Primary non-traumatic intracranial hemorrhage. A municipal emergency hospital viewpoint.

The devastating natural history of 138 consecutive admissions for non-traumatic intracranial hemorrhage to a major emergency care municipal hospital is reviewed. Sixty-four percent of the patients had demonstrable intracranial hematomas while 36% had mainly subarachnoid hemorrhage. Hypertension was a related condition in 43% of the parenchymal hematoma patients, while proved aneurysms accounted for 74% of the subarachnoid hemorrhage patients. There was only a 14% survivorship for patients requiring emergent surgery. All operated hematoma patients survived delayed surgery with improved level of responsiveness. The overall mortality was 74% for intracranial hematoma patients and 58% for aneurysm-caused subarachnoid hemorrhage patients.
