necessários para verificar essa relação considerando a presença de sintomas em pacientes.

RESUMEN

Chronic kidney disease (CKD) has become a global health problem. In 2019, it was related to 2.53% of general global mortality (2.35-2.66%); in the same year, in Latin America, mortality related to CKD reached 5.25% (4.92-5.49%), with an annual increase of 3.37%, proving increased mortality of 102% between 1990 and 2017. A nephrology specialty in Mexico recently fulfilled its first 50 years. Despite being relatively young, nephrologists are interested in "new" sub-specialties of nephrology and learning novel techniques and problem-solving skills. Our group is the first in our country to focus solely and exclusively on comprehensive VA care and we want to position ourselves as the first Mexican interdisciplinary group focused on vascular access (GIMEXAV).

RESUMEN

PURPOSE: Postoperative complications after major surgery, especially vascular procedures, are associated with a significant increase in costs and mortality. Previous studies evaluating general anesthesia versus regional or neuraxial anesthesia for infrainguinal bypass have produced conflicting results. The main aim of the present study is to review current evidence on the application of regional or general anesthesia in patients undergoing infrainguinal bypass surgery and its potential favorable effects on postoperative outcomes. CONTENTS: Patients undergoing vascular surgery often have multiple comorbidities, and it is important to outline both benefits and risks of regional anesthesia techniques. Neuraxial anesthesia in vascular surgery allows overall avoidance of general anesthesia and does provide short-term benefits beyond analgesia. Previous observational studies suggest that neuraxial anesthesia for lower limb revascularization may reduce morbidity and length of stay. However, evidence of long-term benefits is lacking in most procedures and further work is still warranted. CONCLUSIONS: Neuraxial anesthesia is usually an effective anesthesia technique for infrainguinal bypass surgery. Elderly patients and those with underlying respiratory problems may display some benefit from neuraxial anesthesia. Further evaluation within institutions should be performed to identify which patients would most benefit from regional techniques. Notably, systemic antithrombotic and anticoagulation therapy is common among this population and may affect anesthetic choices.

RESUMEN

Chronic venous disease (CVD) associated with great saphenous vein (GSV) reflux has a higher prevalence of pain in the lower limbs. This study evaluates the impact of ultrasound-guided foam sclerotherapy (UGFS) for GSV and symptom control, accessed by the visual analogue scale (VAS). Patients with CVD who underwent GSV-UGFS were included in this retrospective cohort (417 limbs). The pain was measured before and after the treatment. The scale alteration was assessed as a function of age, sex, Clinical Etiologic Anatomic Pathophysiologic (CEAP) classes, total of sclerotherapy sessions, GSV occlusion patterns, and ulcer healing. Majority of patients were female (59.2%), and the mean age was 56 ± 11.5 years. In the total sample, 78.2% of the GSVs were fully occluded, 19.7% had partial occlusion, 2.2% remained open, and 3.2 ± 1.9 (median = 3.0) sessions were performed. The reduction of symptoms occurred in 88.3% of participants (VAS drop median = 4.8). Patients younger than 50 years and females had the greatest VAS decreases. When comparing the outcomes of complete occlusion versus partial occlusion, there was no significant difference in VAS pain reduction ( p = 0.14). The comparison between CEAP clinical classes also did not show statistically significant differences in delta VAS ( p = 0.71). GSV-UGFS was effective for pain control. However, this improvement does not appear to be related to the pattern of occlusion, indicating that in the short term, the outcomes of total and partial occlusion suggest successful management of symptoms. Other aspects such as gender, age, pretreatment pain intensity, and CEAP classes seem to play a role in the clinical outcome.

RESUMEN

Introducción: La baja incidencia del leiomiosarcoma de la vena cava inferior dificulta tanto la estandarización del diagnóstico como el tratamiento. Objetivo: Presentar el manejo realizado en nuestro centro de un paciente que desarrolló un leiomiosarcoma de vena cava inferior, una patología de baja incidencia y que las posibilidades de realizar un rescate quirúrgico son muy bajas. Resultados: Se presenta el caso de un paciente de 54 años con una tumoración sólida en porción infrarrenal y yuxtarrenal de vena cava inferior de 71 × 76 × 117 mm compatible con leiomiosarcoma de vena cava, con infiltración de uréter derecho que ocasiona uropatía obstructiva derecha grado I-II sin alteración de la función renal, que fue resecada y reconstruida mediante prótesis sin complicaciones. Discusión: Se discute la fisiopatología, el diagnóstico y manejo en relación con el caso presentado. Conclusión: la baja incidencia de estos tumores dificulta tanto la estandarización del diagnóstico como del tratamiento, aunque la cirugía sigue siendo el tratamiento de elección.

Introduction: The low incidence of leiomyosarcoma of the inferior vena cava hinders both the standardization of diagnosis and treatment. Objective: To present the management carried out in our center of a patient who developed an inferior vena cava leiomyosarcoma, a low incidence pathology with uncertain surgical rescue. Results: 54-year-old patient with a solid tumor in the infrarenal and juxtarenal portions of the inferior vena cava of 71 × 76 × 117 mm compatible with leiomyosarcoma of the vena cava, with infiltration of the right ureter that causes right obstructive uropathy grade I-II without kidney function changes; tumour was resected and continuity reconstructed with a prosthesis without complications. Discussion: The pathophysiology, diagnosis and management are commented. Conclusion: the low incidence of these lesions makes it difficult to standardize both diagnosis and treatment, although surgery remains the treatment of choice.

