Carotid imaging

The right and left carotid bifurcations usually look like this


Maybe it’s the way the the bilateral dorsal aortas resolve into an asymmetric arch, but there is asymmetry in the carotid arteries which lets me look at a lateral carotid arteriogram and reliably predict which carotid artery it is. Image I is the usual conformation of the right ICA takeoff which may be tucked ,medially and posteriorly toward the pharynx. Image II is the typical forked appearance of the left ICA, and because it is longer and the plaque usually ends at the bend, this makes an eversion easier on that side. I began noticing this when I was on the CVRx trial applying stimulator leads on the carotids.
