Overview

Analysis predicts mid-term outcomes in patients post frozen elephant trunk surgery, suggesting timely interventions.

Key Points

  • To evaluate if early aortic remodeling identified by CT predicts mid-term outcomes after FET surgery for chronic aortic dissection.
  • Analyzed data from 56 patients undergoing total arch replacement with FET at two centers.
  • Measured changes in aortic diameter using CT at 6 months post-surgery.
  • Classified patients based on early remodeling patterns as either EPR or ENR.
  • Tracked outcomes including distal reintervention, dSINE, and overall survival over a 5.4-year follow-up.
  • 64% of patients required distal reintervention by the end of follow-up.
  • Freedom from distal reintervention was significantly higher in EPR patients (44.6%) compared to ENR patients (6.2%).
  • dSINE occurred in 46.4% of the cohort, with EPR showing a 65.1% freedom rate compared to 18.2% in ENR.
  • Overall 5-year survival was 80.0%, with drastic differences between ENR management strategies.
