International Union of Phlebology

What International Union of Phlebology does

The International Union of Phlebology (UIP), also known as the World Union of International Phlebolymphology (WUIP), is a non-profit international professional medical society founded on March 24, 1959, and headquartered in Chatswood, NSW, Australia. It is the longest-standing global umbrella organization for phlebology, federating 90+ national and regional scientific societies across all continents and serving the professionals who treat venous and lymphatic disorders — vascular surgeons, phlebologists, interventional radiologists, dermatologists, nurses, and sonographers. UIP's core deliverables are biennial World Congresses (UIP2023 Miami, UIP2025 Buenos Aires, UIP2027 Tbilisi) drawing 1,200–2,100+ delegates from 60+ countries, an online phlebology education module library, consensus and clinical guideline documents published in peer-reviewed journals, research grants and prizes, the monthly UIProject Month 24 Zoom series, the Engagement Working Group for young professionals, and a tiered membership and outreach program.

The organization is governed by an Executive Committee led by President Sergio Gianesini (2023–2027), Executive Director David Connor, and Treasurer Paul Thibault, with regional Vice Presidents covering Northern Europe, Southern Europe, South/Central America, and other geographies. Revenue mechanics consist of recurring tiered annual membership dues from national societies (Tier 1, 2, 3), transaction-based income from biennial World Congress registrations and sponsorships (UIP2023 Miami was co-hosted with AVLS, AVF, and Mexican societies), discounted online access to the official International Angiology journal (€45/member for Tier 1 societies, free for Tier 2/3 and residents), and ancillary research grant and prize disbursements. Distribution runs through 90+ member societies acting as resellers, direct event registration, and self-serve access to online education. UIP is currently undergoing a Constitutional Reform after legal review found its existing constitution to be of no legal standing, and has expanded its digital engagement infrastructure with a redesigned website (2021) and the UIProject Month 24 monthly program.

Broad incumbents

• International Society on Thrombosis and Haemostasis (ISTH): Global scientific society addressing thrombosis and haemostasis with overlapping membership (vascular specialists treating VTE); broader in scope but collaborates with phlebology bodies on guidelines and surveys in adjacent disease areas.
• Society for Vascular Surgery (SVS): Larger U.S. vascular surgery society whose journal (Journal of Vascular Surgery) publishes UIP consensus statements; addresses the same vascular surgeon audience but as a broad incumbent covering arterial, venous, and lymphatic care.

Direct peers

• Australasian College of Phlebology: Australia/New Zealand phlebology college hosted UIP2018 Melbourne and shares many overlapping leaders (Paul Thibault serves as Treasurer of both bodies); offers comparable membership, training accreditation, and congress activities for the same specialty audience.
• European Venous Forum: European-focused phlebology society that is itself a member of the UIP network; collaborates on guidelines and educational initiatives targeting the same vascular specialists, dermatologists, and interventional radiologists across Europe.
• American Vein and Lymphatic Society (AVLS): U.S.-based medical society for phlebology and lymphatic medicine; co-hosted UIP2023 Miami and serves as the largest national counterpart to UIP, with overlapping member profiles (vascular surgeons, phlebologists, sonographers) and similar educational programming including annual congresses and online CME.
• International Compression Club (ICC): UIP partner organization focused on compression therapy; collaborates on consensus documents and congress sessions, serving an overlapping clinician audience with shared interest in venous disease management.
• Venous Association of India: India-based phlebology society whose founding president (Malay Patel) serves as Assistant General Secretary of UIP; directly comparable as a national member society delivering vein-care education and congresses to vascular specialists.
• Canadian Society of Phlebology: U.S. member society of the UIP; represents Canadian phlebologists and shares overlapping leadership (e.g., Douglas Hill as Past President); delivers similar CME and clinical guidelines content to the same specialty audience.

Emerging players

• Venous-Lymphatic World International Network (v-WIN): Founding member of UIP founded by current UIP President Sergio Gianesini; operates as an agile, digital-first complementary organization driving projects like UN recognition and World Expo presence, serving the same vein-lymphatic clinician community.
• American College of Phlebology Foundation: U.S. foundation focused on phlebology research and education; overlaps with UIP's consensus/guidelines work and shares clinician members, but emphasizes research funding over international federation governance.
