Abstract:
Objeetive To explore the correlative factors of early progressive motor deficits in cerebral infarction of moderately size in basal ganglia and the relationship between motor deficit progression and the stem lesion of middle cerebral artery.Methods One hundred and fifty patients with single acute infarction located in white matter of basal ganglia region were recruited in this study retrospectively.All patients were performed brain and neck MRI and magnetic resonance angiography (MRA) within 72 h after onset.They were divided into two groups based on the maximal diameter of infarction on diffuse weighing imaging(DWI):moderate size infarction group(75 patients,maximal diameter of infarction from 1.5 cm to 3.0 cm) and lacunar infarction group(75 patients,maximal diameter of infarction lower than 1.5 cm).The scores of dynamic National Institutes of Health Stroke Scale(NIHSS) in 7 d after the admission and multiple Logistic regression analysis were used and the risk factors of the early progressive motor deficits were analyzed.Results The rate of early progressive motor deficits in moderate size infarction group was significant higher than that in lacunar infarction group [32.0 ％ (24/75) vs.8.0 ％ (6f75)] (P ＜ 0.05).The multiple Logistic regression analysis showed that elevated systolic blood pressure on admission was the independent risk factor for early progressive motor deficits (P =0.016).The rate of stem lesion of middle cerebral artery in moderate size infarction group was significantly higher than that in lacunar infarction group [41.3 ％ (31/75) vs.9.3 ％ (7/75)] (P ＜ 0.01).Conclusions Patients with acute single infarction located in white matter of basal ganglia and with the diameter of 1.5-3.0 cm are more prone to early progressive motor deficits and elevated systolic blood pressure on admission is the most significantly independent factor.The pathogenic mechanism may be associated with the stem lesion of middle cerebral artery.
