The 16^th International Symposium on Sympathetic Surgery – ISSS 2025, which will be held at Recife Expo Center – Pernambuco – Brazil, from May 6th to 7th, 2025, presents a great challenge to organize after a few years of pandemic, when we were forced to doing it virtually, but at this moment living in another reality is ideal for us to reconnect with the professionals who work with these techniques here in Brazil and on all continents in the world. With the invaluable support of the Board of Directors of the Brazilian Society of Thoracic Surgery and the Local Organizing Committee, we will dedicate all effort to the organization and attention to detail to exceed all expectations.

Here, at this moment, we hope to bring together more than 200 national and international congressmen, for an event that will stand out for a scientific program of the highest quality, which will address the most important themes in the specialty, as well as professionals from different specialties to present together what is the most current and relevant for the International Society on Sympathetic Surgery. Just as a reminder, the last time we had the opportunity to host this event was in 2007, also in Recife, and to this day we are proud to say that we reached a record number of participants close to 330 full members in the auditorium.

Counting on your participation in this event, we hope to share with you all the success of the 16^th International Symposium on Sympathetic Surgery – ISSS 2025

Yours sincerely,

Organizing committee:

Dr. José Ribas M. Campos, MD – Chair

Dr. Alessandro Wasum Mariani, MD

Dr. Wolfgang W. Schmidt Aguiar, MD
