下肢动脉硬化闭塞是因下肢动脉壁硬化、内膜增厚或出现硬化斑块及血栓,导致动脉狭窄甚至闭塞的一组缺血性疾病。随着介入治疗的发展,经导管动脉溶栓、经皮腔内血管成形术及血管内支架置入术治疗下肢闭塞性病变已普遍开展〔1〕。彩色多普勒超声是下肢动脉疾病无创性检查的首选方法,既可确定动脉病变的狭窄程度及准确定位,又能对介入治疗术后血管再通情况等血流动力学信息提供帮助。笔者收集15例(18支病变血管)经血管内支架置入术治疗的患者的临床资料,探讨彩色多普勒超声在动脉硬化闭塞症患者介入术前及术后的临床价值。
Lower extremity arteriosclerosis occlusion is due to lower extremity arterial wall hardening, intimal thickening or plaque and thrombus, leading to arterial stenosis or occlusion of a group of ischemic diseases. With the development of interventional therapy, transcatheter arterial thrombolysis, percutaneous transluminal angioplasty and endovascular stent placement for the treatment of occlusive disease of the lower limbs have been commonly carried out 〔1〕. Color Doppler ultrasound is the preferred method of non-invasive examination of arterial disease of the lower extremities, which not only determines the degree of stenosis and the accurate localization of arterial lesions, but also helps in hemodynamic information such as recanalization after operation. The author collected 15 cases (18 lesions of blood vessels) by stent placement in patients with clinical data to explore the clinical value of color Doppler ultrasound in patients with arteriosclerotic occlusive disease before and after interventional surgery.
