Operation Definition
Putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part
Procedure Overview
Replacement procedures in the lower arteries involve taking out a diseased or damaged arterial segment and putting in synthetic graft material or biological tissue to physically stand in for that piece of vessel. This is distinct from simply patching or reinforcing an artery, since the native segment is functionally substituted rather than preserved and bolstered.
A classic example is an aortobifemoral or femoral-popliteal graft placed after removing a severely diseased, occluded, or aneurysmal segment of artery, using a synthetic conduit such as Dacron or PTFE, or in some cases a harvested vein used as a full segmental replacement. Patients typically arrive at this procedure after conservative management or angioplasty has failed, or when an aneurysm poses a rupture risk that mandates excising the weakened wall.
Anatomy & Axis Detail
Popliteal Artery, Right
The right popliteal artery runs behind the knee, continuing the femoral artery into the lower leg before dividing into the tibial and peroneal branches, and its deep location amid tendons and the popliteal fossa makes it vulnerable to both atherosclerotic disease and blunt or penetrating trauma, including knee dislocation injuries. Because this segment has limited collateral circulation, occlusion or aneurysmal degeneration here carries a high risk of acute limb-threatening ischemia, often prompting more urgent surgical intervention than disease in more proximal arteries. Replacement typically involves excising the diseased or injured arterial segment and bridging the gap with an autologous vein graft, which tends to perform better than synthetic material in this below-knee position due to the flexion stresses the joint imposes on the graft.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Device: Synthetic Substitute
Synthetic Substitute designates a device made from manufactured, non-biologic material, such as mesh or prosthetic components, used to replace or augment a body part. It is distinguished from the two tissue substitute categories by its artificial composition, which carries different considerations for integration and long-term durability than biologic grafts.
Coding & Documentation
The operative report must clearly establish that a segment of native artery was excised or its function replaced, and that a graft or biological material took its place, distinguishing this from Bypass, where the diseased segment is left in place and a new route is constructed around it. Coders should identify the specific arterial body part value replaced and the device value representing the graft material, whether autologous, nonautologous, or synthetic.
A common error is coding a bypass graft as a Replacement when the original artery segment was left intact and simply routed around; another is failing to capture the correct device value when a combination of graft materials was used in a single reconstruction.
