Lower extremity bypass (LEB) surgery outcomes

What is lower extremity bypass surgery?

Lower extremity bypass (LEB) surgery is needed when arteries become blocked and keep blood from flowing to the legs and feet, which can cause pain. During this surgery, surgeons create a new pathway that goes around the blocked artery to restore blood flow to the lower leg and foot.

What does this measure show?

This measure tracks patients who experienced serious problems or death within 30 days of having lower extremity bypass surgery. It is based on a sampling method developed by the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP).

Serious problems from LEB surgery can include heart attack, infections, blood clots, stroke, pneumonia, kidney failure, breathing support needs.

The rate of serious problems or death for LEB surgery patients is shown as an odds ratio. This reports the estimated odds of a serious problem or death occurring at Northwestern Memorial compared to the estimated odds of the same serious problem occurring in all hospitals in the ACS NSQIP database.

In this case, a lower number is better.
