【摘要】 目的探讨下肢动脉硬化闭塞症(ASO)数字减影血管造影(DSA)检查及血管腔内治疗的疗效。方法对下肢ASO患者的病变肢体先行DSA检查,评估血管狭窄程度、闭塞情况和侧枝循环形成情况,采用球囊扩张和支架植入进行血管腔内治疗。结果 19例患者中,22条肢体有明显病变,血管狭窄大于40%;球囊扩张和支架植入治疗14例,治疗后造影显示血管再通;18条肢体明显好转,2条肢体部分好转,2条肢体无效,总有效率90.9%。结论 DSA能准确评价缺血肢体的血运情况,对手术方案的确定有重要指导意义。血管内治疗对于下肢ASO患者疗效肯定,安全可行。更多还原

【Abstract】 Objective To investigate the efficacy of digital subtraction angiography(DSA) and endovascular treatment in arteriosclerosis occlusion(ASO)of the lower extremity.Methods The diseased limbs underwent DSA examination to assess the degree of stenosis,occlusion of the situation and collateral formation.Balloon dilatation and stenting were adopted in endovascular therapy.ResultsOf 19 patients,22 limbs had significant lesions of stenosis more than 40%.Balloon dilatation and stent implantation were used in 14 cases.After treatment,DSA images displayed recanalization,18 limbs were markedly improved,two limbs were improved partialy,and two limbs were physically invalid.The total effectiveness rate was 90.9%.Conclusion DSA can accurately evaluate blood circulation of ischemic limbs and guide for planning surgery.Balloon dilatation and stent implantation are effective,feasible and safe for ASO of the lower extremity.更多还原
