Summary
The Branch-first continuous-perfusion aortic-arch replacement (BF-CPAR) technique offers a safer alternative for aortic arch repair, significantly reducing mortality and stroke risks, especially in elective cases. This method enhances patient outcomes by minimizing circulatory arrest and ischemic times during complex aortic surgeries.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- Aortic arch surgery poses higher risks due to perfusion interruption.
- The Branch-first continuous-perfusion aortic-arch replacement (BF-CPAR) technique is presented to mitigate these risks.
- This study details the technique, outcomes, and improvements associated with BF-CPAR.
Purpose of the Study:
- To evaluate the safety and efficacy of the BF-CPAR technique over a 15-year period.
- To compare outcomes based on etiology (aneurysm vs. dissection) and urgency of intervention.
- To identify predictors of mortality, stroke, renal failure, and end-organ ischemia.
Main Methods:
- Retrospective analysis of 155 patients undergoing BF-CPAR from July 2005 to February 2021.
- Outcomes stratified by aneurysm and dissection etiology.
- Multivariable logistic regression used to predict adverse events.
Main Results:
- Overall mortality was 4.5% and stroke rate was 3.2% in 155 patients.
- Elective cases showed significantly lower mortality (0.0%) and stroke (1.9%) compared to urgent cases.
- Predictors for mortality included age; for stroke, hypercholesterolemia and hypertension; for dialysis, dissection.
Conclusions:
- BF-CPAR is a safe and effective technique for aortic arch repair.
- The technique demonstrates excellent outcomes, with no mortality and low stroke rates in elective and uncomplicated acute dissection cases.
- Improved results are attributed to avoiding cerebral circulatory arrest and reducing ischemic times.
