A 78-year-old male had undergone endovascular aortic aneurysm repair (EVAR) 7 years prior to presentation. Although the sac was stable 6 months ago, the patient presented with shock at arrival, and CT showed aortic rupture with rapid expansion due to type Ib endoleak caused by iliac neck dilatation (IND). The aneurysm sac was excluded using an endovascular strategy. Bell-bottom iliac limbs can cause IND associated with type Ib endoleak. Additionally, the risk of rupture is high when re-expansion of an aneurysm occurs after sac regression after EVAR. Therefore, close follow-up is mandatory for patients with IND after EVAR.
