Official Description

Open repair of infrarenal aortic aneurysm or dissection, plus repair of associated arterial trauma, following unsuccessful endovascular repair; aorto-bi-iliac prosthesis

Common Language Description

The CPT® Code 34831 refers to the open surgical repair of an infrarenal aortic aneurysm or dissection, which is a serious condition characterized by the abnormal dilation or tearing of the aorta located below the renal arteries. This procedure is specifically indicated for cases where previous endovascular repair attempts have failed. Such failures may result in complications like endoleaks, which are leaks of blood into the aneurysm sac, dissection, which is a tear in the aortic wall, or occlusion of major aortic branches that can impede blood flow to vital organs. The surgical approach involves making an abdominal incision to access the aorta and the iliac or femoral vessels, allowing the surgeon to directly visualize and repair the affected areas. The procedure also includes the repair of any associated arterial trauma that may have occurred during the initial endovascular repair attempt. The use of an aorto-bi-iliac prosthesis is a critical component of this repair, as it provides a stable conduit for blood flow following the removal of the aneurysm or dissection. This comprehensive approach aims to restore normal vascular function and prevent further complications associated with aortic aneurysms or dissections.
