Abstract Background The accurate identification of reflux points in the study of primary varicose veins of the lower limbs is important in the therapeutic approach of these patients. Objective To evaluate the association between insufficiency of the anterior perforator vein of the knee and great saphenous vein insufficiency in patients with primary varicose veins of the lower limbs. Methods The study included 886 patients, corresponding to 1,772 lower limbs, in patients older than 18, of both sexes, undergoing superficial venous […]

Summary Introduction Venous anatomy may present significant variability, with a wide incidence of venous tributaries, duplicate or accessory veins related to saphenous veins. The recognition and identification of these variations are important in the therapeutic management of these patients, and vascular ultrasonography is the method of choice in the evaluation of the peripheral venous system. Objectives To evaluate the association between anatomic variance of the great saphenous vein (VSM) and venous insufficiency of the lower limbs in patients with primary […]
