Background　and　Objectives:　Intraoperative　aneurysm　rupture　(IOR)　is　a　difficult　event　during　the　clipping　process　for　intracranial　aneurysms,　and　could　result　in　a　bad　prognosis.　Preoperative　discrimination　of　aneurysms　with　high　risk　of　IOR　is　vital　for　operators.　The　aim　of　this　study　was　to　explore　the　hemodynamic-morphological　risk　factors　for　the　IOR.　Methods:　In　the　present　study,　patients　admitted　for　unruptured　IA　from　January　2012　to　April　2018　were　retrospectively　reviewed.　A　propensity　score　matching　was　performed　to　match　patients.　The　morphological　features　and　the　hemodynamic　features　were　extracted.　Differences　in　the　morphologic　and　hemodynamic　parameters　were　compared.　Risk　factors　associated　with　IOR　were　explored.　Subsequently,　the　hemodynamic　characteristics　in　different　rupture　stages　and　different　regions　in　IOR　aneurysm　were　compared.　Results:　96　cases　of　patients　with　aneurysms,　were　found　by　the　matching　process　in　each　group.　The　statistically　significant　difference　was　found　in　the　maximum　length　(L)　(p　=　0.041),　maximum　diameter　of　body　(D)　(p　=　0.032),　aspect　ratio　(AR)　(p　＜　0.001),　non-sphericity　index　(NSI)　(p　＜　0.001),　normalized　wall　shear　stress　maximum　(NWSSm)　(p　＜　0.001)　and　oscillatory　shear　index　(OSI)　(p　＜　0.001).　A　regression　analysis　demonstrated　AR　(OR　=　7.03,　p　＜　0.001),　NWSSm　(OR　=　15.55,　p　=　0.014)　and　OSI　(OR　=　28.30,　p　＜　0.001)　as　the　independent　risk　factors　for　IOR.　AR　was　much　larger,　and　NWSSm　and　NWSSa　were　much　lower　for　IAs　that　ruptured　in　early　or　predissection　stage　than　those　for　IAs　that　ruptured　in　dissection　stage　or　clip　application　stage.　NWSSa　and　NWSSm　in　rupture　area　were　both　lower　than　those　in　adjacent　area.　Conclusion:　AR,　NWSSm,　and　OSI　are　considered　three　independent　risk　factors　for　intraoperative　aneurysm　rupture,　which　could　serve　as　predictors.　A　selection　of　intervention　methods　for　aneurysms　with　high　AR,　low　NWSSm,　and　high　OSI　should　carefully　be　considered.
