下肢动脉粥样硬化不同诊断方法对照研究

Diagnosis of atherosclerosis of lower extremity:a comparative study of different methods

通过对６例患者１０条股动脉的二维和彩色血流显像与Ｘ线造影和手术的对照研究，发现该技术可以明确地反映病变股动脉的形态、内径、截面积、管壁的厚度和粥样斑块的大小和范围。其测定股动脉内径和狭窄率也与相应部位Ｘ线造影的测量结果相关（ｒ分别为０．８３和Ｏ．８６，Ｐ＜０．００１）。

Abstract Ten femoral arteries were studied by two dimensional echocardiography and color flow imaging,arteriography and surgery in 6 patients.The results showd that the circumferential imaging of arterial wall under the endothelial surface could be clearly obtained by ultrasound technique,including the shape and extension of atheromatous plaque,luminal diameter,area,and the thickness of vascular wall.There were good correlations of the femoral arterial diameter and stenosis rate measured by ultrasound with those measured by arteriography(r=0.83 and 0.86,P<0.001,respectively).The study demonstrated the possibility of displaying the early atherosclerosis,particularly the plaques at the posterior arterial wall,of which the arteriography could not be detected.
