Derivatin of a Risk Prediction Score for Late Aortic Events in Uncomplicated Stanford Type B Aortic Dissection

Abstract

15 (1+ in 8; 2+ in 5; 3+ in 2), and no organisms could be detected in 7. When abscess formation around FF occurred, 2 -3 sutures were removed, and drainage with lavage was continued for 2 e 6 weeks. FF re-suturing was necessary to prevent further dehiscence and FF swelling. The FF was fixed to the implantation floor, NPWT was applied.Results -There were 8 FF losses due to vessel complication, and 2 failing FFs due to vein graft stenosis. Of 8, 5 underwent successful redo FF. In redo FF, proximally long FF covering vessel pedicle and short vessel pedicle using aDVA were used to prevent vessel thrombosis, and 2-SO was effective to avoid inflow failure. Scapular FF were preferably used because of less calcified artery. FF partial dehiscence due to abscess formation occurred in 10 due to residual osteomyelitis or wound infection. Of 10, 9 were DM/HD, and remaining one was uncontrolled DM. Preoperative infection control reduced organisms, but was ineffective to prevent FF infection. FF failure occurred in 3, while remaining 7 achieved successful FF healing by the local management (Table).Conclusion -CBFF for ETL was effective LS option. However, vein thrombosis of FF was common cause of FF loss, and DM/HD frequently occurred FF infection. Long FF and short pedicle using aDVA were effective to prevent vessel thrombosis, and intensive local management with a fixation suture was effective on FF infection.
