Diabetic Foot Ulcer Graft

To report a review and meta-analysis of all randomized controlled trials (RCTs) comparing bypass surgery (BS) and endovascular treatment (ET) in infrainguinal peripheral arterial disease (PAD) for several endpoints, such as major and minor amputation, major adverse limb events (MALEs), ulcer healing, time to healing, and all-cause mortality to support the development of the Italian Guidelines for the Treatment of Diabetic Foot Syndrome (DFS). A MEDLINE and EMBASE search was performed to identify RCTs, published since 1991 up to June 21, 2023, enrolling patients with lower limb ischemia due to atherosclerotic disease (Rutherford I-VI)...

OBJECTIVES: To compare the efficacy of negative pressure wound therapy (NPWT) and alginate dressings on wound bed preparation prior to split thickness skin graft (STSG) surgery for patients with chronic diabetic foot ulcers (DFUs). METHODS: Between September 2022 and March 2023, we completed a randomized controlled trial in Nanjing First Hospital and PLA 454 Hospital. Patients were divided into 2 groups: i) the NPWT group (with vacuum-assisted closure, n=50); ii) the control group (with alginates dressings, n=50)...

Significance: Chronic wounds affect 10.5 million (up 2.3 million from the 2014 update) of U.S. Medicare beneficiaries. Chronic wounds impact the quality of life of nearly 2.5% of the total population of the United States. This fraction is larger in the elderly. These wounds can lead to a range of complications and health care costs. Given the aging population, the continued threat of diabetes and obesity worldwide, and the persistent problem of infection, it is expected that chronic wounds will continue to be a substantial clinical, social, and economic challenge...

In modern practice, xenografts play a crucial role in wound management due to their regenerative properties. Of the various xenografts currently available on the market, acellular fish skin (AFS) grafts have emerged as a more effective alternative to existing xenografts and other standard of care (SOC) treatments for wound healing. Since AFS grafts require minimal processing, they maintain their structural integrity and natural properties, including an abundance of Omega-3 fatty acids, which is a distinctive, pro-regenerative feature...

Platelet-rich plasma (PRP) has been recognized as a method of treatment in medicine since the 1980s. It primarily functions by releasing cytokines and growth factors that promote wound healing; these growth-promoting factors released by PRP enact new processes such as angiogenesis, collagen deposition, and tissue formation that can change wound-healing outcomes. Many studies recognize that PRP aids in chronic wound healing, which is advantageous for patients who suffer from chronic diabetic foot ulcers (DFUs)...

Chronic wounds such as diabetic foot ulcers and venous leg ulcers place a significant burden on the healthcare system and in some cases, have 5-year mortality rates comparable to cancer. They negatively impact patients' quality of life due to pain, odor, decreased mobility, and social isolation. Skin substitutes are an advanced therapy recommended for wounds that fail to show decrease in size with standard care. The choice of substitute used should be based on evidence, which often differs based on wound etiology...

BACKGROUND: Diabetic foot ulcers (DFUs) are common in patients with diabetes, especially those undergoing hemodialysis. In severe cases, these ulcers can cause damage to the lower extremities and lead to amputation. Traditional treatments such as flap transposition and transfemoral amputation are not always applicable in all cases. Therefore, there is a need for alternative treatment methods. CASE SUMMARY: This report describes a 62-year-old female patient who was admitted to the hospital with plantar and heel ulcers on her left foot...

AIM: To explore the therapeutic efficacy of autologous wound edge-dotted full-thickness skin grafting in improving diabetic foot ulcer healing. METHODS: Sixty-three patients were divided into three groups: conventional wound therapy (CWT) (n = 23), platelet-rich plasma (PRP) (n = 20), and graft (n = 20). All participants were followed up for 12 weeks. The therapeutic efficacy of the three different wound treatment modalities was analyzed. RESULTS: After follow-up, 37 (58...

Split-thickness skin grafts can provide effective autologous wound closure in patients with dysvascular comorbidities. Meshing the graft allows for reduced donor site morbidity and expanded coverage. This study directly compares outcomes across varying meshing ratios used to treat chronic lower extremity wounds. Patients who received split-thickness skin grafts to their lower extremity for chronic ulcers from December 2014 to December 2019 at a single center were retrospectively reviewed. Patients were stratified by meshing ratios: nonmeshed (including pie crusting), 1...

