Abstract:
Objective To evaluate the safety and efficacy of endovascular intervention to revise peripheral bypass problems through prosthetic approach.Methods Among 17 cases undergoing graft bypass anastomotic stenosis and graft thrombosis was identifled in 16 cases(inflow or outflow obstructive lesions in 10),inflow obstructive lessions in 1(without anastomotic and graft thrombosis).All revision procedures were taken under local anesthesia,16 patients were treated by means of surgical thrombectomy followed by endovascular intervention through prosthesis itself in addition to one who had no thrombectomy.The graft patency and clinical outcome were observed.Resuits Thirteen stents were implanted in 13patients with distal anastomotic stenosis and 1 with proximal anastomotic stenosis including 10 stentings/PTAs in iliac popliteal,posterior tibial or anterior tibial arteries.One stent was implanted in 1 patient with common femoral stenosis.Stenting were not used(abandoned)in 2 patients,of which one underwent a foot amputation and calf gangrene occurred a week later,and the other had a redo of grafting.Follow-up time is 1-35 months.with an average of 12±4 months.One had a below-knee amputation two months after intervention,the other had symptoms recurred and treated with a redo 3 months afterwards.the third died of myocardial infarction six months later.Grafts remained patent in the rest 13 patients at follow-up.Conclusions Endovascular intervention through prosthesis is a safe and effective method,which offers an alternative means to treat anastomotic stenosis.inflow or outflow obstructive lesions.
