Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...

Area of Science:

  • Neurosurgery
  • Critical Care Medicine
  • Neurological Surgery

Background:

  • Decompressive craniectomy is a neurosurgical procedure with ongoing debate regarding its efficacy and risks.
  • While recognized as a potentially life-saving intervention, its benefit over standard medical therapy remains unclear.

Purpose of the Study:

  • To critically evaluate the current role of decompressive craniectomy in managing neurological emergencies.
  • To address key questions regarding its life-saving potential, impact on patient outcomes, associated risks, and patient-reported experiences.

Main Methods:

  • This study is a narrative review of existing literature on decompressive craniectomy.
  • The review focuses on analyzing evidence related to the procedure's effectiveness, complications, and patient perspectives.

Main Results:

  • Decompressive craniectomy is unequivocally a life-saving procedure in critical neurological conditions.
  • However, robust evidence demonstrating improved patient outcomes compared to standard medical therapy is less conclusive.
  • The procedure carries significant complications, and patient satisfaction with outcomes varies.

Conclusions:

  • Decompressive craniectomy remains a vital intervention for life-saving in neurological emergencies.
  • Further research is needed to clarify its role in improving long-term patient outcomes and to optimize patient selection and management.
  • Understanding patient perspectives is crucial for holistic care and future procedural refinement.
