AI Article Synopsis

  • Ultrasonography revealed a significant size difference in the common carotid arteries, with the right measuring 0.39 cm and the left at 0.70 cm, indicating the absence of the right internal carotid artery.
  • The bilateral ophthalmic arteries showed that blood was flowing normally towards the eyes (anterograde flow), but there was a 50% reduction in flow on the right side compared to the left.
  • Specific measurements indicated the right side had a peak systolic velocity (PSV) of 23.3 cm/s and end diastolic velocity (EDV) of 7.0 cm/s, while the left side had a PSV of 47.0 cm/s and EDV of

Article 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]).
