RESUMO
Variations in the drainage (termination) and course of the lower limb veins are not uncommon. When dissecting the left lower limb of the adult male cadaver in the vascular case described herein, a unique kind of unilateral short saphenous vein (SSV) termination was observed. It was found that the SSV had normal origin and course in the dorsum of the foot and the back of the leg, respectively. Most often the SSV terminates in the popliteal vein at the popliteal fossa. In this case, it extended upward into the back of the thigh, passing behind the sciatic nerve and then deep to it and the biceps femoris, and finally ended in the veins of the thigh. The SSV did not penetrate any structures along its course to the end, so this unusual vein appears unlikely to be associated with SSV varicose veins. For general, plastic, cardiothoracic, and vascular surgeons, our case would be of significant value.
Variações na drenagem (terminação) e curso das veias dos membros inferiores não são incomuns. No caso vascular relatado, ao dissecar o membro inferior esquerdo de um cadáver adulto do sexo masculino, foi observado um tipo único de veia safena parva (VSP) unilateral. Verificou-se que a VSP tinha origem e curso normais no dorso do pé e na traseira da perna, respectivamente. É mais comum a VSP terminar na veia poplítea, localizada na fossa poplítea. No caso relatado, ela se estendia para cima até a parte posterior da coxa, passando por trás e profundamente no nervo ciático e no músculo isquiotibial, finalizando nas veias da coxa. A VSP não penetra nenhuma estrutura no seu curso; portanto, não é provável que esta veia incomum esteja associada a veias varicosas da VSP. Para cirurgiões gerais, plásticos, cardiotorácicos e vasculares, nosso caso é de extrema importância.

RESUMO
Venous varicose of epidura is considered a rare cause of nerve root and thecal sac compression and impingement that leads to lower limb radiculopathy. The purpose of this study is to draw attention to this problem during operation. It also aims to focus shed a light on using magnetic resonance imaging (MRI) before the operation. This research also attempts to evaluate the outcome of the surgery. Symptoms of epidural varicose with radiculopathy are rare and the diagnosis is often inaccurate by preoperative clinical examination and radiology investigations. Thus, in many cases the diagnosis is made intra- operatively. The case was a 40 years old female who consulted our outpatient clinic complaining from acute radicular pain in the lower back and down of her right lower limb. MRI was done for her and showed paracentral disc herniation. Intra operatively, an abnormal dilatation of epidural vein impingement on L4 nerve root with no foraminal stenosis was seen. We initiated a thermo coagulation of the epidural vein from proximal to distal ends at disc level and used gel foam patch to control bleeding that was removed all at the end of operation. Then, coagulation ablation was performed. The operation resulted in relief of symptoms and neurologic recovery occurred during follow up period. According to our case and previously published case reports, the outcome is good with recovery of neurological signs and symptoms that can be obtained by coagulation ablation of epidural varicose vein.

OBJECTIVE: Lower extremity varicose veins have a high prevalence and can be associated with significant morbidity in their more advanced presentations; overweight patients tend to present with more severe clinical symptoms and conventional surgical treatment remains challenging. Although the advent of ultrasound-guided foam sclerotherapy (UGFS) increased the treatment options for these patients, the need for elastic compression after UGFS remains controversial. METHODS: Overweight patients with lower extremity varicose veins secondary to great saphenous vein reflux were treated with UGFS and then randomized to use or no use of a 3-week treatment of elastic compression stockings. Follow-up was performed by clinical evaluation and duplex ultrasound examination. The primary outcome measure was the absence of venous reflux in the great saphenous vein. RESULTS: One hundred thirty-five lower limbs were treated; 72 limbs were randomized to elastic compression and 63 limbs to the control group. There were no statistically significant differences in the number of procedures (P = .64) or the mean foam volume per procedure (P = .27) between groups. There was no difference in the reflux rate at either 3 weeks (26% vs 35%; P = .16) or 3 months (25% vs 21%; P = .85). Major complications were venous deep thrombosis (n = 2), neurologic event (n = 1), and ischemic ulceration (n = 1); the overall rate was 3% in both groups-2 of 62 in control patients and 2 of 69 in compression patients (P = .45). Venous diameter reduction was noted in both groups during treatment (P < .05) but with greater decrease in greater saphenous vein diameter in patients treated with compression. CONCLUSIONS: Elastic compression stockings for 3 consecutive weeks after UGFS in overweight patients did not decrease great saphenous vein reflux, need for repeat procedures, or the volume of foam injected. However, UGFS was associated with a greater and uniform reduction in saphenous vein diameter at all times after the procedure.

