摘　　要：目的通过比较下肢动脉硬化闭塞症(ASO)经皮血管腔内成形术(PTA)前后的经皮氧分压(TcPO_(2))、踝肱指数(ABI)、趾肱指数(TBI)的变化,评价TcPO_(2)在评估下肢ASO患者PTA疗效的临床价值。方法ASO患者101例,下肢ASO患肢111例,行PTA术后2~9 d复查TcPO_(2)、ABI及TBI。根据有无T2DM分为T2DM组(n=57)及单纯ASO组(ASO,n=44)。根据术前TcPO_(2)水平分为重度缺血组(n=38)、轻度度缺血组(n=37)及正常组(Con,n=36)。根据手术方式分为球囊扩张术组(n=56)、球囊扩张+支架植入术组(n=37)及支架植入术组(n=18)。比较3种检测方法的检测结果。结果重度及轻度缺血组术后TcPO_(2)、ABI、TBI高于术前(P<0.05)。球囊扩张术及支架术组术后TcPO_(2)、ABI、TBI高于术前(P<0.05),球囊扩张+支架植入术组术后ABI、TBI高于术前(P<0.05)。结论TcPO_(2)可作为评估下肢ASO行PTA疗效的临床指标之一。TcPO_(2)在评价微循环状态方面优于ABI、TBI。ObjectiveTo identify the clinical value of percutaneous oxygen partial pressure(TcPO_(2))in evaluating the efficacy of percutaneous transluminal angioplasty(PTA)in lower extremity arteriosclerosis obliterans(ASO)patients by comparing the changes of TcPO_(2),ankle brachial index(ABI)and toe brachial index(TBI)before and after PTA.MethodsTcPO_(2),ABI and TBI of 111 patients with ASO were examined 2~9 days after PTA.According to the presence of type 2 diabetes mellitus(T2DM),they were divided into T2DM group(n=57)and ASO group(n=44).According to the level of TcPO_(2) before surgery,they were divided into severe ischemia group(n=38),mild ischemia group(n=37)and normal group(n=36).According to the surgical methods,they were divided into balloon dilation group(n=56),balloon dilation+stent implantation group(n=37)and stent implantation group(n=18).ResultsThe postoperative TcPO_(2)(mmHg),ABI and TBI in severe and mild ischemic groups were higher than before operation(P<0.05).TcPO_(2),ABI and TBI in balloon dilation and stenting group increased after operation(P<0.05).The postoperative ABI and TBI were higher in the balloon dilation+stent implantation group than before operation(P<0.05).ConclusionTcPO_(2)can be used as one of the clinical indicators to evaluate the efficacy of PTA in lower extremity ASO.TcPO_(2)is superior to ABI and TBI in evaluating microcirculation status.
