目前,手术切除部分肝叶仍然是治疗肝脏原发性或转移性恶性肿瘤首选和最有效的方法,然而术后残余肝脏容积不足容易发生肝衰竭,影响预后。选择性门静脉栓塞术通过栓塞荷瘤侧门静脉分支,从而使门静脉血流重分配,增加对侧肝组织的门静脉血流,来增加余留肝脏体积。综述了选择性门静脉栓塞术的理论基础及其在临床中的应用,作为肝切除术前的辅助治疗方法,降低术后肝衰竭发生率,提高肿瘤切除率和手术的安全性,使原来无法行手术治疗的患者得到了手术的机会。
At present, the surgical removal of some of the liver lobe is still the treatment of primary or metastatic liver cancer of choice and the most effective method, however, insufficient liver volume after liver failure prone to affect the prognosis. Selective portal vein embolization by embolization of tumor side portal vein branch, so that portal vein redistribution, increase the contralateral liver tissue portal vein blood flow, to increase the remaining liver volume. This review summarizes the theoretical basis of selective portal vein embolization and its clinical application, as an adjuvant therapy before hepatectomy to reduce the incidence of postoperative liver failure and improve the tumor resection rate and surgical safety, so that the original can not be done Surgery patients get the chance of surgery.
