As operative vascular ultrasound examination, color doppler imaging was used for the first time during four operations for renal artery stenosis. Immediately after laparotomy operative color doppler imaging provided accurate diagnosis of the extent and degree of the arterial stenosis, and thus helped decide the type of operative procedure. Following vascular reconstruction, repaired vessels were also examined in determining the presence or absence of vascular defects. As compared to operative ultrasonography by B-mode or duplex scanning, operative color doppler imaging is useful in readily delineating high-grade stenotic arteries and in measuring the degree of stenosis. However, further studies are required for evaluation of color-coded flow patterns during peripheral vascular surgery.
