Type III endoleaks are characterized by a problem with the endograft structure, such as fracture of the metallic structure, separation, or rupture. They constitute a rare complication, occurring in 2.1% of patients after treatment of abdominal aortic aneurysm by endovascular repair, with higher incidence in first and second generation endografts, and can occur early (after 30 days) or later. This type III classification is subdivided into IIIa -modular separation of components - and IIIb - mesh fracture or rupture involving the endograft. This case report describes an asymptomatic patient who had previously undergone infrarenal abdominal aortic aneurysm repair and underwent follow-up computed tomography which found a type IIIa endoleak with separation of the main body from the proximal extension. A second endovascular intervention was performed to seal the endoleak and correct the aneurysm.
III型内漏的特征是血管内移植物结构出现问题，如金属结构骨折、分离或破裂。它们是一种罕见的并发症，在腹主动脉瘤血管内修复治疗后的患者中发生率为2.1%，在第一代和第二代血管内移植物中的发生率更高，可在早期（30天后）或晚期出现。这种III型分类可细分为IIIa型（组件模块化分离）和IIIb型（涉及血管内移植物的网孔骨折或破裂）。本病例报告描述了一名无症状患者，该患者先前接受了肾下腹主动脉瘤修复术，并接受了随访计算机断层扫描，结果发现存在IIIa型内漏，主体与近端延伸部分分离。进行了第二次血管内干预以封闭内漏并纠正动脉瘤。
