Delayed dural graft breakdown and intracranial hypotension following posterior fossa decompression and duraplasty for Chiari malformation type I: illustrative case.

Background: Chiari malformations type I are commonly encountered in pediatric patients. Posterior fossa decompression with or without duraplasty is recommended for patients with intractable symptoms, as well as those showing evidence of brainstem dysfunction.

Observations: In this report, the authors describe the case of a 19-year-old female who presented to the neurosurgery clinic with delayed synthetic dural graft breakdown as well as associated pseudomeningocele and intracranial hypotension.

Predicting traumatic brain injury outcomes using a posterior dominant rhythm.

Objective: Predicting severe traumatic brain injury (sTBI) outcomes is challenging, and existing models have limited applicability to individual patients. This study aimed to identify metrics that could predict recovery following sTBI. The researchers strived to demonstrate that a posterior dominant rhythm on electroencephalography is strongly associated with positive outcomes and to develop a novel machine learning-based model that accurately forecasts the return of consciousness.
