ABSTRACT
All patients who underwent endovascular aortic repair (EVAR) need a thorough follow-up, at least yearly. Contrast-enhanced ultrasound and computed tomography angiography (CTA) are the most important modalities for detection of endoleaks, whereby CTA allows better differentiation of endoleak type. High pressure endoleaks (type I and III) are an absolute indication for treatment if they do not resolve spontaneously in the short term. Type II endoleaks are mostly benign and may be routinely controlled if there is no progression of the aneurysm. Type II endoleaks associated with aneurysm progression may be treated with embolization; however, whether they must be treated is a matter of discussion. Nonetheless, a type II endoleak must be treated when progression shortens the aneurysm neck and the threat of a type I endoleak is at hand. Type I endoleaks are the main limitation of stent grafts. An adequate proximal landing zone is the best prevention for type I endoleaks, even if fenestrated stent grafts have to be used. Various fixation devices for short necks are currently under investigation.
