Surgical identification of brain tumour margins through impedance monitoring and electrocorticography and the potential for their combined use: a systematic review

HIGHLIGHTS

• What: Of note, four studies reported continuous monitoring as the probe was transversing different tissues while the rest reported single point measurements either before or after the tumour resection . The studies aimed to define how neural circuits are altered in the presence of brain tumours , with some observing the hyperexcitable environment CNS tumours induce and one exploring its relationship with spreading depolarisation (SD) . This highlights an intrinsic limitation of the tools used in studies in this review regarding temporal resolution, compared to techniques such as 5-ALA that allow for synchronous visualisation of the tumour border.
