Condition: Diabetic Foot Ulcers (DFU) · Lower Extremity Arterial Occlusion · Sponsor: Shenyang Medical College
Critical limb ischemia is the end-stage manifestation of peripheral arterial disease (PAD), frequently presenting as ischemic rest pain, ulceration, or gangrene. Diabetes mellitus is a major risk factor for lower extremity arterial occlusion, with infrapopliteal arteries most commonly affected. Patients with diabetic foot ulcers (DFUs) have a high prevalence of neurovascular complications, poor healing, and elevated amputation and mortality rates. Large-scale cohort studies indicate that five-year survival after amputation in this population is only about 50%, underscoring the need for more effective therapies. Endovascular revascularization has become the first-line treatment for diabetic lower limb ischemia. However, despite successful revascularization, persistent microvascular dysfunction and difficult-to-heal ulcers remain common due to chronic inflammation, impaired angiogenesis, and tissue repair deficits. Current advanced wound dressings provide limited benefit and are often costly. Cold atmospheric plasma (CAP) has emerged as a promising adjunctive therapy, with demonstrated antimicrobial activity-including efficacy against multidrug-resistant organisms-and the ability to promote microcirculation and wound healing. CAP generates reactive oxygen and nitrogen species that disrupt bacterial membranes and may also stimulate tissue regeneration. Preclinical and clinical studies suggest that CAP can accelerate healing in chronic wounds and is well tolerated by patients. …
