Temporal artery tap: usefulness and limitations in carotid sonography

WebFeb 24, 2024 · The ECA will display a higher resistance waveform with low flow velocity during diastole. When the ICA is stenosed or occluded, the ECA can provide collateral flow to the brain, and the morphology of the ECA waveform can reflect low resistance flow and be confused with the morphology of the ICA waveform. Because the ECA has low flow … Webwaveform demonstrates significant continuous forward flow throughout diastole. There is normal, laminar flow without spectral broadening, and the peak systolic velocity is typically <100 cm/s. (C) In contrast, the Doppler waveform of the external carotid artery (ECA) has a sharp systolic increase, rapid decrease in flow toward grimy person https://pkokdesigns.com
