Endovascular therapy achieved primary technical success in 88.5% of cases. Two patients failed endovascular access via both the CA and SMA. Another had a vascular variant creating a high risk of splenic ischemia upon embolization, and a fourth had an aneurysm involving critical duodenal branches. Three of these four patients underwent successful open surgical repair. Sac-only embolization was performed in 63.6% of cases to preserve collateral flow. Access routes were largely determined by aneurysm location, with SMA for SMA-IPDA aneurysms and celiac artery (CA) for GDA-SPDA aneurysms (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009&lt;\u20090.001). Concomitant celiac revascularization was avoided in most cases.