RESUMEN

OBJECTIVE: The COVID-19 (coronavirus disease 2019) pandemic has led to a rapid expansion in the use of telemedicine across all medical fields but has also exposed telehealth care disparities with differing access to technology across racial and ethnic groups. The objective of our study was to investigate the effects of telehealth on vascular visit compliance and to explore the effects of sociodemographic factors on vascular surgery outpatient telehealth usage during the COVID-19 pandemic. METHODS: Consecutive patients who had undergone an outpatient vascular surgery evaluation between February 24, 2020 (the launch of our telemedicine program) and December 31, 2020, were reviewed. The baseline demographic and outcomes were obtained from the electronic medical records. Telehealth and in-person evaluations were defined according to the patient's index visit during the study period. Medical visit compliance was established on completion of the telehealth or in-person encounter. We used χ2 tests and logistic regression analyses. RESULTS: A total of 23,553 outpatient visits had been scheduled for 10,587 patients during the study period. Of the outpatient visits, 1559 had been scheduled telehealth encounters compared with 21,994 scheduled in-person encounters. Of the scheduled outpatient encounters, 13,900 medical visits (59.0%) had been completed: 1183 telehealth visits and 12,717 in-person visits. The mean travel distance saved for the telehealth visits was 22.1 ± 27.1 miles, and the mean travel time saved was 46.3 ± 41.47 minutes. We noted no sociodemographic differences between the patients scheduled for telehealth vs in-person visits. We found a trend toward a lower proportion of African-American patients in the telehealth group vs the in-person group (7.8% vs 10.6%; P = .116), without statistical significance. A significantly higher rate of medical visit completion was found for the telehealth group compared with the in-person group (79.5% vs 59.4%; P < .001). Among the patients scheduled for an outpatient medical visit, a scheduled telemedicine evaluation (vs in-person) was associated with 2.3 times the odds of completing the medical visit (odds ratio, 2.31; 95% confidence interval, 2.05-2.61), adjusting for age, sex, race, ethnicity, language, and the distance between the patient's home zip code and the outpatient vascular center's zip code. Selecting for scheduled telemedicine visits, African-American race was associated with a decreased odds of telemedicine usage (odds ratio, 0.73; 95% confidence interval, 0.59-0.90) after adjusting for age, sex, ethnicity, language, and visit type. CONCLUSIONS: Use of the vascular surgery outpatient telehealth evaluation appeared to improve medical visit completion in our region with apparent sociodemographic disparities. Further studies are needed to confirm whether telemedicine expansion has improved access to care in other geographic areas.

RESUMEN

A 57-year-old man was diagnosed with acute myocardial infarction and Stanford type A aortic dissection that had spread to the common iliac arteries. He underwent a Bentall procedure for vascular repair. Immediately after surgery, he developed numbness and severe weakness in his left leg. On examination, he had hypotonia, absent deep tendon reflexes, weakness in the left leg (Medical Research Council (MRC) scale for muscle strength - 0/5 distal, 3/5 proximal) and reduced sensation in the left leg. Electromyography confirmed subacute involvement of the left lumbar and lumbosacral plexus. MR scan of the lumbar plexus showed diffuse muscle oedema involving the left gluteus maximus. We diagnosed ischaemic lumbosacral plexopathy secondary to extensive aorta dissection and internal iliac artery occlusion. We discuss the clinical features of ischaemic plexopathy and the diagnostic approach and review the vascular anatomy of the lumbosacral plexus.

Neste relato, apresentamos o caso de uma mulher de 55 anos diagnosticada com aneurisma gigante de artéria esplênica medindo 12x12 cm de diâmetro. A paciente apresentava fraqueza notável, desconforto e dor na região subcostal esquerda. Em resposta às suas queixas e após avaliação minuciosa, optamos por um procedimento cirúrgico que incluiu pancreatectomia distal associada a esplenectomia e ressecção do aneurisma gigante da artéria esplênica.

RESUMEN

We have reported a case of a 36-year-old woman with flank and pelvic pain and hematuria. She had posterior nutcracker syndrome and pelvic varices involving one anterior and three posterior renal veins (including one major vein). We used a complete endovascular approach, which included stent implantation in the major posterior renal vein and left gonadal vein embolization. During a 12-month follow-up period, the patient had had no symptoms and good computed tomography results. Endovascular treatment represents a safe and successful option for patients with nutcracker syndrome and pelvic varices involving the anterior and posterior renal veins.

RESUMEN

We present a case of a thoracic aortic mural thrombus (AMT) in a non-atherosclerotic and non-aneurysmal aorta that presented with acute limb ischaemia. AMT in a non-diseased aorta without an underlying hypercoagulable disorder is rare. The AMT in our patient was managed with anticoagulation, which resolved on a 5-month follow-up CT scan. This provided us an opportunity to discuss the successful medical management of an AMT, to review the literature on the management of AMT and to add to the literature on a rare presentation of an AMT.
