Intracranial hypertension is a major cause of morbidity and mortality in patients with brain injury. If not appropriately treated, it can precipitate brain ischemia, brain herniation and death. Hyperosmolar therapy remains the main armamentarium for management of raised intracranial pressure, especially in patients with diffuse lesions and where surgical options are not applicable. Substantial amount of studies have tried to explore the superiority of hypertonic saline or mannitol over the other. Due to significant heterogeneity in the pathophysiology of patients, variation in treatment threshold, method of drug administration and drug concentration, substantial evidence is lacking to support one agent over other. Hypertonic saline may be more effective than mannitol for lowering raised intracranial pressure. Well designed novel trials need to try to find the answer. Clinical, pathophysiological and biochemical data should be incorporated at bedside while individualizing selection of hyperosmolar therapy, with the aim to improve outcome and minimize harm.Journal of Society of Anesthesiologists of NepalVol. 4, No. 2, 2017, Page: 54-56

Idiopathic intracranial hypertension (IIH) (also called pseudotumour cerebri and, previously, benign intracranial hypertension) is a syndrome of raised intracranial pressure in the absence of an intracranial mass lesion, enlargement of the cerebral ventricles, or venous sinus thrombosis. IIH affects predominantly obese women of childbearing age (>90%). The condition has considerable morbidity from permanent visual loss (up to 25% of cases) and chronic disabling headaches, which result in poor quality of life. Patients presenting acutely with papilloedema must be evaluated urgently for secondary causes of raised intracranial pressure (e.g. space occupying lesion and venous thrombosis). After this, the priority is to assess accurately the threat to vision. In most patients, the condition becomes chronic and the disease burden is mostly from chronic headaches, which need active management, alongside visual monitoring. This chapter does not cover paediatric IIH.

Bilateral Papilloedema

Majority of idiopathic intracranial hypertension (IIH) cases present with bilateral papilloedema. Unilateral papilloedema is a rare condition in IIH. This is a report of one such unusual case. Papilloedema is clinically defined as swelling of the optic nerve head secondary to raised intracranial pressure.1 Disc oedema is a non-specific term that includes papilloedema but also refers to a disc swollen from other causes. Classically, presence of papilloedema is most commonly due to an intracranial space occupying lesion leading to raised intracranial pressure; however, it may be caused due to other aetiologies such as hydrocephalus, shunt failures, idiopathic intracranial hypertension and drugs.2 Idiopathic intracranial hypertension, also known as pseudotumour cerebri, is a disorder characterised by increased intracranial pressure of unclear pathogenesis in the absence of other structural and obstructive lesions. This is a case of acute established unilateral disc oedema secondary to idiopathic intracranial hypertension.

OBJECTIVEReduced intracranial volume (ICV) and raised intracranial pressure (ICP) are assumed to be principal pathophysiological mechanisms in childhood craniosynostosis. This study examined the association between ICV and ICP and whether ICV can be used to estimate the ICP.METHODSThe authors analyzed ICV and ICP measurements from children with craniosynostosis without concurrent hydrocephalus and from age-matched individuals without craniosynostosis who underwent diagnostic ICP measurement.RESULTSThe study included 19 children with craniosynostosis (mean age 2.2 ± 1.9 years) and 12 reference individuals without craniosynostosis (mean age 2.5 ± 1.6 years). There was no difference in ICV between the patient and reference cohorts. Both mean ICP (17.1 ± 5.6 mm Hg) and mean wave amplitude (5.9 ± 2.6 mm Hg) were higher in the patient cohort. The results disclosed no significant association between ICV and ICP values in the patient or reference cohorts, and no association was seen between change in ICV and ICP values after cranial vault expansion surgery (CVES) in 5 children in whom ICV and ICP were measured before and after CVES.CONCLUSIONSIn this cohort of children with craniosynostosis, there was no significant association between ICV and ICP values prior to CVES and no significant association between change in ICV and ICP values after CVES in a subset of patients. Therefore, ICV could not reliably estimate the ICP values. The authors suggest that intracranial hypertension in childhood craniosynostosis may not be caused by reduced ICV alone but rather by a distorted relationship between ICV and the volume of intracranial content (brain tissue, CSF, and blood).

Idiopathic intracranial hypertension is a syndrome of raised intracranial pressure of unknown cause that most often occurs in obese young women. Bilateral papilledema is usually present and can cause severe, irreversible vision loss if left untreated. In this chapter, we review the symptoms, signs, evaluation, and management of idiopathic intracranial hypertension.

Cerebellar Tonsillar Herniation

Lumbar puncture is performed routinely for diagnostic and therapeutic purposes in idiopathic intracranial hypertension, despite lumbar puncture being classically contraindicated in the setting of raised intracranial pressure. We report the case of a 30-year-old female with known idiopathic intracranial hypertension who had cerebellar tonsillar herniation following therapeutic lumbar puncture. Management followed guidelines regarding treatment of traumatic intracranial hypertension, including rescue decompressive craniectomy. We hypothesize that the changes in brain compliance that are thought to occur in the setting of idiopathic intracranial hypertension are protective against further neuronal injury due to axonal stretch following decompressive craniectomy.
