The V-REGISTRY and Artificial Intelligence: understanding real-world data in phlebology

Go back to Archives (FR)


This page is not a technical manual and it does not provide medical advice.

Its aim is to explain, in simple terms, what the V-REGISTRY project is and how artificial intelligence (AI) is starting to interact with venous and lymphatic data.

In recent years, phlebology has seen:

  1. the development of international registries collecting real-world data on venous and lymphatic diseases, such as the V-REGISTRY, promoted by the v-WIN foundation;
  2. the growing interest in AI tools that can analyse large datasets and support diagnosis or risk stratification in venous pathology.

On phlebo-online.org, we present these evolutions as background information for clinicians, students and interested patients, without telling anyone which test, treatment or technology they should receive.

The information on this page is general and educational.
It does not replace a consultation with a doctor, phlebologist, angiologist or any other healthcare professional.
Only a health professional who knows your situation can decide which examinations or treatments are appropriate for you.


What is a “registry” in phlebology?

In medicine, a registry is a structured database that collects information about real patients seen in everyday practice. In phlebology and lymphology, registries can include:

  1. clinical characteristics (age groups, symptoms, comorbidities),
  2. types of venous or lymphatic disorders,
  3. treatments performed in real life,
  4. outcomes and follow-up data when available.

Unlike a single clinical trial, a registry aims to reflect real-world practice: different countries, different centres, different ways of working. This is precisely the spirit of projects such as V-REGISTRY, described as a global vein-lymphatic database connecting multiple regions and congresses.

For clinicians and researchers, these registries can help to:

  1. better understand how venous and lymphatic diseases are managed in daily practice;
  2. identify patterns and trends that may not appear in smaller datasets;
  3. support the development of guidelines and quality-of-care initiatives.


The V-REGISTRY: a global initiative

The V-REGISTRY is an international project linked to the v-WIN (Venous-lymphatic World International Network) foundation. It is presented in congress programmes and interviews as a global real-world registry focusing on venous and lymphatic conditions, with participation from multiple continents.

In various scientific meetings and newsletters, V-REGISTRY is highlighted as:

  1. a way to collect real-world evidence beyond single-centre experiences;
  2. a platform to share data and expertise internationally;
  3. a tool to support discussions about education, quality of care and future policies in phlebology.

From a non-specialist perspective, the main idea is straightforward:

“Many teams worldwide contribute anonymised data so that venous and lymphatic diseases can be studied on a larger scale.”

The technical details (data structure, inclusion criteria, statistical methods) remain the responsibility of the scientific committees and are not the focus of this page.



Where does artificial intelligence come in?

Once large amounts of data are collected, the natural next step is to explore advanced analytic methods, including artificial intelligence.

Several recent reviews and congress sessions have discussed how AI could:

  1. help detect subtle patterns in imaging or Doppler studies (for example, early venous reflux);
  2. improve risk prediction for certain events in patients with venous disease;
  3. support clinicians by offering decision-support tools, not by replacing their judgement.

At the same time, experts point out that AI must be:

  1. transparent (how does the algorithm reach its conclusions?);
  2. rigorously validated (does it work in different countries and patient populations?);
  3. used under medical responsibility, as an aid and not as an autonomous decision-maker.

From the point of view of patients and the general public, AI should therefore be seen as a behind-the-scenes tool that may help improve understanding and organisation of care, while human clinicians remain at the centre of decision-making.



Ethical and legal questions: data protection first

Whenever large medical registries and AI are mentioned in the same sentence, important ethical and legal questions arise. Professional organisations have stressed that phlebology must remain extremely careful about:

  1. confidentiality of patient data and data leak risks;
  2. respect for medical secrecy and intellectual property;
  3. compliance with data-protection regulations in each country;
  4. informed consent and transparent communication about how data are used.

In other words, the community wants to benefit from real-world data and AI without compromising patient privacy or trust.



What does this mean (and not mean) for patients?

For a patient reading about V-REGISTRY and AI in phlebology, a few key ideas may be helpful:

  1. Your doctor may be contributing anonymised data to large registries that aim to improve knowledge and care.
  2. These data are meant to reflect real life, not just highly selected clinical trials.
  3. AI can be used to analyse these data, but it does not replace the consultation or the clinical examination.

On the other hand, V-REGISTRY and AI:

  1. do not allow a website or an app to give you a personal diagnosis based on a few clicks;
  2. do not justify self-management of complex venous conditions without medical supervision;
  3. do not change the basic rule: if you have symptoms or concerns, you should talk directly to a healthcare professional.


What this page is – and what it is not

To summarise, this “V-REGISTRY and AI” page on phlebo-online.org:

  1. offers an accessible overview of a major international registry and its connection to artificial intelligence;
  2. outlines the opportunities (better data, more robust analyses, support for education and guidelines);
  3. reminds readers of the ethical and legal safeguards that must be respected.

It does not:

  1. provide technical details about how V-REGISTRY is coded or governed;
  2. give any recommendation about individual treatments or investigations;
  3. replace the information given by your doctor, national societies or the official V-REGISTRY/v-WIN communication channels.

If you are personally affected by venous or lymphatic problems, the most useful step remains the same:

Discuss your situation with a healthcare professional, ask questions, and use information about registries and AI as a background, not as a substitute for medical care.
