PERIPHERAL ISCHEMIC OCCLUSIVE ARTERIAL-DISEASE - COMPARISON OF COLOR DOPPLER SONOGRAPHY AND ANGIOGRAPHY

We examined 334 legs in 167 consecutive patients with advanced periphe ral ischemic disease using color Doppler sonography and angiography. A ngiography revealed 714 lesions (369 nonsignificant stenoses, 297 sign ificant stenoses, and 48 occlusions) in the 334 legs examined. Overall , color Doppler sonography revealed diagnostic agreement with angiogra phy in 668 of 714 lesions (93.5%), including 343 of 369 (92.9%) nonsig nificant stenoses, 279 of 297 (93.9%) significant stenoses, and 46 of 48 (95.8%) occlusions. Overestimation occurred in 26 of 369 (7%) nonsi gnificant stenoses and 3 of 297 (1%) significant stenoses. Underestima tion was observed in 15 of 297 (5%) significant stenoses and in 2 of 4 8 (4.2%) occlusions. Peak systolic velocity ratio correlated better (P < 0.01) than peak systolic velocity with diameter reduction percentag e as assessed at angiography. Color Doppler sonography is an accurate noninvasive method for evaluating patients with peripheral ischemic di sease.
