Doppler noninvasive vascular scanning for the diagnosis of arteriosclerotic occlusion of the lower limbs / 中华普通外科杂志

ABSTRACT

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.
