Three Cases of Newly Developed Paraplegia After Repairing Type A Acute Aortic Dissection

Postoperative paraplegia after repairing type A acute aortic dissection has been rarely reported and the causes have not been clearly elucidated. We had three cases of newly developed paraplegia after repair of type A acute aortic dissection. In these cases, we speculated that some intercostal arteries were occluded by completely thrombosed false lumen with late onset of systemic hypotension, which might have reduced spinal cord perfusion followed by paraplegia.