Resumen: ANTECEDENTES: La ruptura de una variz útero-ovárica durante el embarazo es un evento poco frecuente, pero con importantes implicaciones en la morbilidad y mortalidad materna y neonatal. Puede acontecer en cualquier momento del embarazo, aunque su frecuencia se incrementa en el tercer trimestre y durante el parto. CASO CLÍNICO: Paciente de 32 años, con 39 semanas de embarazo, en control prenatal, sin contratiempos, que acudió al servicio de Urgencias debido a un dolor abdominal generalizado e intenso, de dos horas de evolución. A la exploración física se encontraron: hipotensión, taquicardia y anemia moderada; hemoglobina de 8.9 g/dL y hematócrito de 35%. La evaluación fetal reportó: taquicardia y posterior bradicardia. Se decidió finalizar el embarazo por cesárea urgente, donde se objetivó hemoperitoneo de aproximadamente 1 L y sangrado activo procedente de la ruptura de un vaso en la parte posterior de la pared uterina que se suturó con puntos dobles. El desenlace materno y neonatal fue favorable. CONCLUSIONES: La rotura de las várices útero-ováricas puede originarse por hemoperitoneo masivo y resultar en consecuencias graves para la madre y el feto. La sospecha diagnóstica y la laparotomía de urgencia son decisivas para cohibir el sangrado y lograr un desenlace materno y fetal satisfactorios.
Abstract: BACKGROUND: The rupture of an utero-ovarian varicose vein during pregnancy is an infrequent event but it can have important implications for maternal and neonatal morbidity and mortality. It can occur at any time during pregnancy, although its frequency is increased in the third trimester and during labor. CLINICAL CASE: A single gestation of 39 weeks, with regular monitoring without incidents, who went to the emergency department for intense and generalized abdominal pain of two hours of evolution. The patient presented hypotension and tachycardia and moderate anemia with a hemoglobin of 8.9 g/dL and a hematocrit of 35%. Fetal monitoring showed fetal tachycardia with decreased variability and subsequent bradycardia. It was decided to end the pregnancy by an urgent caesarean section where a hemoperitoneum of approximately 1 liter was observed. As well, and active bleeding resulting from the rupture of a posterior uterine wall vein was noted and controlled with hemostatic sutures. The maternal and neonatal results were favorable. CONCLUSIONS: Spontaneous rupture of utero-ovarian varicose veins can be the cause of massive hemoperitoneum and can maternal and fetal serious consequences. A promptly suspected diagnosis and an urgent laparotomy are vital to restrain bleeding and achieve a good maternal and fetal result.
RESUMO
Resumen ANTECEDENTES: El síndrome Klippel-Trenaunay es neurocutáneo, con repercusión vascular. La triada característica la integran: nevo vascular cutáneo, venas varicosas e hipertrofia asimétrica de los tejidos blandos y huesos que afectan una o más extremidades. Durante el embarazo estas malformaciones se incrementan, con afectación pélvica e intraabdominal. En la bibliografía internacional están reportados menos de 100 casos de embarazos complicados con este síndrome. CASO CLÍNICO: Paciente de 16 años, primigesta, con síndrome Klippel-Trenaunay diagnosticado a los 15 años, enviada a nuestra unidad, en el tercer trimestre del embarazo, para finalización de éste. Se le practicaron estudios preoperatorios: biometría hemática, pruebas de coagulación, reportados sin alteraciones. El ultrasonograma Doppler del segmento uterino sin incremento en la vasculatura. Se programó para cesárea, que se llevó a cabo sin complicaciones intraoperatorias, con sangrado de 600 cc, incremento de la vascularidad en el colon. Permaneció en vigilancia durante 48 horas, luego de la operación, en cuidados intensivos, sin complicaciones hemorrágicas o isquémicas. Se dio de alta del hospital a las 72 horas, con tromboprofilaxis, analgésico y antibiótico. CONCLUSIÓN: El embarazo en pacientes con síndrome de Klippel-Trenaunay implica una elevada morbilidad y mortalidad, que pueden prevenirse con atención multidisciplinaria que disminuya las potenciales complicaciones.
