Ascending Sliding Arch Aortoplasty for Coarctation of the Aorta and Hypoplastic Aortic Arch to Avoid Compression of a Retroaortic Innominate Vein.

The retroaortic innominate vein variant usually courses asymptomatically. However, when associated with coarctation of the aorta and hypoplastic aortic arch, modifications in the surgical technique to correct the aorta should be done to avoid compression of the vein. The ascending sliding arch aortoplasty, which allows the vein to be brought anterior to the aorta, can be a good alternative, as shown in these two cases.
