As part of the on-going collaboration between TTS and our official Sections, and in order to provide TTS members with an update on areas of the field represented by TTS Sections, the following article has been submitted by the International Society of Vascularized Composite Allotransplantation.
The International Society for Vascularized Composite Allotransplantation (ISVCA) is the global society for vascularized composite allotransplantations (VCA). VCA represents all types of transplantations where a functional unit such as upper extremity or part of it such as hand is transplanted. These include face, larynx or neck organs, abdominal wall, urogenital, or lower extremity transplantation. In contrast to solid organ transplantation, these transplantations are often performed to enhance quality of life.
First transplantations that can be categorized as VCA were done already in the early and mid-1990’s. These included vascularized knee joints and antebrachial motor units for hand. The fear for immunogenicity of skin slowed the progression until the first modern era successful upper extremity transplantation was performed in 1998 by the team led by Max Dubernard in Lyon. There had been an attempt for hand transplantation already in 1964, but it failed soon due to rejection. The first laryngotracheal transplantation was performed in 1998 by Strome et al in Cleveland Philadelphia, the first abdominal wall transplantation in 2001 by Levi et al in Miami, Florida, tongue in 2003 by Ewer et al in Vienna, Austria, face in 2005 by Devauchelle et al in Lyon, penis in 2006 by Hu et al in Guangzhou, China, and lower extremity in 2006 by Zuker et al in Toronto, Canada.
During the past 20 years the number and types of VCA has steadily increased. However, since the field is still at the beginning of the journey in many of these procedures the numbers are still small. The amount of upper extremity transplantations to date is 160, for face 55, for abdominal wall 40, larynx 15, and for penis five transplantations. Most VCA’s have been performed in Europe or USA but most rapid increase in activity is in Asia. There are approximately 60 institutions in the world that have performed some type of VCA in 22 countries and in all five continents.
Since the field is small, scattered and evolving in many directions there is a true need for global network and community. ISVCA was born in 2002 for this purpose already in the early days of VCA.
Mission
Excellence in education, research, and advocacy of vascularized composite allotransplantation.
Objectives
To promote and encourage research and training relevant to the transplantation of vascularized peripheral tissues as a functional unit (a.k.a. composite tissue allotransplantation (CTA) or vascularized composite allografts (VCA)).
To provide a scientific forum for the exchange and discussion of clinical and experimental results and experiences relevant to transplantation of composite tissue allotransplantation or vascularized composite allotransplantation.
To promote and encourage contacts between clinical and experimental researchers from different institutions all pertinent disciplines irrespective of their country of origin.
To promote and facilitate support in the planning and execution of collaborative studies, and pursue collaboration with other associations, societies, and/or organizations serving similar purposes.
Council
ISVCA has a council of 8 councilors in addition to President-elect, President, Past President, Secretary-Treasurer, and an additional ninth councilor being responsible for global clinical data. Our past president was Dr. Hatem Amer from Mayo Rochester, USA, the current president is Dr. Patrik Lassus from Helsinki, Finland, and President-elect is Dr. Subramania Iyer from Amrita school of Medicine, India. The council is elected to represent all continents and different fields of VCA.
Meetings
ISVCA organizes a scientific congress in every two years. The previous meeting was in Helsinki in June 2025 and hosted 109 attendees. Before that, meetings were held in Los Angeles, USA, Cancun, Mexico, and New Delhi, India. The very first meeting for pioneers involved in the field was held already in 1993 in Louisville, USA
SAVE THE DATE - ISVCA 2027 - May 2-5 - Taipei, Taiwan
Webinars
ISVCA holds two TTS webinars per year. The previous webinar on face transplantation was October 20th 2025 and the next webinar will be Friday 19th December, 2025, 7 AM EST.
ISVCA works in close collaboration with the Chauvet work group. Many of the active participants in ISVCA and the field also participate in the Chauvet Workgroup. The Chauvet concept is to emphasize:
Importance of the psychological/psychiatric evaluation in VCA
Psychological impact of VCA
Creation of common protocols for evaluation, follow-up, and supportive treatment
The Chauvet workgroup addresses psychosocial domains and provides an interdisciplinary platform for the development of psychosocial guidelines and a multicenter research collaboration
All teams involved in VCA are invited to collaborate
The Chauvet Workgroup has organized three meetings of which the latest in 2025 was together with the ISVCA biennial meeting in Helsinki.
