Intraoperative Use of Real Time Ultrasonography Applied to Aneurysm Surgery

Abstract

Abstract The intraoperative application of real time ultrasonography during 13 neurosurgical operations for intracranial aneurysms is reported. In 2 cases, the aneurysms themselves could be detected clearly by real time ultrasonic imaging. In the case of a large aneurysm, information about the nature of the aneurysmal wall was obtained. Other lesions coexisting with the aneurysm (namely, intracerebral hematoma, massive subarachnoid hemorrhage, and hydrocephalus) could be recognized clearly. Real time intraoperative ultrasonography is considered to be useful in aneurysm surgery.
