目的 应用彩色多普勒血流显像(CDFI)及脉冲多普勒(PD)检测门静脉癌栓的血流状况。方法 运用CDFI和PD检测门静脉癌栓及其周围有无血流信号,在血流信号明显处取样,获得PD血流频谱。结果 31例癌栓内见稀疏星点状血流信号,无血流频谱,5例癌栓内可探及动脉血流频谱。结论 CDFI和PD具有无创、可重复动态观察的优点,是临床诊断及治疗方案选择不可缺少的重要手段和方法。
Objective To detect the blood flow status of portal vein tumor emboli using color Doppler flow imaging (CDFI) and pulsed Doppler (PD). Methods CDFI and PD were used to detect portal vein tumor emboli and its surrounding blood flow signals. Blood flow signal was sampled to obtain PD blood flow spectrum. RESULTS: Sparse star-shaped blood flow signals were observed in 31 cases of tumor thrombus. There was no blood flow spectrum, and the spectrum of arterial blood flow was detectable in 5 cases of tumor emboli. Conclusion CDFI and PD have the advantages of non-invasive and repeatable dynamic observation. They are indispensable important methods and methods for clinical diagnosis and treatment plan selection.
