目的：观察解毒通脉汤治疗闭塞性动脉硬化症的临床疗效。方法：选取246 例闭塞性动脉硬化症患者中血脉瘀阻型患者，随机分成两组，对照组120 例，患者常规口服拜阿司匹林0.1 g+辛伐他丁片20 mg，每日一次；治疗组126 例，患者在口服拜阿司匹林及辛伐他丁片的基础上，加服中药解毒通脉汤，8 周后观察患者临床症状改善情况和臂踝指数（ABI）、超敏C 反应蛋白（Hs-CRP）、持续经皮氧分压（TcPO2）变化。结果：与对照组相比，治疗组临床症状明显改善（P＜0.05），患者ABI、CRP、TcPO2 均有显著提高（P＜0.01）。结论：解毒通脉汤对闭塞性动脉硬化症血脉瘀阻型患者治疗有效，间接验证了中医因邪致瘀理论的指导意义。

This study was aimed to observe the clinical efficacy of Jie-Du Tong-Mai (JDTM) decoction (i.e., detoxification unclogg artery soup) of arteriosclerosis obliterans. A total of 246 arteriosclerosis obliterans cases with the pattern of blood stasis were selected and randomly divided into two groups. In the control group of 120 cases, 0.1 g of aspirin and 20 mg of simvastatin tablets were orally administrated, once a day. In the treatment group of 126 cases, JDTM decoction was combined on the basis of oral administration of aspirin and simvastatin tablets. After 8 weeks of treatment, observations were made on improvement of clinical symptoms and changes of ABI, Hs-CRP,TcpO2. The results showed that compared with the control group, clinical symptoms of the treatment group were obviously improved (P < 0.05). And the ABI, CRP, TcpO2 were also obviously increased (P < 0.01). It was concluded that JDTM decoction was effective in the treatment of arteriosclerosis obliterans with the pattern of blood stasis.
