Abstract:
Spinal cord ischemia (SCI) after surgery for acute type A aortic dissection is rare, and delayed paraplegia is particularly uncommon. A 76-year-old woman underwent emergency partial arch replacement for acute type A aortic dissection. Preoperative computed tomography scan showed that multiple intercostal arteries originated from the false lumen. On postoperative day 3, she developed acute paraplegia. Imaging demonstrated complete thrombosis of the false lumen, and spinal magnetic resonance imaging confirmed SCI. When spinal arteries originate from the false lumen, rapid thrombosis after entry closure may compromise spinal cord perfusion and lead to delayed SCI.
