NLRP3 and Hydrocephalus: We unveiled the diagnostic value of serum NLRP3, metalloproteinase‐9 (MMP‐9) and interferon‐γ (IFN‐γ) levels in post‐craniotomy intracranial infections and hydrocephalus in patients with severe craniocerebral trauma to investigate the high risk factors for these in patients with TBI, and the serological factors predicting prognosis, which had a certain clinical predictive value.
