CPT® Code 34501

The procedure described by CPT® Code 34501 refers to a valvuloplasty performed on the femoral vein. This surgical intervention is primarily indicated for patients suffering from valvular incompetence, a condition where the valves in the veins do not close properly, leading to blood pooling and potential complications such as venous ulceration. During the procedure, the surgeon exposes the femoral vein and carefully dissects the adventitia, which is the outer layer of the vein, to locate the valve commissures—the points where the valve leaflets meet. A marking suture is then placed at the commissure of the faulty valve to guide the subsequent surgical steps. A longitudinal incision is made in the vein, starting from a point distal (further away from the heart) to the valve and extending through the marking suture to a point proximal (closer to the heart) to the valve. This incision allows the vein to be laid open, and retention sutures are placed in the four corners of the incision to provide traction and maintain clear visibility of the valve during the repair process. The incompetent valve leaflets are then repaired to restore their normal cup-like configuration, which is essential for proper venous function. Finally, the femoral vein is closed, and the overlying tissues are repaired with sutures, completing the procedure and aiming to restore normal venous flow and alleviate symptoms associated with valvular incompetence.
