    This study compared isolated innominate artery antegrade perfusion (IA) and combined innominate and femoral artery perfusion (IA + FA) in ATAAD surgery.

  • 2

    The study involved 94 ATAAD patients, with 56 in the IA group and 38 in the IA + FA group, focusing on surgical efficiency and short-term outcomes.

  • 3

    Total operative time was significantly shorter in the IA group (370.05 min) compared to the IA + FA group (397.26 min), with no significant differences in mortality.

  • 4

    Safety outcomes, including 30-day mortality and major complications, showed no significant differences between the two groups, though trends favored the IA group.

  • 5

    The findings suggest that IA may be a more efficient first-line perfusion strategy for ATAAD surgery, with IA + FA reserved for specific cases.
