目的 :探讨超声引导下门脉癌栓穿刺注射结合高频聚焦超声 (HIFU)技术治疗门脉癌栓的安全性和有效性。方法 :8例合并门脉主支癌栓的原发性肝癌患者在超声引导下穿刺在癌栓内注入碘油化疗药物混悬液并接受 HIFU治疗。结果 :1例患者出现肠系膜上静脉异位栓塞 ,无其它相关并发症出现 ,X-线摄片示门脉癌栓内碘油致密沉积 ,MRI或 CT检查示门脉癌栓血供消失 ,随访 4例患者门脉癌栓缩小或消失。结论 :超声引导下门脉癌栓内药物注射结合 HIFU技术是一种安全和有效治疗门脉癌栓的方法
Objective: To investigate the safety and efficacy of ultrasound guided portal vein tumor thrombus puncture injection combined with high frequency focused ultrasound (HIFU) in the treatment of portal vein tumor thrombus. Methods: Eight patients with primary liver cancer with portal vein tumor thrombus were injected with lipiodol drug suspension and received HIFU treatment under ultrasound-guided puncture. RESULTS: One patient had ectopic embolization of the superior mesenteric vein and no other complications occurred. X-ray showed dense lipiodol deposition in portal vein tumor thrombus, and disappearance of portal vein tumor thrombus by MRI or CT. Follow-up 4 patients with portal vein thrombosis or disappear. Conclusion: Ultrasound-guided intracapsular injection of drug in combination with HIFU is a safe and effective method for the treatment of portal vein tumor thrombus
