Abstract

The accuracy of duplex-scanning and angiography in detecting ulceration in the carotid arteries was evaluated. Sixty-nine patients underwent duplex-scanning and carotid arteriography, and the findings were blindly compared to the operative specimens. Duplex-scanning had a significantly higher sensitivity (90 vs 48%, P less than 0.001) and accuracy (88 vs 59%, P less than 0.001) than angiography. There was no difference in specificity (84 vs 89%, P = 0.28). Comparison was also made between conventional arch angiography and selective carotid angiography in detecting ulceration. There was no significant difference between the methods (sensitivity 47 vs 50%, specificity 82 vs 100%). Finally, interobserver variability in detecting ulceration with duplex-scanning was evaluated in double-blind evaluation of the duplex-scans. The interobserver agreement was 84%. Duplex-scanning seems to be superior to angiography in detecting ulcerations in the extracranial carotid artery.

摘要

评估了双功扫描和血管造影术检测颈动脉溃疡的准确性。69例患者接受了双功扫描和颈动脉血管造影，其结果与手术标本进行了盲法比较。双功扫描的敏感性（90%对48%，P<0.001）和准确性（88%对59%，P<0.001）显著高于血管造影。特异性无差异（84%对89%，P=0.28）。还比较了传统弓上血管造影和选择性颈动脉血管造影检测溃疡的情况。两种方法之间无显著差异（敏感性47%对50%，特异性82%对100%）。最后，在双盲评估双功扫描时评估了观察者间在检测溃疡方面的变异性。观察者间一致性为84%。双功扫描在检测颅外颈动脉溃疡方面似乎优于血管造影。
