右肝动脉(RHA)较其它部分肝动脉更易受到胆管肿瘤的侵及。术前对RHA受累情况作出准确判断,对于有望实施手术切除的胆管癌患者是非常重要的。在本研究中,作者对彩色多普勒超声(CDUS)诊断胆管癌患者RHA受累的准确性进行了评价,并与B型超声(BUS)、CT及血管造影作了比较。 在1990年8月至1995年12月间对19例肝外胆管癌和4例胆囊癌患者的RHA受累情况进行了检测。11例手术切除,2例做了姑息手术。13例手术患者由组织病理学证实了胆管癌的诊断,未手术者9例由胆汁细胞学证实,1例由细针活检证实。所有患者均行BUS、CDUS、CT及腹部血管造影检查。在用BUS和
The right hepatic artery (RHA) is more susceptible to invasion of bile duct tumors than other parts of the hepatic artery. Accurate judgment of the condition of RHA involvement before surgery is very important for patients with cholangiocarcinoma who are expected to undergo surgical resection. In this study, the authors evaluated the accuracy of color Doppler ultrasound (CDUS) diagnosis of RHA involvement in patients with cholangiocarcinoma, and compared them with B-mode ultrasound (BUS), CT, and angiography. Between August 1990 and December 1995, 19 patients with extrahepatic cholangiocarcinoma and 4 patients with gallbladder cancer were tested for RHA involvement. Eleven patients underwent surgical resection and 2 patients underwent palliative surgery. The diagnosis of cholangiocarcinoma was confirmed by histopathology in 13 surgical patients. Nine cases of unoperated patients were confirmed by bile cytology, and one case was confirmed by fine-needle biopsy. All patients underwent BUS, CDUS, CT, and abdominal angiography. With BUS and
