Neurosurgery

(1) Overview

The Department of Neurosurgery collaborates with the Gamma Knife Center and the Department of Neurology to provide care for neurological disorders. Our specialties range from emergency neurological conditions requiring rapid and accurate treatment—such as stroke and epileptic seizures—to brain tumors that demand advanced therapeutic techniques.
We perform surgical treatments* for a variety of conditions, including subarachnoid hemorrhage, cerebral aneurysms, arteriovenous malformations (AVMs), cerebral hemorrhage, skull base tumors and benign brain tumors such as acoustic neuromas and meningiomas, malignant tumors such as gliomas and metastatic brain tumors, as well as trigeminal neuralgia, hemifacial spasms, spinal cord tumors, spinal arteriovenous malformations, and moyamoya disease.

*Number of surgeries performed: 453 (from January to December 2024)

(2) Policy

We Value Patients-Centred Specialist Care

We strive to achieve better outcomes in the long term for our patients by providing safe, patient – centred approach. For example, our surgeries are performed by experienced surgeons while using electrophysiological monitoring and navigation system to monitor cerebral function under anesthesia in order to improve safety and accuracy of our surgeries.

(3) Our Strengths

Striving for Highly Accurate and Safe Surgeries

In brain surgery, it is important to minimize any damage to the healthy brain in order to optimize the postoperative function for the patients. We perform surgeries while identifying healthy brain tissues under a microscope, preserving as much healthy brain tissue as possible.

Our surgeons routinely practice surgeries using microscopes in order to perform highly accurate surgeries. Our surgeons undergo daily trainings to suture under microscopes using thread finer than human hair.

We Value Teamwork and Actively Collaborate With Other Team Members

For treatment of brain diseases, it is important to consider not only the diseases themselves, but also the social backgrounds such as the patient’s general condition and the social backgrounds such as home environment. We organize daily conference meetings in order to actively share information with other departments such as Neurology, Cerebrovascular Medicine, Rehabilitation, co-medical staff, and the social workers.

We Respond to Emergency Stroke Patients 24/7

We operate a stroke hotline system twenty four hours a day, seven days a week. We accept referals directly from neigbouring medical institutions and rescue teams in suspected cases of stroke, allowing smooth and quick treatments for the patients. We often perform emergency surgeries when those stroke cases are accepted by our stroke hotline.

Message for Our Patients

Our neurosurgery department often performs craniotomy (open surgery) under general anesthesia using microscopic techniques for conditions such as brain tumors and cerebral aneurysms.

The hospital is staffed with surgeons who have extensive surgical experience and is actively focused on accumulating know-how. For example, Dr. Inoue, the Chief of Neurosurgery, has performed the following number of lifetime surgeries (from May 1997 to January 2025): 1,200 craniotomies for cerebral aneurysm clipping, 600 craniocerebral vascular bypass surgeries, 570 carotid endarterectomies, 600 craniotomies for brain tumor removal, 600 craniotomies for intracerebral hematoma evacuation, and 140 microvascular decompression surgeries via craniotomy.

We receive an increasing number of referrals for more technical and delicate surgeries such as large brain aneurysm and brain tumors (including skull base brain tumor surgeries and acoustic neuroma surgeries), cerebral vascular anastomosis and cerebrovascular moyamoya disease.
We look forward to welcoming you to our department and please do not hesitate to consult us if you have any questions.
