Abstract:
Objective To investigate the risk factors and MRA manifests in the patients with cortical wa-tershed infarcts(CWSI)or internal watershed infarcts(IWSI).Methods We collected the patients with acute wa-tershed infarcts in our hospital from January 2013 to April 2016.According to the Bogousslavsky classification stan-dard,the patients were divided into two groups:CWSI and IWSI. The two groups were compared in terms of risk factors and MRA manifests. Results We included 36 CWSI and 11 IWSI patients in the study.There were signifi-cant differences in smoke,diabetes mellitus,fasting blood glucose levels and carotid atherosclerotic plaque be-tween the two groups,and so it was with the stenosis of ICA,MCA,ACA,PCA,VA and BA:The stenosis of ICA in the CWSI group was more serious than in the IWSI group,but the stenosis of MCA,ACA,PCA,VA and BA in the IWSI group was more serious than in the CWSI group. Conclusions The pathogenesis of CWSI may be related to the formation of carotid atherosclerotic plaques,carotid stenosis and arterial artery embolism,or plaque shedding and micro emboli removal.The pathogenesis of IWSI may be related to the decrease of the perfusion pres-sure at the end of the intracranial artery.The ratio of IWSI to diabetes mellitus is higher than that of CWSI,suggest-ing that the damage of diabetes to intracranial arteriole is earlier than that of intracranial and extracranial arteries.
