[The change of blood supply pattern in visceral arteries of Stanford B dissection after endovascular repair].
OBJECTIVE
To discuss the change of blood supply pattern in visceral arteries of Stanford B dissection. The visceral arteries include celiac trunk (CA), superior mesenteric artery (SMA) and renal artery (RA).


METHODS
By retrospectively analysing the clinical data of 52 cases with Stanford B dissection, the blood supply pattern of visceral arteries was confirmed by aortography and the changes before and after endovascular repair were compared.


RESULTS
After repair: the stenosis lesions disappeared in 7 cases supported by true channel completely but one. Twenty-two visceral arteries supported by true and false channel simultaneously recovered true channel chiefly but one. One recovered true channel chiefly and one had no change in 2 visceral arteries supported by false channel completely. Four recovered true channel chiefly and one had no change in 5 visceral arteries without blood support. 88.9% blood support got better and 11.1% blood support had no change in 36 damaged visceral arteries after endovascular repair.


CONCLUSIONS
Blood support from true and false channel simultaneously is the chief pattern in the injured visceral arteries before repair; Endovascular repair technique is benefit to recovering the blood support of true channel.
