Abstract: | Transcranial doppler sonography is a diagnostic tool that allows the noninvasive study of intracranial circulation. In patients with aneurysmal subarachnoid hemorrhage, cerebral vasospasm is promptly diagnosed, even before clinical related symptoms. Feeding arteries of an arteriovenous cerebral malformation can be detected and their variations can be correlated to the treatment (neurosurgical and/or neuroradiological). When raised intracranial pressure (namely in head trauma), transcranial doppler sonography depicts vasospasm and/or typical variations of the waveforms, suggesting intracranial circulatory arrest. |
