Title: The Influence of Preoperative Aneurysmal Thrombus Quantity and Distribution on the Development of Type II Endoleaks with Aneurysm Sac Enlargement After EVAR of AAA

Abstract

PurposeTo determine the influence of preoperative aneurysmal thrombus quantity and distribution on the development of type II endoleak with aneurysm sac enlargement after endovascular aneurysm repair (EVAR).Materials and MethodsWe retrospectively analyzed the pre- and postoperatively performed CT scans of 118 patients who had follow-up imaging for at least 1 year after EVAR available. We assessed preoperative thrombus perimeter (T{sub Peri}), diameter (T{sub Dia}), cross-sectional area (T{sub CSA}), and volume (T{sub Vol}). The preoperative thrombus distribution was classified into no thrombus, semilunar-shaped (anterior, right side, left side, posterior) thrombus, and circumferential type thrombus. The number of preoperative patent aortic side branches (ASB) was identified. Endpoint was type II endoleak with aneurysm volume (A{sub Vol}) increase of ≥5 % during follow-up.ResultsDuring follow-up (2 years, range 1–9 years), 17 patients with type II endoleak had significant A{sub Vol} increase. Less preoperative T{sub Peri}, T{sub Dia}, T{sub CSA}, and T{sub Vol} were associated with A{sub Vol} increase. A circumferential thrombus distribution significantly protected against aneurysm enlargement (p = 0.028). The variables with the strongest significance for A{sub Vol} increase were preoperative T{sub Vol}/A{sub Vol} ratio (OR 0.95; p = 0.037) and number of patent ASB (OR 3.52; p < 0.001).ConclusionA low preoperative T{sub Vol}/A{sub Vol} ratio and a high number of patent ASB weremore » associated with aneurysm sac enlargement after EVAR.« less
