“…Regarding the patient studied, partial lesion of the great saphenous vein was observed, which originates in the first toe, passing anteriorly through the internal malleolus, rising up the inner side of the leg, reaching the knee and performing internal ramifications until it united with the femoral vein 18 . Therefore, it can be concluded that this lesion originated from the stingray sting which, due to its sharp characteristics, grooves and jagged ends, allied to the region in which the sting was performed, showed exposure of the great saphenous vein.…”

Introduction: Fish accidents, called ichthyism, are common and considered a neglected health problem with high morbidity and low lethality. Noteworthy are the poisonings by freshwater stingrays, which are considered very serious and one of the most important injuries caused by aquatic animals in South America. Case Presentation: To describe an accident and vascular injury with venomous stingray animals in the Alto do Juruá, Acre, Brazil. Male patient admitted due to stingray in the left lower extremity 20 days ago. Conclusion: The freshwater stingray, due to its sharp characteristics, injured the great saphenous vein, requiring surgical intervention. The situation presented negative evolution due to the lack of necessary procedures in the first attendance, such as the proper cleaning of the wound and the removal of the sting.

“…We have tried to classify the variants of hypoand aplastic GSV segment localization and extension according to the already known classifications. According to the classification of GSV aplasia described by Seidel A.C. et al (2012), there are 6 types of GSV aplasia: Type I -aplasia only in the thigh segment; Type II -aplasia in the tibial segment; Type III -aplasia in the distal segment of the thigh and the proximal segment of the tibia; Type IV -aplasia of the whole tibial segment; Type V -aplasia of the whole tibial segment and a significant part of the thigh segment without involving a short proximal segment; Type VI -aplasia of the entire vein without involving a short segment in the tibia [11,12]. According to the most common classification of GSV hypoplasia described by Caggiati A., Mendoza E. (2004), there are the following types of GSV hypoplasia: A -normally sized GSV segments join the suprafascial branch; B -distal GSV segment drains into the perforating vein; C -hypoplasia of the tibial part of the GSV; D -hypoplasia of the proximal part of the GSV which is shunted in the anterior accessory GSV [13].…”

The objective of the research was to improve the diagnostics and treatment of patients with primary varicose great saphenous veins by studying their frequency and systematizing the variants of localization and extension of great saphenous vein hypoplasia and aplasia in its trunk. Materials and Methods. The study included 560 patients with varicose veins of the lower limbs and pathological refluxes in different segments of the great saphenous vein. All the patients underwent triplex ultrasound scan of the lower limb venous system. Results. Among the patients with pathological reflux in a certain GSV segment, hypo- and aplasia of its segments were observed in 32.5% of the cases (95% CI 28.6-36.6%). Aplasia of this vein was observed twice as less frequently than hypoplasia (p<0.05). In 2.3% of the cases (95% CI 1.2-3.9%), hypoplasia of a certain GSV segment evolved to aplasia, or vice versa. It was found that the GSV trunk may have several hypo- or aplastic regions separated by its normal or varicose segment – bi-level hypo- or aplasia that was observed in 3.8% of the patients with hypo- or aplasia (95% CI 1.6-7.8%). In bi-level hypo- or aplasia, 2 hypoplastic regions were detected in 85.7% of the cases (95% CI 42.1-99.6%) and 2 aplastic regions were found in 14.3% of the cases (95% CI 0.4-57.9%). There were proposed to distinguish the following variants of GSV hypo- and aplasia: 1) simple: total, proximal, segmental and distal; 2) bi-level: proximal segmental, distal segmental and bi-segmental. In addition, for every dysplastic vein segment, the type of malformation should be indicated, namely hypoplasia, aplasia, or hypo/aplasia. Conclusions. The study conducted allowed assessing the relationship between the variants of GSV hypo- and aplastic segment localization and extension and different variations of pathological refluxes of the GSV in its trunk for further choice of surgical tactics.

“…Em uma amostra de 1408 pacientes, na qual foram examinados 2.665 membros inferiores, Seidel et al, 4 relatam aplasia de VSM em 61,8% no grupo sem varizes e em 38,2% dos membros com varizes. O resultado desse estudo mostrou que no grupo com varizes houve uma maior incidência de membros com associação de insuficiência e aplasia de VSM em relação ao grupo sem varizes.…”

“…A USV representa o principal método propedêutico na avaliação morfo-funcional das varizes dos membros inferiores, incluindo a VSM, sendo que a correta avaliação do sistema venoso através desse método é importante para o manejo da doença. 2 Embora estudos demonstrem uma associação entre a presença de variação anatômica e insuficiência da VSM, 2 outros estudos não corroboram tais achados, 3,4 tornando o tema ainda controverso.…”

Introdução: A anatomia venosa pode apresentar significativa variabilidade, com ampla incidência de afluentes venosos, veias duplicadas, tributárias ou acessórias relacionadas às veias safenas. O reconhecimento e a identificação destas variações são importantes no manejo terapêutico destes pacientes, sendo que a ultrassonografia vascular é o método de escolha na avaliação do sistema venoso periférico. Objetivos: avaliar a associação entre variação anatômica da veia safena magna (VSM) e insuficiência venosa dos membros inferiores em pacientes com varizes primárias dos membros inferiores. Métodos: Foram avaliados consecutivamente pacientes com clínica de varizes de membros inferiores no período de 2014 a 2015, excluindo pacientes com história de cirurgia prévia e trombose venosa profunda. A ecografia vascular foi realizada para exame do sistema venoso superficial, em especial ao estudo da VSM, determinando os diversos padrões de variação anatômica deste vaso e sua associação com a presença de insuficiência venosa e classificação CEAP. Resultados: foram examinados 422 membros inferiores de 211 pacientes, com idade entre 21 e 86 anos, média de 45,7 anos, sendo 81% do sexo feminino, com predomínio de CEAP 1 (43,8%) e 2 (46,2%). Refluxo na VSM foi encontrado em 35,1%. A presença de variação anatômica foi encontrada em 8,8% dos pacientes sendo mais frequente em terço distal da coxa e proximal da perna (27,3%), não sendo observado associação entre a variação anatômica da VSM e CEAP (p = 0,25). Observou-se associação estatisticamente significativa entre ausência de variação anatômica e de insuficiência de VSM (p = 0,03). Conclusão: no presente estudo observou-se variação anatômica da veia safena magna em cerca de 9% dos pacientes, com associação significativa entre insuficiência de veia safena magna e ausência de variação anatômica.
