However, The ICP can also be assessed through a non-invasive method, comprised of the measurement of the optic nerve sheath diameter (ONSD) through ultrasound (US).<\/jats:p><jats:p>\n          Objective\u2003To evaluate the ICP of patients who underwent wide decompressive craniectomy after middle cerebral artery (MCA) infarction via preoperative and postoperative ONSD measurements.<\/jats:p><jats:p>\n          Methods\u2003A total of 17 patients, aged between 34 and 70 years, diagnosed with malignant MCA infarction with radiological edema and mid-line shift, who underwent decompressive surgery, were eligible. From the records, we collected data on age, sex, preoperative and postoperative Glasgow Coma Scale (GCS) scores, National Institutes of Health Stroke Scale (NIHSS) score, the degree of disability in the preoperative period and three months postoperatively through the scores on the Modified Rankin Scale (MRS), and the preoperative and postoperative midline shift measured by computed tomography (CT) scans of the brain.<\/jats:p><jats:p>\n          Results\u2003Preoperatively, the mean GCS score was of 8 (range: 7.7\u20139.2), whereas it was found to be of 12 (range 10\u201314) on the first postoperative day (p\u2009=\u20090.001). The mean preoperative NIHSS score was of 21.36\u2009\u00b1\u20092.70 and, on the first postoperative day, it was of 5.30\u2009\u00b1\u20090.75 (p\u2009&lt;\u20090.001). As for the midline shift, the mean preoperative value was of 1.33\u2009\u00b1\u20090.75\u2009cm, and, on the first postoperative day, 0.36\u2009\u00b1\u20090.40\u2009cm (p\u2009&lt;\u20090.001). And, regarding the ONSD, the mean preoperative measurement was of 5.5\u2009\u00b1\u20090.1\u2009mm, and, on the first postoperative day, it was of 5\u2009\u00b1\u20090.9\u2009mm
