Intraoperative ultrasound added with neuronavigation in resection of intracranial gliomas

Abstract

Objective To conclude the application experience of intraoperative ultrasound added with neuronavigation in resection of intracranial gliomas.Methods A retrospective analysis was performed on the clinical data of 60 patients with intracranial gliomas,performed resection in our hospital from January 2010 to June 2013 by intraoperative ultrasound added with neuronavigation; 32 of them had high-grade gliomas and 28 low-grade ones.Ultrasonoscopy of different grade gliomas was studied.Results The accuracy of localization was 100％ in 60 patients with intracranial gliomas.Ultrasonic image of high-grade gliomas enjoyed obvious hyperechogenicity and the boundaries were clear usually; ultrasonic image of low-grade ones were slightly hyperechogenic or isoechogenic and the boundaries were indistinct usually.Inhomogeneous hyperechogenic of the ultrasonoscopy of intracranial gliomas before resection and hypoechogenic of residual cavity after resection were noted,respectively.Total removal was achieved in 50 patients,subtotal resection in 6 and partial resection in 4.Brain swelling happened postoperatively in 1 and was remitted by decompressive craniectomy.Hemiplegia happened in 2,and no death occurred postoperatively.Conclusions Intraoperative ultrasound is important to the correct of brain shift,and has clear and important value to the choice of operation approach and incising cortex.Ultrasonic image of high-grade gliomas and calcified lesions enjoys the best view.Intraoperative ultrasound added with neuronavigation can raise resection rate of intracranial gliomas.
