Resumo

Contexto: A veia de Giacomini (VG) pode transferir refluxo de veias perineais, veias tributárias e veias perfurantes da coxa para a veia safena parva (VSP). A ultrassonografia vascular com Doppler (USVD) é o exame de escolha para detecção do refluxo em veias específicas como a VG.

Objetivos: Identificar a profundidade, o diâmetro e o refluxo na VG e a presença de refluxo na VSP causado pela VG.

Métodos: Estudo transversal e retrospectivo, em mulheres que realizaram mapeamento venoso para cirurgia de varizes de membros inferiores. Nas VGs com refluxo, foram considerados os seguintes parâmetros: refluxo segmentar ou difuso; diâmetro, profundidade; e refluxo na VSP causado pela VG.

Resultados: Das 2.368 mulheres avaliadas, 340 foram incluídas no estudo por apresentarem VG, totalizando 511 veias analisadas, sendo 150 (29,4%) veias com refluxo. Nas 150 VGs com refluxo, o diâmetro variou entre 1,5 e 7,8 mm e a profundidade, entre 4 e 25 mm. O padrão de refluxo na maioria das VGs (91,3%) foi do tipo segmentar. Em relação à drenagem do refluxo das VGs, a maioria (66%) drenou o refluxo para a veia poplítea através da junção safenopoplítea; em 34 veias (22,7%), o refluxo foi transferido para a VSP e, em 15 veias (11,3%), foi escoado por veia tributária na coxa.

Conclusões: Aproximadamente um terço das VGs estudadas apresentou refluxo, majoritariamente segmentar, com calibre médio de 2,7 mm e profundidade média de 11 mm. Refluxo na VSP originado da VG foi detectado em 22% das veias avaliadas.

Abstract

Background: The Giacomini vein (GV) can transfer reflux from perineal veins, tributary veins, and perforators of the thigh to the small saphenous vein (SSV). Vascular ultrasound with Doppler (VUD) is the preferred method for detecting reflux in specific veins such as the GV.

Objective: To identify GV depth and diameter, reflux in the GV, and presence of reflux in the SSV caused by the GV.

Methods: A cross-sectional, retrospective study was conducted in women undergoing lower limb venous mapping for varicose vein surgery. The following parameters were analyzed in GVs in which reflux was detected: segmental or diffuse reflux pattern; GV diameter and depth; and reflux in the SSV caused by the GV. 

Results: 340 of the 2368 women evaluated were included in the study because they had a GV, totaling 511 veins analyzed, 150 (29.4%) of which had reflux. The diameters of the 150 GVs with reflux ranged from 1.5 to 7.8 mm and their depth varied from 4 to 25 mm. Most GVs with reflux (91.3%) had a segmental reflux pattern. The majority (66%) of refluxing GVs drained reflux into the popliteal vein through the saphenopopliteal junction, while reflux was transferred to the SSV in 34 veins (22.7%), and was drained by a tributary vein in the thigh in 15 veins (11.3%).

Conclusions: Approximately one-third of the studied GVs had reflux, mostly segmental, mean caliber was 2.7 mm, and mean depth was 11 mm. Reflux in the SSV originating from the GV was detected in 22% of the evaluated veins.
