肝癌合并下腔静脉癌栓的外科治疗

Surgical treatment of hepatocellular carcinoma combined with inferior vena cava tumor thrombosis

肝癌合并下腔静脉癌栓的治疗仍是医学难题,一直被视为手术禁忌证.患者主要接受非手术治疗或放弃治疗,其生存率较低.近年来随着医学的进步,手术治疗肝癌合并下腔静脉癌栓的成功率逐年增高.201 1年5月哈尔滨医科大学附属第二医院为1例肝癌合并下腔静脉癌栓患者行肝脏Ⅴ、Ⅶ、Ⅷ段切除＋下腔静脉癌栓取出术.术前CT检查示肝Ⅴ、Ⅶ、Ⅷ段占位性病变,下腔静脉内癌栓充盈,三维重建测算左半肝体积489 cm^3,低于最小存活肝脏体积.为了最大限度保留剩余肝脏,拟行保留肝Ⅵ段的右半肝切除术,于全肝血流阻断下腔静脉癌栓取出术.患者术后恢复良好,术后18个月复查未见明显复发转移症状.

Hepatocellular carcinoma （HCC） combined with inferior vena cava （IVC） tumor thrombosis is regarded unresectable.Most of the patients received non-surgical treatment or gave up treatment,and the prognosis of these patients is poor.As the development of surgical treatment,the success rate of surgical treatment for HCC combined with IVC tumor thrombosis is increasing yearly.In May of 2012,one patient with HCC combined with IVC tumor thrombosis received hepatic Ⅴ,Ⅶ and Ⅷ segmentectomy ＋ tumor thrombosis removal from the IVC at the Second Affiliated Hospital of Harbin Medical University.Preoperative computed tomography showed space-occupying lesions in the segments Ⅴ,Ⅶ and Ⅷ,and the IVC was filled with tumor thrombi.The volume of the left liver was 489 cm3,which was under the limit for survival.In order to preserve the remnant liver,right hepatectomy with reservation of hepatic segment Ⅵ,and the tumor thrombi in the IVC were removed with total hepatic vascular exclusion.The patient was recovered with no tumor recurrence or metastasis at postoperative month 18.
