[Use of intraoperative ultrasound in neurosurgery].
Intraoperative ultrasound (US) is a device which is a great help to neurosurgeon in intracerebral lesions localization, in the definition of inner tumors structure, in its relation to the surrounding structures, as well as during stereotaxic operations. We report our experiences with US in more than 500 operations. Its maximum usage is during gliomas and metastases operations because of their subcortical localization. Choosing this optimal approach to the tumor, the surrounding brain is minimally damaged. Using modern devices we are able to distinguish edema from infiltrative gliomas, which was not possible using former devices (both edema and gliomas are hyperechoic). In vascular neurosurgery we use US mostly in the localization of small arteriovenous malformations (AVMs). In pediatric neurosurgery the usage is very often in drainage operations for ventricular catheter placement control. The main US shortage is lower image resolution, and the basic advantage is real time imaging. It enables our prompt intervention in every unfavorable situation.
