Objective The most common complication after endovascular aortic repair (EVAR) is a type II endoleak. Although the majority of type II endoleaks is considered benign, the exact natural course remains unclear. Therefore, the best way to manage these endoleaks is still under debate. Our study aimed to evaluate the natural course, long term-survival, number of reinterventions and complications in patients with a type II endoleak, that underwent an EVAR in the University Medical Center Groningen (UMCG). Methods From January 2000 till January 2014, 616 EVARs were performed. Baseline characteristics, procedural information, abdominal aortic aneurysm (AAA) details and follow-up information were collected from the electronic patient files. Four groups were analysed. Patients without any endoleak to patients with an isolated type II endoleak. The isolated type II endoleaks were subdivided in early (≤30 days after EVAR) and late (>30 days after EVAR) type II endoleaks. Baseline characteristics, as well as change in diameter, complications, reinterventions and survival were analysed. Results The overall incidence of isolated type II endoleaks was 24.4%. The majority were diagnosed in the early period (78.5%). Cardiac failure was found to be more prevalent in patients without any endoleak. Patients with an isolated type II endoleak were found to have higher reintervention rates and more sac enlargement during long term follow-up. The occurrence of isolated type II endoleaks did not impact long term-survival, compared to those without any endoleak. The late type II endoleak group showed a better survival compared to those by whom a type II endoleak was detected in the early time period. Conclusion Patients with a type II endoleak have a higher incidence of sac expansion and a higher reintervention rate compared to those without any endoleak. Survival does not differ between them. Patients with a late type II endoleak have a better survival compared to patients with an early type II endoleak.
