Dr Gary Mathern Discusses Differences In Hemispherectomy Procedures Forty seven patients aged 16 or older underwent hemispherectomy between 1996 and 2016. preoperative clinical, imaging and eeg variables are shown in table 1. of 47 patients, 20 were 25 years or older at the time of surgery; 16 were aged between 18 and 24 years, and 11 were aged between 16 and 18 years. the mean age of initial evaluation at our. Epilepsy develops in 75 80% of patients with sws (49). due to the often hemispheric involvement of the disease, hemispherectomy surgery is utilized for seizure control in select cases, typically when there is already prior loss of hemispheric motor function from prior ischemia (50). open in a separate window. figure 4. Moreover, 54% of all patients who failed hemispherectomy experienced their seizure recurrence within 4 postoperative months. of importance, there were no differences between seizure free and seizure recurrence groups with regards to preoperative seizure frequency, localization of preoperative interictal epileptiform discharges, etiology. Since the hemispherectomy was introduced as an epilepsy treatment by mckenzie in 1938, 1 and the first pediatric hemispherectomy series published by krynauw in 1950, 2 various technical modifications have been developed to improve seizure free outcome and minimize surgical complications. 3 7 the original procedure, the anatomic hemispherectomy, although initially successful in creating seizure.
