Forty patients with symptomatic aortoiliac and/or femoropopliteal occlusive arterial disease subjected to angiography were studied with duplex ultrasonography. The duplex scanning of the aortic, iliac, femoral and popliteal segments had a sensitivity of 93% in detecting significant stenoses and a specificity of 91%. The positive and negative predictive values were 75% and 98%, respectively. The sensitivity was relatively low in low-flow segments distal to total occlusions especially in patients with severe iliac disease and multiple distal femoropopliteal lesions. The results demonstrate the reliability of duplex scanning in detecting aortoiliac and femoropopliteal lesions.
对40例有症状的主髂动脉和/或股腘动脉闭塞性动脉疾病且接受血管造影的患者进行了双功超声检查。对主动脉、髂动脉、股动脉和腘动脉节段的双功扫描在检测明显狭窄方面的敏感性为93%，特异性为91%。阳性和阴性预测值分别为75%和98%。在完全闭塞远端的低血流节段，敏感性相对较低，尤其是在患有严重髂动脉疾病和多处股腘动脉远端病变的患者中。结果表明双功扫描在检测主髂动脉和股腘动脉病变方面具有可靠性。
