    Objective: Intracranial vasospasm is an important cause of brain ischemia when associated to subarachnoid hemorrhage. Multimodal monitoring can detect brain flow decrease and patients with high risk to develop brain ischemic lesions. TCD can detect and measure vasospasm intensity in the large intracranial arteries. Usually the oximetry catheter is implanted in the area most likely to occur vasospasm, which is near of brain bleeding. It can measure brain tissue oxygen (PtiO2) in areas with oligoemia associated to vasospasm. They give support to plane treatment to improve brain blood flow in patients suffering brain vasospasm.
