Acute cerebral infarction, especially middle cerebral artery (MCA) infarction, can lead to cerebral edema, increasing intracranial pressure and herniation of brain which can be fatal. The purpose of this study was to evaluate the prognostic factors in patients with malignant MCA infarction who underwent decompressive craniectomy during ongoing brain herniation.
From January 2008 to June 2014, we retrospectively reviewed 56 patients with malignant MCA infarction who received decompressive craniectomy for ongoing brain herniation. We divided the patients into two groups according to the functional outcome (Group I: 23 patients showing good result, Barthel index ≥60, Group II: 33 patients showing poor result, Barthel index <60 including death). Patients were evaluated based on the age, location of infarction, National Institute of Health Stroke Scale (NIHSS) at admission, preoperative Glasgow coma scale (GCS).
All patients underwent decompressive craniectomy with wide duroplasty. Good result group (Group I) was significantly younger than poor result group (Group II). Right side involvement and higher GCS level before surgery were also main factors affecting the acceptance of decompressive craniectomy in patients with a malignant MCA infarction. But NIHSS score at admission was not significant factor for functional outcome.
Younger age, higher preoperative GCS score and right side involvement are main favorable factors which should be considered in predicting patients prognosis of decompressive craniectomy for malignant MCA infarction.
