Filter by:The aim of this trial is to determine if fat grafting may have applicability to venous ulcers by comparing healing and recurrence rates in patients who receive combined fat grafting and endovenous ablation with patients who receive endovenous ablation only
In this study, investigators aim to use fat grafting in patients with previously healed venous ulcers to study its role on increasing skin thickness and reconstructing skin layers which was damaged by venous hypertension and determine its impact on reducing recurrence rates at 1 year
CACIPLIQ20® is currently a class III CE marked medical device available in various European and non-European countries, and currently primarily used in managing hard-to-heal wounds. This study is a prospective and standardized recording of patients' data followed in real-life conditions to appreciate the benefits of a therapeutic strategy including CACIPLIQ20® use. It also aims at collecting data to follow-up the device's efficacy and safety and estimate its cost-effectiveness.
To evaluate the efficacy and safety of Cytori Celution System in Hungarian patients with chronic non-healing venous leg ulcers.
Evaluation of the efficacy (wound epithelialization and time to closure) and safety (emergence and nature of adverse event) of the new URGO BD001 compression system versus a reference compression in the local treatment of venous or mixed predominantly venous leg ulcers: prospective multicenter, randomized controlled, open-label clinical study
Chronic Venous Disease (CVD) is a widespread clinical condition widely spread in the western countries that may negatively impact the quality of life (QoL) of affected patients. Chronic venous leg ulcers (CVLUs) are the most severe form of CVD, and several genetic and molecular alterations have been studied in order to understand the progression of CVD towards CLVUs. Chronic inflammation is a key element in CVLUs onset, and recently T helper 17 (Th-17) cells, a subtype of pro-inflammatory T helper (CD4+) cells defined by the production of a cytokine signature of which IL-17 represents the progenitor, seem to be related to several chronic disease. The aim of this study is to evaluate Th17- Gene Expression profile in patients with CVD and CVLUs.
The main purpose of this exploratory clinical investigation is to study the binding of bacteria and fungi from hard-to-heal wounds to the DACC-coated dressings.
This study will evaluate the effects on venous blood flow of the investigational device, OsciPulse system, which is an external intermittent limb compression device. The study will enroll healthy human subjects who will have their deep venous blood flow measured by vascular ultrasound during immobility, use of the OsciPulse system, and use of two reference vascular compression devices. Our hypothesis is that the OsciPulse system will create distinct patterns of venous flow, specifically at the site of venous valves, in comparison to the reference compression devices.
Leg ulcers are areas of epidermal discontinuity in lower limbs with causes of venous, arterial, diabetic, pressure, traumatic, allergic, or inflammation. Chronic venous leg ulcers (VLUs) are defined as leg ulcers persisting for 4 weeks or more, a.k.a C6 in CEAP classification of chronic venous insufficiency (CVI) and account for up to 70% of all chronic leg ulcers exhibiting overall prevalence of up to 2% in the general population of western countries with significant morbidity and a negative socioeconomic impact. Wound care, debridement, bed rest with leg elevation, and compression are basic approaches for chronic VLUs. Meanwhile, numerous medical and surgical interventions were developed to promote wound healing and to prevent recurrence by focusing on pathophysiology of chronic VLUs. However, many strategies just have adjuvant effects or exert debatable benefits. The lymphatic system been considered important for removal of excessive fluid from the interstitial space, absorption of fat from the intestine and the immune system, actively involved in regulation of immune cell trafficking and inflammation. Emerging lymphovenous bypass (LVB), a supermicrosurgical technique diverting lymphatic drainage into venous system in dealing with lymphedema, not only restores TH1 and TH2 imbalance, but decreases oxidative stress and increases antioxidant capacity in the serum of lymphedema patients. Clinically, LVB could be an alternative treatment option for patients with lymphorrhea. Based on these facts, the investigators hypothesis that lymphatic hypertension and lymph impregnation contributes chronic venous leg ulcer formation and propose a novel strategy, using LVB to treat patients with refractory/recurrent chronic VLUs. The preliminary results revealed promising results and the investigators would go on clinical trials.
The objective of this study is to compare the efficacy of a daily geko™ wound therapy (duration of 12 hours), in conjunction with standard of care (SC), to SC alone, in participants with venous leg ulcers.The participants will go through a four-week run-in phase, followed by a four-week treatment phase and a three-month long term follow-up.
