Introduction: Ischemic Cerebrovascular disease (ischaemic stroke) is a leading public health problem. Stroke is defined as an abrupt neurologic deficit that is attributable to focal vascular cause. Risk factors for stroke include hypertension, carotid stenosis, atrial myxomas, smoking, hyperlipidemia, diabetes, myocardial infarction and atrial fibrillation. Aims and objectives: To study the incidence of ischaemic stroke due to intracranial, extracranial and combined vascular lesions. Material and Method: in the present study 104 cases of ischemic stroke were included in the study. All these patients were studied clinically and radiologically to study the nature of lesion (intracranial or extracranial vascular lesion). Neuroimaging- MRI-Brain or CT-Brain was done in each patient to see site of infarct. Results: It was observed that out of 104 patients included in our study, 28.84% patients were having intracranial vascular lesion, 31.73% patients were having extracranial vascular lesion and 7.69% patients were having combined intracranial and extracranial vascular lesions. 31.73% patients were having normal angiographic study. Incidence of stroke increases with increasing age and has male preponderance. Hypertension was found in 76.92% of total patients. 41.35% of patients in our study were having diabetes mellitus. History of smoking was observed in 33.65% of patients. Conclusion: The incidence of stroke due to intracranial, extracranial and combined vascular lesion was 28.84%, 31.73% and 7.69% respectively. Increasing age, male sex, HTN, DM, IHD, past history of stroke and smoking were important risk factors for ischaemic strokes.
