BACKGROUND Reversible cerebral vasoconstriction syndrome (RCVS) is a rare cause of intracerebral hemorrhage (ICH) causing intracranial hypertension. METHODS Case report. RESULTS We report a case of RCVS-related ICH leading to refractory intracranial hypertension. A decompressive craniectomy was performed to control intracranial pressure. We discuss here the management of RCVS with intracran...

BACKGROUND During an endoscopic neurosurgical procedure a sudden increase in intracranial pressure may occur at any time. We present a prospective study of haemodynamic changes during such procedures. METHODS Physiological data were recorded during the whole operative procedure in 17 consecutive patients who underwent an endoscopic neurosurgical procedure under general anaesthesia. Monitoring...

UNLABELLED Positive intrathoracic pressure may cause hemodynamic changes, which can be transmitted to the cranial compartment, changing intracranial pressure and cerebral perfusion pressure. This can be increased when high positive end-expiratory pressure values are used. OBJECTIVE To measure the impact of different positive end-expiratory pressure levels on intracranial pressure, cerebral pe...

OBJECT Intracranial pressure (ICP) monitoring is used extensively in clinical practice, and as such, the accuracy of registered ICP values is paramount. Clinical observations of nonphysiological changes in ICP have called into question the accuracy of registered ICP values. Subsequently, the authors have tried to determine if the ICP monitors from major manufacturers were affected by electrosta...

Diffuse leptomeningeal glioneuronal tumor is characterized by hydrocephalus, leptomeningeal involvement in the absence of a primary parenchymal mass, and negative cerebrospinal fluid (CSF) cytology. It is an extremely rare and difficult tumor to diagnose as no mass can be biopsied and it mimics infectious, rheumatologic, and inflammatory pathologies. An 11-year-old girl presented with complaint...

In 10 anaesthetized and ventilated baboons a steady level of raised intracranial pressure was achieved by graduated inflation of an extradural balloon. Measurements were made of the ventricular fluid pressure, and of the change in this pressure after injection of 0·05 ml into the ventricle, the volume-pressure response. This response was studied at normocapnia and at hypocapnia (induced by hype...

The effort that occurs during the Valsalva maneuver provokes a raise in intracranial pressure and may decompensate patients with increased intracranial pressure. The aims of this study were to evaluate the incidence of intestinal constipation in the preoperative period of patients with intracranial tumors and establish a relationship between constipation and intracranial pressure decompensation...

Chronic headaches, associated with papilledema and pulsatile tinnitus without any neuroradiologic, cytobiochemical or cerebrospinal fluid abnormalities are suggestive of idiopathic intracranial hypertension (IIH). However the absence of the papilledema does not rule out this diagnosis. The reason why some patients do not develop papilledema in IIH is ignored, however there are some hypotheses c...
