Neurosurgery

The Department of Neurosurgery specializes in surgical treatment for tumors of the brain and spinal cord, cerebro-vascular disorders (aneurysm, vascular malformation, etc.), and functional brain disorders (epilepsy, Parkinson’s disease, pain, etc.).

Medical services

Consultations for new patients are provided daily. Specialized outpatient services are provided on Mondays, Wednesdays and Fridays. Surgery is performed on Tuesdays, Wednesdays and Thursdays. Inpatients are under the care of 15 staff physicians and 8 residents who are divided into four teams. The department employs 15 neurosurgeons certified by the Japan Neurosurgical Society, two specialists certified by the Japan Stroke Society, one specialist certified by the Japan Epilepsy Society, and one specialist certified by the Japanese Society for Neuroendovascular Therapy.

Diagnosis and treatment policy

With state-of-the-art devices for diagnosis and treatment and abundant human resources that are available from the university, optimal treatment can be provided for individual patients. Surgery is carefully simulated and perioperative monitoring and navigation are used for treatment.

Specialties

  • Surgical and postsurgical treatment for various brain tumors (particularly malignant brain tumor, skull base tumor, meningioma, acoustic tumor, pituitary tumor)
  • Surgery for cerebrovascular disorders (cerebral aneurysm, giant/thrombosed cerebral aneurysm, cerebral arteriovenous malformation, cavernous malformation, moyamoya disease, carotid stenosis)
  • Neuroendovascular surgery (cerebral aneurysm, carotid stenosis, dural arteriovenous fistula, cerebral arteriovenous malformation)
  • Surgical treatment for epilepsy
  • Surgery for trigeminal neuralgia and hemifacial spasm
  • Surgical treatment for Parkinson’s disease
  • Gamma knife radiosurgery for benign and metastatic brain tumor
  • Gamma knife radiosurgery for cerebral arteriovenous malformation

Target diseases

Brain tumors such as meningioma, glioma, metastatic brain tumor, acoustic tumor, and pituitary adenoma; vascular disorders such as cerebral aneurysm and cerebral arteriovenous malformation; functional disorders such as hemifacial spasm, trigeminal neuralgia, refractory epilepsy, and Parkinson’s disease; other disorders such as hydrocephalus and congenital abnormality.

Advanced treatments / Specialized tests

  • Gamma knife
  • Vagus nerve stimulation therapy for epilepsy

Frequently performed tests

  • CT, MRI: brain imaging examination
  • Functional MRI, magnetoencephalography (MEG): brain function test
  • Electroencephalography (EEG): epileptic focus examination
  • SPECT, PET: cerebral blood flow and cerebral metabolism test
