Dr. Sung Ho Lee has visited our department from Department of Neurosurgery, Kyung Hee University Hospital, Seoul, Korea. He is very interested in cerebrovascular and endovascular surgery, and is also keen to learn our education system for medical students and residents. Although his stay in Toyama is rather short, We hope that he would be able to learn here as many as possible and also to enjoy a lot of great nature, seafoods, and sake in Toyama.
