About Neuroendovascular Therapy

At the Department of Neuroendovascular Therapy, we perform cerebrospinal angiography and treat various vascular diseases in a minimal invasive fashion using a small tube called a catheter through the blood vessels In general, we close abnormal blood vessels for diseases that cause bleeding, and open narrow or occluded blood vessels for diseases that cause cerebral infarction. We also treat vascular anomalies of the head and neck, either by closing the abnormal vessels through the blood vessels, or by injecting a sclerosing agent into the lesion by directly puncturing it with a needle. Dr. Niimi, the department head, is capable of treating various vascular diseases, such as pediatric cerebrovascular diseases, spinal cord vascular diseases, vascular malformation of the head and neck, etc. based on his years of clinical experience in the United States.

We treat following diseases at our department by minimally invasiveendovascular technique.


Hemorrhagic diseases

  1. Cerebral Aneurysm
  2. Anteriovenous Malformation (AVM)
  3. Dural Arteriovenous Fistula
  4. Brain Tumors such as Meningioma

Occlusive diseases

  1. Carotid Artery Stenosis
  2. Subclavian Artery Stenosis
  3. Intracranial Artery Stenosis
  4. Acute-stage Cerebral Infarction

Spinal Cord and spine vascular diseases

Head and Neck/Facial Vascular Malformation, hemangioma

Pediatric vascular diseases


Chemoembolization for head and neck malignancy or vascular lesion, temporaryballoon occlusion test of the carotid artery, etc.
