经导管栓塞术治疗急性重症胰腺炎并发假性动脉瘤

目的 评价经导管栓塞术治疗急性重症胰腺炎并发假性动脉瘤的价值。方法 7例急性重症胰腺炎并发腹部假性动脉瘤患者进行了腹部动脉造影及经导管栓塞治疗，观察假性动脉瘤出现的部位、术中及术后并发症、再出血情况及临床结果。结果 造影共发现假性动脉瘤7例，位于脾动脉5例、胃网膜右动脉1例和胃左动脉1例，3例动脉瘤见活动性出血征象。6例动脉瘤用弹簧圈栓塞载瘤动脉，出血立即停止，其中5例1次栓塞成功，1例经2次栓塞成功。3例再次出血，再出血时间为14～60d，1例再次造影发现脾动脉假性动脉瘤形成，弹簧圈栓塞后出血停止，2例再次造影均未见明显出血原因，死亡。1例用明胶海绵颗粒栓塞无效，3d后出血死亡。2例发生与插管和造影操作相关的并发症，1例为动脉破裂，1例为动脉内膜夹层。无严重术后并发症发生。结论 经导管栓塞术治疗急性重症胰腺炎并发假性动脉瘤是1种有效和相对安全的方法。

Transcatheter embolization of pseudoaneurysms complicating acute severe pancreatitis

Objective To evaluate the therapeutic roles of transcatheter embolization in patients with pseudoaneurysms complicating acute severe pancreatitis. Methods Seven patients who suffered from pseudoaneurysms complicating acute severe pancreatitis received abdominal angiography and were treated with transcatheter embolization. The angiographic findings, complications related to the procedure and post-embolization, and rebleeding were observed. Results The pseudoaneurysms developed at the splenic artery (n=5), right gastroepiploic artery (n=1), and left gastric artery (n=1), respectively. Findings of active bleeding were observed in 3 patients. Six of them were embolized with coils, and the bleedings were stopped immediately. Rebleeding occurred 14-60 days after the embolization in 3 patients, and in one of them, another pseudoaneurysm was observed in repeated angiography and was successfully treated by repeated embolization. No causes of bleeding were found in repeated angiography in the other 2 patients, who died from severe hemorrhage. One pseudoaneurysm was embolized with gelfoam granule. The gastrointestinal bleeding was not controlled and the patient died 3 days later. Procedure related complications occurred in 2 patients. One was celiac trunk rupture during angiography, the other was intima dissecting in splenic artery. Severe post procedure complications occurred in none of the patients. Conclusion Transcatheter embolization is safe and relatively effective in the management of pseudoaneurysms complicating acute severe pancreatitis.
