Temporal tap manoeuvre

Temporal tap manoeuvre consists in tapping over the ipsilateral temporal artery while assessing the carotid bifurcation on Doppler ultrasound aiming to produce a reflected flow in the external carotid artery (ECA) and thus helping to distinguish which vessel is being assessed: external vs. internal carotid artery (ICA) 1.

It is only relevant when anatomical distortions and technical limitations preclude a confident labelling of the ICA or ECA. The manoeuvre has shown to be limited and not always reliable, as the reflected flow can sometimes cal also be detected in the ICA 2.
