title: [Transcranial Doppler in neurosurgery. A non-invasive method in the diagnosis of vasospasm and subarachnoid hemorrhage].
abstract: Transcranial Doppler (TCD) sonography, a noninvasive method to record cerebral blood flow velocity, is increasingly being used to predict the development of a delayed ischemic deficit after subarachnoid hemorrhage. Advantages and limitations of the TCD technique in neurosurgical practice are discussed.
