摘要
作者应用彩色多普勒血流显象和双功能超声对２２例肝门部胆管癌的供血特点以及肿瘸与肝门部重要血管间的关系进行了观察。结果表明：肝门部胆管癌多为少供血肿瘤。与手术结果对比分析，术前超声在判定肿瘤与门静脉关系上，诊断符合率为８１．８２％；肿瘤与肝动脉关系上诊断符合率为７７．２８％。作者认为彩色多普勒血流显象和双功能超声只有诊断符合率高，操作简单，无放射性损伤等特点，应用此项技术术前可以评估肝门部胆管癌的浸润程度及手术切除的可行性，为临床外科提供了重要的帮助。
Abstract Color flow images of hilar bile duct carcinoma andthe relationship between tumors and hilar importantHood vcssals were observed in 22 patients with hilarbile duct carcinoma by color Doppler flow imaging(CDFI)and Duplex Doppler. It was found that mostof bile duct carcinoma were of oligovascularity. Accu-rate rate were 81. 82%and 77. 28%repectively by pre-operative ultrasound evaluation of the relationship be-tween thetumor and the portal vein, and the tumor and the hepatic artery, CDFI and Duplex Dopplex are sensitive,convenient and noninvasive methods for pre-operative evaluatiort of resectability of hilar bile duct carcinoma and provide important information forsurgery.
