Character of cerebral angiography of subarachnoid hemorrhage:An analysis of 66 cases

Objective:To study the character of cerebral angiography for spontaneous subarachnoid hemorrhage(SAH).Methods: 66 patients with SAH were reviewed retrospectively in terms of clinical symptoms,cerebral CT and cerebral angiography.Results: The major etiology of SAH was identified as intracranial aneurysm,with medium-sized or small-sized intracranial aneurysm as majority. Rotary digital subtraction angiography showed the special relationship of the intracranial aneurysm to anatomic position.The amount of subarachnoid blood from computed tomography(CT) scan were not necessarily matched with the size of aneurysm.The seriousness of cerebral vasospasm in young adults was greater compared with the older.Conclusion: The intracranial aneurysm is the most common cause for SAH,cerebral angiography can make accurate diagnosis of the intracranial aneurysm to anatomic position,appearance and size,and it is chief instrument to ascertain the cause of subarachnoid hemorrhage.
