Moyamoya disease is a rare neurovascular disorder that involves constriction of certain arteries in the brain. In patients with moyamoya disease, it is very important to prevent cerebral ischemic attacks and intracerebral bleeding caused by fluctuating blood pressure and increased respiration. A 40-year-old woman with moyamoya disease was scheduled for extraction of her right upper and lower im...

Moyamoya disease is a rare but well described entity which has been found in the angiographic investigation of subarachnoid hemorrhage, its most common symptom in adults. We present 4 patients in whom moyamoya disease and an intracranial saccular aneurysm were discovered. In 2 of the 3 patients suffering a hemorrhage, the aneurysm was the source of bleeding. Three of the aneurysms were located ...

The natural history of aneurysms of the major arteries after revascularization in moyamoya disease has yet to be documented. At our institute, we treated two patients with moyamoya disease-associated aneurysms involving major arteries of the posterior cerebral circulation. The aneurysms became enlarged at an early stage after revascularization, necessitating coil embolization. Although cerebral...

Moyamoya disease is a chronic, progressive bilateral occlusion or stenosis of terminal internal carotid arteries as well as the proximal anterior and middle cerebral arteries. Hemorrhage of the splenium of the corpus callosum rarely occurs with moyamoya disease. In this article, we report a case of a 53-year-old woman diagnosed with moyamoya disease by cerebral angiography. She presented to the...

Moyamoya disease is a unique cerebrovascular disorder characterized by idiopathic progressive stenosis at the terminal portion of the internal carotid artery (ICA) and fine vascular network. The aim of this review is to present the clinical application of quantitative digital subtraction angiography (QDSA) in pediatric moyamoya disease. Using conventional angiographic data and postprocessing so...

BACKGROUND AND PURPOSE Comprehensive multicenter data on treatment of pediatric moyamoya in the United States is lacking. We sought to identify national trends in the diagnosis and treatment of this disease. METHODS A total of 2454 moyamoya admissions from 1997 to 2012 were identified from the Kids Inpatient Database. Demographics, inpatient costs, interventions, and discharge status were ana...

Moyamoya disease is an occlusive intracranial arteriopathy owing to intimal hyperplasia with formation of abnormal cerebrovascular collateral networks; however, the etiology remains unclear. Although this disease is known to be associated with renovascular hypertension, it is extremely rare for it to be associated with stenoses of the coronary arteries. We herein described a case of a 56-year-o...

Moyamoya disease is a condition that results from bilateral stenosis or obstruction of the intracranial arteries at the base of the brain. Patients exhibit ischemic symptoms, and vascular reconstruction is the therapy of choice. Surgical treatment for Moyamoya disease is often complicated by cerebral ischemia, so the goal in perioperative management is to maintain the balance between oxygen sup...

Cerebrovascular disease (CBVD) is very common in the People's Republic of China (PRC). In 8 of 12 large cities in the PRC, CBVD ranked first in frequency as a cause of death. The ratio of aneurysms to arteriovenous malformations (AVMs) was 0.84-2:1, much lower than in the United States (6.5:1). Hypertensive intracerebral hemorrhage (HIH) is the commonest cause of mortality in patients with CBVD...
