摘要:

目的    总结变异脾动脉瘤的腔内治疗经验。方法    回顾性分析2007年4月至2017年4月复旦大学附属中山医院血管外科收治的15例变异脾动脉瘤腔内治疗病人的临床资料,其中5例为A型变异脾动脉瘤,10例为B型变异脾动脉瘤。结果    15例病人中14例腔内治疗成功,操作结束后造影检查示瘤体不再显影;1例术中造影检查后考虑弹簧栓栓塞后移位至肠系膜上动脉风险大且病人动脉瘤直径较小,遂停止手术并随访观察。14例腔内治疗成功的病人中,1例行单纯瘤腔栓塞,5例行出瘤动脉及瘤腔栓塞,1例行入瘤动脉、瘤腔及出瘤动脉栓塞,1例行瘤腔栓塞及肠系膜上动脉覆膜支架置入,2例行出瘤动脉栓塞及肠系膜上动脉覆膜支架置入,4例行出瘤动脉、瘤腔栓塞及肠系膜上动脉覆膜支架置入。随访2~117个月,无失访或死亡病例,无肠道缺血坏死、症状性脾梗死、动脉瘤破裂等严重并发症发生。1例病人7年后再发腹痛,再次腔内治疗行瘤腔密集填塞,术后腹痛消失,密切随访。1例病人腔内治疗行出瘤动脉栓塞及肠系膜上动脉覆膜支架置入,术后第2年随访动脉造影检查示覆膜支架完全闭塞,Riolan弓显影,支架远端肠系膜上动脉灌注良好。结论    腔内治疗变异脾动脉瘤安全、有效。在腔内治疗过程中,除了对动脉瘤完成满意的血流隔绝,还应重视保护肠系膜上动脉。

Abstract    Objective    To summarize the endovascular treatment experience of aberrant splenic artery aneurysms. Methods    The clinical data of 15 aberrant splenic artery aneurysms including 5 type A and 10 type B aneurysms treated by endovascular repair in Zhongshan Hospital,Fudan University from April 2007 to April 2017 was retrospectively analyzed. Results    Technical success was achieved in 14 of 15 patients with angiographic documentation of aneurysmal exclusion. Endovascular treatment was abandoned after considering the high risk of coil embolization into the superior mesenteric artery and the relatively small aneurysm size in one patient. Treatment strategies of aberrant splenic artery aneurysms included coil embolization of the sac and outflow artery,with or without embolization of the inflow artery,or covered stent placement in the superior mesenteric artery. Follow-up time ranged from 2 to 117 months. No hepatic or intestinal ischemia,or death developed perioperatively or during the follow-up period. Reintervention was needed in 1 patient for persistent sac enlargement. The covered stent was found asymptomatically occluded in 1 patient at 2 years because of abundant collateral perfusion of the Riolan’s arch. Conclusion    Endovascular treatment appeared to be feasible,safe,and effective in the management of aberrant splenic artery aneurysms. Furthermore,the preservation of the superior mesenteric artery,should be emphasized when optimizing aneurysmal exclusion.
