在股浅动脉阻塞的患者中，髂动脉疾病可能难以通过常用的非侵入性技术诊断。我们研究了股总动脉加速时间（收缩开始到收缩峰值），从多普勒频谱显示测量，以毫秒表示。先前的工作表明，加速时间大于或等于144 msec是异常的，并且与髂动脉狭窄（直径减小大于或等于75%）或闭塞相关。在2年的时间内，在139条患股浅动脉阻塞的肢体中，在血管造影术前立即测量加速时间。总体测试准确率为94.2%（131/139）。在血管造影正常的112侧中，加速时间正确识别了109例患者的无疾病（97.3%特异性），在27例髂动脉狭窄或闭塞中，该测试检测到22例患者的疾病（81.5%灵敏度）。这似乎是一个很好的测试，可以用大多数血管实验室通常可用的设备来完成。
In patients with superficial femoral artery obstruction, iliac disease may be difficult to diagnose by commonly used noninvasive techniques. We studied common femoral artery acceleration time (onset of systole to peak systole), as measured from a Doppler spectral display and expressed in milliseconds. Previous work has suggested that an acceleration time of 144 msec or greater is abnormal and is associated with iliac stenosis (greater-than-or-equal-to 75% diameter reduction) or occlusion. During a 2-year period, in 139 limbs with superficial femoral artery obstruction, acceleration times were measured immediately before angiography. The overall test accuracy was 94.2% (131/139). In the 112 sides with normal angiograms, the acceleration time correctly identified no disease in 109 patients (97.3% specificity), and in the 27 iliac stenoses or occlusions the test detected disease in 22 patients (81.5% sensitivity). This appears to bc a good test that can be done with equipment usually available in most vascular laboratories.
