Diagnostic Value Of Intraoperative Real-time Ultrasound In Glioma Grading

Objective Glioma is still incurable,with a high annual incidence and a high risk of recurrence after systematic treatment,placing a great burden on patients and society,it is a difficult problem in neurosurgery to accurately evaluate the biological characteristics of tumors and to safely and completely resect glioma.With the development of technology,the clinical application of intraoperative imaging techniques in neurological disorder glioma surgery has been gradually developed.intraoperative ultrasound is a simple and easy technique to be popularized.Post operative recurrence of glioma may be closely related to the grade of glioma.At present,the grading of gliomas mainly depends on postoperative pathology,and it is a difficult problem whether the biological characteristics of glioma can be accurately evaluated before operation.The purpose of this study was to investigate the relationship between the ultrasonic appearance of glioma and the pathological grade of glioma from the level of intraoperative ultrasound,and to find an effective auxiliary examination technique,according to the clinical requirement.The purpose of this study was to investigate the relationship between the glioma and the pathological grade of glioma,to explore a new method for preoperative evaluation and grading of.glioma.To analyze the application of intraoperative ultrasound in Glioma surgery and its diagnostic value in the grading of gliomas.Methods 50 patients admitted to the hospital from October 2017 to October 2019 were selected as the observation group,and 50 patients with Glioma were selected as the control group,and the Glioma examination was not used during the operation,no other imaging techniques were used to assist surgery(neuronavigation,intraoperative magnetic resonance imaging,immunofluorescence,etc.),and both groups were operated under a microscope,to summarize the application of intraoperative ultrasound in glioma surgery and the characteristics of intraoperative ultrasound images in different types of patients.Result In the observation group,28 males and 22 females aged from 22 to 78 years(mean 46.7 to 4.5 years)were observed.In the control group,27 males and 23 females,aged from 21 to 74 years(mean 45.3 to 5.3 years),were operated on at the same time without using intraoperative ultrasound.On the basis of preoperative CT / MRI examination,the rate of intraoperative ultrasonography was 100%,all lesions were accurately located,and the postoperative recovery was good,there was no hemorrhage and brain swelling in the operation area,and no obvious neurological disorder after operation.In the observation group,the lesions of grade I and II were regular in shape,with clear boundary,homogeneous internal echo and no necrotic liquefaction,and in the patients with anaplastic Gliomas,with irregular shape,clear boundary,heterogeneous internal echo and a little necrotic liquefaction The lesions in Grade III and IV were irregular in shape,ill-defined and edematous,heterogeneous in Internal Echo,and large necrotic and liquefying lesions.Conclusions Intraoperative ultrasound localization shows the gliomas,judges the tumor and the blood vessel situation,provides the useful information for the chief surgeon,guides the operation,carries on the preliminary classification to the gliomas through the different ultrasonic image,has the good diagnostic value,it’s worth spreading.
