纳入标准:
|
(1)符合西医诊断标准;①年龄>40岁,有吸烟、糖尿病、高血压、高脂血症等高危因素,存在下肢缺血的临床表现,如间歇性跛行、患肢皮温下降、麻木、皮肤毛发脱落等患肢足背或胫后动脉搏动减弱或消失;②ABI≤0.9;③彩色多普勒超声、CTA、MRA或DSA等影像学检查显示相应下肢动脉的狭窄或闭塞等病变;
(2)符合中医诊断标准(痰湿阻络证)
根据国家中医药管理局十一五重点专科外科协作组的脱疽未溃期的临床诊疗方案和中药新药临床指导原则-中医症候临床研究指导原则(2002版)的有关内容:

血瘀证:主证:①下肢酸痛,皮色暗红或皮温低下;②间歇性跛行;③足背、胫后动脉搏动减弱或消失;
次证:患肢皮肤干燥脱屑,患肢发凉、麻木,足趾甲增厚,汗毛稀疏,患肢的抽痛、肌肉抽搐。
舌象:暗红,有瘀点或瘀斑;脉象:脉沉、涩。
具备血瘀证的主症,同时满足痰湿证和血瘀证中次症的任意一项,结合舌脉即可诊断。
(3)PAD分级属于Fontaine Ⅱ, Rutherford Ⅰ(1-3)的患者,临床表现以间歇性跛行为主且近 1月无明显加重;
(4)40<年龄≤80岁,性别不限;
