Using advanced imaging methods, the surgeon guides the delivery catheter carrying the stent graft to the area of the abdominal aortic aneurysm. No failed insertions and no conversions to open surgery occurred. Abdominal aortic aneurysm (AAA) repair is surgery to fix an aneurysm in your abdominal aorta. Endovascular repair, which is less invasive than open surgery, involves excluding (sealing off) the aneurysm by placing an endovascular graft inside of the diseased aorta, making a new path for the blood to flow. This is called an aneurysm. An endovascular stent graft is a synthetic fabric tube (graft) supported by a metal structure (stent). Treatments & Therapies Symptoms of an aortic aneurysm depend on where the aneurysm is located within the body. One patient had acute aneurysm dilatation and rupture caused by a type II endoleak through the inferior mesenteric artery 6 months after stent graft implantation. Distally, there must be disease-free zones in the iliac arteries to ensure good leg perfusion and at least one of the femoral arteries should be >8 mm in i… It explains the benefits and risks of the procedure, as well as what you can expect when you come to … Multicenter trial of the PowerLink bifurcated system for endovascular aortic aneurysm repair.
