Study of Foam Sclerotherapy Versus Ambulatory Phlebectomy

This study is looking at two common ways to treat those lumpy, bulging veins in your legs, often called varicose veins. Specifically, it compares foam sclerotherapy, which involves injecting a special foam, with ambulatory phlebectomy, a minor procedure to remove them. Both treatments are used for the smaller "tributary" veins that branch off the main ones. We want to see which treatment works best, considering things like how often the veins come back, how safe each method is, how patients feel about their experience, and which one is more cost-effective. People taking part will be randomly assigned to receive either the foam injection or the mini-surgery after their main vein has already been treated.

What is this study about?

This study is designed to help us understand the best way to treat a common problem called varicose veins. These are veins, usually in your legs, that have become swollen, twisted, and sometimes lumpy or bulging. Many people get them, and while they can be just a cosmetic concern, they can also cause aching, discomfort, or itchiness.

After the main vein causing the problem is treated (for example, by sealing it off), there are often smaller, branching veins, called 'tributaries,' that also need attention. This study focuses on comparing two well-known treatments for these smaller veins: foam sclerotherapy and ambulatory phlebectomy.

Foam sclerotherapy involves injecting a special foam into the vein. This foam irritates the lining of the vein, causing it to close up and eventually fade away. Ambulatory phlebectomy is a minor surgical procedure where a doctor makes tiny nicks in the skin and removes the problematic vein segments. By comparing these two methods, we hope to find out which one is more effective in the long run, safer, more comfortable for patients, and better value for money. This will help doctors offer the best treatment options to people with varicose veins in the future.

Key takeaways

  • Compares two treatments for branching varicose veins: foam injections and small surgery.
  • Aims to find out which treatment works best, is safest, and offers the best patient experience and cost.
  • Participants will be randomly assigned to one of the two treatment groups.
  • Involves follow-up appointments and questionnaires to gather information.
  • Helps improve future treatment for people with varicose veins.

Who may be eligible?

This study is open to adults aged 18 and over who have varicose veins and are experiencing symptoms. Specifically, your main leg veins (called the GSV or SSV) must show signs of a problem where blood isn't flowing correctly, and you must have bulging varicose veins that need treatment.

There are certain reasons why you might not be able to join the study. For example, if you currently have a blood clot in your leg (DVT), have had varicose veins treated before, or have very poor circulation in your arteries, you wouldn't be able to take part. Also, if your veins are very small (less than 3mm), or if you already strongly prefer one treatment over the other, you might not be eligible.

Finally, you need to be willing and able to fill out questionnaires, attend all follow-up appointments, and not be involved in another varicose vein treatment study at the same time.

Could this study suit you?

Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.

  1. Are you 18 years old or older?
  2. Do you have symptomatic varicose veins in your legs?
  3. Have you been told you need treatment for a main leg vein problem and also for its branches?
  4. Are you able and willing to attend follow-up appointments and fill out questionnaires?
  5. Have you NOT had varicose veins treated before?
  6. Do you NOT currently have a blood clot (DVT)?
Answer every question to see your result.

What does participation involve?

If you decide to take part in this study, you would first have your main varicose vein treated. After that, you would be randomly assigned to receive either foam sclerotherapy or ambulatory phlebectomy for your smaller, branching veins. This is like flipping a coin, ensuring a fair comparison between the two treatments.

Throughout the study, you would attend several appointments for assessments. These will include checking your veins with an ultrasound scan, discussing your comfort and any symptoms you have, and filling out questionnaires about your experience and how you feel. The doctors will also keep track of your safety and how well the treatment is working. The exact number and timing of visits will be explained to you in detail.

Potential risks and benefits

Participating in this study might offer you faster access to a treatment for your varicose veins. You'll receive either foam sclerotherapy or ambulatory phlebectomy, both of which are established treatments that could relieve your symptoms and improve the appearance of your legs. However, as with any medical procedure, there are potential risks, such as bruising, swelling, temporary discomfort, or, less commonly, other side effects. These will be fully explained before you decide to take part. Importantly, you are free to withdraw from the study at any time, for any reason, without it affecting your usual medical care.

Common questions

What are varicose veins?

Varicose veins are veins, usually in the legs, that have become swollen, twisted, and sometimes lumpy or bulging because the valves inside them aren't working properly.

What is 'randomly assigned'?

Being 'randomly assigned' means you have an equal chance of receiving one of the two treatments being studied, like drawing lots or flipping a coin. This helps ensure fair results.

What is foam sclerotherapy?

Foam sclerotherapy involves injecting a special foam directly into the varicose vein. This foam makes the vein close up, causing it to shrink and eventually fade away.

What is ambulatory phlebectomy?

Ambulatory phlebectomy is a minor procedure where a doctor makes tiny nicks in the skin to carefully remove segments of the problematic varicose veins.

Will I know which treatment I'm getting?

Yes, once you are randomly assigned, your healthcare team will tell you whether you will receive foam sclerotherapy or ambulatory phlebectomy.
