目的通过与血管造影比较,评价CT血管造影(CTA)和无创多普勒血管检查在下肢动脉硬化闭塞症中的诊断价值.方法对64例诊断为下肢动脉硬化闭塞症患者的97条肢体检查结果进行对比研究,以造影检查结果为“金标准”,了解多普勒检查结果的敏感性和特异性,并比较在同一时间段内进行多普勒和CTA检查结果的符合率差异有无统计学意义.统计学分析采用SPSS16.0系统,x2检验.结果在髂动脉、股总动脉、股浅动脉、足背动脉和胫后动脉节段,无创多普勒血管检查的诊断符合率与CTA比较,差异无统计学意义(P＞0.05).胭动脉节段无创多普勒的诊断符合率与CTA比较,差异有统计学意义(P＜0.05),多普勒准确性更高.结论在诊断下肢动脉硬化闭塞症方面,无创多普血管勒检查具有无创、便捷、准确性高的特点和优势,值得推广应用.

Objectives To compare Doppler noninvasive vascular testing and computed tomographic angiography(CTA) with vascular angiography in the assessment of arteriosclerotic occlusion of the lower limbs. Methods In this study 97 lower extremities in 64 patients suffering from arteriosclerotic occlusion underwent both Doppler and CTA plus angiography. Angiogram results were taken as golden standard.The sensitivity and specificity of Doppler was calculated,the diagnostic accuracy of Doppler scanning and CTA plus angiography was calculated and compared.The statistic analysis was performed using x2 test in SPSS 16.0 format. Results Compared with CTA,Doppler scanning is equally accurate at the segments of iliac artery,common femoral artery,superficial femoral artery,dorsal pedis artery and posterior tibial artery (P ＞ 0.05).At segment of popliteal artery,Doppler scanning yields more accurate results (P ＜0.05 ). Conclusions Being noninvasive convenient and of good accuracy,Doppler examination has a role for the diagnosis of arteriosclerotic occlusion of the lower limbs.
