Introduction

The neurosurgery department at our hospital uses reliable technology and diagnostic capabilities to provide safe and state-of-the-art treatments to provide medical care that patients and their families can trust, and strives to satisfy them.

Characteristics of this department

Iseikai International General Hospital is certified as a Primary Stroke Center and performs mechanical thrombectomy in addition to rt-PA intravenous therapy.
The neurosurgery department performs 320 surgeries per year, and in addition to cerebrovascular surgery, it also treats benign and malignant brain tumors, trauma, hydrocephalus, facial spasms, trigeminal neuralgia, and more.

Reception

Main diseases

Brain tumors

• Gliomas
• Anaplastic gliomas
• Glioblastomas
• Meningiomas
• Neurilemomas
• Pituitary adenomas
• Metastatic brain tumors

Cerebral vascular disorders

Operative surgeries

We have doctors who are skilled in both craniotomy and intravascular catheter surgery, and we strive to provide minimally invasive treatments based on team medical care. Even in craniotomy, we strive to perform minimally invasive surgeries by using navigation and fluorescent evoked electromyography with ICG and 5ALA.

Craniotomy

• Cranial tumor removal (including extensive skull base surgery)
• Endoscopic pituitary tumor removal
• Cranial clipping
• Cranial hematoma removal
• Endoscopic hematoma removal
• Microvascular decompression for facial spasms and trigeminal neuralgia
• External decompression

Catheterization

• Coil embolization for cerebral aneurysms
• Stent placement for carotid artery stenosis and subclavian artery stenosis
• Percutaneous cerebral thrombectomy
• Percutaneous cerebral angioplasty for intracranial vascular stenosis
• Tumor embolization for brain tumors

Other

• Hydrocephalus surgery (VP shunt, LP shunt, endoscopic third ventricle floor fenestration)
• Chronic subdural hematoma burr hole irrigation
• Ventricular drainage

Outpatient schedule

Morning 9:00～12:00（Reception8:00-11:30）/
Afternoon to Evening 13:30～16:30（Reception13:00-16:00）
