【摘要】目的 提高多普勒超声对下肢动脉闭塞性疾病的诊断水平。方法 用方向性多普
勒血流仪对１２０条正常下肢和６６条动脉闭塞性病变下肢动脉血流进行了分段检测。对正
向波峰速（PFV）、反向波峰速（PRV）、加速时间（AT）和减速时间（DT）进行了测量和比
较。结果 正常组下肢动脉流速从近到远逐渐减慢，其远心端PFV、PRV、AT和DT与近心端的
比值均＜1.0。病变组的PFV和PRV均比正常组慢（Ｐ＜0.01），而AT和DT则长于正常组
（Ｐ＜0.01），同时发现狭窄（＞50％）或闭塞（有侧支循环形成）部位远端与近端DT的比
值＞1.0。结论 与动脉造影相比较，多普勒超声定位诊断的符合率为91％（60/66）。

【Abstract】 Objective In order increase the diagnostic standard of Doppler ultrasound to arterial
occlusive disease in the lower limbs.Methods 120 normal lower limbs and 66 lower limbs with arterial
occlusive disease were measured by directional Doppler blood velocity detector in different segment
s.The peak forward velocity(PFV)，peak reverse velocity(PRV)，acceleration time(AT)，and
deceleration time(DT) were determined and compared.Results The blood flow velocity of the lo
wer limb arteries was gradually slowed down from the proximal to the distal in the normal group.The
ratio of distal to proximal PFA,PRV,AT and DT was less than 1.0. PFV and PRV in the disease group
were slower than in the nornal group(Ｐ＜0.01).AT and DT in the disease group were longer than in the
normal group(Ｐ＜0.01).It was discoverd that the ratio of distal to proximal DT was greater than 1.0 in
arterial stenosis(＞50％)or occlusion (collateral artery development).Conclusion The results were
compared those of arteriogrphy.The diagnostic coincidence ratio of Doppler ultrasound for localization
was 91％(60/66).
