Rezumat:

Intracranial hypertension is one of the most important syndromes in neurologyand neurosurgery; raised intracranial pressure is the most commoncause of death in neurosurgery. A recent classification of intracranialhypertensionis based upon the etiopathogenesis of intracranialhypertension: a) parenchymatous intracranial hypertension, b) vascularintracranial hypertension, c) meningeal intracranial hypertension and d) idiopathicintracranial hypertension. Vascular etiologies can individualize vascular types ofintracranial hypertension: (1) cerebral venous thrombosis reduces venousoutflow and determines low cerebrospinal fluid drainage and brain edema;(2) hypertensive encephalopathies cause brain swelling, both brain edema andcongestive brain swelling with raised Intracranial Pressure (ICP); (3) ischaemicstroke induces an increased capillary permeability with open brain-blood barrier,brain edema and severe ICP increase. The main features of ICP increase are: thespeed of ICP increase up to and respectively above, the normal limit of ICP, thepathological value of ICP and the duration that the pathological values of ICP aremaintained. These features of ICP increase depend on its etiology: a low speedof ICP increase in cerebral venous thrombosis or a high speed in hypertensiveencephalopathies or in ischaemic strokes. Also the periods when ICP stays athigh values are different depending on the etiologies of ICH: a long period incerebral venous thrombosis and a short period in ischaemic strokes.
