PURPOSE: Achieving a secure anastomosis and complete hemostasis is essential for surgically treating type A acute aortic dissection (TAAAD). This study assessed the clinical feasibility of "tailored stand-up collar (TSC)" technique for constructing the distal stump.
METHODS: We enrolled 68 patients who underwent ascending aortic repair for TAAAD. Patients were categorized according to the technique for distal stump construction: conventional (C) group using only a felt strip (32 cases); post-aortotomy (P) group, with a Hydrofit-felt strip attached after aortotomy (18 cases), and TSC group, where a Hydrofit-felt strip attached during cooling (18 cases). Pre-operative characteristics, procedural profiles, and post-operative outcomes were evaluated.
RESULTS: The pre-operative characteristics were identical among the groups. The durations of cardiopulmonary bypass, hemostasis, and surgery were significantly shorter in the P and TSC groups. The duration of open distal in the TSC group (21 min) was significantly shorter than the other two groups. Post-operative additional procedures were not required for the TSC group and their post-operative hospital stay was significantly shorter (47.1% of patients were discharged within 2 weeks).
CONCLUSION: The TSC technique would be practical because of its high reproducibility in terms of ease of use, shorter anastomotic time, and secure hemostasis.
