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、可重复性等优点在临床得到广泛应用,并取得一定的疗效。目前主要应用的介入治疗方法包括:经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。
Portal vein tumor thrombosis is one of the important factors that lead to distant metastasis and postoperative recurrence of liver cancer, which seriously affects the prognosis of patients with liver cancer. For portal vein tumor thrombus, there is still no effective means. Interventional treatment has been widely used in clinic for its advantages of minimally invasive and reproducible, and has obtained certain curative effect. At present, the main interventional treatment methods include: transcatheter arterial infusion chemotherapy, transcatheter arterial chemoembolization, hepatic artery, portal vein chemoembolization, alcohol injection, portal stenting, and ultrasound ablation. Combination therapy is expected to achieve better results.
