Aneurysms were located in the anterior communicating artery (75%), middle cerebral artery (17%), and basilar artery (8%). All patients received dual antiplatelet therapy for ten days pre-procedure and 6\u00a0months post-procedure, followed by aspirin monotherapy. The O\u2019Kelly-Marotta (OKM) scale was used to assess aneurysm filling, where Grade D indicates complete occlusion. Clinical outcomes were measured using the modified Rankin Scale (mRS), with scores of 0\u20131 reflecting no or minimal disability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      At the end of the procedure, 75% (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 9) of patients exhibited stagnant contrast filling within the aneurysm sac (OKM Grade C) during the venous phase.
