Decompressive Craniectomy: From Ancient Practices to Modern Neurosurgery.

Area of Science:

• Neurosurgery
• Neurology
• Critical Care Medicine

Background:

• Decompressive craniectomy (DC) is a critical neurosurgical intervention.
• It aims to reduce elevated intracranial pressure (ICP) and manage brain herniation.
• Historical context and modern applications of DC are relevant in neurocritical care.

Purpose of the Study:

• To review the historical evolution of decompressive craniectomy.
• To elucidate the mechanisms of ICP reduction and improved cerebral blood flow via DC.
• To assess the efficacy and complications of DC in various neurological conditions.

Main Methods:

• Literature review of historical and contemporary studies on decompressive craniectomy.
• Analysis of physiological mechanisms underlying DC's effects on ICP and cerebral perfusion.
• Examination of clinical outcomes, complications, and ethical considerations.

Main Results:

• DC has ancient origins and evolved into a key treatment for conditions causing high ICP.
• The procedure effectively reduces intracranial pressure and enhances cerebral blood flow.
• DC demonstrates efficacy in severe traumatic brain injury and stroke, but carries risks like infection and bleeding.

Conclusions:

• Decompressive craniectomy is a vital neurosurgical technique for managing life-threatening intracranial pressure.
• Careful consideration of efficacy, complications, and ethical dilemmas, especially in pediatric cases, is essential.
• Further research may refine DC's role and optimize patient selection and outcomes.
