Introduction: In Japan, the number of the severe head traumatic injury especially among young people has been decreasing because of toughening the road traffic law, decrease of the number of car owners among young people, and improvement of vehicle technologies for safety drive especially notable for evolution of automatic driving these days. It is of course favorable situation for us Japanese, but it has been worrisome problem for the neurosurgical trainee to experience the brain injury operations for the young patients. Miura peninsula, where our hospital is located in, is one of the most aging society in Japan. 61 traumatic brain injuries were operated in our hospital from 2016–2018, and average age is 67.9, and the number of the cases whose age was under 30 was only 3. The brain of the elderlies is atrophic and fragile and has low metabolic rate and hardens arteries, so the brain injury operations for the young patients is different from that for the elderlies.
Method: We have cooperated with the hospitals in Viet Nam since 2014, and some doctors in each country go and participate in medical practice especially in operation. In Viet Nam where there are some traffic problems such as so many owners of motor bicycle and too lenient traffic rules, there are much more traffic accidents than in Japan. Young neurosurgeons from our hospital experience the general operations like traumatic brain injury cases. On the other hand, the doctors from Viet Nam learn especially about microsurgical technique and monitoring system.
Result: Doctors from our hospital operated from 8–12 cases of traumatic brain injury cases during their stay. Every case was under 30 years old.
Conclusion: In Japan, as an aging society, it is getting to be difficult to experience the operations for traumatic brain injury in youth. In order to take over the experiences and techniques of traumatic brain injury operations, the international medical exchange could be one considerable option.
