Estimation of prognosis in patients after decompressive craniectomy after malignant hemispheric infarction:...

Area of Science:

• Neurosurgery
• Neurology
• Critical Care Medicine

Background:

• Decompressive hemicraniectomy is used for malignant hemispheric infarction, but patient selection, especially for older individuals or those with severe symptoms, remains challenging.
• Current criteria for surgical indication in malignant brain infarction do not fully address prognostic uncertainties in older patients or those with significant neurological deficits.

Purpose of the Study:

• To develop a multifactorial scoring scale to optimize prognosis assessment in patients undergoing decompressive hemicraniectomy for malignant stroke.
• To improve decision-making regarding surgical indications by providing a data-driven prognostic tool.

Main Methods:

• Prospective observational study with a one-year follow-up of patients treated with decompressive hemicraniectomy for malignant brain infarction.
• Assessment of clinical and imaging data, with the Barthel index used as the primary outcome measure.
• Statistical analysis to identify variables associated with clinical outcomes and development of a predictive scoring system.

Main Results:

• Patient age, preoperative consciousness level, midline shift, and infarct volume were significantly associated with the postoperative Barthel index.
• A multifactorial prognostic scoring system was developed, achieving an Area Under the Curve (AUC) of 0.74 (95% CI 0.58–0.89, p=0.01) in ROC analysis.
• The scale effectively distinguishes between favorable and unfavorable outcomes.

Conclusions:

• Prognostic prediction after decompressive hemicraniectomy should integrate multiple clinical and imaging variables.
• The developed scoring scale aids in decision-making to estimate the potential benefits of decompressive craniectomy in malignant brain infarction patients.
• This tool can enhance the selection of appropriate candidates for hemicraniectomy, particularly in complex cases.
