A venous closure catheter is disclosed for performing sclerotherapy which includes an elongated catheter body having opposed proximal and distal end portions, a fluid delivery lumen and a guidewire lumen. A plurality of discharge apertures are associated with the distal end portion of the catheter body and communicate with the fluid delivery lumen for delivering a sclerosing solution into the saphenous vein. A circumferential flange is positioned on an exterior surface of the catheter body proximal to the discharge apertures, which has a plurality of projections formed thereon for traumatizing the inner wall of the saphenous vein upon removal of the catheter body therefrom to promote closure of saphenous vein after sclerotherapy. A compression apparatus is disclosed for providing therapeutic pressure subsequent to sclerotherapy. The compression apparatus includes first and second wraps for providing compression of an upper leg, and the lower leg and foot, respectively.
