Acute Type A Aortic Dissection with Iliac Malperfusion in a Patient with Scimitar Syndrome.

We encountered a 35-year-old male patient with scimitar syndrome, acute type A aortic dissection, and severe iliac malperfusion. He presented with pain and weakness of the left lower extremity and underwent ascending aorta replacement through sternotomy and right anterior thoracotomy. Left iliac artery flow was recovered after the operation and the patient was discharged on the tenth day without any complication. The purpose of this report is to discuss the considerations in aortic surgery in patients with scimitar syndrome, and the surgical principles for treatment of aortic dissection with critical limb ischemia.
