What type of stent may be used in the repair of AAA?

The correct choice involves the use of endovascular aortic stent grafts for the repair of abdominal aortic aneurysms (AAAs). Endovascular stent grafts are specifically designed to provide a minimally invasive method for repairing aneurysms. These devices consist of a stent that is covered with a graft material, allowing it to reinforce and support the wall of the aorta while redirecting blood flow away from the aneurysm sac.

The advantages of using endovascular aortic stent grafts include a shorter recovery time, reduced risk of complications compared to open surgery, and the ability to perform the procedure using local anesthesia with imaging guidance. This approach has become the preferred treatment option for many patients who are anatomically suitable.

In contrast, while open surgical stents, arterial grafts, and standard balloon stents may be used in various vascular interventions, they are not specifically designed for the management of AAAs. Open surgical stents typically require a major surgical procedure, which can result in higher morbidity and longer recovery times. Arterial grafts are used for bypass or replacement of segments of the artery but do not function the same way as stent grafts in the context of AAAs. Standard balloon stents are primarily intended for
