摘要
目的 总结肠系膜上动脉瘤（SMAA）的诊治经验。 方法 本研究为回顾性纵向研究。回顾性分析2015年1月至2023年1月北京友谊医院和北京医院两个中心的6例SMAA患者的临床资料，其中4例为真性动脉瘤，包括肠系膜上动脉（SMA）主干动脉瘤2例及SMA分支动脉瘤2例；另2例为肠系膜上动脉夹层动脉瘤。所有患者均通过盆腹腔增强CT确诊，其中腹痛4例，均为脐周隐痛。SMAA瘤体直径为（25.0±3.7）mm。总结分析患者的病因、发病特点、影像学表现、解剖特点及治疗方法等。 结果 6例患者中，2例分支动脉SMAA，其中1例保守治疗，另1例行瘤体弹簧圈栓塞术治疗；2例主干SMAA，行SMAA切除加人工血管重建及SMAA成形术及肝总动脉-SMA自体大隐静脉重建；另2例夹层动脉瘤，其中1例行假腔弹簧圈栓塞及真腔支架重塑，1例行两层裸支架植入。4例腹痛患者术后症状缓解。随访时间为（19.1±5.2）个月，随访期内复查CT血管造影可见SMA支架、人工血管及自体静脉桥均通畅，无再发SMAA。 结论 症状性SMAA且直径超过2 cm，应积极手术干预，但具体的手术方法应根据SMAA的解剖部位及交通动脉的评估而定。 Objective To investigate the diagnosis and treatment of superior mesenteric artery aneurysm (SMAA). Methods This study was a retrospective longitudinal study. A total of 6 cases with SMAA from two centers, Beijing Friendship Hospital and Beijing Hospital were retrospectively reviewed from January 2015 to January 2023. Among the six patients, 4 cases had true aneurysms, including superior mesenteric artery (SMA) trunk aneurysm and SMA branch aneurysm, and the other 2 cases were SMA dissecting aneurysms. All patients were confirmed by the enhanced computed tomography (CT) of the abdomen and pelvis. Four patients (66.7%, 4/6) had abdominal pain, all of which were periumbilical pain. The mean diameter of SMAA was (25.0±3.7) mm. The clinical data were analyzed, including etiology, pathogenesis, imaging findings, anatomical location of the aneurysms, and their treatment methods. Results Among the 6 patients, 2 patients with SMAA on the branch underwent conservation treatment in 1 case and spring coil embolization in 1 case 2 patients with SMAA on the main trunk underwent SMAA resection, artificial vessel reconstruction, and the reconstruction of hepatic artery-SMA with autologous great saphenous vein besides, in 2 cases with SMA dissecting aneurysms, 1 case was embolized with spring coils at the false cavity and remodeled with a true cavity stent, and the other one was implanted with double-layer bare stents. Abdominal pain relieved in 4 patients postoperative. The follow-up time was (19.1±5.2) months, which reported no recurrence of SMAA in patients after surgery, according to the CT. The SMA stents, artificial blood vessels, and autologous vein bypass featured patency. Conclusion Symptomatic SMAA with a diameter of more than 2 cm should be actively treated with surgical or endovascular intervention, but the optimal method depends on the anatomical site and the evaluation of communicating arteries of SMAA.
