摘　　要：探讨螺旋CT血管造影(SCTA)检查颈动脉狭窄的准确性,以及用SCTA代替减数血管造影(DSA)的可能性。方法:本组研究采用NASCET标准对照比较SCTA与DSA的颈动脉血管造影结果,并参考部分病例手术所见,以评估SCTA检查颈动脉狭窄的准确性。结果:本组29例颈动脉狭窄中,SCTA对照DSA的诊断总符合率为86.2％。其中严重狭窄组的相符率为100％。结论:SCTA不仅对颈动脉狭窄程度的诊断有很高的准确性和直观性,而且能够显示DSA难以发现的附壁钙化以及血栓,故有望取代DSA在颈动脉狭窄诊断中的地位。To study the accuracy of Spiral CT Angiography(SCTA) in the preoperative assessment of stenosis of the carotid artery and the possibility of its replacing the conventional angiography. Me-thods: Spiral CT images of 29 cases of carotid stenosis were compared to DSA in assessing the degree of stenosis by using the NASCET guide-lines. Results: The degree of carotid artery stenosis on the SCTA correlated well with that of DSA in 25 out of 29 cases(86.2%). The presence of severe stenosis or occlusion was correctly identified in 6 of 6 cases(100%). Conclusions: SCTA is an accurate detective technique in the preoperative assessment of atherosclerotic carotid stenosis.
