ISCHEMIC STROKE: RELEVANCE OF MAGNETIC RESONANCE ANGIOGRAPHY (MRA) FINDINGS AND CORRELATING THE CHANGES WITH VARIOUS CONVENTIONAL AND NONCONVENTIONAL RISK FACTORS
Author: Ravinder Kumar, Jyoti
Objective: This study aims to correlate the magnetic resonance angiography (MRA) changes in ischemic stroke (IS) patients to identify various conventional and nonconventional risk factors. Material and Methods: Total 100 cases with Ischemic stroke ( IS) were clinically evaluated including body mass index, dietary habits, and family history of stroke. MR imaging, MRA, and testing for blood sugar and lipid profile were carried out. Results: The MRA abnormality positively correlated with low density lipids (LDL), Cholesterol and diabetes, and negatively with alcohol consumption and high density lipids (HDL). Out of total 100 patients, 50% were normal, 35% had significant stenosis and 15% had total occlusion. Males have equal incidence of Intracranial stenoses (ICS) and Extracranial stenoses (ECS) but Females are more likely to have ICS. The patients having age <60yrs more likely to have intracranial stenosis and those having age >60yrs are more likely to have extracranial stenosis. Middle cerebral artery (MCA) was the most common arterial territory involved in all stages of infarct. Posterior cerebral artery (PCA) was the next common arterial territory to be involved. Single stenoses are more common in intracranial atherosclerosis (ICAs) and multiple stenoses are more common in extracranial atherosclerosis (ECAs). Conclusion: MRA is a robust imaging technique for determining the severity of stenosis, vascular occlusion, and collateral flow and in the determination of stroke etiologies.
