[Variations of venous lesions of lower extremities associated with varicose veins]

374 varicose extremities in 238 patients were examined. In 344 (92%) out of 374 extremities valvular incompetence and dilatation of the basal trunk of the great saphenous vein over its length were found. In 212 (56.7%) extremities dilatation of the first median anastomosis between the great and small saphenous veins was found. The upper medial inflow in the leg gets injuried in 36.1% of cases, and the superficial tibial vein in 28%. Lateral varicosity occurred in 0.5% of cases. Injuries to the lateral branches without dilatation of basal trunk constituted 5.6%. There were no cases of dilatation of femoro-popliteal vein.
