What Is A Hemispherectomy Beth Mulholland Bruidstaart A hemispherectomy is an operation that partially or completely removes or disconnects half of your child’s brain from the rest of their brain. it’s a rare procedure a surgeon performs in a hospital. children (and occasionally adults) typically have this procedure for epilepsy that doesn’t respond to medications. The purpose of hemispherectomy and hemispherotomy is to functionally isolate or eradicate the epileptogenic zone, which is widely diffused throughout the hemisphere. the first series of anatomical hemi spherectomy for the treatment of gliomas was carried out by dandy in 1928. the first anatomical hemispherectomy for the treatment of epilepsy.
What Is A Hemispherectomy Beth Mulholland Bruidstaart 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. 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. Hemispherectomy was introduced by walter dandy in 1928 for removal of a right hemispheric glioma but was pioneered for use in catastrophic epilepsy by mckenzie a decade later . the procedure was abandoned for years due to its morbidity and mortality but was repopularized in 1950 by krynauw, who used it to treat infantile hemiplegia ( 3 ). An anatomic hemispherectomy involves physically removing the diseased hemisphere of the brain including the frontal, parietal, temporal and occipital lobes. the deeper structures in the brain including the thalamus and basal ganglia are left in place, as they are not generally thought to generate seizures. this operation generally results in.
