Objective To explore the clinical experience of endovascular treatment for arteriosclerosis obliterans (ASO) of lower extremities.Methods Endovascular treatment were performed on 22 patients (26 limbs) suffering from ASO which were diagnosed by magnetic resonance angiography (MRA).The clinical efficacy after operation was analyzed.Results Twenty-two lower extremities of 18 patients successfully accepted endovascular treatment with 12 stents planted without major complications.Four cases failed to endovascular treatment and 2 of them converted to bypass surgery.The clinical symptoms of limb ischemia vanished or significantly improved after treatment.The ankle brachial index (ABI) of affected extremities increased from 0.35±0.13 (before operation) to 0.70±0.15 (after operation),P0.01.During the follow-up of 2-18 months,3 cases suffered re-occlusion of artery of lower extremity,in them one case received drug treatment and 2 cases resolved by percutaneous transluminal angioplasty (PTA) and stenting again.Conclusion Endovascular treatment for ASO of lower extremities has such advantages as minimal invasiveness,reduced complications and repeatability.It may serve as a more promising choice of method to clinical treatment of ASO.
