Introduction: This study evaluates the effectiveness of diagnostic and treatment methods for cerebral artery disorders in tertiary care hospitals in West Bengal. Methodology: A retrospective analysis was conducted on 287 patients diagnosed with cerebral conditions such as ischemic strokes, aneurysms, and arteriovenous malformations from February 2023 to February 2024. Advanced imaging techniques and various treatment modalities were analyzed. Results: The treatment success rates were 75% for ischemic strokes, 68% for aneurysms, and 82% for arteriovenous malformations, with a 15% overall complication rate. MRI was the most commonly used diagnostic tool. Conclusion: High success rates and low complication rates demonstrate the effectiveness of current practices in West Bengal’s tertiary care hospitals. Recommendations: Further enhancement of diagnostic and treatment protocols is advised to improve patient outcomes.
