Abstract
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.
