Kurzfassung:
Omental artery aneurysm (OAA) is an extremely rare visceral artery aneurysm. Ruptured OAAs are associated with a high mortality rate. Transcatheter arterial embolization (TAE) has been used to treat OAA in recent years. However, the risk of omental ischemia due to TAE remains unclear. Therefore, this study aimed to investigate the efficacy and safety of TAE of OAA as a first-line treatment. 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. Conclusion The OAA-TAE can effectively treat ruptured and unruptured OAAs, and the risk of omental infarction after OAA-TAE may not be high.
