[Preoperative evaluation of resectability of hilar bile duct carcinoma by color Doppler flow imaging and duplex Doppler].
Color flow images of hilar bile duct carcinoma and the relationship between tumors and hilar important blood vessals were observed in 22 patients with hilar bile duct carcinoma by color Doppler flow imaging (CDFI) and Duplex Doppler. It was found that most of bile duct carcinoma were of oligovascularity. Accurate rate were 81.82% and 77.28% respectively by preoperative ultrasound evaluation of the relationship between the tumor and the portal vein, and the tumor and the hepatic artery. CDFI and Duplex Doppler are sensitive, convenient and noninvasive methods for preoperative evaluation of resectability of hilar bile duct carcinoma and provide important information for surgery.
