To evaluate the early remodeling of proximal aorta in patients with acute type B aortic dissection (ATBAD) after zone 2 thoracic endovascular repair (TEVAR).From January 2016 to May 2022, 53 ATBAD underwent TEVAR were divided into two groups, Castor single-branched stent-graft (CSS) group (n = 26) and common 27). Three-dimensional imaging created by computed tomography angiography was used measure different parameters aorta, such as angulation, cross-sectional area (CSA), length tortuosity. Early evaluated comparing geometric before 3 months surgery.In terms angle, postoperative angle arch ascending descending increased all compared that surgery (all P < 0.05), while left subclavian artery only CSS (P 0.001); As for CSA, CSA distal true lumen false decreased both groups operation 0.05); Only group, total In length, prolonged 0.018 0.004, respectively). addition, tortuosity 0.011). There no significant difference alterations other > 0.05).The implantation provided a more relatively safe effective treatment unfavorable landing zone. It can promote earlier TEVAR.
