The authors report the case of a delayed intracranial hematoma following sEEG. This 10-year-old boy was referred to the authors' department to undergo an sEEG study for intractable epilepsy, with the hypothesis of a single localized epileptic zone in the left precentral region. To perform the exploration, 14 depth electrodes were implanted under stereotactic conditions. The results of a postoperative CT scan performed routinely at the end of the surgical procedure were normal. Eight days later, following an epileptic seizure, the child's condition worsened. The neurological examination revealed a left hemiparesis, agitation, and coma due to a right subdural hematoma with intraparenchymal bleeding. Despite a surgical evacuation followed by a decompressive craniectomy, the curative treatments were stopped 1 week later due to severe diffuse ischemic lesions found on MRI studies.<\/jats:p>\n<jats:p>This is the first observation of a delayed hematoma following an sEEG procedure. The mechanism underlying this complication remains unclear, but the rupture of a growing pseudoaneurysm caused by the electrode's implantation or the tearing of a neighboring vessel by an electrode were suspected. In consequence, physicians must remain vigilant during the entire sEEG recording period and probably also several days after electrode removal.<\/jats:p>","DOI":"10.3171\/2012.8.peds12114","type":"journal-article","created":{"date-parts":[[2012,9,28]],"date-time":"2012-09-28T18:57:45Z","timestamp":1348858665000},"page":"525-528","source":"Crossref","is-referenced-by-count":26,"title":["Delayed intracranial hematoma following stereoelectroencephalography for intractable epilepsy"],"prefix":"10.3171","volume":"10","author":[{"given":"St\u00e9phane","family":"Derrey","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Axel","family":"Lebas","sequence":"additional","affiliation":[{"name":"Neurophysiology,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominique","family":"Parain","sequence":"additional","affiliation":[{"name":"Neurophysiology,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie Gilles","family":"Baray","sequence":"additional","affiliation":[{"name":"Anesthesiology, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christophe","family":"Marguet","sequence":"additional","affiliation":[{"name":"Pediatrics, Rouen University Hospital, Rouen, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Freger","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fran\u00e7ois","family":"Proust","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-peds12114","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1097\/00006123-199707000-00004","article-title":"Surgical and neurological complications in a series of 708 epilepsy surgery procedures","volume":"41","author":"Behrens","year":"1997"},{"key":"b2-peds12114","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"74","DOI":"10.1016\/S0090-3019(96)00277-7","article-title":"Invasive monitoring of limbic epilepsy using stereotactic depth and subdural strip electrodes: surgical technique","volume":"48","author":"Blatt","year":"1997"},{"key":"b3-peds12114","series-title":"Can J Neurol Sci","doi-asserted-by":"publisher","first-page":"223","DOI":"10.1017\/S0317167100005023","article-title":"Morbidity associated with the use of intracranial electrodes for epilepsy surgery","volume":"33","author":"Burneo","year":"2006"},{"key":"b4-peds12114","series-title":"Neurological Surgery","first-page":"4271","article-title":"Neurosurgical aspects of epilepsy in children and adolescents","author":"Cahan","year":"1990"},{"key":"b5-peds12114","series-title":"Laryngoscope","doi-asserted-by":"publisher","first-page":"326","DOI":"10.1097\/00005537-199803000-00004","article-title":"Epistaxis originating from traumatic pseudoaneurysm of the internal carotid artery: diagnosis and endovascular therapy","volume":"108","author":"Chen","year":"1998"},{"key":"b6-peds12114","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"706","DOI":"10.1227\/01.NEU.0000176656.33523.1e","article-title":"Stereoelectroencephalography in the presurgical evaluation of focal epilepsy: a retrospective analysis of 215 procedures","volume":"57","author":"Cossu","year":"2005"},{"key":"b7-peds12114","series-title":"J Neurosurg Sci","first-page":"195","article-title":"Iatrogenic intracranial aneurysm.
