Dr. Yasuaki Arai received his medical degree at Jikei University School of Medicine and his doctorate in medical science at Nagoya City University Graduate School of Medicine. After 5 years of training at Tokyo Medical Center, he worked in the Department of Diagnostic and Interventional Radiology at Aichi Cancer Center. After 7 years as Department Chair, he moved to the National Cancer Center as Department Chair of Diagnostic Radiology. He also served as the Director of the National Cancer Center Hospital from 2012-2016, and as the President of the Japanese Society of Interventional Radiology (JSIR) from 2014-2017.
Dr. Arai has developed several new devices such as an implantable port system, an angio-CT system, a tip-deflecting microcatheter, as well as new techniques such as percutaneous catheter placement via the left subclavian artery with a side-holed catheter fixed to the gastroduodenal artery for hepatic arterial infusion chemotherapy (HAIC), trans-jugular trans-hepatic peritoneo-venous shunt catheter placement for intractable ascites, the creation of an extra-anatomical bypass for occluded canal organs, and new regimens of HAIC such as a high weekly dose of 5FU and FEM (5FU, Epirubicin and Mitomicin-C). Dr. Arai is also the originator of the Japanese Interventional Radiology in Oncology Study Group (JIVROSG) which conducts over 30 clinical studies in the field of interventional oncology.
Dr. Arai has published more than 200 scientific papers in major journals and has been an associate editor of several leading international journals, including the Journal of Vascular & Interventional Radiology (JVIR) and Cardiovascular and Interventional Radiology (CVIR). He has served as a consultant on medical devices for various Japanese government agencies. Dr. Arai has given lectures related to interventional radiology and clinical trials worldwide and has greatly contributed to building bridges between countries. His lectures about the mechanism of conventional TACE, the importance of evidence, and the required determination to overcome tough cases have greatly influenced young interventional radiologists all over the world.
Dr. Arai has received many awards at international IR congresses such as GEST in 2010 (Annual Lecture), ECIO in 2015 (Honorary Lecture), TSR in 2015 (International Honorary Member), CIRSE in 2017 (Distinguished Fellow), CCI in 2018 (International Honorary Member), APSCVIR in 2021 (Gold Medal), etc.
Since his retirement from the National Cancer Center in 2018, Dr. Arai has continued to work as a guest researcher for the National Cancer Center, a guest professor at Tokyo Jikei University School of Medicine and Saitama Medical University, a clinical professor of St. Marianna University of Medicine and as a chief doctor at Uonuma City Koide Hospital.
Dr. Arai is father to a son and two daughters. In his free time, he enjoys mountain climbing and is particularly fond of the Himalayan mountains. He plays the base, the keyboard and sings in a Beatles tribute and blues rock band.
Dr. Arai has been fully enjoying his life, not only in the field of interventional radiology, but also spreading happiness.
