Objective: To explore the treatment of type II endoleak (TEE) after the endovascular aneurysm repair (EVAR) of abdominal aortic aneurysm (AAA).

Methods: From January 2009 to July 2011, 10 patients with type II endoleak after AAA EVAR were recruited. Different treatment methods were employed for the criminal arteries, including transcatheter embolization with coils, percutaneous sac puncture, intrasac injection of fibrin glue and outcome follow-up.

Results: Among them, 9 patients underwent treatment and 8 received a mean follow-up of (2.4 ± 1.6) months. The mean secondary time was (62 ± 39) months. The criminal arteries were inferior mesenteric artery (n = 3), internal iliac artery (IA) (n = 1), IA with lumbar artery (n = 3) and lumbar artery (n = 3). Two patients died from cardiovascular and cerebrovascular events during the follow-up. The primary technical success was 44%, retreat rate 33% and clinical success rate 89%.

Conclusions: Type II endoleak has a relatively benign course. In the absence of sac expansion, it can be followed for a long period of time without the needs for intervention. Treatment is necessary when it persists beyond 12 months or when there is a significant increase in aneurysm sac diameter.
