Professor Susumu Miyamoto's research lab specializes in cerebrovascular diseases, with a primary focus on moyamoya disease, intracranial hemorrhage, and cerebrovascular interventions. The lab investigates cerebrovascular hemodynamics, revascularization techniques such as extracranial-intracranial bypass, and the long-term outcomes of surgical and medical management in stroke patients. Their work is deeply rooted in clinical trials and evidence-based guidelines, including the Japan Adult Moyamoya Trial, which evaluates the efficacy of revascularization in preventing recurrent bleeding.

The revised Japan Stroke Society Guidelines for the Treatment of Stroke were published in Japanese in July 2021. In this article, the extracted recommendation statements are published. The revision keeps pace with the great progress in stroke control based on the recently enacted Basic Act on Stroke and Cardiovascular Disease in Japan. The guideline covers the following areas: primary prevention, general acute management of stroke, ischemic stroke and transient ischemic attack, intracerebral hem
Eighty-two cases of cerebrovascular moyamoya disease were studied by cerebral angiography and computerized tomography. Occlusive lesions were demonstrated not only in the anterior circulation but also in the posterior circulation, and they were associated with the development of an abnormal vascular network (moyamoya vessels). Although occlusive lesions do occur in the vertebrobasilar system, the vertebrobasilar system also acts as a source of collateral channels to the anterior circulation in t
Palliative treatments cannot prevent bleeding and may even worsen the posttreatment course compared with the natural history of cerebral AVMs. A more conservative indication is required in recommending palliative treatment alone.
The involvement of the posterior circulation in moyamoya disease was studied in 178 patients. Forty-three had several types of disturbance such as visual field defect, decreased visual acuity, episodes of blindness, and scintillating scotomata. Most of these symptoms were attributed to occlusive lesions in the posterior circulation. Visual disturbances were seen more often in patients with a juvenile onset than in cases of adult onset. Superficial temporal artery (STA) to middle cerebral artery
This article summarizes the study design and organization of a multicenter, prospective randomized trial of extracranial-intracranial (EC-IC) bypass for treating adult patients with moyamoya disease who suffered episodes of intracranial bleeding. The Japan Adult Moyamoya Trial will determine whether the combination of EC-IC bypass with risk factor modifications affects the prognosis and the incidence of recurrent bleeding attacks. Direct bypass such as superficial temporal artery-middle cerebral