Abstract BACKGROUND: Klippel-Trenaunay syndrome is a neurocutaneous syndrome with vascular repercussion whose characteristic triad is a cutaneous vascular nevus, varicose veins and asymmetric soft tissue and bone hypertrophy, which affect one or more limbs, during pregnancy these malformations increase, with pelvic and intra-abdominal repercussion. In the world literature, fewer than 100 cases of complicated pregnancies with this syndrome have been reported. OBJECTIVE: The second case of complicated pregnancy with Klippel-Trenaunay syndrome treated in our institution is reported, given its high morbidity, due to the high risk of severe complications such as venous thromboembolism or excessive bleeding in the intrapartum period. CLINICAL CASE: A 16-year-old, with a Klippel-Trenaunay syndrome diagnosed at fifteen, sent to our unit, with a third-trimester pregnancy, for resolution of pregnancy. Preoperative studies were performed blood count, coagulation tests, reported without alterations; as well as Doppler ultrasound of the uterine segment, without an increase in vasculature. It is scheduled for caesarean section, which is performed without intraoperative complications, with total bleeding of 600 cc, with an increase in vascularity at the colon level. She remains in immediate postoperative surveillance for 48 hours in an intensive care unit, without presenting haemorrhagic or ischemic complications. She is discharged at 72 hours, with thromboprophylaxis, analgesic and antibiotic. CONCLUSION: Pregnancy in patients with this syndrome implies high morbidity and mortality, which can be prevented with multidisciplinary management, anticipating potential complications.
RESUMO
OBJECTIVES: In varicose veins, vascular smooth muscle cells (VSMCs) often shows phenotypic transition and abnormal proliferation and migration. Evidence suggests the FOXC2-Notch pathway may be involved in the pathogenesis of varicose veins. Here, this study aimed to explore the role of long non-coding RNA FOXC2-AS1 (FOXC2 antisense RNA 1) in phenotypic transition, proliferation, and migration of varicose vein-derived VSMCs and to explore whether the FOXC2-Notch pathway was involved in this process. METHODS: The effect of FOXC2-AS1 on the proliferation and migration of human great saphenous vein smooth muscle cells (SV-SMCs) was analyzed using MTT assay and Transwell migration assay, respectively. The levels of contractile marker SM22α and synthetic marker osteopontin were measured by immunohistochemistry and Western blot to assess the phenotypic transition. RESULTS: The human varicose veins showed thickened intima, media and adventitia layers, increased synthetic VSMCs, as well as upregulated FOXC2-AS1 and FOXC2 expression. In vitro assays showed that FOXC2-AS1 overexpression promoted phenotypic transition, proliferation, and migration of SV-SMCs. However, the effect of FOXC2-AS1 overexpression could be abrogated by both FOXC2 silencing and the Notch signaling inhibitor FLI-06. Furthermore, FOXC2-AS1 overexpression activated the Notch pathway by upregulating FOXC2. CONCLUSION: FOXC2-AS1 overexpression promotes phenotypic transition, proliferation, and migration of SV-SMCs, at least partially, by activating the FOXC2-Notch pathway.

There is considerable debate in the literature with relation to the best method to treat patients with chronic venous disease (CVD). CHIVA is an office-based treatment for varicose veins performed under local anesthesia. The aim of the technique is to lower transmural pressure in the superficial venous system and avoid destruction of veins. Recurrence of varicosities, nerve damage, bruising and suboptimal aesthetic results are common to all treatments for the disease. This paper evaluates and discusses the characteristics and results of the CHIVA technique. We conclude that CHIVA is a viable alternative to common procedures that is associated with less bruising, nerve damage, and recurrence than stripping saphenectomy. The main advantages are preservation of the saphenous vein, local anesthesia, low recurrence rates, low cost, low pain, and no nerve damage. The major disadvantages are the learning curve and the need to train the team in venous hemodynamics.
Existe uma grande discussão na literatura sobre o tratamento da doença venosa crônica (DVC). A cura conservadora e hemodinâmica da insuficiência venosa em ambulatório (CHIVA) consiste no tratamento ambulatorial de varizes sob anestesia local. O objetivo da técnica é diminuir a pressão transmural no sistema venoso superficial para evitar a destruição das veias, incluindo as veias safenas. Recorrência de varizes, lesão de nervos, hematomas e resultado estético abaixo do ideal são uma constante em todos tratamentos de varizes. O objetivo desta revisão é avaliar e discutir a técnica CHIVA quanto a suas características e resultados. A CHIVA é uma alternativa válida frente aos outros procedimentos, apresentando menos hematomas, recorrência e lesão nervosa que a safenectomia. Preservação da veia safena, anestesia local, baixa taxa de recorrências, baixo custo, pouca dor e ausência de lesões nervosas são as principais vantagens. A longa curva de aprendizado para treinar a equipe em hemodinâmica venosa é a principal desvantagem.

