Abstract
INTRODUCTION
An increasing amount of evidence suggests that extent of resection is an important prognostic marker for patients who has undergone surgery for brain tumors. Intraoperative ultrasound is an easy, widely accessible, cost-effective real-time method that provides a surgical guidance for the surgeon. The aim of this study is to determine the location of tumor after craniotomy with intraoperative ultrasound, to find the correlation between ultrasound findings and the pathology results and also to investigate the efficacy of intraoperative ultrasound use in the detection of residual tumor peroperatively.
METHODS
59 operations performed for 52 patints diagnosed with brain tumor by a single surgeon (Dr. Camlar) in University of Health Sciences, Izmir Tepecik Education and Research Hospital department of Neurosurgery between 01.01.2014 and 10.07.2018 were retrospectively screened. 27 operations for 25 patients is excluded from the study because intraoperative ultrasound was not used. Thirty two operations performed for 27 patients was studied. The relationship between intraoperative ultrasound images and results of perioperative residual tumor and pathology were investigated. Also the efficacy of intraoperative ultrasound for the detection of the lesion peroperatively was determined.
RESULTS
The intraoperative ultrasound image quality was found to be statistically significantly better in patients who has tumor with cystic component (p <0.001). It was also found that there was no statistically significant effect of pathology to the quality of intraoperative ultrasound image (p = 0,811). The supratentorial or infratentorial location of the tumor did not affected the intraoperative ultrasound image quality (p=1).
DISCUSSION AND CONCLUSION
It is envisaged that the use of intraoperative ultrasound is an easy and cost effective method of neurosurgical tumor resection and its use will become increasingly widespread.
