Methods: Data were prospectively collected in a unicenter observational study (tertiary center of [endo-] vascular surgery) and retrospectively evaluated in patients who had undergone elective EVAR of AAA. Vascular (lumbar arteries (LA) and inferior mesenteric artery, aneurysm) and general patient (habits, medication, basic diseases) as well as procedural characteristics, were analyzed for their association with the development of endoleak type II. Pre and postinterventional computed tomography (CT) scans were evaluated for aneurysm anatomy, in particular, postinterventional growth or shrinkage as well detection of an endoleak of each type. Results: The study cohort included 82 patients (mean age, 72 (52-87) years; 77 men, 93.9 %) throughout 36 months. The median follow-up period was 29.5 months (range, 1-57). Overall, 51 endoleaks type II (62.2 %) were identified at any time during the postinterventional follow-up period. In the Cox regression, AAA length was the only significant predictor (P = 0.024; hazard ratio (HR), 1.07; 95 % confidence interval (CI), 1.01-1.14). Thirteen patients (15.8 %) underwent at least one secondary intervention. Aneurysm growth was observed in four patients because of an endoleak type II (4.9 %). No AAA rupture occurred in association with an isolated endoleak type II. Conclusion: The preoperative AAA length (correlating with the number of LA) can be considered a risk factor for postinterventional occurrence of endoleak type II prompting to greater attention and possible preemptive therapy.
