Acute type A aortic dissection repair in younger patients

Area of Science:

• Cardiovascular Surgery
• Aortic Dissection Research
• Thoracic Aortic Disease

Background:

• Acute type A aortic dissection (AAAD) presents unique challenges in younger patient populations.
• Understanding long-term outcomes is crucial for optimizing treatment strategies in patients under 50.

Purpose of the Study:

• To evaluate the surgical outcomes and midterm results of patients under 50 years old who underwent repair for acute type A aortic dissection (AAAD).

Main Methods:

• Retrospective analysis of 51 patients under 50 who underwent AAAD repair between 2003 and 2016.
• Surgical procedures included total arch replacement (76.5%) or hemiarch replacement (23.5%), with 39.2% undergoing concomitant surgeries.
• Data collected on demographics, comorbidities, surgical details, and long-term follow-up outcomes.

Main Results:

• Low in-hospital mortality (2.0%) with 5-year and 10-year overall survival rates of 87.7% and 81.9%, respectively.
• Reoperation rates were 60.2% at 5 years and 50.2% at 10 years, with a patent false lumen being a significant risk factor (P < 0.001).
• Causes for reoperation included aortic dilatation, root dissection, infection, and hemolysis.

Conclusions:

• Surgical repair of AAAD in young patients demonstrates satisfactory midterm results.
• A patent false lumen is a significant predictor of reoperation but does not impact long-term survival.
• Mandatory close follow-up is essential for young patients post-AAAD repair to monitor for complications.
