Abstract：Objective To investigate the etiology and clinical features for cortical watershed infarction ( CWSI ) and internal watershed infarction (IWSI).Methods Patients with cerebral watershed infarction (WSI) were recruited from October 2012 to May 2014 in the department of neurology of Aerospace Center Hospital ( Aerospace Clinical Medical Col-lege Affiliated to Peking University), who were divided into CWSI group (n=43) and IWSI group (n=31) based on vas-cular teritories.Clinical and demographic features and neuroradiological features were compared between two groups .Re-sults Compared with the IWSI group , CWSI group had a higher incidence of atrial fibrillation and more frequently con-comitant small cortical infarcts (P=0.033 and P=0.028, respectively).In contrast, IWSI group had a higher degree of stenosis or occlusion in the middle cerebral artery (P=0.022) and exhibited a rosary-like pattern of infarction more fre-quently (P=0.003).Patients in IWSI group had higher NIHSS scores before discharge and longer hospital stay than CWSI group (P=0.027 and P=0.031, respectively).No significance was found between two groups in the colleteral ability of Willis circle (P>0.05).Conclusions CWSI are caused mainly by embolic pathogenesis , whereas hemodynamic com-promise appears to contribute greatly to the genesis of IWSI .Patients with IWSI show poor early clinical courses .
