Endoleak after endovascular repair of abdominal aortic aneurysm

Abstract

Type I endoleaks represent a persistent risk of aneurysm rupture and should be treated promptly by endovascular means. Type II leaks are less dangerous and more difficult to treat, but coil embolization of feeding arteries may be warranted when leakage is associated with aneurysm enlargement.

Endovascular Management of Thoracic Dissections

“…69 Extrapolating from stent-graft treatment of abdominal aortic aneurysm, type I endoleaks require immediate repair, usually involving placement of an additional stent extension, and type II endoleaks may be monitored. 90 The consequence of endoleaks in stent-graft management of aortic dissection is not well known, although such leaks are associated with persistent flow in the false lumen and may predispose to complications of false-lumen expansion or rupture. 31 Other reported complications include stent-graft migration, stent-graft torsion, aortoesophageal fistula, and mobile thrombus within the stent-graft lumen.…”

Endovascular Repair of Abdominal and Thoracic Aortic Aneurysms

“…95 Treatment options include transcatheter coil or glue embolization, balloon angioplasty, placement of endovascular graft extensions, and open repair. 96,97 Despite the hostile hemodynamic conditions of the thoracic aorta, the anticipated complications of device migration and kinking have occurred infrequently and have been observed primarily with homemade devices and those with unsupported mid-graft segments. 70 For both homemade and commercial endografts, however, questions about device durability and stability over the long term remain unanswered.…”

Incidence and Predictors of Clinical Failures Following Catheter-Based Treatment of Abdominal Aortic Aneurysms

“…This position may be challenged by some who believe that any demonstrated endoleak is a criteria of failure. Indeed, the clinical significance of endoleak remains uncertain and poorly understood (Chuter et al, 2001;Makaroun et al, 1999;Matsumura & Moore, 1998;Steinmetz et al, 2004;Timaran et al, 2005). Two factors indendently favored an increased incidence of endoleak in our series: advanced age and female gender.…”
