Chronic venous insufficiency

This trial asks whether adding ozone gel to ultrasound treatment helps chronic venous leg ulcers heal better than either treatment alone. Venous leg ulcers are open sores that occur when leg veins fail to return blood to the heart, and they can be slow to heal. Researchers will c…

This trial tests whether a personalized tissue-engineered vein, made in the lab with a functioning valve, can safely replace a damaged vein segment in people with severe chronic venous insufficiency. Each participant undergoes surgery to swap a non-working valve in their femoral …

This study tested a new way to treat venous leg ulcers, which are slow-healing wounds on the lower leg. Researchers used ultrasound to push hyaluronic acid gel into the wound and compared it to standard care in 64 patients. The goal was to see if this combination speeds up healin…

This study tested a special wound dressing called MicroMatrix Flex on 25 adults with deep or tunneled wounds, such as pressure injuries, diabetic ulcers, or infected wounds. The goal was to see how safely and quickly the dressing helped close these wounds over 12 weeks. Researche…

This study tested whether an AI app (IVENUS) could correctly classify the severity of chronic vein disease from leg photos. Over 1,600 patients had their legs photographed, and the app's diagnosis was compared to that of experienced doctors. The goal was to see if the app could r…

This study tested a device called Insight Pro to see if it can safely detect lymphatic and vein disorders, such as lymphedema and chronic venous insufficiency. The device measures fluid buildup and skin hardness in the arms or legs. A total of 67 adults with or without these cond…

This trial tests whether a short 5-day course of the blood thinners rivaroxaban (Xarelto) or apixaban (Eliquis) can prevent blood clots that sometimes form after laser treatment for varicose veins. Adults with symptomatic vein reflux undergoing laser ablation of the great sapheno…

This trial tests whether a structured nursing program—including education before the procedure, support during it, and follow-up calls—can improve symptoms and quality of life for people with chronic venous disease undergoing foam sclerotherapy. Participants are randomly assigned…

This study tested a new, standardized process for providing assistive devices (like special tools) to help people put on and take off compression stockings. 220 adults who need these stockings long-term took part. The goal was to see if the new method improves how often people us…

This study tested a dietary supplement containing diosmin, hesperidin, bromelain, and ruscus aculeatus in 80 adults with early signs of chronic venous disease, like heavy or swollen legs. Participants took the supplement for 12 weeks, and researchers measured changes in quality o…

This study tested two ways of applying compression bandages for venous leg ulcers: one that covers the heel and one that leaves it uncovered. Researchers measured the pressure under the bandage and checked ankle swelling in 102 patients. The goal was to see if leaving the heel ou…

This study tested a wearable compression device called Dayspring for people with lymphedema in one leg. 24 adults used the device daily for 3 months. Researchers measured changes in leg swelling and quality of life to see if the device was safe and helpful.

This study tested whether a combination of herbal ingredients (horse chestnut, polygonum acre, smilax pepyracea, and rutin) works as well as a standard drug (diosmin and hesperidin) for easing leg symptoms from chronic venous insufficiency. 120 adults with mild to moderate vein d…

This study tested a new portable, non-pneumatic compression device (Dayspring) against a standard pneumatic compression device for treating leg lymphedema. 121 adults with leg swelling used each device for three months, with a month off in between. Researchers measured changes in…

This study tested whether sleeping with a special leg-elevation device (UZit®) can ease symptoms of chronic venous disease, a condition where leg veins have trouble moving blood back to the heart. Seventeen adults used the device every night for one week. Researchers measured cha…

This study looked at whether a special interactive dressing (UrgoStart Plus) used with compression bandages can help heal venous leg ulcers faster than standard dressings. Sixty adults with chronic leg ulcers were treated for up to 12 weeks. The goal was to see if the new dressin…

This study investigates whether people with chronic venous insufficiency—a condition where leg veins struggle to return blood to the heart—experience more swelling, pain, and weakness than healthy people. Researchers will measure breathing muscle strength, lung function, walking …

This completed study looked at 26,000 patients who had outpatient procedures for blood vessel problems like peripheral artery disease, varicose veins, or dialysis access issues. The goal was to see how safe and effective these procedures are when done in an office-based angiosuit…

This study looked at whether combined oral contraceptives (birth control pills) influence the development or worsening of chronic venous diseases, like varicose veins. Researchers followed 116 women taking different types of birth control pills. The goal was to see if these pills…

This study looked at 650 Brazilian patients with chronic venous disease (CVD), a condition that causes leg swelling, skin changes, and ulcers due to faulty veins. Researchers collected data on risk factors like obesity and smoking, other health problems, and treatments used. The …

This study looked at how compression stockings of different strengths change the size and pressure of leg veins in people with chronic venous insufficiency and healthy volunteers. Researchers measured vein diameter and leg pressure while participants stood, sat, or lay down. The …
