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 syndrome has rarely been reported in association with Down syndrome. We report a case of an 11-year-old female child with Down syndrome who presented with hemiparesis and facial palsy. Imaging investigations (magnetic resonance angiography and digital subtraction angiography) revealed the classical Moyamoya pattern. Work-up for prothrombotic and autoimmune disorders was negative. The n...
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...
Neurofibromatosis type 1 is a multisystem genetic disease of autosomal dominant transmission that reveals important cutaneous manifestations such as café-au-lait spots, multiple neurofibromas, and ephelides in skin fold areas, as well as hamartomatous lesions in the eyes, bones, glands, and central nervous system. Moyamoya disease is a rare progressive vaso-occlusive disorder that occurs with i...
OBJECTIVE To describe a rare case of moyamoya syndrome associated with systemic lupus erythematosus (SLE). PRESENTATION AND INTERVENTION A 22-year-old woman presented with left-sided hemiparesis in addition to fever, fatigue and malar rash. Brain magnetic resonance imaging revealed acute infarction in the right middle cerebral artery territory. Cerebral angiography showed features of moyamoya...
