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.
一名78岁男性在就诊前7年接受了血管内主动脉瘤修复术(EVAR)。尽管6个月前瘤腔稳定,但患者入院时出现休克,CT显示由于髂颈扩张(IND)导致Ib型内漏,主动脉破裂并迅速扩张。采用血管内策略排除了动脉瘤瘤腔。喇叭口状髂支可导致与Ib型内漏相关的IND。此外,EVAR术后瘤腔缩小后动脉瘤再次扩张时破裂风险很高。因此,EVAR术后有IND的患者必须密切随访。
