The use of balloon-expandable stent grafts for the management of acute arterial bleeding.

PURPOSE To evaluate the efficacy and safety of balloon-expandable stent grafts in the emergency treatment of acute arterial hemorrhage. MATERIALS AND METHODS Between July 2008 and December 2009, 15 patients with acute arterial hemorrhage from inflammatory vessel erosion or pseudoaneurysms (n = 9), noninflammatory pseudoaneurysms (n = 3), or iatrogenic vessel injury (n = 3) were treated with emergency stent graft implants. The primary study endpoints to determine treatment efficacy and safety were survival, complication rates, and freedom from recurrent hemorrhaging or reintervention. The secondary study endpoints were technical and clinical success. RESULTS The survival rate was 73% with a mean follow-up of 119 days ± 220. The complication rate was 20%. The procedure was technically successful in 13 of 15 (87%) patients. One endoleak persisted and led to a reintervention rate of 7%. The bleeding ceased immediately after stent graft implantation in 14 patients. CONCLUSIONS Implantation of balloon-expandable stent grafts is a safe and effective emergency treatment for acute arterial hemorrhage from visceral and peripheral vessels.
