Aberrant right subclavian artery in blunt aortic injury: implication for treatment and review of the literature.

Blunt aortic injury (BAI) involving an aberrant right subclavian artery (ARSA) is uncommon. The presence of an ARSA entails several treatment issues, in particular regarding the risk of perioperative posterior cerebral stroke. We report the case of a man with an ARSA who suffered from BAI. An initial conservative treatment with delayed open repair was chosen. A review of the published literature with discussion of the case is presented. The presence of an ARSA in patients with BAI can be considered a poor anatomy for endovascular repair, and suitable patients may benefit from delayed open repair.
