Neuronavigation in falcine meningiomasare surgery: Initial results from a Vietnamese multi-center study.

Abstract

Neuronavigation has been applied in neurocenters to help neurosurgeons plan the way to resect tumor totally and decline the neuro-injuries. This study aims to initially evaluate the result of microsurgery applying neuronavigation in treating falcine meningioma, which has not been reported comprehensively in Vietnam. This cross-sectional study enrolled 62 patients diagnosised with falcine meningioma and treated by applying neuronavigation in operation in Neurosurgery Department of Military Hospital 103 and Viet Duc University Hospital from July 2015 to March 2017. Patients were assessed complications as well as residual lesions. Evaluate surgical results when discharging from hospital according to Ojemann MD standard. Mean tumor volume was 67.37±66.61cm³ (range 6-370cm³). Unilateral access site was the most common with 85.48%. Mean surgery duration was 209.84±70.86min. There were 27 out of 62 patients (43.55%) need blood transfusion in surgery. Tumor volume had an impact on blood transfusion in operation with p=0.002. 82.26% of patients had total resection (Simpson I,II). There were 4.84% of patients having haemorrhage and 3 patients (4.84%) had wound infection after operation. Short-term outcome was evaluated according to Ojemann MD standard: good outcome was 67.74%, medium 17.74%, and poor outcome 14.52%. The application of neuronavigation and microsurgery enables surgeons to access falcine meningiomasare exactly, lessen the surgery duration, limit blood transfusion and complications after operation.
