Thirteen patients (1.8%) experienced seizures within 2 weeks postoperatively. Five of these patients (0.7% of the series) had seizures within 24 hours after operation. The incidence was highest for patients with medulloblastoma (7.2%) followed by those with astrocytoma (2.3%). Also, a higher percentage was found in patients with preoperative ventriculoperitoneal shunt or intraoperative ventriculostomy (2.7%) than in those without (1%), but the difference was not statistically significant. Metabolic acidosis (80%) and hyponatremia (20%) were the major causes of the seizures that developed within 24 hours after operation. Follow-up computerized tomography showed no definite lesion in these patients. Hydrocephalus (75%) and supratentorial hemorrhage remote from the operative site (25%) were detected in the patients who developed seizures between the 2nd and 14th postoperative day. Two of these patients also had postoperative bacterial meningitis. This review suggests that seizures are a possible complication in the early postoperative period after suboccipital craniectomy for posterior fossa lesions.<\/jats:p>","DOI":"10.3171\/jns.1990.73.4.0541","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T18:20:00Z","timestamp":1242238800000},"page":"541-544","source":"Crossref","is-referenced-by-count":21,"title":["Early postoperative seizures after posterior fossa surgery"],"prefix":"10.3171","volume":"73","author":[{"given":"Shih-Tseng","family":"Lee","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tai-Ngar","family":"Lui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen-Nen","family":"Chang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wen-Chun","family":"Cheng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"290","DOI":"10.1227\/00006123-198503000-00002","article-title":"Postoperative prophylactic anticonvulsant therapy in cerebral gliomas.","volume":"16","author":"Boarini","year":"1985"},{"key":"b2","series-title":"J Neurol Neurosurg Psychiatry","doi-asserted-by":"publisher","first-page":"663","DOI":"10.1136\/jnnp.39.7.663","article-title":"Incidence of postoperative epilepsy after a transtentorial approach to acoustic nerve tumours.","volume":"39","author":"Cabral","year":"1976"},{"key":"b3","series-title":"Acta Neurochir","doi-asserted-by":"publisher","first-page":"217","DOI":"10.1007\/BF01401316","article-title":"Postoperative epilepsy in subdural suppurations.","volume":"71","author":"Calliauw","year":"1984"},{"key":"b4","series-title":"Curr Res Anesth Analg","first-page":"72","article-title":"Convulsion during anesthesia.","volume":"7","author":"Clement","year":"1928"},{"key":"b5","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"279","DOI":"10.1016\/0090-3019(82)90122-7","article-title":"The incidence of epilepsy after ventricular shunting operations.","volume":"17","author":"Copeland","year":"1982"},{"key":"b6","series-title":"The Brain.","first-page":"161","author":"Dandy","year":"1969"},{"key":"b7","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"510","DOI":"10.1227\/00006123-198509000-00021","article-title":"Anticonvulsant prophylaxis in neurological surgery.","volume":"17","author":"Deutschman","year":"1985"},{"key":"b8","series-title":"Lancet","first-page":"1299","article-title":"Epilepsy after craniotomy for intracranial aneurysm.","volume":"1","author":"Fabinyi","year":"1980"},{"key":"b9","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"671","DOI":"10.1016\/0090-3019(85)90130-2","article-title":"Immediate postoperative seizures: incidence and computed tomographic findings.","volume":"24","author":"Fukamachi","year":"1985"},{"key":"b10","series-title":"J Neurosurg","first-page":"675","article-title":"Complications from microsurgical treatment of tic douloureux.","volume":"40","author":"Jannetta","year":"1974"},{"key":"b11","series-title":"Neurosurgery.","first-page":"1901","article-title":"Posterior fossa neurovascular compression syndromes other than neuralgias","volume":"2","author":"Jannetta","year":"1985"},{"key":"b12","series-title":"Neurosurgery.","first-page":"2357","article-title":"Trigeminal neuralgia: treatment by microvascular decompression","volume":"3","author":"Jannetta","year":"1985"},{"key":"b13","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"14","DOI":"10.1227\/00006123-198301000-00003","article-title":"Seizures during the immediate postoperative period.","volume":"12","author":"Kvam","year":"1983"},{"key":"b14","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"361","DOI":"10.1016\/0090-3019(89)90067-0","article-title":"Prophylactic anticonvulsants for prevention of immediate and early postcraniotomy seizures.","volume":"31","author":"Lee","year":"1989"},{"key":"b15","series-title":"Br J Anaesth","first-page":"1097","article-title":"Convulsions in the postoperative period: a case report.","volume":"41","author":"Maltby","year":"1983"},{"key":"b16","series-title":"Can J Neurol Sci","doi-asserted-by":"publisher","first-page":"285","DOI":"10.1017\/S0317167100022757","article-title":"Seizures following intracranial surgery: incidence in the first postoperative week.","volume":"7","author":"Matthew","year":"1980"},{"key":"b17","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"672","DOI":"10.3171\/jns.1983.58.5.0672","article-title":"Phenytoin and postoperative epilepsy.
