Collapse and Thrombosis of an Iliac Branch Endovascular Device Following Blunt Force Trauma
Autumn Stevens, Peter Henke, Frank Davis, Jeri Stevens, Nicholas OsborneIliac branch endovascular device thrombosis following blunt force trauma has rarely been reported. We describe an 81-year-old man who developed proximal aortobiiliac endograft collapse with subsequent thrombosis after blunt force trauma occurring two months following endovascular aneurysm repair. The patient delayed vascular follow-up for one year and later presented at routine surveillance with progressive bilateral hip and buttock claudication. Despite chronic therapeutic anticoagulation for atrial fibrillation, the patient developed progressive thrombosis with ischemic symptoms. The case highlights a rare mechanical cause of post-EVAR aortoiliac thrombosis and demonstrates the importance of early vascular imaging and consultation following traumatic injury in post-EVAR patients.
