Recruiting studies
- NCT07561320RecruitingPhase 4
Two ways to treat enlarged veins in your leg
This study compares two minimally invasive procedures to treat enlarged great saphenous veins (a vein in your thigh that can cause swelling, pain, or skin changes). Both procedures seal off the problematic vein by either using heat and mechanical motion or injecting a foaming substance.
São Paulo, São PauloAges 18 years+ - NCT06711120Recruiting
Comparing two treatments for varicose veins in the lower legs
This study compares two minimally invasive treatments (radiofrequency ablation and microwave ablation) for varicose veins in the small saphenous vein. If your varicose veins cause symptoms like pain, swelling, or heaviness, this trial may help determine which treatment works better.
ChengduAges 18–90 - NCT07276243Recruiting
Foam plus laser for varicose veins
This study tests if adding a laser to a foam treatment (polidocanol) works better for varicose veins than the foam alone. It may help people with small to medium varicose veins that are close to the skin.
Rio de Janeiro, Rio de JaneiroAges 21–75 - NCT07317492Recruiting
Hemorrhoids and varicose veins study
This study looks at the connection between hemorrhoids and varicose veins. It may help researchers understand if these conditions are related and how to better treat them.
Aydin, EfelerAges 18 years+ - NCT07570277Recruiting
Nursing Support for Leg Vein Surgery Recovery
This study tests whether specialized nursing guidance helps patients recover better after surgery for varicose veins (enlarged veins in the legs). The nursing support focuses on helping you manage your own care at home after surgery.
Nanchang, Jang XIAges 18 years+ - NCT07449728Recruiting
Laser treatment for varicose veins with different wavelengths
This trial tests different types of laser energy to treat varicose veins. It looks at which wavelength works best for closing the faulty vein and preventing the disease from getting worse.
MoscowAges 18 years+ - NCT07334028Recruiting
Timing of infrared imaging for varicose veins
This study uses a special camera to take pictures of your leg veins at different times to find the best moment for imaging. It may help improve how varicose veins are diagnosed.
Guildford, SurreyAges 18 years+ - NCT05663359Recruiting
Compare two laser treatments for varicose vein reflux
This trial tests whether a 1940 nm or a 1470 nm laser works better for treating varicose veins in the legs. It may help you find a more effective option to reduce vein problems like swelling, heaviness, and visible bulges.
ToulouseAges 18 years+ - NCT06971068Recruiting
Vacuum-assisted laser treatment for large leg veins
This study tests a new laser treatment that uses a small vacuum to remove large varicose veins in the legs. It may help people with big, uncomfortable veins that other treatments might not work as well for.
MinskAges 18–90 - NCT06124664Recruiting
Study of leg vein drainage in pelvic varicose veins
This study looks at how blood flows from the legs in people with varicose veins in the pelvis. It may help doctors understand the link between pelvic and leg vein problems.
MoskvaAges 18–40 - NCT06693245Recruiting
Pain during microwave treatment for varicose veins
This study looks at how much pain people feel during a microwave treatment for varicose veins in the leg. It aims to understand what factors affect pain, so the treatment can be more comfortable for future patients.
Chengdu, SichuanAges 18–90 - NCT04487314Recruiting
Study of chronic vein disease over time
This study follows people (and certain close family members) to document how chronic vein problems develop and change over time. You would get yearly checkups and ultrasound scans to track the natural course of the condition.
Saint PetersburgAges 10 years+ - NCT03035747Recruiting
Registry for treatment of varicose veins
This study collects information about people who have varicose veins with abnormal backflow in the leg veins. It’s meant to track how treatments for chronic venous problems are working over time, which can help improve care for others in the future.
Saint PetersburgAges 18 years+ - NCT03416413RecruitingPhase 4
Compare two treatments for varicose vein leakage
This trial tests whether foam sclerotherapy or a small-surgery treatment (ambulatory phlebectomy) works better for symptoms from leaking varicose veins. It may help by improving which option is most effective and comfortable for people like you.
LondonAges 18 years+ - NCT05735639RecruitingPhase 4
Prevention of blood clots during varicose vein treatment
This trial tests whether giving medicine to prevent blood clots during varicose vein treatment is safe and helpful. It focuses on people having a minimally invasive procedure on enlarged leg veins under local anesthesia.
LondonAges 18 years+ - NCT03041805Recruiting
Check whether a clot-risk score predicts recovery after vein surgery
This study looks at how well a clot-risk score (Caprini score) relates to blood clot checks and outcomes after varicose vein surgery. You may be asked to have an ultrasound scan a few weeks after your operation and be followed for about 4 weeks.
MoscowAges 18 years+ - NCT07624929Enrolling by invitation
Virtual Reality to Reduce Anxiety During Varicose Vein Treatment
This study tests whether wearing a virtual reality headset during varicose vein treatment (a minimally invasive laser procedure on your legs) can help reduce anxiety and pain. You'd use VR while the doctor treats the problematic veins under local anesthesia.

- How do I know if I qualify for a varicose veins trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a varicose veins trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
