Mechanical Trauma as a Cause of Late Complications after AneuRx® Stent Graft Repair of Abdominal Aortic Aneurysms

By Zvonimir Krajcer, Kamal Gupta and Kathy G. Dougherty


We present a series of 4 patients in whom mechanical trauma was identified as a factor in the development of late complications after AneuR® Stent Graft placement for repair of abdominal aortic aneurysms. In all 4 patients, Type I or III endoleaks (and pseudoaneurysms in 2 patients) were discovered several months after abdominal aortic aneurysm repair with the AneuRx device. Two patients had sustained blunt abdominal trauma in a car accident, one had suffered a traumatic fall, and another had been participating in vigorous rowing activity. In all patients, the trauma had occurred several months before the diagnosis of endoleak or pseudoaneurysm (or both) was established. In all patients, follow-up computed tomographic scans identified the complications. In conclusion, blunt mechanical injury is an unrecognized factor contributing to the late failure of endovascular stent grafts. Vigorous physical activity may also contribute to graft disruption or to the separation of modular components. (Tex Heart Inst J 2003;30:186–93
