腹主动脉瘤合并消化系统恶性肿瘤的外科治疗

目的 探讨腹主动脉瘤腔内隔绝术在腹主动脉瘤合并消化系统恶性肿瘤患者治疗中的可行性。方法 回顾性分析2014年1月至2019年12月在北京协和医院接受治疗的28例腹主动脉瘤合并消化系统恶性肿瘤患者的临床资料及随访结果。结果 28例患者中,合并结直肠癌21例,胃癌6例,肝癌1例。所有患者均采取分期手术治疗,其中21例选择先行腹主动脉瘤腔内隔绝术,2期行肿瘤手术。所有患者术后恢复良好,无围手术期死亡,无动脉瘤破裂、肠缺血、肠瘘等并发症。出院后随访过程中1例患者出现支架内血栓形成,1例存在Ⅱ型内漏,无腹主动脉瘤相关性死亡。结论 腹主动脉瘤腔内隔绝术由于微创、不改变腹腔内解剖结构等特点,缩短了分期手术时间间隔,降低了消化系统肿瘤手术难度,是治疗方案中值得推荐的方法。

Treatment of Concomitant Intra-abdominal Malignancy and Abdominal Aortic Aneurysm

Objective To explore the outcomes in patients who receive the endovascular abdominal aortic aneurysm repair(EVAR)and have concomitant intra-abdominal malignancy.Methods Between January 2014 and December 2019,all the patients who underwent surgery for malignancy and/or EVAR were retrospectively reviewed.Results Twenty-eight abdominal aortic aneurysm(AAA)patients with concomitant intra-abdominal malignancy were included.The patients were treated by two-stage operation and the priority was given for EVAR in 21 patients.There was no perioperative death or major complications.In the follow-up,one patient developed graft thrombosis and one had type Ⅱ endoleak.There was no AAA-associated death.Conclusions It is preferred that EVAR should come first followed by operation for malignancy.Details of treatment strategy still need further investigation.
