Abstract
The detection of vasospasms was the first application of transcranial Doppler sonography. Even today, the sonographic detection and control of vasospasms is still part of the treatment regime of subarachnoid hemorrhage. At a mean flow velocity of 120 cm/s in the cerebral arteries a beginning vasospasm, at 160 cm/s a significant and at 200 cm/s a critical vasospasm can be assumed. With simultaneous intracranial pressure increase, the flow velocity decreases, which can lead to misinterpretations. In this case, the increase in pulsatility of the flow velocities is important for the diagnosis of vasospasm. Hyperperfusion can be distinguished from vasospasm by the MCA/ICA index.
