Caudal movement of the proximal aspect of an aortic endograft is a significant late failure of endovascular aneurysm repair (EVAR). This endograft migration can cause type Ia endoleak and enlargement and rupture of an abdominal aortic aneurysm (AAA). Thus, surveillance…
Postoperative surveillance is an integral part of the overall treatment strategy after endovascular aortic repair, and failure of surveillance can be considered tantamount to no treatment at all. Indeed, suspected noncompliance to follow-up during preoperative evaluation of a potential endovascular…
Neurologic complications after aortic surgery can range from minor irritants to life-threatening problems. It is important to recognize that the majority, but certainly not all, can be avoided by careful preoperative planning and meticulous intraoperative technique. Spinal Cord Injury The…
Death, myocardial infarction, and bleeding are the complications most discussed with patients before aortic surgery, but kidney failure and intestinal injuries can be the most devastating and lead to a dramatically higher morbidity and mortality. This chapter reviews the etiology…
Scope of the Problem Historical reports documented acute limb ischemia in up to 25% of patients undergoing abdominal aortic surgery. With refinement of operative technique and the use of local and systemic anticoagulation, the incidence of this complication has decreased…
Endovascular abdominal aortic aneurysm repair (EVAR) is predicated on complete exclusion of the aneurysm from the arterial circulation. An endoleak, or continued arterial perfusion of the aneurysm sac after endovascular treatment, can compromise the effectiveness of EVAR. There are five…
Endovascular aneurysm repair (EVAR) has proved to be safe and effective for the primary treatment of aortic aneurysms. However, endoleaks, endotension, migration, and stent fracture can lead to aneurysm growth and rupture if not treated in a timely fashion. Although…

Endovascular aneurysm repair (EVAR) offers significant benefits to many patients, yet the applicability of EVAR has been challenged in patients with unfavorable proximal necks or aneurysmal involvement of the iliac arteries. The latter situation occurs in 12% to 40% of…
An important requirement for endovascular aortic or iliac aneurysm repair is the presence of an adequate distal landing zone in the common iliac artery. Aneurysmal aortas are associated with dilated common iliac arteries in about 20% of patients, making patients…
