Minimally invasive endoscopic transventricular hemispherotomy for medically intractable epilepsy: a new approach and cadaveric demonstration: Laboratory investigation

摘要: Object Surgery for medically intractable epilepsy secondary to unihemispheric pathology has evolved from more aggressive hemispherectomy less variations of hemispherotomy. The authors propose a novel minimally invasive endoscopic hemispherotomy that should give results comparable conventional open craniotomy and microsurgery. Methods Endoscopic transventricular was performed in 5 silicon-injected cadaveric heads the authors' neurosurgery laboratory. lateral ventricle accessed endoscopically through frontal occipital bur hole. White matter disconnections were unroof temporal horn disconnect frontobasal region, corpus callosum, fornix. Results Using an approach, all white successfully cadavers. Conclusions have demonstrated feasibility model. technique is s...
