【摘要】 目的　分析肝内胆管细胞癌DSA征象并探讨其病理基础。方法　 16例肝内胆管细胞癌行选择性肝动脉DSA检查 ,5例手术和 11例穿刺活检病理证实诊断。结果　 13例DSA表现为肿瘤血管呈“网格状”或“羽毛状” ,肿瘤染色轻至中度 ,边界不清 ;3例肿瘤血管稀少 ,染色淡而迟。病理所见 :肿瘤细胞簇状排列 ,间质纤维丰富 ,血管分布稀疏。结论　肝内胆管细胞癌DSA表现“网格状”和“羽毛状”颇具特征 ,对肝内胆管癌有较大诊断价值更多还原

【Abstract】 Objective To analyze the DSA findings and pathologic basis of intrahepatic cholangiocarcinoma.Methods Selective hepatic artery arteriography were performed in sixrteen patients with intrahepatic cholangiocarcinoma proven pathologically. Results Tumor vascular plexus presented as "feathery" and "networks" were shown during arterial period and with light or moderate staining in 13 patients. Tumor vessels were rare and staining delayed in three cases. Pathologically:the tumor cells were plexiform distribution,interstitial fibrosis was plenty and the blood vessels were rare.Conclusion The findings of feathery sign and network sign on DSA are of important value in a diagnosis of intrahpatic cholangiocarcinoma.更多还原