Resumen 20. La enfermedad varicosa es un problema común que afecta a gran parte de la población mundial, principalmente en mujeres, agravado por una condición de embarazo. Esta revisión narrativa tiene el objetivo de conocer la evidencia científica disponible sobre aspectos diagnósticos, factores de riesgo e intervención conservadora o invasiva, incluyendo cirugía de las venas varicosas en miembros inferiores en mujeres embarazadas. La búsqueda bibliográfica se llevó a cabo en las bases de datos PubMed, Biblioteca Cochrane y EBSCO Host entre los años 2009 y 2017. Se recuperó 50 referencias bibliográficas y se seleccionó seis documentos para el análisis. Respecto del diagnóstico se lleva a cabo mediante la observación, examen directo, historia clínica y exámenes más específicos como el doppler. La síntomatología más común que se presenta es el dolor en miembros inferiores, edema, pesadez, prurito y calambres. La intervención para el tratamiento a mujeres embarazadas es la terapia conservadora, aunque solo en casos excepcionales se determinará otro tipo de tratamiento. En este proceso, la educación tiene un rol muy importante en la seguridad de la madre y el feto, cuyo abordaje debe ser dado por un equipo de profesionales en salud. Se concluye que existe controversias respecto de la patogenia de esta morbilidad durante el embarazo, por lo tanto, no se ofrece otros tratamientos distintos a los recomendados desde el año 50, de manera que hay una gran necesidad de llevar a cabo estudios robustos que demuestren cuáles son las mejores medidas profilácticas más novedosas y de tratamiento desde el inicio del embarazo, además de promover la prevención de la aparición posterior, de tal manera que esté asegurada la salud de la mujer y, consecuentemente, la de su bebé.
Abstract 24. The varicose disease is a common problem that affects a large part of the world population in greater percentage of women, added to its condition the presence of pregnancy. This narrative review has the objective of knowing the available scientific evidence on diagnostic aspects, risk factors and conservative or invasive intervention including surgery of varicose veins in lower limbs in pregnant women. The bibliographic search was carried out in PubMed, Cochrane Library and EBSCO Host databases between 2009 and 2017. Fifty bibliographical references were retrieved and six documents were selected for analysis. Regarding the diagnosis is carried out through observation, direct examination, clinical history, more specific examinations such as Doppler. The most common symptom presented is a pain in the lower limbs, oedema, heaviness, pruritus and cramps. The intervention for the treatment of pregnant women is conservative therapy, only in exceptional cases will be determined another type of treatment. Education plays a very important role in the safety of the mother and the fetus. The approach to these women must be given by a team of health professionals. It is concluded that there are controversies regarding the pathogenesis of this morbidity during pregnancy and, therefore, no treatments other than those recommended since year 50 are offered, so there is a great need to carry out robust studies that show which are the best new prophylactic measures and treatment from the beginning of pregnancy, in addition to promoting the prevention of subsequent appearance, in such a way that the health of the woman and consequently that of her baby is ensured.
Resumo 28. A doença varicosa é um problema comum que afeta uma grande parte da população mundial em maior porcentagem para as mulheres, adicionou à sua condição a presença de gravidez. Esta revisão narrativa tem como objetivo conhecer as evidências científicas disponíveis sobre aspectos diagnósticos, fatores de risco e intervenção conservadora ou invasiva, incluindo cirurgia de varizes em membros inferiores em mulheres grávidas. A pesquisa bibliográfica foi realizada nas bibliotecas PubMed, Cochrane Library e EBSCO Host entre 2009 e 2017. Cinquenta referências bibliográficas foram recuperadas e 6 documentos foram selecionados para análise. Quanto ao diagnóstico é realizado através da observação, exame direto, história clínica, exames mais específicos, como Doppler. O sintoma mais comum apresentado é a dor nos membros inferiores, edema, peso, prurido e cólicas. A intervenção para o tratamento de mulheres grávidas é a terapia conservadora, apenas em casos excepcionais será determinado outro tipo de tratamento. A educação desempenha um papel muito importante na segurança da mãe e do feto. A abordagem dessas mulheres deve ser dada por uma equipe de profissionais de saúde. Conclui-se que há controvérsias quanto à patogenia desta morbidade durante a gravidez e, portanto, não são oferecidos outros tratamentos além dos recomendados desde o ano 50, por isso há uma grande necessidade de realizar estudos robustos que mostrem quais são as melhores medidas profiláticas novas e o tratamento desde o início da gravidez, além de promover a prevenção da aparição subseqüente, de tal forma que seja assegurada a saúde da mulher e conseqüentemente a de seu bebê.

