本文应用彩色多普勒血流显像观察肝癌肝动脉栓塞（ＴＡＥ）及肝动脉和门静脉双重栓塞（ＴＡＥ＋ＰＶＥ）治疗前后肿瘤血供和声像图的变化以及二者之间的关系。结果显示ＴＡＥ后，肿瘤门静脉供血从２０．９％增加到５５．６％。在ＴＡＥ基础上行ＰＶＥ治疗，使肿瘤动脉供血和门静脉供血均明显减少。肝癌化疗栓塞后肿瘤缩小程度与血供减少程度密切相关。经双重栓塞治疗的肝癌患者临床预后优于单纯经ＴＡＥ治疗者。结果表明彩色多普勒超声在指导临床介入件治疗药物用量和评价介入性治疗效果起重要作用。
In this study, color Doppler flow imaging was used to observe the changes in blood supply and sonogram before and after hepatic arterial embolization (TAE), hepatic artery and portal vein double embolization (TAE+PVE), and the relationship between them. The results showed that after TAE, portal vein blood supply increased from 20.9% to 55.6%. Upward PVE treatment on the basis of TAE significantly reduced both arterial blood supply and portal vein blood supply to tumors. The degree of tumor shrinkage after liver cancer chemoembolization is closely related to the degree of blood supply reduction. The clinical prognosis of liver cancer patients treated with dual embolization was better than those treated with TAE alone. The results showed that color Doppler ultrasound plays an important role in guiding clinical interventional components in the treatment of drug use and evaluation of interventional treatment.
