Abstract:
Objective:To evaluate Castor single-branch covered-stent in the treatment of Stanford B aortic dissection(TBAD)with insufficient anchorage zone.Methods:Clinical data of 25 TBAD patients (proximal healthy landing zone ≤15 mm) treated with Castor branched stent-graft at Weifang People's Hospital from Apr 2019 to Sep 2021 were analyzed retrospectively.The stent model was selected according to preoperative CTA examination and intraoperative angiography,the operation result and follow up data were reviewed.Results:The operation success rate was 100%,the mean operative time was (137.8±35.8)min, and the mean blood loss was (52.8±24.5)ml. There were 2 cases of internal leakage (IA) and it was disappeared after balloon dilation, Branched stent stenosis occurred in 2 cases and relieved by balloon dilatation. The mean follow-up time was 14.6 months, and the patency rate of branch stent was 100% during the follow-up period. The true lumen diameter of thoracic aorta was significantly expanded and the false lumen diameter was significantly reduced 3 months after surgery compared with that before surgery ( P<0.05). Conclusion:Castor stenting in the treatment of TBAD with insufficient proximal anchoring area is simple and feasible, with satisfactory short term clinical effect.
