Innominate artery versus combined innominate and femoral artery perfusion in acute type A aortic dissection: a comparison of surgical efficiency and early outcomes
Clinical Report: Comparison of Innominate Artery Perfusion Strategies in ATAAD
Overview
This study compares isolated innominate artery antegrade perfusion (IA) with combined innominate and femoral artery perfusion (IA + FA) in patients undergoing surgery for acute type A aortic dissection.
Background
Acute type A aortic dissection (ATAAD) is a critical cardiovascular emergency with high mortality rates. Surgical intervention is essential, and the choice of perfusion strategy during cardiopulmonary bypass is crucial for organ protection and patient survival. This study evaluates two perfusion strategies.

Key Findings
The IA group had a significantly shorter total operative time compared to the IA + FA group (370.05 min vs. 397.26 min, p = 0.04).
No significant differences were found in 30-day mortality between the two groups (10.71% vs. 21.05%, p = 0.28).
Postoperative complications such as cerebral infarction and acute kidney injury showed no significant differences between groups.
Numerical trends favored the IA group for rates of re-sternotomy and new requirement for hemodialysis.
Clinical Implications
The findings suggest that isolated innominate artery antegrade perfusion may enhance surgical efficiency in ATAAD procedures. Clinicians may consider IA as a preferred strategy to reduce operative time while maintaining safety outcomes.
Conclusion
Further validation in larger studies is warranted.
