Pitfalls of the aortic arch view

The principal pitfall consists of confusing the aortic arch with the ductal arch. The origins of the aortic arch are posterior and inferior giving it the form of a candy cane, very regular and with a small radius.

Opposite to this, the origin of the ductal arch, more anterior and superior to the PA, leaves it appearing more horizontal.

The aortic arch is identified by the departure of three vessels from the arch.

The confusion between these two elements can be simplified, especially at the end of pregnancy when the relative overload of the right tract causes it to be elevated, often situated above the aortic arch. If there is the slightest doubt, you should concentrate on showing the existence of the origin of the vessels of the neck, thus identifying the aortic arch.
