Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Vascular Surgery

Background:

  • Aortic arch surgery traditionally involves perfusion interruption, leading to increased risks.
  • The branch-first continuous perfusion aortic arch replacement (BF-CPAR) technique aims to mitigate these risks.

Purpose of the Study:

  • To describe the BF-CPAR technique.
  • To report midterm outcomes of BF-CPAR over a 15-year period.

Main Methods:

  • Analysis of 155 patients undergoing BF-CPAR from July 2005 to February 2021.
  • Evaluation of demographic, procedural, and outcome data (mortality, reintervention, morbidity, stroke).
  • Application of Kaplan-Meier and Cox regression for survival and event analysis.

Main Results:

  • 10-year freedom from aortic death was 95.6% (elective) and 93.3% (emergency).
  • 10-year freedom from any aortic reintervention was 72.8% (elective) and 29.2% (emergency).
  • 10-year freedom from cerebrovascular events was 82.6% (elective) and 75.4% (emergency).

Conclusions:

  • BF-CPAR demonstrates excellent 10-year results for both elective and emergency aortic arch replacement.
  • The technique effectively overcomes the limitations of traditional aortic arch surgery.
