Clinical application of double-ring sandwich method in the root of acute A-type aortic dissection
Objective To analyze the efficacy and safety of double-ring sandwich procedure in the treatment of acute A-type aortic dissection root.Methods The clinical data of 103 patients with acute A-type aortic dissection treated by double-ring sandwich procedure in our center from October 2020 to May 2023 were retrospectively analyzed to investigate the surgical effect,short-term cardiac structural changes and short-term postoperative complications.Results Needle hemostasis was applied in 11.65％of all patients.The amount of red blood cell transfusion during the perioperative period was(2.95±1.97)U,plasma was(543.68±208.48)ml,and blood platelet was(0.08±0.30)U.The residual aortic regurgitation,cardiac function and pericardial effusion were significantly improved at 2 weeks after operation(P＜0.05).The proportion of residual false lumen in the aortic root was significantly reduced after operation(P＜0.05).The length of hospital stay,duration of intubation,and drainage within 24 hours after surgery were less.The incidence of postoperative short-term complications such as secondary thoracotomy,cerebral infarction,cerebral hemorrhage,hemofiltration,tracheal incision and death was low.Conclusions Double-ring sandwich procedure in the treatment of acute A-type aortic dissection can effectively block the false lumen of aortic root dissection,reduce the risk of aortic intimal avulsion,and the operation is safe and effective.
