Abstract:
Objective:To investigate the effect of different stent oversize in thoracic endovascular aortic repair (TEVAR) on lumen remodeling of type B aortic dissection (TBAD).Methods:The clinical and follow-up data of 89 TBAD patients receiving TEVAR from Nov 2010 to Jun 2020 at Yantai Yuhuangding Hospital were retrospectively analyzed. According to the difference of proximal stent oversize, 89 patients were divided into: low oversize group (<10%, 47 cases) and high oversize group (≥10%, 42 cases). The changes of the normal vessel diameter and area at the proximal end of the stent and the long diameter, short diameter and area of the true/false lumen at the distal end of the stent at 3, 6, and 12 months after surgery and postoperative complications were analyzed.Results:The change of proximal vessel diameter with time in the low oversize group is smaller than that in the high oversize group ( P<0.05),and the change of the distal false lumen area of the stent in the low oversize group was greater than that in the high oversize group ( P<0.05). The high oversize group was prone to retrograde type A aortic dissection (RTAD) ( P<0.05). Conclusion:Low oversize stents are more conducive to the remodeling of the aortic lumen in the early and mid-term after TEVAR in TBAD patients.
