This single-center retrospective study analyzed 353 consecutive patients who underwent Zone 1 aortic arch repair with the Frozenix Open Stent-Graft (Japan Lifeline, JAPAN) between July 2014 and December 2023. This procedure shows promising long-term results with acceptable mortality and complication rates. The higher survival rate in the re-intervention group suggests that careful followup and timely re-intervention may improve long-term outcomes.  From January 2024, J-graft 4 Branched Spiral with Frozenix is used to achieve one-stage treatment for acute aortic dissections.
