原发性肝癌合并门静脉癌栓的介入治疗进展

门静脉癌栓是导致肝癌远处转移及术后复发的重要因素之一，严重影响肝癌患者预后。针对门静脉癌栓，目前仍缺乏有效手段，介入治疗以其微创、可重复性等优点存临床得到广泛应用．并取得一定的疗效。目前主要应用的介入治疗方法包括：绎导管动脉灌注化疗术、经导管动脉化疗栓塞术、肝动脉、门静脉双途径化疗栓塞术、无水酒精注射术、门静脉支架置放术和超声消融术，多种方法联合治疗有望取得较好疗效。

The Progress of Interventional Therapy for Hepatocellular Carcinoma with Portal Vein Tumor Thrombus

Portal vein tumor thrombus(PVTT)is one of the most important factors resulting in remote metastasis and post-operation recurrence,and make severe influence on the poor prognosis of patients with hepatocellular carcinoma(HCC).There aren't effective treatments for PVTT,interventional therapy are widely used in clinic because of its minimally invasive and repeatable characteristics,and has showed certain efficacy.Transcatheter arterial chemo-infusion(TAI),transcatheter arterial chemo-embolization(TACE),dual intervention TACE,percutaneous ethanol injection,portal vein stent placement and ultrasound-mediated disruption are commonly used therapies and the multiple therapeutic courses may be useful to achieve favorable results.
