Abstract: INTRODUCTION: The posterior circulation consists of the paired vertebral arteries, the basilar artery, the paired posterior cerebral arteries, and their branches. Posterior circulation strokes represent approximately 20 % of all ischemic strokes. Methodology Patient selection was made after a thorough clinical examination by a physician according to a pre-designed study questionnaire prepared for medullary infarction. After routine hematological examination, all study subjects underwent MRI imaging of the brain. Chest x-ray, Echocardiogram, 4 Vessel Doppler, Fasting Blood Sugar, Post Prandial Blood Sugar, Fasting Lipid Profile, and Renal Profile were performed in all the subjects included in the study. Results: Among 22 patients with medullary infarct, The major clinical feature exhibited by medullary infarct patients was motor weakness seen in 16 patients. Three patients presented with symptoms of incoordination. Major clinical sign was lower cranial nerve involvement Conclusion: All patients with brain ischemia, whether posterior need an extensive evaluation of risk factors. Rehabilitation is an integral part of all stroke survivors and should begin as soon as the patient is medically stable. Extensive cardiac workup and evaluation for hypercoagulable states are useful in identifying correctable causes.
