Abstract：Objective To investigate the efficacy and safety of the Pipeline embolization device(PED)versus stent-assisted coiling(SAC)in the treatment of unruptured intracranial aneurysms.Methods Clinical and follow-up data of 32 patients with unruptured intracranial aneurysms who underwent PED or SAC treatment from January 2019 to December 2024 were collected,including age,aneurysm characteristics,treatment process,postoperative complications and follow-up outcomes,with no statistically significant difference in baseline data between the two groups(P>0.05).Statistical analysis was performed to compare the therapeutic efficacy and safety between the two groups.Results The incidence of postoperative complications was 0 in the PED group and 3.1%in the SAC group,showing no statistically significant difference(P>0.05).The PED group had shorter operation time,lower postoperative aneurysm recurrence rate,higher incidence of postoperative in-stent stenosis and better neurological function recovery,with all differences statistically significant(P<0.05).Conclusions In the endovascular treatment of unruptured intracranial aneurysms,compared with stent-assisted coiling,Pipeline embolization device has the advantages of shorter operation time,lower aneurysm recurrence rate and better postoperative neurological function recovery,but it is associated with a higher incidence of postoperative parent artery stenosis.
