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]).

摘要

（上图）超声显示右侧颈总动脉（右侧：0.39cm；左侧：0.70cm）管腔差异，提示右侧颈内动脉发育不良。（下图）双侧眼动脉均显示正向血流，右侧血流减少 50%（右侧：收缩期峰值流速 PSV[23.3cm/s]；舒张末期流速 EDV[7.0cm/s]；左侧：PSV[47.0/s]，EDV[14.2cm/s]）。
