Pathophysiology and therapeutic options of intracranial hypertension

Intracranial hypertension has a number of causes with converging mechanisms of secondary brain damage. Vascular autoregulation, blood-brain barrier disruption, membrane depolarization, biochemical cascade with glutamate and free radicals´ effects, and mechanisms of interstitial and intracellular edema are analysed. Common and specific therapeutic measures based on these pathophysiological processes are derived: complex monitoring including intracranial pressure, cerebral perfusion pressure control, sedation, analgesia, therapeutic hyperventilation, barbiturate coma, external ventricular drainage, decompressive craniectomy with focus on new indications in malignant ischemic stroke in the middle cerebral artery territory.
