Abstract

The aim of this study was to evaluate the use of intraoperative navigation in combination with ultrasonography. Between December 2008 and June 2009, 19 patients with brain mass lesions underwent surgery with the aid of a TREON navigation system (Medtronic) along with SonoSite ultrasonography. The ultrasonographic image was directly integrated into the navigation system, and the findings were compared. Intraoperative ultrasonography provided immediate ongoing information about the anatomy and pathological lesions. Image overlay of the sonographic display and corresponding topographic scans using this system was able to provide an estimate of brain shift. Thus, Doppler ultrasonography demonstrated flow signals from the surrounding vessels. Using this type of assistance, gross total removal of the lesion was performed in all cases. Intraoperative ultrasonography supported by a navigation system resulted in satisfactory removal of the lesions.
