Application value of real-time B type ultrasound guidance in resection of low-grade gliomas

Abstract

Objective To investigate the application value of real-time B type ultrasound guidance in resection of low-grade gliomas. Methods Seventy-two cases of patients with low-grade gliomas were selected, who were treated at Department of Neurosurgery, Central Hospital of Jiamusi from June 2012 to June 2016, and were divided into observation group (36 cases) and control group (36 cases). Conventional tumor localization method was used in control group prior to resection, while the patients in observation group underwent tumor resection under real-time B type ultrasound guidance. The following aspects were compared between 2 groups including surgical operation, accuracy of tumor localization, total resection rate, ADL (activities of daily living) score and KPS (Karnofsky performance status) score. Results The operation time in the observation group were significantly less than that in control group (P 0.05). The 6-month follow-up showed that the patients’ preoperative KPS scores in observation (81.1±7.8) and control (71.4±9.9) groups were significantly higher than postoperative scores (58.1±8.2, 56.9±9.2, respectively) (P<0.001) and the improvement in observation group was even greater (P<0.01). Conclusion Real-time B type ultrasound guidance used for low-grade gliomas resection could achieve good clinical results, significantly reduce the operation time and improve the patient’s quality of life.
