Abdominal Aortic Aneurysm

January 19, 2020 at 3:43 pm

Currently, there are two main options for repair of abdominal aortic aneurysms (AAA): open repair and endovascular repair. Since the early 2000s, Endovascular Repair of Aneurysm (EVAR) has become the mainstay for treatment of AAAs. As opposed to open repair, EVAR is a minimally invasive procedure that involves placement of a large covered stent (stent-graft) via the large arteries in the groins.

The advantages of EVAR over open repair are vast and include significantly less pain, length of hospital stay, and blood loss. Since its inception, stent-graft technology has markedly improved. The first endovascular repairs in the early 1990s were performed with insertion of Dacron (polyester fiber) fixed stainless-steel stents. Since that time, advances in technology and changes in prosthetic material have allowed for development of stent-grafts that are more durable, fatigue resistant, conformable, and easily-deployed.
