摘　　要：目的评估踝臂指数(ABI)在下肢动脉硬化闭塞症(LEAOD)介入治疗中的临床价值。方法 34例患者行下肢动脉CT血管造影术检查确诊LEAOD并制定介入治疗方案,术前术后测定ABI。结果 ABI随着临床症状和血管病变严重度增加而减低,差异均有显著统计学意义(均P<0.01)。行经皮腔内球囊扩张术(PTA)及血管内支架植入治疗24例,单纯行PTA术10例。术后,ABI、患肢收缩压及脉搏波传导速度(PWV)由术前0.58±0.19、(95 75±23.61)mmHg、(1 121.86±605.99)cm/s增加为0.81±0 14、(137.44±25.66)mmHg、(1 970.61±505.30)cm/s,差异均有显著统计学意义(均P<0.01)。结论 ABI是一种无创、快捷的方法,能用于LEAOD患者介入治疗术前评估及术后随访。Objective To evaluate the clinical value of ankle brachial index （ABI） in interventional treatment of lower extremity atherosclerotic occlusive disease（LEAOD）. Methods LEAOD was determined and interventional strategies were made based on computed tomography angiography of lower extremity in 34 patients. ABI was measured pre- and post- operation. Results ABI reduced significantly as the clinical symptoms and severity of LEAOD increased （P〈0.01）. Percutaneous transluminal angioplasty （PTA） with stent implantation was performed in 24 patients, and PTA alone was performed in 10 patients. ABI,systolic blood pressure and the pulse wave velocity （PWV）of lower extremity significantly increased from 0.81±0.14,（137.44±25.66）mmHg and （1 970.61±505.30）cm/s before treatment to 0.58±0.19、（95.75± 23.61）mmHg and（1 121.86±605.99）cm/s after treatment, respectively（al P〈0.01）. Conclusion ABI is a noninvasive and easy method and may be used for preoperative assessment and post- operation fol ow- up of patients with LEAOD.
