Operative CDI was performed during 125 general surgical operations (53
hepatic, 25 biliary, 24 pancreatic, 7 esophagogastric, 10 pulmonary, 3
kidney transplant, and 3 soft tissue operations). Operative CDI provided
beneficial information in 108 of 125 operations (86.4%). On the basis of
operative CDI findings, surgical management was altered in 34 of 125
operations (27.2%), most frequently hepatic and pancreatic operations.
Operative CDI demonstrated advantages over B-mode imaging in (1) detection
and localization of small blood vessels that are impossible or difficult to
identify by B-mode imaging, (2) rapid and definitive distinction of blood
vessels from other hypoechoic areas, such as tissue spaces and ducts, (3)
determination of the relation of tumors to vascular structures such as
vascular invasion of carcinoma, (4) confirmation of blood flow to organs
after surgical procedures, and (5) clearer needle localization for guidance
of needle placement by color motion marking.
