Brief Summary:
The purpose of this study is to show if it is possible to detect secondary ischemic events in patients with severe brain injury or cerebral haemorrhage with the help of non-invasive near-infrared spectroscopy (NIRS) by using the indocyanine green measuring of cerebral perfusion.

Arm Intervention/treatment
Experimental: indocyanine green
in this arm we do the Intervention 'measuring cerebral perfusion by NIRS with ICG', the pat. gets before a CT-Scan with perfusion measurement a indocyanine green bolus i.v. and a measurement of cerebral perfusion with near-infrared-spectroscopy
Procedure: measuring cerebral perfusion by NIRS with ICG
application of a bolus of 5mg indocyanine green (ICG) in 3ml saline 0,9% i.v. in 1 second and measuring the ICG turnover with the near-infrared-spectroscopy (NIRS)
Other Names:
  • indocyanine green
  • NIRO-200NX C10488, Hamamatsu Photonics K.K.

Primary Outcome Measures :
  1. with near-infrared-spectroscopy detected cerebral perfusion deficit [ Time Frame: 15 days after ictus ]

Secondary Outcome Measures :
  1. Determining a threshold value for cerebral autoregulation measured with near-infrared-spectroscopy as a predictive value for the clinical outcome [ Time Frame: 15 days after ictus and follow up 6 month later ]
