Detailed Description
The use of intraoperative ultrasound (IOUS) during neurosurgical procedures was first described in 1978 by MH Reid The initial interest towards US as an imaging tool in neurosurgery progressively weaned from the 80's until the early 2000's in favor of other imaging techniques such as CT and MRI
Maximal safe resection represents the gold standard for surgery of malignant brain tumors:
gross total resection of the tumor while preserving the surrounding functional brain tissue is the main goal, since it is associated with longer survival and better patient quality of life This is particularly true for gliomas, the most common primary malignant brain tumors Concerning gross total resection, accurate localization and precise delineation of the tumor margins are required in order to avoid devastating lesions on nervous structures Ultrasound may provide an alternative tool to intraoperative magnetic resonance imaging (MRI) for delineating tumor Tissues and improving the chances of gross total resection The purpose of brain tumor removal is maximal resection while sparing healthy tissues. The extent of resection is a key prognostic factor in survival time, functional recovery, and tumor recurrence rates The optimal results of brain lesion surgery may be achieved by maximal surgical resection without disturbance of neurological functions Due to the imprecise correlation between preoperative images,intraoperative anatomy, and also poor differentiation of some tumors from a normal tissue, better delineation of normal from tumor tissue intraoperatively could improve clinical outcome as increasing chance of total resection and decreasing normal tissue damage . Intraoperative imaging technology increases the extent of tumor resection and patients' outcome including survival time.
Intraoperative MRI are time-consuming and of high cost. Computed tomography (CT) usually is not of choice as ionizing radiation and limited mass delineation. Several researches have demonstrated that the image quality of ultrasound has improved enough to visualize and guide tumor resection The most important disadvantage of neuronavigation is the inconsistency with preoperative images from changes of the lesion and critical anatomic structures associated with brain shift as intraoperative tumor resection or cerebrospinal fluid drainage. This creates the need for updating the preoperative image with the intraoperative image
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.
