[Acute spinal cord ischemia following surgery for DeBakey type-1 dissection of the ascending aorta].

We describe the case of a 68-year-old man seen in the emergency room for sudden piercing chest pain radiating toward the back. The electrocardiogram and analytical parameters were normal; however, the chest x-ray showed mediastinal widening. The chest and abdominal computed tomography (CT) revealed DeBakey type 1 aortic dissection and TTE showed severe aortic regurgitation. The patient underwent emergency surgery. The entry site was at the origin of the left subclavian artery, with retrograde progression to the aortic valve and anterograde progression toward the thoracic aorta. Under deep hypothermia and antegrade cerebral perfusion, the ascending aorta and aortic arch were replaced, with reimplantation of the supraaortic branch and aortic valve resuspension. There were no complications in the postoperative care unit and the patient was discharged at 48 h.
