Embolization techniques included sac packing, trapping, combined approaches, and stent-graft placement.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Technical success was achieved in all 66 cases. Clinical success was obtained in 94.1% of evaluable patients, with two cases of recanalization and one new aneurysm detected during follow-up. Splenic infarction occurred in 24 patients (37.5%) and was associated with distal or hilar\/intrasplenic location (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.007), larger pre-embolization splenic volume (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.018), and reduced splenic staining on angiography after embolization (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&amp;lt;\u20090.001). In multivariate analysis, only reduced splenic staining on angiography remained an independent predictor of infarction (HR\u2009=\u20090.939;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.001). Among infarcted patients, 12 (50%) demonstrated regeneration and 12 (50%) progressed to atrophy, with regeneration associated with higher post-embolization splenic staining on angiography (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.036), smaller infarcted volume (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.003), and greater final splenic volume (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.018). Overall complication rate was 39.1%, all of which resolved with conservative management.
