ABSTRACT
Objective To investigate the imaging characteristics, clinical features and outcomes of penetrating ar-tery disease (PAD) cerebral infarction. Methods One hundred cases of cerebral infarction were divided into 44 cases of PAD group and 56 cases of LAA (large artery atherosclerosis ) group by brain MRI and neck CTA, or DSA neck artery ultrasound. The clinical features, imaging characteristics, outcome and progressive motor deficits(PMD) were compared between PAD cerebral infarction and large artery atherosclerosis (LAA) cerebral infarction. Results There were For-ty-four (44%) cases of PAD cerebral infarction, 56 (56%) cases of LAA cerebral infarction according to 2011 Chinese ischemic stroke subclassification (CISS). The smoking, drinking and TIA histories was significantly less in PAD group (27.27%) than in LAA group (50%) (P=0.021,0.023 and 0.025 respectively,);compared with LAA group, PMD occured in PAD group more frequently. (56.82% vs. 30.36%, P=0.008); lesions were located in the lateral ventricles in most PAD group which was significantly different from LAA group (52.27% vs. 21.43%, P=0.001). Modified Rankin Scale, (mRS) was not significantly different between two groups (1.43 ± 1.17 vs. 1.43 ± 1.45, P=0.99) at 3 months. Conclu-sions Patients with PAD cerebral infarction have PMD at early stage but have good prognosis at three months.
