METHODS: Our study included 203 consecutive patients receiving EVT for atherosclerotic obstruction of aortoiliac, femoro-popliteal, and below-knee arteries between January 2019 and February 2020. The lesion characteristics were determined according to categories in the TASC-II. Operational failure is the inability to position the guidewire through the occluded lesion following percutaneous intervention or achieve distal perfusion following EVT.
RESULTS: In our study, we observed 136 patients (%6) with TASC A-B lesions and 67 patients (%33) with TASC C-D lesions. EVT was performed on the femoro-popliteal artery in 59.4% of the patients, on the aortoiliac artery in 30.7%, and on the below-the-knee artery in 9.9%. mGPS was an independent predictor of severe PAD (OR: 17.943, 95% CI: 5.120-62.882; p < .001) and procedural success (odds ratio: 0.004; 95% CI: 0.001-0.099; p < .001). Additionally, we identified age and the presence of a TASC D lesion as independent predictors of interventional success (OR: 0.938, 95% CI: 0.819-0.979; p: .034; OR: 0.104, 95% CI: 0.107-0.643; p: .015, respectively).
CONCLUSIONS: We determined that mGPS independently predicts PAD complexity and severity based on TASC-II classification; the EVT success rate is lower in patients with high mGPS.
方法:我们的研究包括203例连续接受EVT治疗的主髂动脉粥样硬化梗阻患者,股骨—————————————————————————————————————————————————————————————————————————————————————————————————以及2019年1月至2020年2月之间的膝盖以下动脉。根据TASC-II中的类别确定病变特征。手术失败是在经皮介入后无法将导丝定位通过闭塞病变或在EVT后无法实现远端灌注。
结果:在我们的研究中,我们观察到136例TASCA-B病变患者(%6)和67例TASCC-D病变患者(%33).在59.4%的患者中,对股骨—————————————————————————————————————————————————————————————————————————————————————————腹髂动脉占30.7%,膝关节以下动脉占9.9%。mGPS是严重PAD(OR:17.943,95%CI:5.120-62.882;p<.001)和手术成功(比值比:0.004;95%CI:0.001-0.099;p<.001)的独立预测因子。此外,我们确定年龄和TASCD病变的存在是介入成功的独立预测因素(OR:0.938,95%CI:0.819-0.979;p:.034;OR:0.104,95%CI:0.107-0.643;p:.015).
结论:我们确定mGPS根据TASC-II分类独立预测PAD的复杂性和严重程度;高mGPS患者的EVT成功率较低。
