Summary
This study presents an improved surgical technique for total aortic arch replacement, demonstrating low mortality and morbidity rates. The approach ensures favorable long-term survival for patients undergoing this complex cardiovascular procedure.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Vascular Surgery
Background:
- Total aortic arch replacement is a complex procedure with significant risks.
- Advancements in surgical techniques are crucial for improving patient outcomes.
Purpose of the Study:
- To present recent advancements in total aortic arch replacement using a specific surgical approach.
- To evaluate the safety and efficacy of this technique in a large patient cohort.
Main Methods:
- 321 patients underwent total aortic arch replacement via median sternotomy between 2002-2010.
- Key techniques included selective cerebral perfusion, controlled hypothermia, and specific drug/fluid management protocols.
- Patient demographics included a mean age of 69.8 years, with 28.3% having aortic dissection and 33.0% requiring emergency/urgent surgery.
Main Results:
- Overall hospital mortality was 4.4%, with 1.9% in elective cases.
- Permanent neurologic deficit occurred in 4.4% of patients (2.8% in elective cases).
- 3- and 5-year survival rates were 82.4% and 78.5%, respectively; risk factors for mortality included octogenarian status, brain malperfusion, and cardiopulmonary bypass time.
Conclusions:
- The presented approach for total aortic arch replacement is associated with low hospital mortality and morbidity.
- This technique offers favorable long-term outcomes for patients requiring aortic arch surgery.
