Abstract：Objective To study the effect of castor branch covered stent(castor stent)in Standford type B aortic dissection(TBAD)involving the left subclavian artery(LSA)and its influence on aortic remodeling.Methods A total of 58 TBAD patients admitted to Wuxi Mingci Cardiovascular Hospital were divided into castor group(31 cases)and control group(27 cases)based on treatment methods.The control group received chimney technology,while the castor group received castor stents for treatment.The surgical related indicators and perioperative complications between the two groups were compared.The incidence of late complications such as upper limb ischemia,cerebral infarction,internal leakage,LSA steal,and dissection reverse tearing during the follow-up period between the two groups were compared.The aortic remodeling indicators between the two groups at 2 weeks and 6 months after surgery were compared.Results The fluoroscopy time and surgical time in the castor group were longer than those in the control group(P＜0.05).The incidence of perioperative complications in the castor group was lower than that in the control group(P＜0.05).The incidence of late complications during follow-up in the castor group was lower than that in the control group(P＜0.05).At 6 months after surgery,the false lumen complete thrombosis rate in the castor group was higher than that in the control group(P＜0.05).Conclusion Although castor stent treatment involves longer TBAD fluoroscopy time and surgical time for LSA compared to chimney technology,the incidence of perioperative and late complications are lower,and it helps patients with false lumen thrombosis.
