The association between perioperative embolization of hypogastric arteries and type II endoleaks after endovascular aortic aneurysm repair

Type II endoleaks (T2ELs) are the most common type of endoleaks after endovascular abdominal aortic aneurysm repair (EVAR). The iliolumbar artery arising from the hypogastric artery is often a major source of T2ELs, and transarterial embolization of the iliolumbar artery via the hypogastric artery is sometimes performed to interrupt sac expansion during follow-up. Considering the equivocal results regarding an association between hypogastric embolization and T2ELs in previous studies, this topic has re-emerged after the advent of iliac branch devices.
