Abstract

One of the major problems of treating aortic aneurysms has been the multifocal nature of atheroclerotic disease. Co-existing cardiovascular disease in the majority of patients together with chronic obstructive airways disease, renal impairment and hostile abdoment in some, has resulted in 1/3 of patients presenting with aortic aneurysms being regarded as high risk and unfit for open repair. Endovascular repair of aortic aneurysm therefore has much to recommend it since it avoids the need for laparatomy, cross clamping of the aorta and the obligatory blood loss associated with opening of the sac. Between May 1992 and March 2003 we have used the endovascular method to repair abdominal aortic aneurysms (AAA) in 583 patients. Successful repair was achieved in 563 patients (96%). The remaining 20 patients required primary conversion to open repair at the original operation. The 30-day perioperative mortality rate was 13 of 583 (2.2%). In this paper we summarise a number of studies that we have undertaken, comparing endovascular with alternative treatment methods and comparing various types of endovascular prostheses. In addition we report the long-term outcome of endovascular AAA repair as it relates to morphological changes in the proximal neck out to 9 years from operation. We conclude that despite the continuing small incidence of device failure, endovascular is the preferred method of AAA repair in the multifocal atherosclerotic patient. This view is based on the low perioperative mortality, superior survival compared with open repair and our experience of long-term stability in the proximal neck in the majority of patients.
