5 Key Takeaways

• 1

  A study of over 1 million Medicare beneficiaries found no long-term survival difference between multi-arterial and single-arterial grafting.

• 2

  The research utilized a surgeon preference approach to account for unmeasured confounding factors affecting surgical outcomes.

• 3

  Initial findings suggested improved survival with multi-arterial grafting, but demographic differences were significant between grafting types.

• 4

  The study's results align with the Arterial Revascularization Trial, which also showed no significant survival difference between graft types.

• 5

  Researchers noted that their findings should not discourage multi-arterial grafting, emphasizing the importance of surgeon judgment in conduit selection.
