The authors demonstrate the operative feasibility of a contralateral posterior interhemispheric transfalcine transprecuneus approach (PITTA) to this region and present a series of patients treated via this operative route.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>METHODS<\/jats:title>\n<jats:p>Fourteen consecutive patients underwent the PITTA and were included in this study. Pre- and postoperative clinical and radiological data points were retrospectively collected. Complications and extent of resection were reviewed.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>RESULTS<\/jats:title>\n<jats:p>The mean age of patients at the time of surgery was 39 years (range 11\u201364 years). Six of the 14 patients were female. The mean duration of follow-up was 4.6 months (range 0.5\u201319.6 months). Pathology included 6 arteriovenous malformations, 4 gliomas, 2 meningiomas, 1 metastatic lesion, and 1 gray matter heterotopia. Based on the results shown on postoperative MRI, 1 lesion (7%) was intentionally subtotally resected, but \u2265 95% resection was achieved in all others (93%) and gross-total resection was accomplished in 7 (54%) of 13. One patient (7%) experienced a temporary approach-related complication. At last follow-up, 1 patient (7%) had died due to complications of his underlying malignancy unrelated to his cranial surgery, 2 (14%) demonstrated a Glasgow Outcome Scale (GOS) score of 4, and 11 (79%) manifested a GOS score of 5.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>CONCLUSIONS<\/jats:title>\n<jats:p>Based on this patient series, the contralateral PITTA potentially offers numerous advantages, including a wider, safer operative corridor, minimal need for ipsilateral brain manipulation, and better intraoperative navigation and working angles.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2015.3.jns14847","type":"journal-article","created":{"date-parts":[[2015,5,1]],"date-time":"2015-05-01T13:59:56Z","timestamp":1430488796000},"page":"1045-1054","source":"Crossref","is-referenced-by-count":22,"title":["Posterior interhemispheric transfalcine transprecuneus approach for microsurgical resection of periatrial lesions: indications, technique, and outcomes"],"prefix":"10.3171","volume":"123","author":[{"given":"Bradley N.","family":"Bohnstedt","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles G.","family":"Kulwin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mitesh V.","family":"Shah","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aaron A.","family":"Cohen-Gadol","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-jns14847","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"1046","DOI":"10.1227\/00006123-199412000-00005","article-title":"Surgical management of arteriovenous malformations in the region of the ventricular trigone","volume":"35","author":"Barrow","year":"1994"},{"key":"b2-jns14847","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"511","DOI":"10.3171\/jns.1987.67.4.0511","article-title":"Surgical approaches to trigonal arteriovenous malformations","volume":"67","author":"Batjer","year":"1987"},{"key":"b3-jns14847","series-title":"Acta Neurochir (Wien)","first-page":"83","article-title":"Intraventricular meningioma.
