Current regimen for high-grade gliomas is maximal safe surgical resection followed by external beam radiotherapy with concurrent temozolamide. Maximal tumor resection, however, must be balanced with preservation of the patient’s neurological function. A crucial prognostic factor in oncological neurosurgery is the extent of resection. Several studies have addressed the importance of extent of resection in gliomas surgery. Despite development in the fields of pre operative and intraoperative neuroimaging and neuromonitoring have ameliorated the survival rate and the quality of life for patients affected by high grade gliomas, the clinical outcome of patients with such gliomas remains extremel…

Intraoperative Ultrasound: Emerging Technology and Novel Applications in Brain Tumor Surgery

2022

Intraoperative ultrasound (IOUS) is becoming progressively more common during brain tumor surgery. We present data from our case series of brain tumor surgery performed with the aid of IOUS in order to identify IOUS advantages and crucial aspects that may improve the management of neurosurgical procedures for brain tumors. From January 2021 to September 2021, 17 patients with different brain tumors underwent brain tumor surgery aided by the use of IOUS. During surgery, the procedure was supported by the use of multiples ultrasonographic modalities in addition to standard B-mode: Doppler, color Doppler, elastosonography, and contrast-enhanced intraoperative ultrasound (CEUS). In selected cas…

Coplanar Indirect-Navigated Intraoperative Ultrasound: Matching Un-navigated Probes With Neuronavigation During Neurosurgical Procedures. How We Do I…

2021

BACKGROUND Intraoperative ultrasound (IOUS) is becoming more and more adopted in neurosurgery, since it has been associated to greater extent of resection (EOR) and to gross total resection (GTR) during brain tumor surgery. IOUS main limitations are spatial resolution, width and orientation of the field of view and scan quality, which are operator-dependent. Furthermore, most neurosurgeons are not confident with this technique, which needs a long learning curve in order to identify and interpret anatomic structures. OBJECTIVE To describe an effective procedure to take advantages of both IOUS and neuronavigation in case of lack of a navigated ultrasound system. METHODS We propose a reliable …

Hemostasis in brain tumor surgery using the Aquamantys system

2014

Background: Adequate hemostasis in cranial and spinal tumor surgery is of paramount importance in neurosurgical practice. Generalized ooze bleeding from the surgical walls cavity, coming from neoplastic vessels or nervous tissue, may be problematic. Recent technical advances have dramatically reduced intraoperative complications related to blood loss. Several techniques are usually employed to control hemostasis in tumor surgery, including preoperative embolization, intraoperative hypotension, electrical coagulation, and local application of fibrin sealants or hemostatic matrix, which influence coagulation. Material/Methods: Our aim in this study was to evaluate the efficacy and the safety …
