Abstract/OtherAbstract:
OBJECTIVE: Placement of arterial endoprostheses across the inguinal ligament is generally thought to be contraindicated for fear of device kinking, fracture, or occlusion and possible obliteration of the deep femoral artery (DFA). We present a series of selected patients who underwent insertion of polytetrafluoroethylene-covered nitinol stents (Viabahn stent grafts. W. L. Gore and Associates Inc, Flagstaff, Ariz) crossing the middle common femoral artery (CFA) on an emergency basis or who were considered high risk for open surgery. METHODS: We treated 16 patients with 17 lesions adjacent to or within the CFA with stent grafts that originated in the common iliac (two) or external iliac (15) artery and terminated in the distal CFA (12), DFA (three), or superficial femoral (two) artery. Stent grafts were placed on an elective (10) or emergency (seven) basis for arterial occlusive disease (10), bleeding (six), and aneurysmal disease (one). Comorbidities favoring endovascular treatment were high medical risk (10) previous scarring (four), morbid obesity (two), and dense arterial calcification precluding open surgical repair (one). RESULTS: The DFA was deliberately sacrificed in one of the 17 cases. No patient suffered major complications after the procedure. All grafts remained patent based on duplex ultrasound imaging during follow-up (mean, 12.3 months; range, 1-58 months). Two patients required an additional endovascular intervention to treat inflow or outflow stenoses during follow-up, yielding a 2-year primary patency rate of 93.8% and assisted primary patency rate of 100%. CONCLUSIONS: These results suggest that selective placement of Viabahn stent grafts across the inguinal ligament to treat arterial occlusive disease or bleeding may prove to be safe, effective, and associated with acceptable patency rates. This strategy helps avoid complicated open arterial surgery in high-risk patients with associated multiple medical risk factors or hostile scarred groins.
