Delayed rupture of the iliac artery after endovascular therapy

Published:February 09, 2023DOI:


      Iliac artery rupture during endovascular therapy (EVT) is a life-threatening complication requiring prompt diagnosis and treatment. However, delayed rupture of the iliac artery after EVT is rare, and its predictive value remains unknown. Herein, we present the case of a 75-year-old woman who developed delayed iliac artery rupture 12 h after balloon angioplasty and placement of a self-expandable stent in the left iliac artery. Hemostasis was achieved with a covered stent graft. However, the patient died of hemorrhagic shock. From the review of previous case reports and the pathological findings of the current case, increased radial force due to overlapping stent and kinking of the iliac artery may be associated with delayed iliac artery rupture.

      Learning objective

      Delayed iliac artery rupture after endovascular therapy is rare but with a poor prognosis. Hemostasis can be achieved using a covered stent; however, the outcome could be fatal. Based on pathological findings and previous case reports, increased radial force at the stent site and kinking of the iliac artery may be associated with delayed iliac artery rupture. Self-expandable stent probably should not be overlapped at the site where kinking is likely to occur, even if long stenting is needed.
