| ABSTRACT |
|
This study was carried out to find out changes in regional cerebral blood flow(r-CBF) in relation to(i) clinical status of patients with subarachnoid hemorrhage due to ruptured intracranial aneurysms ; (ii) the degree of subarachnoid hemorrhage as indicated by brain CT scanning ; (iii) the severity of angiographic vasospasm, and (iv) other neuropathological condition. Measurement of r-CBF were performed, using 133Xe inhalation method, on 50 patients with ruptured intracranial aneurysms. Some of the major findings were as follows : 1) The degree of abnormalities of blood flow correlated well with the clinical severity of neurological deficits. 2) A marked reduction in r-CBF was found in patients with intracerebral hematoma, ischemic lesion and hydrocephalus. 3) In angiospasm area, r-CBF was found in patients with intracerebral hematoma, ischemic lesion and hydrocephalus. 3) In angiospasm area, r-CBF decreases below 30ml/100gm/min in almost all of the patients, and severity of vasospasm correlated with the decrease of CBF. 4) The measurement of CBF on patients with subarachnoid hemorrhage was thought to the useful for foreseeing the clinical outcome of the patients. |
