Abstract
While accurate diagnosis depend on cerebral angiography, the first steps for early detection of ruptured intracranial aneurysm is a circumstantial clinical history. Although the observations of short dated course after are important, differences of opinion concerning the acute phase after onset of subarachnoid hemorrhage still present.
In this paper, from a view point of changes in clinical signs and symptoms, a term of so called acute phase in these cases of ruptured intracranial aneurysm was studies.
One hundred twenty five patients with ruptured intracranial aneurysm admitted to Keio University Hospital and its affiliated hospitals comprise the substance of this study. Articles of observations were following: headache, states of consciousness, meningeal irritation symptom, mental disorders, hemiparesis and findings of the ocular fundi.
Final conclusions cannot be drawn from results of analysis of clinical course in 125 patients. However, it may be strongly suggested from angle of clinical signs and symptoms that the term of acute phase signifies one week duration after rupture. Further studies into this problem are necessary.
