Acute vasoparalysis after subarachnoid haemorrhage and cerebral trauma: general reflex phenomenon?
In patients with head trauma and consecutive acute diffuse cerebral swelling the sudden initial rise in intracranial pressure with subsequent impairment of cerebral blood flow is explained by engorgement due to vasoparalysis. How quickly hyperaemic brain swelling can occur is shown by a case report. The review of clinical and experimental data shows strong evidence that a general reflex phenomenon could be the result of this initial vasoparalysis in acute diffuse cerebral swelling in head trauma and acute aneurysmal subarachnoid haemorrhage.
