Now, we are attending to Annual Meeting of Stroke 2015 in Hiroshima, Japan. This is the biggest meeting on science and clinical practice in cerebral stroke in Japan. Our staffs and residents present their recent progress on surgical and endovascular treatments for cerebrovascular diseases, including cerebral aneurysm, carotid stenosis, dural arteriovenous fistula, moyamoya disease, and so on. We hope that our residents would be excellent neurosurgeons through clinical and academic training at our department and affiliate hospitals.
