European Venous Registry

The European Venous Registry (EVeR) is collecting information from patients across different countries about their experiences with deep vein disease in the legs. This isn't a new treatment trial, but rather a long-term study that follows people after they receive standard treatments for severe blood clots or blockages in their deep veins (like in the thigh or tummy area). The main goal is to see how different treatments perform over a ten-year period. By gathering this real-world information, doctors hope to learn what works best, helping them make better decisions about care for future patients. If you have been newly diagnosed with a specific type of deep vein problem and are aged 18 or over, you might be able to take part.

What is this study about?

Imagine a big, shared notebook where doctors from many hospitals write down how people with certain deep vein problems are treated and how they get on afterwards. That's essentially what the European Venous Registry (EVeR) is. It's not testing a new medicine or procedure, but rather observing how patients typically do with the treatments they already receive.

The main aim of this registry is to collect a lot of information over a long time – up to ten years – from people with serious deep vein issues in their legs, or sometimes in the main vein leading to the heart. This involves conditions where the major veins in the thigh or tummy are affected by clots or blockages. By carefully tracking many patients, the doctors running this registry hope to build a much clearer picture of which treatments are most effective and safe in the long run.

This kind of study is really important because it helps medical professionals make better decisions based on real-life experiences, not just controlled experiments. The information gathered from people like you can lead to improved care for everyone with deep vein disease in the future. It helps doctors understand the long-term effects of different ways of treating these conditions, ultimately aiming to improve patient health and quality of life.

Key takeaways

  • This study collects information, it's not a treatment trial.
  • It focuses on deep vein problems in the upper leg, tummy, or main body vein.
  • Aims to understand long-term effects of existing treatments (up to 10 years).
  • Helps improve future care for deep vein disease patients.
  • Participation involves sharing medical records, no new treatments or tests.
  • You can stop participating at any time.

Who may be eligible?

This study is looking for people who have recently been diagnosed with a specific type of deep vein problem. This means you would have a blood clot or blockage in the major, deep veins of your upper leg (thigh) or possibly in your tummy area, or even the main vein that goes to your heart. This diagnosis would need to be confirmed by scans.

To join, you must be aged 18 or older and be able to understand and agree to have your information included in the registry. It's important that your deep vein problem affects these specific large veins, and isn't just in the lower parts of your leg, or only affects surface veins.

You would not be able to join if you can't give your consent, if your deep vein clot is only in your arm, or if you only have varicose veins or clots in the surface veins. Similarly, if your deep vein clot is only below your knee, this study would not be the right fit.

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. Do I have a new diagnosis of a deep vein problem in my upper leg or tummy area?
  2. Has a scan confirmed this diagnosis?
  3. Am I aged 18 years or older?
  4. Can I understand and agree to have my medical information shared with the registry?
Answer every question to see your result.

What does participation involve?

If you choose to take part in this registry, it won't change your standard medical care or treatment in any way. You won't be given any new or experimental medications or procedures. What it does involve is allowing the study team to collect information about your existing deep vein condition and the treatments you receive as part of your normal care.

This data will be gathered from your hospital records, and you may be asked to attend follow-up appointments, or fill out questionnaires, as part of your regular check-ups. The study aims to follow participants for up to ten years to understand the long-term impact of their condition and treatment. There are no additional visits or medications involved beyond what your doctor already recommends for your care.

Potential risks and benefits

Taking part in this study does not involve any additional risks beyond your usual medical care, as it's purely about collecting information on standard treatments. The main benefit is that the information you contribute will help doctors better understand deep vein disease and improve treatment for future patients. There are no direct personal benefits from participating. You are free to withdraw your consent and stop participating in the registry at any time, without it affecting your medical care.
