摘　　要：目的探讨下肢动脉硬化闭塞症(ASO)的腔内介入治疗方法和疗效。方法对21例下肢ASO患者行经皮血管成形术(PTA)和PTA后选择性支架置入术,观察术前和术后7天踝肱指数(ABI)的变化,随访6～24个月观察疗效。结果 21例的23条肢体有20条腔内介入治疗成功,单纯PTA12条,PTA后支架置入8条,术后死亡1例。介入治疗成功者术后7天ABI均较术前明显升高。有随访结果的16例,14例达到保肢目的,平均临床疗效评分结果介于较好到好之间。结论腔内介入治疗能安全、有效地改善下肢动脉硬化闭塞症的缺血症状,在各项临床治疗手段中占有重要地位。精细的介入操作、全面的围手术期处理和术后随访有助提高腔内介入治疗的成功率和中、远期疗效。Objective To explore the method and curative effect of intravascular interventional therapy on low extremity arteriosclerosis obliterans（ASO）.Methods 21 patients with ASO were treated with percutaneous angioplasty（PTA） and followed by stent implantation.The index of ankle brachial index（ABI） was observed before and 7 days after operation.Then,follow-up observation was carried out from 6 to 24 months.Results Of the 23 cases of limbs,20 cases were succeeded,in which there were 12 cases of PTA,and 8 cases of PTA with stent implantation.The index of ABI of 7 days after operation was significantly higher than that of before operation.As for the result of follow-up observation in 16 cases,14 cases had their low extremity survived,which obtained medium scores of curative effect.Conclusion The method of intravascular interventional therapy can safely and effectively improve the symptoms of patients with ASO.Its curative effect can be increased by refined operation and comprehensive perioperative treatment.
