Abstract
The aim of our study was to compare stenosis grade in peripheral arterial diseases by color Doppler and MDCT angiography. 75 patients having symptoms related to lower or upper limb peripheral arterial occlusive disease were examined by Doppler USG and CT angiography. The data were analyzed in 13 arterial segments. (5 in upper limb and 8 in lower limbs). Stenosis grading was assigned from 1 to 5, one as normal and 5 as complete block. The sensitivity, specificity and accuracy of Doppler USG and CTA were determined using statistics. A total of 1071 arterial segments were compared on CT angiography and Doppler USG. We found 419 (39.1%) abnormal disease arterial segments on CT angio. The sensitivity, specificity, and accuracy of MDCT angiography was 92.9%, 82.2 %, and 85.6%, respectively. Color Doppler ultrasonography for peripheral arterial disease is excellent first investigation for evaluation of peripheral arterial disease in upper or lower limbs beyond inguinal region and beyond 2nd part of subclavian A in upper limbs.
