However, some patients can develop severe and symptomatic intracranial pressure (ICP) elevations in the immediate postoperative period that can be monitored and treated with external ventricular drain (EVD) placement and controlled cerebrospinal fluid (CSF) diversion until the ICP normalizes and symptoms resolve.<\/jats:p>\n <\/jats:sec>\n \n OBSERVATIONS<\/jats:title>\n The authors describe the case of a 39-year-old male who underwent ETV and intraoperative EVD placement for obstructive hydrocephalus associated with aqueductal stenosis. The patient was noted to have sustained ICP elevations in the immediate perioperative period but ultimately experienced a successful clinical outcome without requiring a ventriculoperitoneal shunt.<\/jats:p>\n <\/jats:sec>\n \n LESSONS<\/jats:title>\n Significant sustained ICP elevations in the immediate postoperative period following ETV can occur and may indicate a prolonged adjustment period. These elevations can be tolerated if the patient\u2019s symptoms and ICP are well controlled, with temporary external CSF diversion if the patient becomes symptomatic, as the ICP will likely normalize with a reassuring clinical outcome.<\/jats:p>\n \n https:\/\/thejns.org\/doi\/10.3171\/CASE24478<\/jats:ext-link>\n <\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/case24478","type":"journal-article","created":{"date-parts":[[2024,12,9]],"date-time":"2024-12-09T01:50:44Z","timestamp":1733709044000},"source":"Crossref","is-referenced-by-count":0,"title":["High intracranial pressure following endoscopic third ventriculostomy: illustrative case"],"prefix":"10.3171","volume":"8","author":[{"given":"Zachary","family":"Sokol","sequence":"first","affiliation":[{"name":"Department of Surgery, Thomas Jefferson University Hospital, Philadelphia, Pennsylvania"},{"name":"Department of Neurosurgery, Lewis Katz School of Medicine at Temple University, Philadelphia, Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rohan V.","family":"Gupta","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Lewis Katz School of Medicine at Temple University, Philadelphia, Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Ziechmann","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Lewis Katz School of Medicine at Temple University, Philadelphia, Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scott R.","family":"Shepard","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Lewis Katz School of Medicine at Temple University, Philadelphia, Pennsylvania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"6","key":"bib1","series-title":"J Neurosurg","first-page":"1032","article-title":"Complications of endoscopic third ventriculostomy","volume":"96","author":"Schroeder","year":"2002","unstructured":"Schroeder HWSNiendorf WRGaab MR.
