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。
Objective To investigate the efficacy of digital subtraction angiography (DSA) and endovascular treatment of lower extremity arteriosclerosis obliterans (ASO). Methods The diseased limbs of lower extremity ASO patients were examined by DSA to assess the degree of vascular stenosis, occlusion and the formation of collateral circulation. Endovascular treatment was performed with balloon dilation and stent implantation. Results Of the 19 patients, 22 limbs had obvious pathological changes and vascular stenosis was over 40%. 14 cases were treated by balloon dilatation and stent implantation. After angiography, blood vessels recanalization was observed. Eighteen limbs were significantly improved and two limbs were partially recovered. 2 limbs invalid, the total efficiency of 90.9%. Conclusions DSA can accurately evaluate the blood supply of ischemic limbs, which has important guiding significance for the determination of surgical plans. Endovascular treatment of ASO patients with lower extremity efficacy is safe and feasible.
