Correlation between Regional Leptomeningeal Collateral Score by MR Angiography and Clinical Outcome in Patients with Acute Ischemic Stroke

Dr. Shifa Mohammadi, Dr. Vinay Prabhu

Abstract: The therapeutic decision-making in patients presenting with acute ischemic stroke (AIS) is greatly influenced by ascertainment of prognosis, which, in turn, depends on the vulnerability of the brain tissue to ischemia. This decision-making is based on information obtained from clinical and radiologic assessments. Status of collateral blood vessels is one such important radiological parameter. Following the onset of ischemic stroke, survival of the brain tissue distal to an arterial occlusion is dependent on the status of leptomeningeal collateral (LMC) pathways.
