Although the benefits of this procedure have been widely reported, there is a paucity of data on the pitfalls of posterior fossa shunting in the neurosurgical literature. During the 4-year period from July 1989 to June 1993, we placed fourth-ventricular shunts in 12 patients. Remarkably, 5 patients suffered complications related to posterior fossa catheter placement (42% rate). Three of these patients developed new cranial nerve dysfunction caused by direct injury to the floor of the fourth ventricle, 1 patient suffered an intracystic hemorrhage and acute shunt malfunction, and 1 patient had the catheter tip in the brainstem on postoperative studies without new neurological deficit. We conclude that placement of fourth-ventricular shunts can be fraught with complications which we believe is related to technique. We propose that altering the trajectory of the ventricular catheter from our usual midline technique to a more lateral position will lessen the chances for injury to the floor of the fourth ventricle. In this manner we hope to decrease our incidence of complications for this procedure.<\/jats:p>","DOI":"10.1159\/000120921","type":"journal-article","created":{"date-parts":[[2008,3,7]],"date-time":"2008-03-07T05:47:34Z","timestamp":1204868854000},"page":"309-314","source":"Crossref","is-referenced-by-count":67,"title":["Complications of Fourth-Ventricular Shunts"],"prefix":"10.1159","author":[{"given":"Mark","family":"Lee","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diana","family":"Leahu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Howard L.","family":"Weiner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rick","family":"Abbott","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey H.","family":"Wisoff","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fred J.","family":"Epstein","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2008,3,6]]},"container-title":["Pediatric Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/120921","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000120921","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T17:15:55Z","timestamp":1777742155000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000120921"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2008,3,6]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000120921","archive":["Portico"],"relation":{},"ISSN":["1016-2291","1423-0305"],"issn-type":[{"value":"1016-2291","type":"print"},{"value":"1423-0305","type":"electronic"}],"subject":[],"published":{"date-parts":[[2008,3,6]]}}}