Diabetic foot ulcers are a significant complication of diabetes, affecting millions globally, and require appropriate antibiotics, surgical debridement, wound care, and metabolic optimization for management. This article presents an innovative hybrid regenerative therapy for reconstructing an infected, traumatized foot wound of a 62-year-old man with diabetes mellitus who presented with a week-old injury after a car accident. At presentation, he had a 14 × 10 cm dorsal foot wound with skin necrosis, pus discharge, and bony instability owing to partial fractures and joint dislocations...

A non-healing diabetic foot ulcer (DFU) is a debilitating clinical problem amounting to socioeconomic and psychosocial burdens. DFUs increase morbidity due to prolonged treatment and mortality in the case of non-treatable ulcers resulting in gangrene and septicemia. The overall amputation rate of the lower extremity with DFU ranges from 3.34% to 42.83%. Wound debridement, antibiotics, applying growth factors, negative pressure wound therapy, hyperbaric oxygen therapy, topical oxygen, and skin grafts are common therapies for DFU...

INTRODUCTION: Arthrodesis is an expensive procedure that is less applicable in developing countries. In this case report we reported a case of diabetic charcot neuroartropathy (CN) with primary ankle arthrodesis technique with a fibular strut graft which is considered cheaper and has a higher union rate. CASE DESCRIPTION: A 47 years old female with complaints of pain in her right ankle after falling down the stairs with foot inverted one month before admission...

Limb salvage options are limited in diabetic patients with critical limb ischemia. Soft tissue coverage remains technically demanding with limited recipient vessels for free tissue transfer. These factors make revascularization alone challenging. When open bypass revascularization is possible, venous bypass graft is optimal and functions as a recipient vessel for staged free tissue transfer.The authors present 2 cases using a combination approach of staged venous bypass graft revascularization followed by free tissue transfer with anastomosis to the venous bypass graft resulting in successful limb preservation...

Significance: With the increasing diabetic population worldwide, diabetic foot ulcers (DFUs) are a significant concern. This study aimed to compare the efficacy of skin substitutes, biomaterials, and topical agents with standard care. Recent Advances: A meta-analysis was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed, EMBASE, and Web of Science were searched using the following keywords: diabetes mellitus AND skin graft OR tissue replacement OR dressing OR drug...

The development of biomaterial platforms for dispensing reagents of interest such as antioxidants, growth factors or antibiotics based on functional hydrogels represents a biotechnological solution for many challenges that the biomedicine field is facing. In this context, in situ dosing of therapeutic components for dermatological injuries such as diabetic foot ulcers is a relatively novel strategy to improve the wound healing process. Hydrogels have shown more comfort for the treatment of wounds due to their smooth surface and moisture, as well as their structural affinity with tissues in comparison to hyperbaric oxygen therapy, ultrasound, and electromagnetic therapies, negative pressure wound therapy or skin grafts...

Chronic inflammation and hypoxia in the microenvironment of diabetic foot ulcers (DFUs) can result in sustained vascular impairment, hindering tissue regeneration. While both nitric oxide and oxygen have been shown to promote wound healing in DFUs through anti-inflammatory and neovascularization, there is currently no available therapy that delivers both. We present a novel hydrogel consisting of Weissella and Chlorella , which alternates between nitric oxide and oxygen production to reduce chronic inflammation and hypoxia...

Few studies to date have investigated the role of adipose derived stem cells (ADSCs) in patients with diabetic foot ulcers (DFU). We aimed to conduct a systematic search of the literature to explore the available evidence behind ADSCs application in patients with DFU to establish if it has any added benefit regarding healing rate and healing time in this cohort of patients. The PubMed and Embase databases were searched for eligible studies. Only randomised controlled trials which investigated the impact of ADSCs alone on the healing of DFU were considered eligible and were included for the review...

PURPOSE: The purpose of this study was to determine whether a single-use negative pressure wound therapy (NPWT) system achieves individualized goals of therapy when used to treat patients with a variety of wound types. DESIGN: Multiple case series. SUBJECTS AND SETTING: The same comprised 25 participants; their mean age was 51.2 years (SD: 18.2; range: 19-79 years); 14 were male (56%) and 11 were female (44%).
