From: Right aortic arch analysis – Anatomical variant or serious vascular defect?
a Computed Tomography Angiography of the aortic arch, transverse scan of 51 y.o. woman with several stenoses of the right common carotid artery - compression between the aortic arch and sternoclavicular joint (gray arrow). The left common carotid artery has a normal lumen (red arrow). The left subclavian artery in aberrant configuration (white arrow). b Doppler ultrasound Spectrum of left common carotid artery confirmed typical flow Systolic velocity about 80 cm/s diastolic velocity 35 cm/s. c Doppler ultrasound Spectrum of right common carotid artery confirming severe stenosis in the proximal part of the artery. Systolic velocity is low, about 45 cm/s, diastolic velocity 35 cm/s
