彩色多普勒诊断原发性肝癌并门静脉癌栓

目的：探讨原发性肝癌合并门静脉癌栓的彩色多普勒特点及诊断价值。方法：应用Philips HDII彩色超声诊断仪对34例原发性肝癌合并门静脉癌栓的血流特征进行回顾性分析。结果：根据门静脉癌栓内部及周边血流信号的彩色多普勒状况,分为4种情况：①癌栓内无血流信号;②癌栓内有少许血流信号;③门静脉癌栓周围出现动静脉瘘;④癌栓与管壁之间出现动脉血流。结论：原发性肝癌合并门静脉癌栓有其门静脉及肝动脉血流动力学的特殊变化,对区分原发性肝癌和继发性肝癌有较重要的临床价值。

Ultrasonic diagnosis of portal vein tumor thrombus in primary hepatic carcinoma

Objective:To explore the sonographic characteristics and their diagnostic value of color Doppler flow imaging in primary hepatic carcinoma with portal vein tumor thrombus.Methods:The data of 34 cases of primary hepatic carcinoma with portal vein tumor thrombus were retrospectively analyzed.Results: According to the blood flow signals of portal vein tumor thrombus,the imaging findings were divided into four types: thrombus without blood flow signals,thrombus with a few flow signals,arteriovenous fistula form...
