Resumo

As veias linfonodais fazem parte de uma rede venosa no triângulo de Scarpa, que liga em vários pontos o sistema venoso superficial às veias profundas, e podem tanto ser causa de incompetência do sistema venoso superficial quanto estar envolvidas na recorrência pós-safenectomia. Na rotina diária dos exames de Doppler venoso de membros inferiores, temos notado de maneira cada vez mais freqüente a associação das veias linfonodais com varizes primárias e recorrentes. A adequada caracterização dessas veias pode ajudar na compreensão do mecanismo fisiopatológico do aparecimento das varizes e permitir um controle e tratamento mais dirigidos. Este artigo lança luz sobre os aspectos anatômicos e fisiológicos das veias linfonodais, objetivando chamar a atenção dos profissionais envolvidos no diagnóstico de doenças venosas dos membros inferiores para uma causa pouco difundida de varizes.

Abstract

Lymph node veins are part of a venous network in Scarpa"s triangle, communicating in many points the superficial venous system and the deep veins, and may either be the cause of incompetence of the superficial venous system, or be involved in recurrent varicose veins after saphenous vein stripping. In the daily routine of venous Doppler examination of the lower extremities, an increasingly frequent association of lymph node veins with primary and/or recurrent varicose veins has been noticed. Appropriate characterization of these veins may help to understand the pathophysiological mechanism of varicose vein appearance and provide a more focused approach to follow-up and treatment. This article sheds some light on the anatomical and physiological aspects of lymph node veins, drawing the attention of professionals involved in the diagnosis of venous disorders of the lower extremities to a little-known cause of varicose veins.
