Resumo

ResumoContextoHá diferenças individuais no diâmetro da veia safena magna (VSM) em membros normais e doentes; sendo possível a identificação dessas alterações pelo ecocolor Doppler.ObjetivoAvaliar a associação da aplasia segmentar da VSM com a presença de varizes e/ou insuficiência da mesma em membros inferiores, usando o ecocolor Doppler em pacientes com clínica de doença venosa crônica (DVC).Métodos1.408 pacientes com queixas compatíveis de DVC de membros inferiores, sendo 1.286 do sexo feminino, com idade entre 17 e 85 anos, examinados com ecocolor Doppler. Foram incluídos aqueles com classificação CEAP clínica C0 a C4. Pela avaliação clínica, a amostra foi distribuída em grupo A, pacientes com varizes, e grupo B, aqueles sem varizes. O ecocolor Doppler determinou se havia aplasia da VSM pela análise do seu trajeto no compartimento safeno e presença de veias varicosas nos diferentes sítios. Para estatística, foram considerados os testes Qui-quadrado ou Exato de Fisher e uma análise de resíduos em tabelas, com nível de significância de 5%.ResultadosNo grupo A houve 479 (83,9%) de VSM insuficientes, 169 (38,2%) com aplasia e 71 (80,7%) com insuficiência e aplasia associadas. No grupo B, houve 92 (16,1%) de VSM insuficientes, 273 (61,8%) com aplasia e 17 (19,3%) com insuficiência e aplasia associadas.ConclusãoA aplasia segmentar da VSM ocorre mais em membros inferiores que não apresentam varizes e/ou insuficiência da mesma, mas considerando-se a presença da associação de aplasia e insuficiência, houve maior incidência no grupo de membros que apresentavam varizes.

Abstract

AbstractBackgroundThere are individual differences in the diameter of the great saphenous vein (GSV) in both normal and non-functional limbs and it is possible to identify these differences using color Doppler ultrasonography.ObjectivesTo assess the association between segmental GSV aplasia and the presence of varicose veins and/or GSV insufficiency in lower limbs using color Doppler ultrasonography, in patients with chronic venous disease (CVD).MethodsA total of 1,408 patients with complaints compatible with CVD of lower limbs were examined using color Doppler ultrasonography. The age range of the sample was from 17 to 85 and 1,286 of the patients were female. People with clinical classifications (CEAP) ranging from C0 to C4 were included. On the basis of clinical examination, the sample was subdivided as follows: group A patients had varicose veins and group B patients were free from varicose veins. Color Doppler ultrasonography was used to determine whether there was GSV aplasia, by analysis of its route into the saphenous compartment, and the presence of varicose veins in different sites. Statistical analysis was conducted using the chi-square test or Fisher’s exact tests followed by an analysis of residuals in tables, with a 5% significance level.ResultsIn group A, there were 479 (83.9%) patients with GSV insufficiency, 169 (38.2%) with aplasia and 71 (80.7%) with both insufficiency and aplasia. In group B, there were 92 (16.1%) patients with GSV insufficiency, 273 (61.8%) with aplasia and 17 (19.3%) with both insufficiency and aplasia.ConclusionSegmental GSV aplasia was more common in lower limbs with no varicose veins and/or insufficiency, but there was a higher incidence of patients with both aplasia and insufficiency in the group with varicose veins.
