Objective To explor the relationship between the different types of perforating artery fresh infarcts of the middle cerebral artery and related arterial stenosis.Methods All 152 acute ischemic stroke patients hospitalized in our hospital from February 2007 to April 2009 were retrospectively reviewed.Lesions of middle cerebral artery were classified on diffusion weighted imaging (DWI) as small perforator infarcts (small PAI,diameter≤3.20 cm),large perforator infarcts (large PAI,diameter >3.20 cm),concomitant perforator and pial infarcts (PAI + PI),concomitant perforator and border-zone infarcts (PAI +BZ),concomitant perforator,pial and border-zone infarcts (PAI + PI + BZ).The percentages of arterial stenosis and the severity of arterial stenosis or arterial occlusion were analyzed in each group and compared among each group.Results Arterial stenosis was 16/87,9/11,17/17,11/12,23/25 in the group of small PAI,large PAI,PAI + PI,PAI + BZ,PAI + PI + BZ,respectively.There was significant difference between small PAI group and other four groups (χ~2 =21.780,48.065,30.567,55.523,P=0.000);the arterial severe stenosis or arterial occlusion were 1/87,2/11,12/17,9/12,21/25 in each groups,and there was significant difference between small PAI group and other groups (χ~2 =56.505,55.465,79.283,P = 0.000),between large PAI group and other groups (χ~2= 7.337,7.425,11.633,P = 0.007,0.006,0.001).There was no significant difference between infarcts of bigger than 2.00 cm but smaller than 3.20 cm and infarcts smaller than 2.00 cm (χ~2 = 0.253,P = 0.615).Conclusion The small PAI group had a lower percentage of arterial stenosi,and lower percentage of severe arterial stenosis or arterial occlusion.The large PAI group,PAI + PI group,PAI + BZ group and PAI+ PI + BZ group had higher percentages of arterial stenosis.The PAI + PI group,PAI+ BI group and PAI+ PI + BZ group had higher percentages of severe arterial stenosis or arterial occlusion.
