CPT® Code 33895

Endovascular stent repair of coarctation of the ascending, transverse, or descending thoracic or abdominal aorta, involving stent placement; not crossing major side branches

The procedure described by CPT® Code 33895 involves the endovascular stent repair of coarctation, which refers to a narrowing of the aorta, specifically in the ascending, transverse, or descending thoracic or abdominal regions. This condition is often congenital, meaning it is present at birth, but may not manifest until later in life. In some instances, aortic coarctation can arise due to trauma, severe atherosclerosis, or inflammation. The endovascular approach utilizes a catheter, which is a thin, flexible tube, to navigate through the vascular system. The catheter is inserted into the iliac artery via a small access point in the groin and is guided under imaging techniques into the aorta, precisely positioning it at the site of the narrowing. Once in place, a balloon at the tip of the catheter is inflated to widen the constricted area of the aorta. Following this, a mesh stent is deployed to keep the artery open, ensuring that blood can flow freely. This minimally invasive technique is preferred over traditional open surgery due to its reduced recovery time and lower risk of complications. However, there remains a possibility that the coarctation may recur, necessitating further intervention. It is important to note that untreated aortic coarctation can lead to serious health issues, including brain aneurysms, aortic dilation or rupture, heart failure, stroke, and early onset of coronary artery disease.
