Abstract:
Objective To explore the influence of different initial intimal tear positions on abdominal branch perfusion in Stanford B aortic dissection.Methods CTA data of 130 patients with Stanford B aortic dissection were reviewed retrospectively.The involved aortic branches (celiac trunk,superior mesenteric artery,bilateral renal artery) were classified into different types according to the degree of ischemia and perfusion damage,and their relationship with different initial intimal tear positions were also analyzed.Results There were 542 branches in 130 patients,in which 465 branches (465/542,85.79％) were ischemic,including 337 branches (337/542,62.18％) of dynamic ischemia and 128 branches (128/542,23.62％) of static ischemia,77 branches (77/542,14.21％) without ischemia.In ischemic branches,the perfusion in 69 (69/542,12.73 ％) of them were impaired and those of the other 396 branches (396/542,73.06 ％) were unimpaired.In all of the 69 branches of impaired perfusion,37 branches (37/69,53.62％) were dynamic ischemia and 32 branches (32/69,46.38％) were static ischemia,and the difference was no statistically significant (x2 =3.077,P =0.215).Furthermore,no significant impact was found in initial intimal tear positions on ischemic patterns (dynamic and static) or perfusion patterns (unimpaired and impaired;x2 =1.352,0.776,P=0.509,0.678).Conclusion Initial intimal tear positions has no significant impact on ischemia pattern or perfusion pattern of abdominal aortic branches.The evaluation of abdominal aortic branches is helpful for guiding surgery.
