Abstract

Objectives: To describe the characteristics of subarachnoid hemorrhage (SAH) on MSCT and ruptured aneurysms on cerebral CT angiography  at Quang Ninh Provincial General Hospital. Methods: A cross-sectional descriptive study. Results: Regarding the degree of SAH according to Fisher scale, grade IV accounted for 54.7%, grade III accounted for 42.9%. Regarding some combined lesions, Single SAH accouted for 45.2%. SAH with intraventricular bleeding 35.7%. SAH with cerebral parenchymal bleeding 4.8%. SHA with cerebral parenchymal bleeding and intraventricular bleeding 14.3%. Most aneurysms in the anterior circulation account for 90.4%. Aneurysm in the anterior communicating artery 42.9%. Aneurysm in the internal carotid artery 26.1%.SAH caused by Cerebral aneurysm usually ruptures one aneurysm, medium-sized aneurysm accounted for 54.7% and small-sized aneurysm accounted for 45.2%, ruptured aneurysm was wide neck (54.7%), pouch-shaped aneurysm (97.6%). CT scan of the brain and CT cerebral agiography in the diagnosis of SHA due to ruptured aneurysm artery gives the accuracy up to 100%.
