Clinical Trial Summary

This study investigates whether, compared to standard treatment, immediate restoration of blood flow (revascularization) can reduce complications and improve diabetic foot ulcer healing.


Clinical Trial Description

Background: In approximately 80% of diabetes-related lower extremity amputations, patients suffer from a foot ulcer, often caused by lower extremity arterial disease. Due to lower extremity arterial disease (LEAD), diabetic patients with foot ulcers often require lower limb amputation. Achieving arterial supply (revascularization) to the ulcer is the most important factor in healing the diabetic foot ulcer and reduces the risk of amputation. The current standard of care recommends revascularization after six weeks in patients with low-grade arterial disease of the lower extremities and nonhealing foot ulcer. The aim of this study is to demonstrate that in patients with low grade arterial disease of the lower extremities and diabetic foot ulcers, immediate revascularization results in fewer cardiovascular problems and amputations, as well as improved ulcer healing, compared to the current standard of care. Study procedure: After inclusion in the study, participants will be randomized into the control arm or the active arm. In the control arm standard wound care will be performed. In the active arm, revascularization will be performed on top of standard wound care within 7 days after randomization. Post-revascularization analysis on ankle- and toe pressure, laboratory analysis, and wound care team assessment and therapy will be performed 24 h post operation. Follow up will be on 45, 90, 180 and 365 day for patients of both arms, where ankle- and toe pressure, laboratory analysis, and wound care team assessment and therapy will be performed. Number of Participants: 240 participants in total, 120 per treatment arm Study duration: 4 years Study Centre(s): International multi-centre study with approximately 8-12 centres Participating countries: Switzerland, Germany ;
