Resumo

OBJETIVO: Determinar a prevalência de refluxo venoso na veia safena parva em membros inferiores com varizes primárias não complicadas pelo eco-Doppler colorido. MÉTODO: No período de 18 meses, 1.953 pacientes foram submetidos ao eco-Doppler colorido de membros inferiores por doença venosa. Destes, 1.631 com varizes primárias não complicadas foram selecionados para esta análise, sendo que 1.383 eram do sexo feminino (84,79%) e 248 (15,21%) do sexo masculino. A média de idade dos pacientes foi de 42,89 (± 0,48) anos, variando de 13 a 85 anos. Dos 1.631 pacientes, 1.323 foram submetidos a exame bilateral e 308 a exame unilateral, totalizando 2.954 membros inferiores com varizes primárias não complicadas avaliados. Desse total, 1.461 eram membros inferiores direitos e 1.493, esquerdos. Todos os exames foram realizados seguindo o mesmo protocolo. RESULTADO: Dos 2.954 membros inferiores avaliados, 372 (12,59%) apresentaram refluxo em veia safena parva. A prevalência nos homens foi de 14,08% e, nas mulheres, de 12,35%. O refluxo da safena parva foi maior no membro inferior esquerdo (13.13%) do que no direito (12,05%). A prevalência do refluxo foi significativamente maior nos pacientes acima de 60 anos. CONCLUSÃO: O refluxo da veia safena parva é relativamente comum, e sua pesquisa deve ser sempre realizada em pacientes com varizes primárias de membros inferiores.

Abstract

OBJECTIVE: To determine the prevalence of small saphenous vein reflux (SSVR) in patients with uncomplicated varicose veins, using color-flow Doppler ultrasonography. METHOD: Over an 18-month period, a total of 1,953 patients underwent color-flow Doppler ultrasonography for evaluation of venous disease. Out of the total, 1,631 patients with primary uncomplicated varicose veins were selected for this study: 1,383 (84.79%) patients were female and 248 (15.21%) were male. Mean age was 42.9 (± 0.48) years, ranging from 13 to 85 years. Of the 1,631 patients, 1,323 underwent bilateral examination and 308 unilateral examination, for a total of 2,954 lower limbs with primary uncomplicated varicose veins studied. The number of right lower limbs studied was 1,461 and the number of left lower limbs was 1,493. All exams were carried out using the same protocol. RESULT: Out of the total number of 2,954 limbs, SSVR was detected 372 (12.59%) limbs. Prevalence of SSVR in males was 14.08% and in females was 12.35%. SSVR was detected in the right lower limb in 12.05% and in left lower limb in 13.13% of the cases. SSVR was significantly more common in patients older than 60 years. CONCLUSION: SSVR is relatively common and its presence should always be investigated in patients with primary lower limb varicose veins.
