摘　　要：目的探讨彩色多普勒超声对下肢动脉硬化闭塞症（LEASO）和血栓闭塞性脉管炎（Buerger病，脉管炎）的鉴别诊断价值。方法回顾性分析首都医科大学附属北京安贞医院经临床和影像学检查确诊的50例LEASO 患者（LEASO组）和24例下肢脉管炎血管患者（脉管炎组）的彩色多普勒超声，对2组患者影像学资料进行分析。结果彩色多普勒超声检查发现LEASO组患者远段血管流速较低；脉管炎组患者远段血管流速相对偏高；2组间股总、股浅、胫前、胫后动脉收缩期最大血流流速（Vmax）差异均有统计学意义[LEASO组：（79±21）cm/s, （66±19）cm/s, （20±12）cm/s, （19±17）cm/s;脉管炎组：（117±25）cm/s, （98±16）cm/s, （41±18）cm/s, （45±16）cm/s,均P〈0.05]；阻力指数差异均无统计学意义（P〉0.05）；2组间腘动脉Vmax及阻力指数差异均无统计学意义（P〉0.05）。结论彩色多普勒超声检测是LEASO和脉管炎患者诊断和鉴别的最佳无创方法。ObjectiveTo observe the value of color doppler ultrasound in the diagnosis and differential diagnosis of arteriosclerosis obliterans （LEASO） and thromboangiitis obliterans （Buerger′s disease, vasculitis）.Methods We retrospectively analyzed results of color doppler ultrasound examination of 50 cases of PWS patients and 24 cases of lower limb vasculitis. Results Vascular ultrasound examination revealed a low flow rate of distal vascular segment of LEASO patients and flow rate of distal vascular segment was relatively high in vasculitis patients. There was statistically significance of peak systolic flow velocity （Vmax） of common femoral, superficial femoral, anterior tibial and posterior tibial arteries [LEASO group：（79±21） cm/s, （66±19）cm/s, （20±12）cm/s, （19±17）cm/s; Vasculitis group：（117±25）cm/s, （98±16）cm/s, （41±18）cm/s, （45±16） cm/s, all P〈0.05] between the two groups; resistance index （RI） showed no significant difference （P〉 0.05） between the two groups; Vmax and RI of popliteal arteries between the two groups showed no significant difference （P〉0.05）. ConclusionColor doppler ultrasound is one of the best noninvasive methods for detection and differential diagnosis of LEASO and of vasculitis patients.
