Dynamic Computed Tomography Angiography as Imaging Method for Endoleak Classification after Endovascular Aneurysm Repair: A Case Series and Systematic Review of the Literature
Abstract:Introduction: This study evaluated our experience with dynamic computed tomography angiography (dCTA) as a diagnostic tool after endovascular aortic aneurysm repair (EVAR) with respect to the endoleak classification and the available literature. Methods: We reviewed all patients who underwent dCTA because of suspected endoleaks after the EVAR and classified the endoleaks in these patients based on standard CTA (sCTA) and dCTA. We systematically reviewed all available publications that investigated the diagnost… Show more
“…Endoleaks may be hard to determine even with the use of multiphase CTA. The research group of Fioole showed that dynamic CTA is of added value regarding the detection and classification of slow-flow endoleaks, and especially of type 2 endoleaks which usually originate from backbleeding lumbar arteries [3]. Improvement of the endoleak classification also allows the endovascular specialist to make targeted reinterventions.…”
