Near infrared spectroscopy is a valuable tool to monitor cerebral oxygenation during intracranial interventions. However, it yields artificial results when the dye indocyanine green (ICG) is applied, which is routinely done for intraoperative angiography. The investigators examine, to what extent and which duration NIRS is disturbed following ICG application.

RECRUITINGamount of rSO2 - change [%] induced by ICG-application
Cerebral oxygenation (rSO2) may be quantified using NIRS. The dye ICG, that is used intraoperatively, affects NIRS, since it changes rSO2 without modifying cerebral oxygenation. The amount, by which rSO2 is altered will be assessed
