  • Title: Spontaneous Intracranial Hypotension: Controversies in Treatment.
    Author: Signorelli F, Visocchi M.
    Journal: Acta Neurochir Suppl; 2023; 135():209-211. PubMed ID: 38153471.
    Abstract:
    Spontaneous intracranial hypotension (SIH) is a disorder of low cerebrospinal fluid (CSF) volume secondary to CSF leakage through a dural defect along the neuraxis with an estimated incidence of 5 people per 100,000.Great debate persists on the optimal treatment of this pathology, and clinical results are often contradictory. SIH may be initially approached via conservative measures, such as bed rest that is often supplemented with hydration, caffeine, and theophylline, which overall relieve symptoms in a small subset of patients at 6 months. Epidural blood patching (EBP) is generally the next consideration in symptom management. It is the most commonly performed intervention for spinal CSF leaks, as the first option or following the failure of conservative treatment. Further procedures may be performed in the case of EBP partial or temporary response and if the spinal CSF leak has been definitively localized (Beck et al., Neurology 87:1220-26, 2016). In those cases, if the CSF leak is well localized, the surgical closure of the spinal CSF leak may be considered.SIH is a complex but treatable CSF disorder. Despite recent advances in the field of neuroimaging and the different therapeutic options available, the appropriate management remains controversial and should be tailored to the patient.
