A Greeting from the Professor

The Department of Neurosurgery at Akita University offers the most up-to-date evaluation and treatments for all neurosurgical disorders, including cerebrovascular diseases, brain tumors, spine and spinal cord diseases, and other related neurosurgical problems.

Our department is divided into the groups of cerebrovascular surgery, brain tumor surgery, spine surgery, stereotactic radiosurgery and functional neurosurgery. Neurosurgical operating rooms are equipped for image-guided stereotaxis, neuro-endoscopy, brain mapping, neurophysiological brain monitoring and intraoperative digital subtraction angiography. These facilities, as well as a stereotactic radiosurgery system, help us provide safe and successful treatment of some of the most complex intracranial aneurysms, arteriovenous malformations, brain tumors, cerebral ischemic diseases and spine diseases.

Our training programs are designed to promote understanding of neurosurgery (including microneurosurgical techniques and skills) and to inspire a multidisciplinary approach to achieve the best clinical results and a scientific spirit of inquiry. Our research programs have also recently expanded, particularly in the areas of ischemic brain injury, vasospasm, brain tumor biology and functional brain mapping. Our goal is to provide excellent care to patients with neurosurgical disorders, and this is accomplished through the advancement of scientific knowledge and technical expertise.
