Neurosurgery department in Kameda Medical Center accepts all emergency diseases in the area of neurosurgery as a core hospital in the southern part of the Boso Peninsula with the cooperation of the emergency department, neurology department, radiology department and surgery department. We have a system in place that allows us to perform CT scan, MRI, and cerebrovascular examinations at any time. With the restraint system of a trained neurosurgeon, advanced neurosurgical operations such as cerebral aneurysm clipping are available 24 hours a day, 365 days a year. It is possible. Since we also support transportation by helicopter, we also accept the patients from the northern part of the Boso Peninsula and the entire Kanto region.
