Cardiologist said aneurysm external and internal carotid very rare in neck and rare inside sternal head andjugular notch no ultrasound needed ?true?

Carotid thoughts: I assume there are no symptoms. Aneurysms are rare but do occur. See: http://www.sciencedirect.com/science/article/pii/S0741521400498800 Why not instead worry about garden variety plaque/stenosis in a 49 yo and try for a screening carotid U/S? No harm in a screening U/S, but may not be so available in the UK. Would advise if a signif. history of smoking or family history of vascular disease.
