- Normal arch sidedness sweep
- Bifurcation of the brachiocephalic trunk at the end of the sweep demonstrating right subclavian artery and right common carotid artery
- Left sided aortic arch with a normal branching pattern
- Normal left aortic arch with a normal branching pattern
- Normal color Doppler flow within the aorta and head and neck vessels
- Bifurcation of the brachiocephalic trunk at the end of the sweep demonstrating right subclavian artery (blue flow) and right common carotid artery (red flow)
- Normal laminar flow noted in the innominate vein and superior vena cava
The sweep from the suprasternal notch determines arch sidedness. As you sweep up toward the patient's neck, the first branch of the aorta (brachiocephalic trunk) should travel toward the patient's right and bifurcate (into the right subclavian artery and right common carotid artery) as you continue your sweep high into the neck.
- Probe placed in suprasternal notch
- Notch at 3 o'clock
- Sweep superiorly and towards patient's right shoulder while following aorta
- Right aortic arch
- Left aortic arch with aberrant left subclavian artery
- Any anomaly of arch branching
- Vascular ring
