[Application of intraoperative contrast-enhanced ultrasound in different pathological grades of glioma].

Objective: To explore the feasibility and value of intra-operative contrast-enhanced ultrasound in different pathological grades of glioma.

Methods: A total of 46 patients with glioma were selected to undergo the contrast-enhanced ultrasound. They were divided into 3 groups according to their pathological grades.

Results: All 46 tumors were hyperechoic after examinations and the borders became much more distinct. Different level of tumors had their representative ultrasonic findings.

Conclusions: Intraoperative contrast-enhanced ultrasound is quite useful for determining the position and border of tumors. And it is also excellent in detecting the residual tumor tissues post-operatively. And it can improve the resection accuracy and operative precision, especially for Grade IV glioma with internal necrosis, cyst and surrounding brain edema.
