Our results suggest that endovascular treatment of infrarenal abdominal aortic aneurysms is technically feasible and can effectively exclude abdominal aortic aneurysms from the circulation. With further refinement, endoluminal repair may emerge as an interventional strategy to treat infrarenal aortic aneurysms, especially in patients at high surgical risk.

The surgical repair of an atrial septal defect in patients over 40 years of age, as compared with medical therapy, increases long-term survival and limits the deterioration of function due to heart failure. However, surgically treated patients should be followed closely for the onset of atrial arrhythmias so as to reduce the risk of thromboembolic complications.

Exclusion of AAA from circulation was feasible, safe, and clinically effective with the new stent-graft.

(1) The results suggest that most complications are due to a continuation of the disease process leading to loosening of the prosthesis. (2) Explantation of the prosthesis and surgical repair is feasible but bears additional risks. (3) Because the onset of reperfusion of the excluded aneurysm cannot be predicted, all patients with infrarenal aortic stent-grafts require frequent computer tomographic follow-up. (4) Finally, the results call for further improvements in the design of the stent-graft.
