Assessment of the Posterior Communicating Artery by Transcranial Color-Coded Duplex Sonography Stroke 27:486-489, Klotzsch,C.,et al, 1996 See this aricle in Pubmed Article Abstract The aim of this study was to investigate flow velocity and flow direction in the posterior communicating artery(PcomA)by means of transcranial color-coded duplex sonography(TCCD)and to compare the results with angiographic findings.TCCD appears to be a valuable method to determine flow velocity and flow direction not only in the large intracranial vessels but also in the smaller communicating arteries.In the future this method could be useful for the planning of ICA balloon occlusions and in deciding whether to perform extracranial/intracranial bypass surgery.It could furthermore show intracranial collaterals in patients with cerebrovascular disease and help to estimate the risk of watershed infarctions in patients with asymptomatic high-grade ICA stenosis and in patients undergoing carotid endarterectomy.
