Transarterial chemoembolization is standard treatment for unresectable hepatocellular carcinoma. Prophylactic embolization of variant hepatic or gastric arteries before treatment of liver tumors reduces inadvertent injury to adjacent organs. This report presents a patient with multiple hepatocellular carcinomas, who developed an episode of acute gastric ulcer bleeding because of coil migration into the stomach 2 years after prophylactic embolization of the accessory right gastric artery for transarterial chemoembolization. This report discusses the purpose of prophylactic embolization, complications of coil embolization, various presentations and possible mechanisms of coil migration, and treatment of gastrointestinal bleeding. It also reviews pertinent literature.
经动脉化疗栓塞术是不可切除肝细胞癌的标准治疗方法。在治疗肝肿瘤之前预防性栓塞变异肝或胃动脉可减少对邻近器官的意外伤害。本报告介绍了一位患有多个肝细胞癌的患者，他在接受经动脉化疗栓塞术的辅助右胃动脉预防性栓塞 2 年后，因线圈迁移至胃部而发生急性胃溃疡出血。本报告讨论了预防性栓塞的目的、线圈栓塞的并发症、线圈迁移的各种表现和可能的机制，以及胃肠道出血的治疗方法。还回顾了相关文献。
