Anatomical hemispherectomy approaches have largely been abandoned in most cases due to a higher risk of superficial hemosiderosis, intraoperative blood loss, hydrocephalus, prolonged hospital stay, and mortality compared to the variety of tissue-sparing hemispherotomy techniques. Disconnective hemispherotomy approaches utilize the lateral ventricle as a key component of the surgical corridor. Without a lateral ventricle, disconnective surgery becomes significantly challenging, typically leading to a hemispherectomy. The authors present the case of a patient with severe hemispheric dysplasia without a lateral ventricle on the pathologic side and detail a novel surgical technique for a prone, occipital interhemispheric, tissue-sparing, purely disconnective aventricular hemispherotomy with an excellent surgical outcome.<\/jats:p>","DOI":"10.3171\/2020.5.peds20247","type":"journal-article","created":{"date-parts":[[2020,8,28]],"date-time":"2020-08-28T03:10:39Z","timestamp":1598584239000},"page":"642-647","source":"Crossref","is-referenced-by-count":1,"title":["Aventricular hemispherotomy: technical note"],"prefix":"10.3171","volume":"26","author":[{"given":"Cameron","family":"Brimley","sequence":"first","affiliation":[{"name":"Geisinger Neuroscience Institute, Department of Neurosurgery, Danville;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vivek P.","family":"Buch","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Children\u2019s Hospital of Philadelphia;"},{"name":"Department of Neurosurgery, The University of Pennsylvania, Philadelphia, Pennsylvania;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jared M.","family":"Pisapia","sequence":"additional","affiliation":[{"name":"Maria Fareri Children\u2019s Hospital, Westchester Medical Center, Valhalla; and"},{"name":"New York Medical College, Valhalla, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benjamin C.","family":"Kennedy","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Children\u2019s Hospital of Philadelphia;"},{"name":"Department of Neurosurgery, The University of Pennsylvania, Philadelphia, Pennsylvania;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"1","key":"b1","series-title":"Epilepsia","doi-asserted-by":"publisher","first-page":"133","DOI":"10.1111\/j.1528-1167.2006.00909.x","article-title":"Hemispheric surgery in children with refractory epilepsy: seizure outcome, complications, and adaptive function","volume":"48","author":"Basheer SN","year":"2007","unstructured":"Basheer SN, Connolly MB, Lautzenhiser A,  Hemispheric surgery in children with refractory epilepsy: seizure outcome, complications, and adaptive function.
