Jejunal artery aneurysms are extremely rare; only 58 cases have been reported up to 2022. The high rupture rate necessitates a curative treatment. Only four cases of true jejunal artery aneurysms treated with endovascular embolization were reported. We report a case of a 75-year-old man with a true jejunal artery aneurysm who was successfully treated with endovascular embolization. The aneurysm was located in the third jejunal branch. The proximal and distal distance to the superior mesenteric artery and the first bifurcation of the third jejunal branch, respectively, were too short to perform isolation. First, we performed packing in the aneurysm, followed by secondary parent artery embolization. Finally, we achieved total occlusion of the aneurysm and its parent artery with preserved distal intestinal blood flow.
空肠动脉动脉瘤极为罕见；截至2022年，仅报告了58例。由于其高破裂率，需要进行根治性治疗。仅有4例真正的空肠动脉动脉瘤采用血管内栓塞治疗的病例报告。我们报告一例75岁男性真正的空肠动脉动脉瘤，经血管内栓塞成功治疗。动脉瘤位于空肠第三分支。分别与肠系膜上动脉和空肠第三分支第一分叉处的近端和远端距离过短，无法进行隔离。首先，我们对动脉瘤进行填塞，随后对供血动脉进行二期栓塞。最后，我们实现了动脉瘤及其供血动脉的完全闭塞，同时保留了远端肠道血流。
