To evaluate the clinical outcomes of patients with malignant middle cerebral artery (MCA) infarction who underwent wide decompressive hemicraniectomy. Fifty- two patients with large MCA infarcts were retrospectively evaluated, and 12 patients who underwent extensive decompressive hemicraniectomy and duraplasty with a bone flap extending beyond the infarct borders were included in the study. The degree of stroke (stroke volume), preoperative and postoperative midline shift of the craniectomy area and improvement in midline shift were calculated on computed tomography. Preoperative and postoperative neurologic examination scores were determined using the modified Rankin Scale. The mean age was 63 (min: 41, max: 79) years. There was left MCA infarction in one patient and right MCA infarction in 11 patients. The postoperative follow-up period of the operated patients ranged from 14 to 90 days. The neurological examination of seven patients (58.3%) showed significant improvement. Eight (66.6%) patients survived. Postoperatively, the mean midline deviation value of 12 patients decreased from 11.04 to 4.8. It is considered that wide decompressive craniectomy performed in young patients in the early period with strict radiological and clinical follow-up can increase survival and functional recovery.
