Summary

Decompressive craniectomy (DC) is a debated procedure for traumatic brain injury and stroke. Evidence suggests timely DC reduces mortality in select patients, with cranioplasty advancements improving outcomes.

Area of Science:

  • Neurosurgery
  • Neurology
  • Critical Care Medicine

Background:

  • Decompressive craniectomy (DC) is a neurosurgical procedure with ancient origins, historically used for various medical and religious reasons.
  • Despite widespread practice, DC remains controversial, necessitating a review of its evidence base, techniques, and complications.
  • Cranioplasty, often a subsequent procedure, requires careful consideration regarding materials, technology, and optimal timing.

Purpose of the Study:

  • To summarize the historical context, techniques, pathophysiology, and complications of Decompressive Craniectomy (DC).
  • To critically evaluate the recent evidence base for DC in Traumatic Brain Injury (TBI) and malignant middle cerebral artery infarction.
  • To review advances in cranioplasty and discuss optimal timing for this reconstructive procedure.

Main Methods:

  • Literature review and evidence synthesis of Decompressive Craniectomy (DC) and cranioplasty.
  • Analysis of historical data, surgical techniques, and pathophysiological mechanisms related to DC.
  • Evaluation of recent randomized trials and non-randomized studies concerning DC for TBI and cerebral infarction.

Main Results:

  • Non-randomized literature trends suggest timely DC intervention in Traumatic Brain Injury (TBI) reduces mortality with acceptable morbidity.
  • Level 1 evidence now supports early DC in young patients with malignant middle cerebral artery infarction, impacting neurosurgical and rehabilitation practices.
  • Ongoing randomized trials in TBI are anticipated to further clarify the role and outcomes of DC.

Conclusions:

  • Current European and North American guidelines recommend judicious use of DC for select patients with Traumatic Brain Injury (TBI) and malignant middle cerebral artery infarction.
  • Advancements in cranioplasty materials and techniques are improving outcomes and patient selection for reconstruction after DC.
  • The evidence base for Decompressive Craniectomy (DC) is evolving, with Level 1 evidence emerging for specific indications like malignant middle cerebral artery infarction.
