Abstract

(Upper panels) Ultrasonography showed caliber difference of common carotid arteries (right side: 0.39 cm; left side: 0.70 cm) for right internal carotid artery agenesis. (Lower panels) Bilateral ophthalmic arteries showed anterograde flow with 50% flow reduction over right side (right: peak systolic velocity, PSV [23.3 cm/s]; end diastolic velocity, EDV [7.0 cm/s]; left: PSV [47.0/s] EDV [14.2 cm/s]).

Keywords: internal carotid artery agenesis; ultrasonography.
