CPT® Code 35884

The procedure described by CPT® Code 35884 involves the surgical revision of a femoral anastomosis that utilizes a synthetic arterial bypass graft. This operation is performed through an open approach, which means that the surgeon makes a direct incision in the groin area to access the previously placed arterial bypass graft. The primary purpose of this procedure is to address issues such as stenosis, which is a narrowing of the graft that can compromise its function and threaten the patency, or openness, of the graft. The bypass graft itself is a conduit that redirects blood flow from one artery to another, often used in cases where there are blockages or diseases affecting the blood vessels, such as those leading to the aorta, iliac, or popliteal arteries. During the revision, the surgeon carefully dissects the tissue to reach the anastomosis site, where the graft connects to the femoral artery. The integrity of this connection is assessed for any leaks or other complications. Once the problematic area is identified, clamps are applied to control blood flow, and the anastomosis site is incised to allow for further evaluation and repair. If a stenotic segment or other issues are found, this portion of the graft is excised. The repair is then performed using an autogenous vein patch graft, which is a section of vein harvested from the patient, ensuring that the graft is restored to a functional state. The new patch is meticulously sutured into place, and the anastomosis is reconnected to the femoral artery. After confirming the viability of the graft and ensuring that there are no leaks, the clamps are removed, and the surgical site is closed. This procedure is critical for maintaining adequate blood flow and preventing complications associated with graft failure.
