False lumen–dependent segmental arteries are associated with spinal cord injury in frozen elephant trunk procedure for acute type I aortic dissection

  SCI occurrence in the FL-dependency group was obviously more than FL-independency group.

  Figure 1. Three categories of SA origination. A, SAs completely from FL at the Th9-L3 level. B, SAs partially from FL at the Th9-L3 level. C, SAs completely from TL at the Th9-L3 level. FL, False lumen; TL, true lumen.

  Figure 2. Occurrence time of postoperative SCI. SCI, Spinal cord injury; FL, false lumen; SA, segmental artery.

  Figure 3. A graphical summary of our study. The FL dependency of SAs at T9-L3 levels was significantly associated with the occurrence of SCI following aortic arch replacement and FET implantation in AAD. FL, False lumen; AAD, acute aortic dissection; FET, frozen elephant trunk; SA, segmental artery; SCI, spinal cord injury.
