Abstract：Endosaccular flow diverters representanovel categoryof endovascular interventionaldevices primarily employed for the treatmentof intracranial wide-neckand bifurcationaneurysms.Conventionalcoil embolization faces challngessuch ascoil prolapseandrecurrence inwide-neck or bifurcationaneurysms，whileflowdivertersare limitedbycomplexdeployment proceduresand potential compromiseof bloodflowinbranch vessels.Endosaccular flowdiverters area novel interventional embolization device that changes thehemodynamicswithin the aneurysm, promotes thrombus formation，and provides metal coverageatthe neck of theaneurysm to promote endothelialization. Currently，multipleendosaccularflow divertersareunder clinicaluseorinvestigation worldwide.Among these，only theWoven EndoBridge(WEB）devicehasreceivedFDAapproval intheUnited States，whileothersrequire further validation through multicenter studies withlarge-samplefollow-up data.This review summarizesthe structural characteristics，clinical applications，and research advancements of current endosaccular flow diverters.

血管内治疗已成为未破裂动脉瘤患者最主要的治疗方法，但在宽颈或分叉部的动脉瘤中单纯使用弹簧圈栓塞存在无法稳定填充导致弹簧圈易逸出和瘤颈弹簧圈被血流冲击压缩导致复发等问题[1]。（剩余16720字）
