Kontinuierliches subkortikales Mapping zur Überwachung der Pyramidenbahn bei der Entfernung von motorisch eloquent gelegenen Hirntumoren

Zusammenfassung

Die moderne neurochirurgische Onkologie verfolgt das Konzept der maximalen Tumorentfernung mit gleichzeitiger Funktionserhaltung. Dies ist bei Gliomen eine Herausforderung, da Tumorgrenzen nicht immer sichtbar sind und anatomische Landmarken verschoben sein können. Im folgenden Artikel werden intraoperative neurophysiologische Methoden zur Lokalisation und Überwachung des Primär Motorischen Kortex und der Pyramidenbahn in der supratentoriellen Tumorchirurgie diskutiert.

Abstract

In modern neuro-oncological surgery, the key concept is maximal but safe tumor resection. However, this is a surgical challenge as tumor borders may be invisible, and anatomical landmarks might be distorted. In this review, we discuss intraoperative neurophysiological monitoring and mapping methods to identify the primary motor cortex and corticospinal tract in supratentorial tumor surgery.
