The common treatment approach for infrarenal AAA is?

The common treatment approach for an infrarenal abdominal aortic aneurysm (AAA) typically involves the placement of a stent graft or surgical intervention. This is because infrarenal AAAs, which occur just below the renal arteries, often require a direct approach to repair the weakened area of the aorta to prevent rupture.

Stent graft placement is a minimally invasive option that allows for the reinforcement of the aorta by placing a graft within the aneurysm to exclude it from circulation, thereby reducing the risk of rupture. This procedure is often preferred due to shorter recovery times and less discomfort for the patient compared to open surgical repair.

Open surgery, on the other hand, involves directly accessing the aneurysm through an abdominal incision, removing or reinforcing the affected section of the aorta, and is typically utilized in cases where endovascular repair is not feasible due to the anatomy or other patient-specific factors.

Both methods aim to prevent serious complications such as aortic rupture, which can be life-threatening. Thus, placement of a stent graft or surgical intervention is established as the standard treatment approach for infrarenal AAA.
