Abstract
Objective
Toinvestigatetherelationshipbetweenopencollateralcirculationandcerebralmicrohemorrhageinpatientswithacutecerebralinfarction.
Methods
Atotalof184patientswithsevereunilateralcarotidarterystenosisorocclusionofacutecerebralinfarctiontreatedinLinfenCentralHospitalfromNovember2015toAugust2018wereselected.Allpatientsweredeterminedbydigitalsubtractionangiography.Accordingtocollateralcirculation,theyweredividedintogroup1(anteriorcommunicatingarteryopening),group2(posteriorcommunicatingarteryopening),andgroup3(non-anteriorandposteriorcommunicatingarteryopening).Thenumberofcerebralmicrohemorrhagesat6and12monthsofonsetwasdeterminedandanalyzedbymagneticresonanceimaging.
Results
At6monthsand12monthsofonset,newcerebralmicrohemorrhagesingroup1andingroup2weremainlydistributedinthesubcorticalareaandcorticalarea,andtheymainlydistributedinthebasalgangliaareaingroup3.At6monthsofonset,thenumbersofnewcerebralmicrohemorrhagesingroups1to3were18,12,and18,respectively,andthedifferencesamongthethreegroupswerenotsignificant(P>0.05).At12monthsofonset,thenumbersofnewcerebralmicrohemorrhagesingroups1to3were24,16,30,respectively;andthenumbersofnewcerebralmicrohemorrhagesingroup3wasmorethanthosethoseingroup1andingroup2(P<0.05),buttherewasnosignificantdifferencebetweengroup1andgroup2(P>0.05).Ingroup3,thenumbersofnewcerebralmicrohemorrhages12monthsafteronsetweresignificantlymorethanthat6monthsafteronset(P<0.05).
Conclusions
