METHODS: Fifteen patients with true aneurysms or pseudoaneurysms who underwent OAA-TAE between 1 April 2010 and 31 December 2022 were included in this study. The technical and clinical outcomes, the incidence of omental infarction after TAE as a major complication, OAA-TAE techniques, radiological findings on computed tomography angiography and angiogram, and patient characteristics were evaluated.
RESULTS: Fifteen patients (nine men, six women; age, 69.8 ± 18.59 years) underwent TAE of OAAs (mean aneurysm size of 9.30 ± 6.10 mm) located in the right gastroepiploic (n = 9), left gastroepiploic (n = 1), and epiploic (n = 5) arteries. All patients with ruptured (n = 6) and unruptured (n = 9) OAA successfully underwent TAEs using coils, n-butyl-2-cyanoacrylate, or gelatin sponges. Hepatic artery thrombosis and coil migration were observed during the procedure; however, these adverse events were manageable. Transfusion of red blood cell units (4.66 ± 1.63 units) was required only in cases with ruptured OAAs after TAE. Additional surgery or TAE due to rupture or rerupture of OAA and omental infarction was not required during the postoperative and follow-up periods.
CONCLUSIONS: The OAA-TAE can effectively treat ruptured and unruptured OAAs, and the risk of omental infarction after OAA-TAE may not be high.
方法:本研究纳入了在2010年4月1日至2022年12月31日期间接受OAA-TAE的15例真实动脉瘤或假性动脉瘤患者。技术和临床结果,TAE后网膜梗死的发生率为主要并发症,OAA-TAE技术,计算机断层扫描血管造影和血管造影的放射学发现,和患者特征进行了评估。
结果:15名患者(9名男性,六个女人;年龄,69.8±18.59年)接受了位于右侧胃表皮(n=9)的OAAs的TAE(平均动脉瘤大小为9.30±6.10mm),左胃上皮细胞(n=1),和表皮(n=5)动脉。所有OAA破裂(n=6)和未破裂(n=9)的患者使用线圈成功接受了TAEs,2-氰基丙烯酸正丁酯,或明胶海绵。术中观察到肝动脉血栓形成和线圈迁移;然而,这些不良事件是可控的.仅在TAE后OAAs破裂的情况下才需要输注红细胞单位(4.66±1.63单位)。在术后和随访期间,不需要因OAA破裂或再破裂和网膜梗塞而进行其他手术或TAE。
结论:OAA-TAE可以有效治疗破裂和未破裂的OAA,OAA-TAE后发生网膜梗死的风险可能不高。
