The authors report on the utilization of an endoscopic ultrasonic aspirator in the resection of intraventricular tumors.<\/jats:p>\n <\/jats:sec>\n \n METHODS<\/jats:title>\n Twelve pediatric patients (10 male, 2 female), ages 1\u201315 years old, underwent surgery via a purely endoscopic approach using a Gaab rigid endoscope and endoscopic ultrasonic aspirator. Two patients presented with intraventricular metastases from high-grade tumors (medulloblastoma, atypical teratoid rhabdoid tumor), 2 with subependymal giant cell astrocytomas (associated with tuberous sclerosis), 2 with low-grade intraparaventricular tumors, 4 with suprasellar tumors (2 craniopharyngiomas and 2 optic pathway gliomas), and 2 with pineal tumors (1 immature teratoma, 1 pineal anlage tumor). Hydrocephalus was present in 5 cases. In all patients, the endoscopic trajectory and ventricular access were guided by electromagnetic neuronavigation. Nine patients underwent surgery via a precoronal bur hole while supine. In 2 cases, surgery was performed through a frontal bur hole at the level of the hairline. One patient underwent surgery via a posterior parietal approach to the trigone while in a lateral position. The endoscopic technique consisted of visualization of the tumor, ventricular washing to dilate the ventricles and to control bleeding, obtaining a tumor specimen with biopsy forceps, and ultrasonic aspiration of the tumor. Bleeding was controlled with irrigation, monopolar coagulation, and a thulium laser.<\/jats:p>\n <\/jats:sec>\n \n RESULTS<\/jats:title>\n In 7 cases, the resection was total or near total (more than 90% of lesion removed). In 5 cases, the resection was partial. Histological evaluation of the collected material (withdrawn using biopsy forceps and aspirated with an ultrasonic aspirator) was diagnostic in all cases. The duration of surgery ranged from 30 to 120 minutes. One case was complicated by subdural hygroma requiring a subduro-peritoneal shunt implant.<\/jats:p>\n <\/jats:sec>\n \n CONCLUSIONS<\/jats:title>\n In this preliminary series, endoscopic ultrasonic aspiration proved to be a safe and reliable method for achieving extensive decompression or complete removal in the management of intra- and\/or paraventricular lesions in pediatric patients.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/2016.10.peds16352","type":"journal-article","created":{"date-parts":[[2017,1,13]],"date-time":"2017-01-13T09:57:38Z","timestamp":1484301458000},"page":"325-332","source":"Crossref","is-referenced-by-count":48,"title":["Initial experience with endoscopic ultrasonic aspirator in purely neuroendoscopic removal of intraventricular tumors"],"prefix":"10.3171","volume":"19","author":[{"given":"Giuseppe","family":"Cinalli","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alessia","family":"Imperato","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Mirone","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuliana","family":"Di Martino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giancarlo","family":"Nicosia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Ruggiero","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ferdinando","family":"Aliberti","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pietro","family":"Spennato","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-peds16352","series-title":"Minim Invasive Neurosurg","doi-asserted-by":"publisher","first-page":"79","DOI":"10.1055\/s-2008-1053462","article-title":"Endoscopic management of craniopharyngiomas: a review of 3 cases","volume":"38","author":"Abdullah J,","year":"1995","unstructured":"Abdullah J, Caemaert J: Endoscopic management of craniopharyngiomas: a review of 3 cases.
