Endoleaks: Current Concepts And Treatments - A Narrative Review, Zia Ur Rehman

Department of Surgery

Endoleaks are the most common complications following endovascular aneurysm repair. Depending upon their origin, there are five types of endoleaks, types I-V, which can also be classified as direct and indirect endoleaks. Direct endoleaks (type I and III) have higher risk of aneurysm rupture due to rapid sac expansion, and require immediate correction. Indirect endoleaks ( type II, IV and V) have a relatively benign course compared to direct endoleaks. Most of them resolve with time and very few need interventions upon sac enlargement. Type V endotension is a special situation where there is sac enlargement despite no demonstrable endoleak. …

Natural History Of Gutter-Related Type Ia Endoleaks After Snorkel/Chimney Endovascular Aneurysm Repair., Brant W Ullery, Kenneth Tran, Nathan K Itoga, Ronald L Dalman, Jason T Lee

Articles, Abstracts, and Reports

OBJECTIVE: Alternative endovascular strategies using parallel or snorkel/chimney (chimney endovascular aneurysm repair [ch-EVAR]) techniques have been developed to address the lack of widespread availability and manufacturing limitations with branched/fenestrated aortic devices for the treatment of complex abdominal aortic aneurysms. Despite high technical success and midterm patency of snorkel stent configurations, concerns remain regarding the perceived increased incidence of early gutter-related type Ia endoleaks. We aimed to evaluate the incidence and natural history of gutter-related type Ia endoleaks following ch-EVAR.

METHODS: Review of medical records and available imaging studies, including completion angiography and serial computed tomographic angiography, was performed for all …
