Placement of proximal or distal extension prosthesis for endovascular repair of infrarenal abdominal aortic or iliac aneurysm, false aneurysm, or dissection; initial vessel

The procedure described by CPT® Code 34825 involves the placement of a proximal or distal extension prosthesis specifically for the endovascular repair of an infrarenal abdominal aortic or iliac aneurysm, false aneurysm, or dissection. In simpler terms, this procedure is performed when the main endograft components used to repair the aorta or iliac artery are determined to be insufficient in length. This insufficiency is often identified during the initial endograft repair as an endoleak, which is a condition where blood leaks from the main graft into the surrounding area. The extension prosthesis serves as an additional component that extends the reach of the existing graft to effectively seal off the endoleak. The placement of the extension prosthesis can occur during the same surgical session as the initial repair or may be performed in a subsequent session if the endoleak is detected postoperatively. The procedure involves advancing a sheath that contains the extension prosthesis over a guide wire to the site of the endoleak. Once positioned, fluoroscopy is utilized to confirm the correct placement of the prosthesis. Following confirmation, the extension prosthesis is deployed and secured in place using a balloon catheter. To ensure that the endoleak is adequately sealed, contrast material is injected, allowing for visualization of the repair. This procedure is critical for maintaining the integrity of the vascular repair and preventing complications associated with aneurysms or dissections.
