The Achilles' heel of endovascular aneurysm repair (EVAR) is still the higher reintervention rate in comparison to open aneurysm repair as shown in the well-known large randomized controlled studies. While problems of the proximal landing zone are widely discussed in the literature, the distal landing zone draws less attention. The literature shows significant dilatation of the common iliac artery (CIA) after EVAR, especially if the iliac arteries were aneurysmal initially, as well as an incidence of type Ib endoleak up to 17% in aortoiliac aneurysms. This implies the need for continued radiological surveillance as well as good treatment options for the needed reinterventions.
