Continuous dynamic subcortical mapping using a suction monopolar device in a child: Case report and technical note

Abstract

Extent of resection is a very important prognostic marker in adult and pediatric brain tumors. Therefore, radical resections confer an oncological benefit. Resection of intra-axial tumors in proximity to eloquent regions requires intraoperative mapping and monitoring. Continuous subcortical mapping using a suction monopolar device has been recently described for adult tumors. This allows a real-time dynamic mapping of the advancing resection cavity walls, synchronized with the surgeon’s actions during resection. We describe the application of this technique in a child who presented with a rapidly increasing right parietal mass. It was resected using this dynamic mapping technique. This is the first such report of its use in a pediatric brain tumor. We also review the relevant literature briefly.

Pediatric Central Nervous System Tumors: State-of-the-Art and Debated Aspects

“…In pediatric neurosurgery where most of the supratentorial tumors are low grade lesions, the use of neuromonitoring helps in maximizing the extent of safe resection with least possible morbidity. Continuous, dynamic subcortical mapping with a suction monopolar device has recently been described ( 43 ).…”
