Why diabetes-related foot ulcers fail to heal despite successful revascularization: closing the patency-to-healing gap: a narrative review.
Diabetes-related foot ulcers are a serious complication where wounds on the foot do not heal, sometimes leading to amputation. Even when blood flow is restored through a procedure called revascularization, many ulcers still fail to heal. This review looked at why this 'patency-to-healing gap' exists by examining scientific studies on the topic. The authors found that successful revascularization does not guarantee healing because other factors, such as infection, pressure on the foot, and poor nutrition, play a major role. They also highlighted that the quality of the newly restored blood flow, especially in tiny vessels, is crucial. The review suggests that a comprehensive approach, including infection control, offloading pressure, and optimizing wound care, is essential. However, this is a narrative review, not a primary study, so it lacks direct patient data. For patients, this means that even after successful surgery to restore blood flow, ongoing multidisciplinary care is vital for wound healing.
Key takeaways
- Revascularization restores blood flow but does not guarantee ulcer healing; a 'gap' often remains due to other factors.
- Ongoing infection, pressure on the foot, and nutritional status are critical for healing even after successful revascularization.
- The quality of blood flow in small vessels matters as much as large vessel patency.
- Patients should ask their doctor about a comprehensive care plan including infection control and offloading devices.
- Even if blood flow is restored, be prepared for continued wound care and follow-up to promote healing.

Editor's note
Think of revascularization like fixing a clogged main pipe that brings water to your garden, but if the tiny sprinklers are still broken, or the soil is poor, your plants won't thrive. This research shows that fixing the big blood vessel is just the first step; your wound also needs a clean environment, no pressure on it, and good nutrition to truly heal. If you've been told your wound won't heal or amputation is the only option, this is a hopeful message: a team that treats the whole problem, not just the blood flow, can still help you heal. In China, leading diabetic foot centers already use this comprehensive approach, so as an international patient, you can seek out a center that offers not only revascularization but also specialized wound care, infection management, and offloading therapy—making your chances of saving your foot much higher.
