Natural History of Type Ia Gutter Endoleaks After Snorkel/Chimney EVAR

EVAR may reduce the risk of aneurysm rupture despite persisting type Ia endoleaks.

PURPOSE To determine the risk of aneurysm rupture in patients with persisting proximal type Ia endoleaks following endovascular aneurysm repair (EVAR) in comparison to the risk of rupture of untreated abdominal aortic aneurysms (AAA) of similar size. METHODS Among 400 patients who where treated with EVAR from 1996 to 2003 at a single center, 21 (5.3%) patients (13 men; mean age 78.0±5.0 years...

Endovascular Treatment of Endoleaks Following EVAR

Changes in suprarenal and infrarenal aortic angles after endovascular aneurysm repair

PURPOSE We investigated whether suprarenal and infrarenal aortic angles change after the endovascular aneurysm repair (EVAR) procedure and during follow-up, and investigated the correlation between infrarenal aortic angle after EVAR and type Ia endoleaks. METHODS Data collected on 70 EVAR procedures for a fusiform infrarenal aortic aneurysm performed between May 2006 and December 2012 were su...

EVAR: critical applied aortic morphology relevant to type-II endoleaks following device enhancement in patients with abdominal aortic aneurysms.

Endovascular repair (EVAR) of abdominal aortic aneurysms (AAA) is an established alternative option to conventional surgery for AAA, provided optimal anatomical morphology of the aneurysm sac, neck and outflow exists. In most documented series of EVAR, type-II endoleak occurrence is a universal procedural drawback. This is referred to as the Achilles heel of EVAR. This morphological study, addr...
