Active clinical trials for "Varicose Ulcer"

The venous ulcer due to venous insufficiency causes an important morbility to those people suffering from this condition. Most of therapies available under the obligatory health plan (POS, acronym in spanish) to date cover the cleaning of the ulcerous lesion and its medical handling using saline solutions, topical antibiotics and elastic dressings, implying an important intake from health resources due to its chronicity and the delay in ulcers healing, which usually takes periods ranging from 6 months to several years. therapeutical alternatives, which can guarantee optimal, fast and persistent in time healings, should be identified. The aim of this study is to determine the percentage of healing of active venous ulcers (using a clinical, etiological, anatomic and physiopathologic classification (CEAP), C6) following ultrasound-guided foam sclerotherapy of superficial venous reflux in patients with chronic venous ulceration after six months from the intervention, compared with conservative medical handling. The investigators expect that the ultrasound-guided foam sclerotherapy of superficial venous reflux will diminish the time of ulcer healing compared with standard handling.

This study seeks to demonstrate the performance of Negative Pressure Wound Therapy on chronic wounds such as diabetic foot ulcers and venous leg ulcers. The primary objective of the study is to demonstrate the performance and safety of Avelle Negative Pressure Wound Therapy on wound and wound fluid management when used in accordance with the instructions for use. Participation in the study is anticipated to be two weeks. The Avelle™ NPWT System will be used for two weeks and participants will be seen for study visits during this time. Study participants will need to visit the doctor's office up to five times and, at a minimum, will be required to see the health care provider three times, dependent on the condition of the wound. Each visit is anticipated to last for approximately 45 to 60 minutes.

Pilot study of a soft, flexible pressure and temperature sensor

This study was undertaken to identify prospectively which clinical venous leg ulcer (VLU) characteristics known as possible prognostic markers, and which sociodemographic and psychologic factors associated with VLU are associated with complete healing at 24 weeks.

OASIS Wound Matrix (Oasis) will be applied to wounds, with sequential biopsy of healing wounds to explore the mechanism of action.

This is a 24-week observational follow safety study for Study 802-247-09-015.

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.

Varicose veins of lower extremities can lead to adverse consequences such as ulceration and hemorrhage, which seriously endangering the physical and mental health and quality of life for patients. The aim of this study is to explore the potential risk factors of venous ulceration in patients with varicose veins of lower extremities based on a case-control study, and to provide a reference for personalized treatment.

Chronic venous ulceration of the lower limb poses a significant problem to patients and healthcare providers alike. 1% of the population of Western countries have either an open or healed chronic venous ulcer. However, the pathophysiological abnormalities are not entirely clear in how raised venous pressure translates into the changes seen in the skin culminating in an open ulcer. The standard treatment of this condition in the United Kingdom is to undertaken compression bandaging of the lower limb. In order to further their knowledge of venous ulceration, the investigators seek to determine the biological profile of venous ulcers over a maximum of twenty-eight weeks and by dividing the groups into healing and non-healing wounds, the investigators may be able to demonstrate a difference in the biological profile. This work may provide insights into predicting who will respond to treatment and targets for treatment in the future.

Leg ulcers are frequent. There are no epidemiological studies available in France, but international studies estimate the prevalence between 0.045 and 0.63% of the total population, prevalence increases with age, reaching 5% of patients over 80 years. Extrapolating these prevalences in the French population between 28 000 and 395 000 people are affected in France a leg ulcer. It is a costly disease. In 2001, a French study conducted among 800 physicians, including 85.7% of general practitioners, involving more than 1000 patients with venous ulcers, it was estimated that the total cost of treatment per patient average was 888 32 euros. This is truly a public health problem. Leg ulcers are in 80% of cases of vascular causes (venous, arterial or arteriovenous mixed). However, there are rare causes of ulcers: skin carcinoma, infectious ulcers and vasculitis. These ulcers rare causes require specific treatments that can often heal. To diagnose, to perform a skin biopsy. Thus, the general practitioner must know when to put the indication for biopsy of a leg ulcer.
