Objective To explore the technical methods and clinical efficacy of interventional treatments on atherosclerosis obliterans in lower-limb arteries.Methods Fifty-three patients with forty-eight stenosis changes and twenty-five occlusive changes received interventional treatments including percutaneous transluminal angioplasty(PTA),implantation of stent(IS),subintimal angioplasty(SIA) and mechanical thrombectomy(MTE).Results Ten changes with simple PTA and 20 with ally of IS(19 self-expandable stents and 5 recoiling stents),8 changes with simple MTE and 14 changes with ally of IS(19 self-expandable stents and 1 recoiling stents),5 changes with simple SIA and 11 changes with ally of IS(17 self-expandable stents and 2 recioling stents).In 66 successfully treated changes,there were 41 changes with relief of symptoms and signs,20 cases with obvious improvement,and 5 changes without any improvement.But 4 cases suffering operation to relieve the tension of lower extremities from ischemia-reperfusion injury and 2 cases suffering amputation.All the patients were followed-up for 2-33 months(mean 10.5 months).Among them,three cases with restenosis did not receive any interventional recanalisation after 6 months and two cases with restenosis after simple PTA successfully received IS.Conclusion Various interventional treatments have respective strong points to treat different atherosclerosis obliterans of arteries.Comprehensive application of them can be a safe and effective method for atherosclerosis obliterans of lower-limb arteries.
