Evaluation of Role of Intraoperative Ultrasound in Gross Total Resection of Gliomas

The use of intraoperative ultrasound (IOUS )seems to have significantly increased the Gross total Resection rate achieved in brain gliomas surgery. As regard intraoperative visualisation of the tumor and its residuals, the effectiveness of IOUS has been documented in a series of 192 High Grade glioma patients, in which the combination of neuronavigation and IOUS was also related to increased overall survival in a prospective study of 32 patients, documented a good level of agreement between intraoperative ultrasonography and postoperative contrast-enhanced MRI in detecting tumor residuel they concluded that the IOUS produces results similar to those of MRI, and therefore, can be used to maximize tumor resection.

Inclusion Criteria:Patients with all grades of gliomas confirmed by MRI , MRI with contrast and MR spectroscopy .Age of the patient: any age.Both sexExclusion Criteria:• Other tumours and space occupying lesion (sol) rather than gliomas confirmed by histopathology and preoperative imagingPatients unfit for surgery
