Aneurysm Repair Procedures

Aneurysm Repair Procedures

Vascular Institute of Chattanooga performs a range of aneurysm repair procedures tailored to treat patients’ medical needs. To learn about these procedures and what they entail, click each one below.

An abdominal aortic aneurysm is a common problem where the wall of a blood vessel weakens, and a balloon-like dilation called an aneurysm develops. This happens most often in the abdominal aorta, an essential blood vessel that supplies blood to your legs. The repair of the aneurysm can be lifesaving and be performed with an open surgical technique – removing the aneurysm, or an endovascular minimally invasive stent procedure. The majority of patients could qualify for the less invasive procedure after evaluation by your vascular surgeon.

Endovascular Aneurysm Repair (EVAR) is a minimally-invasive endovascular surgical procedure used to treat aneurysms of the aorta that begin below the renal arteries. Two small incisions are made in the groin exposing the femoral arteries. A graft is then inserted inside of the artery and positioned at the top and the bottom of the affected area of the aorta, allowing the blood flow to pass through removing the pressure from the weakened artery wall.

A popliteal aneurysm is an irregular bulge that happens in the artery behind the knee joint; this is categorized as a lower extremity aneurysm. This type of aneurysm, if small, is one that can be watched and monitored by your vascular surgeon. Ultrasound testing and regular office visits with a medication regimen may be prescribed to some patients. If the aneurysm is large or causing symptoms, an endovascular procedure can be performed with a special covered stent to treat the problem. This procedure is less invasive and can be performed in an outpatient facility.

Thoracic Endovascular Aneurysm Repair (TVAR) is an endovascular surgical procedure that involves the placement of an expandable stent graft within the thoracic aorta, within the chest, to treat the disease process. This procedure is most commonly used to treat aneurysms or dissections inside the thoracic aorta. This stent surgery occurs in the hospital setting and allows for the blood flow to be redirected to a new route, eliminating the bulge and pooling of blood in the aorta restoring circulation to the body.
