Disparities in anatomy between the novel CCFs and the typical traumatic CCFs. a The typical traumatic CCF has an intima-to-adventitia tear between the cavernous internal carotid artery (ICA) and the cavernous sinus (CS). b The novel CCF is composed of the ICA lumen, intimal entry, false channel, adventitial exit, and CS. c The concept of “self-expanding stent graft” means the use of native in situ dissection flap as covering membrane of the self-expanding stent to reconstruct true channel of the spiral dissection and simultaneously obliterate the novel CCF
