Introduction
Advancing the Future of Aortic Care Through International Collaboration
Since its establishment in 2003, the Kawasaki Aortic Center (KAC) has continuously promoted active international collaboration through the acceptance of overseas fellows and observers, active participation in international scientific meetings, and surgical mentorship at medical institutions abroad.
As of February 2026, a total of three physicians from Thailand and Taiwan are training at our center as clinical fellows, striving to acquire advanced surgical techniques and perioperative management skills. In addition to long-term fellows, KAC regularly welcomes short-term visitors and training groups from overseas. These programs involve not only physicians but also multidisciplinary professionals, including nurses and clinical engineers. Through surgical observation and the sharing of perioperative management expertise, we contribute to international professional exchange and the advancement of global medical standards.
In 2018, KAC signed a Memorandum of Understanding (MOU) with the Society of Thoracic Surgeons of Thailand (STST), which was renewed for the first time in Bangkok in 2025. Furthermore, in February 2026, KAC established a new MOU with the Taiwan Society for Vascular Surgery (TSVS), steadily expanding its international collaborative network.
In 2025, as part of a collaborative initiative with STST, KAC launched the Visiting Professor Program, through which Dr Ozaki the Associate Director of our center stayed in Thailand for one year to provide surgical training and educational activities. This program represents a symbolic initiative promoting international technical exchange and the development of future generations of surgeons.
Since 2022, KAC has also hosted the weekly online case conference, the Kawasaki Aortic Surgery (KAS) Conference, held every Monday. Physicians from around the world—including Taiwan, Thailand, India, France, and Ukraine—participate regularly, fostering continuous international academic exchange through case discussions and knowledge sharing.
To date, numerous healthcare professionals from countries including Thailand, Taiwan, the Philippines, Vietnam, India, France, Ukraine, and Ethiopia have visited KAC for clinical training and academic exchange.
The Kawasaki Aortic Center will continue to actively promote international collaboration and educational initiatives, contributing not only to the advancement of aortic care in Japan but also throughout Asia and the global medical community.

I personally consider open aortic surgery as the standard treatment for aortic disease, but it is one of the difficult cardiovascular surgeries which needs much experience for operating team. To perform aortic operation by myself, I must learn from expert surgeons in one of the well-established aortic centers.
I have known about KAC since the past 6 years when Dr. Oshima gave a presentation in Thai Cardiovascular and thoracic surgery annual meeting and made the Memorandum of Understanding (MOU) with the Society of Thoracic Surgeons of Thailand (STST) in 2017.
After I graduated Cardiovascular and thoracic training in 2018, I decided for training in KAC, and eventually started working in July 2023 to until December 2023.
KAC has many open aortic cases with a variety of diseased stages and conditions which provide me with lots of experience in aortic surgery. There are many sessions for operative planning, discussion, and decision for every patient. One of the beneficial conferences is KAS conference, a weekly online international conference, which provides surgical expertise sharing from different experienced center and, also, continuity of learning for difficult and uncommon aortic surgery after graduation.
During my training, I experienced about 150 open aortic surgeries in 6 months, and, among these cases, I had several chances to be one of assistants, a total number is approximately 100 operations.
I am very grateful to become one of the trainees in Kawasaki Aortic Center.

When the number of cases increase and a good infrastructure is given to competent staff, the surgical outcomes will no doubt be superb. These are what KAC have, competent staff doing their share in the Aortic team the best they can. Its coupled by a good infrastructure and a caseload second to none.
KAC is a highly specialized center with very competent staff working together with a purpose, to deliver the best Aortic care possible. Emphasis is not only on the technical side of Aortic Surgery but also the patient preparation and post operative care. Our Aortic Database is one of the most robust that I know off. The Center has a long track record of doing complicated Aortic procedures in a high level. From its humble beginnings in the early part of the millennium, it blossomed as one of the best Aortic Centers there is.
I came here because I want to learn Aortic Surgery, the KAC style. My teachers and seniors here are very friendly and willing to share their expertise with me all the time. They helped me adjust to my life away from home. Teachers may go as far as having illustrations and schema written when we discuss to make sure the young surgeons understand the teacher’s topic. For all these, I am very thankful.
