Intraoperative Transcranial Sonography for Detection of Contralateral Hematoma Volume Change in Patients with Traumatic Brain Injury.

The authors present two clinical cases, in which intraoperative transcranial sonography (TCS) was used to detect a change in contralateral hematoma volume. A 51-year-old female and a 5-year-old male underwent osteoplastic craniotomy for epidural hematoma removal. Scant contralateral hematoma was evident by preoperative computed tomography in both patients. Intraoperative TCS was used to detect changes in contralateral hematomas. After observing a volume change in one case, a second operation was performed immediately. Based in this experience, the authors recommend intraoperative TCS for the detection of contralateral hematoma volume changes.
