Abstract
ObjectiveTo explore the aortic remodeling after thoracic endovascular aortic repair for acute type stanford B aortic dissection.
MethodsRetrospective analysis the clinical data of 51 patients who diagnosed with acute type B aortic dissection and received TEVAR between September 2015 and August 2016. The maximal diameters of false and true lumen were measured directly at the level of primary tear entry, the level of the bronchial bifurcation, and the level of the celiac trunk and the the lower edge of left renal artery, changes in diameter were evaluated between the preoperative and postoperative CT scan.
ResultsThe marked change in the true lumen dilatation and false lumen regression trend at the level of primary tear entry after thoracic endovascular repair(1 month vs 1 year, P<0.05), while the changes of its diameter above level were not obvious after thoracic endovascular repair(3 months vs 6 months, P>0.05). the true lumen dilatation and false lumen regression trend at the level of the bronchial bifurcation along with time. The true lumen dilatation is a process of slow change at the level of the celiac trunk and the lower edge of left renal artery after TEVAR, and the false lumen changed not obviously.
ConclusionEndografting is effective for acute type B aortic dissection which can promote positive descending aortic remodeling changes, but it has no significant effect on abdominal aortic remodeling.
