RESUMO
Objective To investigate the value of B-type ultrasound during and after operations in patients sustaining craniocerebral injury in Wenchuan earthquake. Methods The patients with suspected multiple intracranial hematomas due to intraoperative acute encephalocele were referred for B-type ultrasonic examination. After the operation, B-type ultrasonic examination was performed at the cranial defects or the site of cranial drilling by horizontal coronal or sweep scanning. Results Open cranial surgery was performed in 58 cases of craniocerebral injury resulting from the earthquake. Intraoperative B-type ultrasound was used in 24 cases, and intracranial hematomas or hemorrhage in different brain regions were found in 18 cases. Hematomas in the injured hemisphere were found in 2 cases, and ultrasound-guided hematoma clearance was performed in 14 cases. In 28 cases, postoperative B ultrasonic examination was carried out along with CT scanning, and the results demonstrated basic agreement between the two medalities. Conclusions Intraoperative B-type ultrasound may help accurately localize multiple intracranial hematomas and can be crucial to identify the causes of intraoperative acute encephalocele. Postoperative sweep scanning with B-type ultrasound at the cranial defect can accurately identify delayed hematoma to allow timely management and improve the operative SUCCESS.
