目的探究彩超用于下肢动脉硬化闭塞症与血栓闭塞性脉管炎诊断中的临床效果。方法回顾性分析2013年3月—2016年11月该院收治的70例下肢动脉硬化闭塞症与血栓闭塞性脉管炎患者彩超资料,其中下肢动脉硬化患者35例(PAD组),血栓闭塞性脉管炎患者35例(TOA组);对患者进行彩超检查,对比分析患者的彩超资料。结果下肢动脉硬化闭塞症内膜增厚,可见形态各异、大小不一的强回声斑块堆积;血栓闭塞性脉管炎B超显示管腔内回声略高,无强回声斑块。两种疾病CDFI、PW特点大致相同,CDFI显示闭塞管腔内无血流信号,PW显示闭塞段动脉管腔内不能引起多普勒频谱。结论彩超用于下肢动脉硬化闭塞症与血栓闭塞性脉管炎的鉴别诊断有重要的临床意义,对疾病分析有较高的准确性,能够为临床诊断提供有价值的参考意见。
Objective To investigate the clinical effect of color Doppler ultrasound in the diagnosis of arteriosclerosis obliterans and thromboangiitis obliterans in lower extremities. Methods A retrospective analysis of 70 patients with lower extremity arterial occlusive disease and thromboangiitis obliterans in our hospital from March 2013 to November 2016 was performed. Among them, 35 cases of lower extremity arteriosclerosis (PAD group), thrombo-occlusive Thirty-five patients with vasculitis (TOA group) were included in this study. Color Doppler echocardiography was performed on the patients and color Doppler ultrasound data were analyzed. Results The lower extremity arteriosclerosis obliterans intimal thickening, showing different shapes, the size of the strong echo plaque accumulation; thromboangiitis obliterans B ultrasound showed slightly higher echo within the lumen, no strong echo plaque. CDFI, PW characteristics of the two diseases are roughly the same, CDFI shows no blood flow in the occluded lumen signal, PW shows occluded artery lumen can not cause Doppler spectrum. Conclusion The application of color Doppler ultrasound in the differential diagnosis of arteriosclerosis obliterans and thromboangiitis obliterans has important clinical significance.
