[Aneurysm of the internal saphenous vein: report of a case].

Venous aneurysms of the lower extremities are rare. They have been reported in both the deep and superficial vein system. Thromboembolism is more common in aneurysms involving the popliteal vein than those involving superficial veins. We report a case of primary aneurysm of the greater saphenous vein presenting as an inguinal hernia. Sonography has confirmed the venous dilatation. we review also the clinical and therapeutic findings of venous aneurysms of the lower extremities.
