The former studies have shown Concentrated Xuefu Zhuyu Pill have effects on many pathological factors of restenosis, such as platelet agregation and adhesion, SMC proliferation,and it can prevent restenosis after PTA (percutanous transluminal angioplasty) of experimental illac artery AS of New Zealand rabbits.

因此，在动物实验证明血府逐瘀浓缩丸具有抗动脉粥样硬化，抑制AS家兔血管SMC增生作用，以及在防治家兔动脉粥样硬化PTA后再狭窄方面有一定作用的基础上，我们开展了其对冠心病人PTCA后再狭窄的防治研究。

Results 520 arteries were examined in all, and DSA detected 130 normal, 390 abnormal (75.0%, 120 artherosclerosis, 201 stenosis, 69 occlusion). In the diagnosis of MRA to angiostegnosis , the sensitivity was 95.4%, the specificity was 96.2%, the false positive was 1.3%, and the false negative was 17.7%.

结果 检查缺血性脑血管患者的血管520条，DSA发现130条正常，390条异常（75.0％），其中动脉粥样硬化120处，狭窄201处，闭塞69处；MRA诊断血管狭窄的敏感性为95.4％，特异性为96.2％，假阳性为1.3％，假阴性为15.5％。

Color ultrasound examination are effective for the diagnosis of carotid bifurcation sterosis, and less effective for the diagnosis of the subclavicular and vertebral artery stenosis because of the poor sensitivity.

彩色多普勒超声检查可作为诊断颈动脉分叉部位血管狭窄的有效方法；而其对锁骨下动脉及椎动脉狭窄的敏感性较低，诊断价值不大。

ConclusionColor ultrasound examination are effective for the diagnosis of carotid bifurcation sterosis, and less effective for the diagnosis of the subclavicular and vertebral artery stenosis because ofthe poor sensitivity.