Objective To analyze the outcomes of 119 (188 feet) patients undergoing foot varicose vein phlebectomy with and without sclerotherapy between 2013 and 2015. Methods Legs and feet were treated in one single procedure. Clinical and ultrasound assessments were carried out at 7, 30, and 90 days for visualization of the sapheno-femoral and sapheno-popliteal junctions and the deep vein system. Results Mean age was 50 ± 12 years (25-79 years); 67 patients were female (56.3%). Median venous clinical severity score was 4 (range 2-5) before and 1 (range 0-2) at 90 days ( p < 0.001). Edema and transient paresthesia were the most frequent complications (13 (10.92%) and 11 (9.24%) patients, respectively). All complications were resolved at 90 days except one case of edema (resolved after 150 days with compression stockings and lymphatic drainage manual therapy). Conclusions Symptomatic foot varicose vein intervention was safe and effective. Further studies should focus on assessment of vein-specific quality of life questionnaires.

Introduction: Pelvic congestion syndrome (PCS) is produced by anomalous flow in ovarían veins. Direct venography (DV) is the gold-standard for diagnosis. Phase-Contrast Magnetic Resonance Angiography (PC-MRA) appears as an alternative that would permit a morphological and functional assessment. The purpose of the study was to evaluate the usefulness of flow velocity (measured with PC-MRA) as a diagnostic criterion and also to compare it with the DV technique. Patients and methods: We prospectively included 8 female patients with clinical suspicion of PCS who were referred for undergoing DV over a six-month period. PC-MRA examinations were performed in all of them. Slow anterograde or retrograde flow were the diagnostic criteria. Sensitivity, specificity, PPV, and NPV were also calculated. Results: Data from 16 veins were analized by means of a home-made software written in Matlab. There were 12 abnormal and 4 normal veins according to DV results. All the abnormal veins were correctly identified by MR-PC. Two veins (corresponding to the same patient) were considered as normal in accordance with DV results, whereas the PC-MRA analysis revealed them as abnormal veins. This patient presented with PCS typical symptoms. Sensitivity and specificity values were 100 and 50 percent, respectively, whereas PPV and NPV values were 86 and 100 percent, respectively. Conclusion: PC-MRA is a useful diagnostic tool for patients with clinical suspicion of PCS and could avoid unnecessary invasive procedures.
Introducción: El síndrome de congestión pelviana (SCP) es producido por flujo anómalo en las venas ováricas. La venografía directa (VD) es el estándar de referencia. La resonancia magnética con contraste de fase (MR-CF) permitiría una evaluación morfológica y funcional. El propósito fue evaluar la utilidad de la velocidad de flujo medida con RM-CF como criterio diagnóstico comparado con VD. Pacientes y Métodos: Incluimos prospectivamente 8 pacientes derivadas para VD por sospecha de SCP durante 6 meses; todas fueron sometidas a RM-CF. Los criterios diagnósticos fueron: flujo retrógrado o anterógrado lento. Se calculó sensibilidad, especificidad, VPP y VPN. Resultados: Analizamos los datos de 16 venas, utilizando un software propietario escrito en Matlab. Hubo 12 venas anormales y 4 venas normales en VD. Todas la venas anormales fueron correctamente identificadas por MR-PC. Dos venas (la misma paciente) fueron normales en VD y anormales en MR-PC. Esta paciente tenía clásicos síntomas de SCP La sensibilidad fue de 100 por ciento, especifidad de 50 por ciento, VPP de 86 por ciento y VPN de 100 por ciento Discusión: MR-PC es una herramienta útil en el diagnóstico del SCP y evitaría exámenes invasivos innecesarios.
