CLINICAL AND IMAGING CHARACTERISTICS OF DEEP CEREBRAL INFARCTION OF MIDDLE CEREBRAL ARTERY
Main Article Content
Abstract
Objectives: Determine suggesting the possible mechanism and etiology of subgroups of deep cerebral infarction. Subjects and methodology: this is a retrospective comparative study, based on patients with deep cerebral infarction of the middle cerebral after admitted to University Medical Center during the study period. Results: Our study enrolled 157 patients with deep cerebral infarction in the middle cerebral artery, which showed some results as follows: the male/female ratio is 1.7; mean age is around 60. Hypertension and dyslipidemia are common vascular risk factors (93.6% and 74.5%, respectively). Atrial fibrillation is only seen in the striatocapsular infarction affected both distal and proximal region, with a rate of 46.7%. Indicators of small vessel disease (white matter hyperintensities with Fazekas ≥ 2, microbleeds, silent brain infarction) are more common in the distal single small subcortical infarction (64.2%, 23.9%, and 26.9%, respectively). Indicators of atherosclerosis (parent artery disease and atherosclerosis of other cerebral arteries) are common in the proximal single small subcortical infarction (both at 42.3%) and striatocapsular infartion. Conclusion: Distal single small subcortical infarction suggests etiology of small vessel disease, striatocapsular infarction affected both distal and proximal region suggest cardioembloism, and proximal single small subcortical infarction and striatocapsular infarction suggest parent artery athreoscelrosis.
