Bicarotid Trunk: How Much Is “Not Uncommon”?

The prevalence of bicarotid trunk of 17.6% among patients with aortic coarctation and 15.2% among the entire population studied made it not at all a rare phenomenon. Because bicarotid trunk can be a risk factor for surgery, the anatomy of the aortic arch needs to be clearly depicted and described. If ultrasonography examination cannot exclude bicarotid trunk, enhanced magnetic resonance imaging or aortic arch angiography may be necessary.
