Diagnosis and Recent Advance in Treatment of Subarachnoid Hemorrhage

Intracranial aneurysms and angiomas are a common cause of spontaneous subarachnoid hemorrhage. Oculomotor palsy and visual-field defects may be caused by aneurysms, and convulsive seizures by angiomas, with or without hemorrhage. In view of recent advances in diagnostic and surgical techniques, intracranial surgery is recommended as the ideal treatment of ruptured intracranial aneurysms. Angiomas should be excised, if feasible, to prevent progressive brain damage or recurrent hemorrhage.
