Increased recognition of type II endoleaks using a modified intraoperative angiographic protocol: implications for intermittent endoleak and aneurysm expansion.

Retrograde arterial perfusion of the aneurysm sac (type II endoleak) may complicate endovascular abdominal aortic aneurysm (AAA) repair and may lead to AAA expansion and rupture. Aneurysm expansion may also occur in the absence of a demonstrable endoleak. Current intraoperative assessment techniques may underrepresent the incidence of type II endoleaks.

Endovascular treatment of failed prior abdominal aortic aneurysm repair.

Failure of endovascular or conventional abdominal aortic aneurysm (AAA) repair may occur as a result of attachment site endoleak (type I) or paraanastomotic aneurysm and pseudoaneurysm formation. This study examined the results of the use of secondary endovascular grafts for the treatment of failed prior infrarenal AAA repair procedures. Forty-seven patients were treated with endovascular grafts.

A multicenter experience with the Talent endovascular graft for the treatment of abdominal aortic aneurysms.

Objective: The Talent endovascular graft has been used in the treatment of abdominal aortic aneurysms (AAAs) in more than 13,000 patients worldwide. However, information regarding the results of its use has been limited. This report describes the experience with 368 patients with AAAs who underwent treatment at four medical centers as part of an investigator-sponsored investigational device exemption trial.

Failure of endovascular aortoaortic tube grafts: a plea for preferential use of bifurcated grafts.

Objective: Aortoaortic tube graft repair was the first technique used for the endovascular treatment of abdominal aortic aneurysms (AAAs). However, progressive changes in the morphology of the distal aortic neck may be responsible for procedural failure. This study examines the use of aortoaortic tube prostheses and analyzes the factors that contributed to their failure and the methods used for their subsequent repair.
