A subset of patients with IIH will demonstrate a disease course that will require more than medications, weight loss, and other conservative measures. This group of patients comprises two categories: those patients who fail medical management and those with a much more aggressive disease presentation – Fulminant IIH.
The management of these patients differs from those without an aggressive presentation or in those for whom medical therapy is effective. With regards to fulminant IIH specifically, due to the rapidity of symptom onset and the severity of symptoms, the standard treatment measures (including A medication used to manage and treat glaucoma, idiopathic intracranial hypertension, altitude sickness, congestive heart failure, and epilepsy, among other diseases. Click the term to read more and weight reduction) may not be able to adequately prevent further visual deterioration or improve current visual symptoms. These patients can often require urgent aggressive management in order to preserve visual function. This management can refer to temporizing measures or interventions (A surgical procedure performed that allows cerebrospinal fluid to pass around the optic nerve freely Click the term to read more, permanent Fluid that is made by specialized cells in the ventricles of the brain. Click the term to read more diversion (A surgery during which a hollow tube (shunt) is placed in the sinus to help drain cerebrospinal fluid. Click the term to read more), and A minimally invasive surgery during which a metallic mesh in the shape of a tube (stent) is placed in the sinus. Click the term to read more).
As the name suggests, these are not curative steps. They are rather temporary steps that can be undertaken more acutely than other surgical or minimally involving the introduction of instruments or other objects into the body Click the term to read more procedures to prevent further visual deterioration.
Medications such as Medication used to treat glaucoma, epilepsy, altitude sickness, periodic paralysis, idiopathic intracranial hypertension, urine alkalinization, and heart failure. Click the term to read more can be rapidly titrated to a maximum tolerated dose of up to 4g per day. There has also been data that has shown intravenous (IV) steroids such as methylprednisolone to possibly be effective in these urgent situations.
More commonly, patients presenting with severe visual symptoms or a rapid course of visual loss may require a temporizing procedure to preserve vision. This invariably takes the form of temporary removal of Fluid that is made by specialized cells in the ventricles of the brain. Click the term to read more. This can be accomplished in multiple ways.
Most commonly, one or more large volume (greater than 60 mL) lumbar punctures can be performed to temporarily lower intracranial pressure. The caveat with this procedure, in addition to the risks and discomfort associated, is that the effects are limited. The average adult produces 20 mL of CSF per hour, and thus the effects of A procedure where a needle is placed in the lower part of the spine (the lumbar spine) to access cerebrospinal fluid. Click the term to read more may last only a few hours before CSF volume returns to pre-lumbar puncture levels. This procedure can be performed in an office setting and may be a viable option to temporize a patient with a severe presentation while an emergency interventional consultation is arranged.
A more durable temporary CSF diversion procedure is the lumbar drain. This procedure is quite similar to a lumbar puncture in terms of setup and technique and only differs from a lumbar puncture in that a small catheter is inserted into the lumbar subarachnoid space through a larger Tuohy needle. The catheter exits at the puncture site and is attached to a drainage bag. The patient discomfort and risk profile are similar to that of a lumbar puncture, however, the presence of the catheter allows continuous drainage of CSF. This avoids the need for repeated lumbar punctures and can allow more time for permanent interventions to be arranged.
