Decompressive Hemicraniectomy for Malignant Middle Cerebral Artery Infarct

Area of Science:

• Neurosurgery
• Neurology
• Critical Care Medicine

Background:

• Malignant middle cerebral artery (MCA) infarcts often lead to severe brain swelling and neurological deficits.
• Decompressive hemicraniectomy (DHC) is a surgical intervention aimed at reducing intracranial pressure and improving outcomes in select patients.

Purpose of the Study:

• To evaluate the surgical treatment outcomes of decompressive hemicraniectomy in patients with malignant MCA infarct.
• To identify factors associated with favorable and unfavorable outcomes following DHC.

Main Methods:

• Retrospective analysis of 42 patients who underwent DHC for malignant MCA infarct.
• Evaluation of clinical condition, radiological findings, and Glasgow Outcome Scale (GOS) scores.
• Statistical analysis to determine associations between patient characteristics and surgical outcomes.

Main Results:

• A significant association was found between favorable outcomes and younger age, higher preoperative Glasgow Coma Scale (GCS) scores, shorter duration to surgery, and non-dominant hemisphere infarct.
• Patients with a GCS score of 7 or below preoperatively had universally poor outcomes.
• Out of 42 patients, 15 achieved a favorable outcome (GOS 4-5), while 27 had an unfavorable outcome (GOS 1-3).

Conclusions:

• Decompressive hemicraniectomy can be a life-saving procedure for malignant MCA infarct.
• DHC is not recommended for patients presenting with a GCS score of 7 or below due to poor prognosis.
