摘　　要：目的:探讨下肢动脉硬化闭塞症患者与下肢血栓性脉管炎患者下肢动脉彩超的特点。方法:选取2016年9月至2018年9月期间广州市中医医院收治的115例下肢动脉硬化闭塞症患者和115例下肢血栓性脉管炎患者作为研究对象。将其中的115例下肢动脉硬化闭塞症患者作为A组,将其中的115例下肢血栓性脉管炎患者作为B组。对两组患者均进行彩超检查。然后观察两组患者股总动脉、股浅动脉、胫后动脉、胫前动脉及腘动脉的峰值血流速度、血流阻力指数、内膜及回声的情况。结果:A组患者的股浅动脉、股总动脉、腘动脉、胫后动脉及胫前动脉的峰值血流速度均低于B组患者,P<0.05。两组患者股浅动脉、股总动脉、腘动脉、胫后动脉及胫前动脉血流的阻力指数相比,P>0.05。A组患者下肢动脉内膜的厚度增加,且表面毛糙,其闭塞动脉的管腔内有较强的回声斑块。B组患者下肢动脉的内膜无明显的改变,其动脉管腔内无回声。结论:进行下肢动脉彩超检查时,下肢动脉硬化闭塞症患者下肢动脉的峰值血流速度低于下肢血栓性脉管炎患者,其下肢动脉内膜及回声的情况与下肢血栓性脉管炎患者有一定的差异,其下肢动脉血流的阻力指数与下肢血栓性脉管炎患者无明显的差异。Objective:To investigate the characteristics of lower extremity arterial color doppler ultrasound in patients with arteriosclerosis obliterans and thromboangiitis obliterans.Methods:115 patients with lower extremity arteriosclerosis obliterans and 115 patients with lower extremity thromboangiitis obliterans were selected from September 2016 to September 2018 in Guangzhou Traditional Chinese Medicine Hospital.115 patients with lower extremity arteriosclerosis obliterans were treated as group A and 115 patients with lower extremity thromboangiitis obliterans as group B.Color doppler ultrasound was performed in both groups.Then the peak blood flow velocity,blood flow resistance index,intima and echo of the common femoral artery,superficial femoral artery,posterior tibial artery,anterior tibial artery and popliteal artery in the two groups were observed.Results:The peak flow velocity of the superficial femoral artery,common femoral artery,popliteal artery,posterior tibial artery and anterior tibial artery in group A was lower than that of group B(P<0.05).The blood flow resistance indexes of superficial femoral artery,common femoral artery,popliteal artery,posterior tibial artery and anterior tibial artery in the two groups were compared,and P>0.05.In group A,the intima thickness of lower extremity arteries increased and the surface was rough,and there were strong echo plaques in the lumen of occluded arteries.In group B,there was no significant change in the intima of lower extremity arteries and no echo in the arterial lumen.Conclusion:lower limb artery colour to exceed check,the peak value of lower limb arteriosclerosis occlusion disorder in patients with lower limb artery blood flow velocity is lower than the lower extremities thrombosis in patients with vasculitis,the lower limb arterial intima and echo with the condition of the lower extremities thrombosis in patients with vasculitis has certain difference,the lower limb artery blood flow resistance index and lower extremities thrombosis vasculitis with no obvio
