A Complicated Case of Innominate Artery Avulsion and Subsequent Aorto-subclavian Graft Occlusion

: A 41-year-old female presented with complaints of right arm claudication, weakness, and pain associated with serous drainage from a previous incision site to the right anterior chest. At age 16, this patient was involved in a motor vehicle accident, which resulted in a right innominate artery and brachiocephalic vein avulsion. The two vessels were immediately ligated and oversewn. The perfusion to her right arm was supplied by cerebral collateral circulation down the right vertebral to the right subclavian artery.
