In the pioneering development of interventional medicine in China, Zhang Jinshan has been an indispensable founder and leading figure. As China’s first overseas-trained doctoral graduate in radiological medicine, he returned to China in the 1980s after completing his studies abroad and introduced cutting-edge international interventional technologies to the country. Over more than four decades of dedicated practice and research, he has helped propel Chinese interventional medicine from its infancy to a position at the forefront of the global field through his exceptional clinical expertise and profound academic accomplishments.

Professor Zhang Jinshan has long been dedicated to the field of medical imaging and has developed distinctive expertise in selective and superselective interventional diagnosis and treatment for solid tumors such as liver cancer, demonstrating exceptional technical proficiency and profound academic accomplishment. Beginning in the 1990s, he led his team in pioneering the clinical application and research of TIPSS and B-ORTO in China, filling major gaps in the domestic field and opening new paths for the interventional management of gastrointestinal bleeding caused by portal hypertension secondary to liver cirrhosis. In addition, he has made groundbreaking contributions to the interventional diagnosis and treatment of peripheral vascular diseases, as well as to preoperative embolization for spinal tumors.

In the field of liver cancer treatment, Professor Zhang Jinshan not only led the development of standardized treatment protocols for liver cancer but also pioneered Transcatheter Arterial Chemoembolization with temporary Hepatic Vein Thrombosis (TACE-THVO) for primary liver cancer, bringing the efficacy of interventional therapy to a new level. In recognition of his outstanding clinical and scientific contributions, he was awarded the honorary title of “Chinese Master of Interventional Radiology” at the 2019 annual conference of the Chinese College of Interventionalists.

Professor Zhang Jinshan is not only a master clinician but also a driving force in the development of the discipline and a dedicated mentor in talent cultivation. He led his team in establishing one of China’s premier interventional therapy centers. As a doctoral supervisor, he has trained a large number of outstanding specialists and future leaders in interventional medicine, with many of his students and protégés now serving across the country. Academically, he has led multiple key national and military research projects, published more than 300 academic papers, and served as chief editor of three monographs, making remarkable contributions to the establishment of China’s academic framework for interventional medicine and the nationwide dissemination of its technologies.

From the laboratory to the operating room, and from academic podiums to grassroots hospitals, Professor Zhang Jinshan has consistently upheld the principles of “pioneering, innovation, pragmatism, and compassion". He has devoted his life to fulfilling the mission of a physician—relieving patients’ suffering through minimally invasive techniques and advancing the discipline through academic excellence—thereby establishing himself as a truly towering figure and one of the foremost authorities in the field of interventional medicine in China.
Professor Zhang Jinshan has achieved prolific academic accomplishments, having published over 300 academic papers covering areas such as interventional therapy for liver cancer, minimally invasive treatment of portal hypertension, interventional treatment of vascular diseases, and tumor ablation.
