[Complicated with Spinal Cord Injury After Frozen Elephant Trunk Procedure for Stanford Type A Acute Aortic Dissection].

We report two cases complicated with spinal cord injury after the frozen elephant trunk procedure for Stanford type A acute aortic dissection. The two patients experienced dissection from the ascending aorta to the iliac arteries, and posterior false lumens were seen from Th8 to L2 in both cases. After an emergent surgery, both patients showed paraplegia and underwent immediate spinal fluid drainage. Symptoms improved to paraparesis in both patients, who were subsequently transferred to rehabilitation hospital. If a posterior false lumen is present from Th8 to L2, an increased risk of complications by spinal cord injury following the frozen elephant trunk procedure should be considered.
