Accuracy of transcranial color-coded duplex sonography in predicting clinical vasospasm and delayed cerebral ischemia in patients with subarachnoid hemorrhage

Cerebral vasospasm (VSP) and delayed cerebral ischemia (DCI) play a central role in worsening the neurological outcome in patients with aneurismal subarachnoid hemorrhage (aSAH) [1]. Transcranial color-coded duplex sonography (TCCS) is a non-invasive tool to detect VSP and predict DCI, but its clinical utility is limited by low accuracy. Our aim was to perform a sensitivity/specificity analysis of TCCS in predicting clinical VSP and DCI.
