Abstract

The 121 nontraumatic subarachnoid hemorrhage patients who showed mainly subarachnoid hemorrhage without considerable intracerebral hematoma on C.T. finding admitted at Kyungpook National University Hospital for recent 1 year, were evaluated the exact causes of hemorrhage with variable diagnostic methods including 4-vessels cerebral angiography. Even with full studies of repeated 4-vessels cerebral angiography, 8 patients remained idiopathic cases without the clear causes. Out of 8 patients, authors selected 3 cases who had firm history of spontaneous subarachnoid hemorrhage, revealing some evidence of aneurysmal bleeding characteristics on brain C.T. scannings and cerebral angiographic findings, and operated on them for the perfect treatment with confirming the cause of bleeding. The operation called for treatment by clipping and coating on the aneurysmal sacs found in all the 3 patients.
