Abstract

Insights

Malignant middle cerebral artery infarction is deadly, but decompressive hemicraniectomy surgery can reduce mortality and improve outcomes. This surgical decompression is a promising treatment for selected stroke patients.

Area of Science:

  • Neurology
  • Neurosurgery
  • Stroke Medicine

Background:

  • Malignant middle cerebral artery (MCA) infarction affects 10% of supratentorial ischemic stroke patients.
  • High mortality (up to 80%) due to brain edema, herniation, and intracranial pressure (ICP).
  • Limited evidence for osmotic agents; aggressive use may be harmful.

Purpose of the Study:

  • To evaluate the role of surgical decompression in managing malignant MCA infarction.
  • To assess the efficacy of decompressive hemicraniectomy in reducing ICP and mortality.

Main Methods:

  • Pooled analysis of three independent European trials.
  • Inclusion of patients with malignant MCA stroke syndrome.

Main Results:

  • Decompressive hemicraniectomy significantly reduces mortality in large hemispheric infarctions.
  • Surgical decompression effectively lowers ICP and improves neurological outcomes in selected patients.
  • Evidence supports surgical decompression despite existing controversies regarding indications.

Conclusions:

  • Decompressive hemicraniectomy is a beneficial intervention for malignant MCA infarction.
  • It offers a survival advantage and improved outcomes in carefully selected patients.
  • Further research may clarify optimal indications for this life-saving procedure.

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...

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
