In Nevelle's Retrospective Study 2009, what was the failure rate when wounds were directly revascularized?

• A. 38.1%
• B. 9.1%
• C. 0%
• D. 25%

Answer: (B)

The key idea here is how restoring blood flow to a wound affects healing. Direct revascularization brings arterial blood supply back to ischemic tissue, which improves oxygen, nutrients, and immune response needed for the wound to heal. In Nevelle’s Retrospective Study from 2009, the observed failure rate when wounds were directly revascularized was 9.1%. This relatively low failure rate suggests that revascularizing the wound site can lead to a favorable chance of healing in many cases.

Other given figures don’t align with the study’s findings: a much higher failure rate would imply poorer outcomes, and a zero percent failure rate is unlikely in clinical practice. The 9.1% figure is the one reported, reflecting the benefit seen when direct revascularization is effectively applied in appropriate wounds.
