The impact of chronic cerebral hypoperfusion on resting-state blood oxygen level-dependent signal fluctuations remains unknown. We aimed to determine whether chronic ischemia induces changes in amplitude of low-frequency fluctuations (ALFF) and to investigate the correlation between ALFF and perfusion-weighted magnetic resonance imaging (PWI) parameters in patients with moyamoya disease (MMD). Thirty patients with pre- and postoperative resting-state functional magnetic resonance imaging and PWI were included, and thirty normal controls underwent resting-state functional magnetic resonance imaging...

Febrile infection-related epilepsy syndrome (FIRES) is a form of epileptic encephalopathy with severe refractory epilepsy that presents in previously healthy, school-aged children after significant febrile illness with concomitant rise in body temperature. Suspected causes include genetic or acquired channelopathies, as well as mitochondrial disturbances. In FIRES, the EEG shows diffuse slowing, generalized, and/or multifocal discharges. Seizures are present and resistant to treatment. Moyamoya angiopathy (MMA) is characterized by progressive stenosis of cerebral arteries and subsequent development of a network of collateral circulation that is prone to rupture...

Moyamoya syndrome is a progressive cerebrovascular disease that is characterized by stenosis of the terminal portion of the internal carotid artery and its main branches, in combination with an accompanying disease. We herein describe an 8-year-old boy exhibiting transient loss of consciousness, who had recurrent seizures in infancy with progressive brain calcification. On admission, he was alert but magnetic resonance angiography showed bilateral stenosis of the whole internal carotid artery and proliferation of vascular collaterals, and brain CT revealed calcification on bilateral putamen...

Moyamoya syndrome (MMS) is the most common cerebral vasculopathy among children with neurofibromatosis type 1 (NF1). In this study, we clinically, radiologically, and genetically examined a cohort that was not previously described, comprising European children with NF1 and MMS. The NF1 genotyping had been registered. This study included 18 children. The mean age was 2.93 ± 3.03 years at the NF1 diagnosis and 7.43 ± 4.27 years at the MMS diagnosis. In seven patients, MMS was diagnosed before or at the same time as NF1...

BACKGROUND: The genetic architecture of coronary artery disease has not been fully elucidated, especially in Asian countries. Moyamoya disease is a progressive cerebrovascular disease that is reported to be complicated by coronary artery disease. Because most Japanese patients with moyamoya disease carry the p.R4810K variant of the ring finger 213 gene (RNF213), this may also be a risk factor for coronary artery disease; however, this possibility has never been tested. METHODS AND RESULTS: We genotyped the RNF213 p...

This study proposes a method for territorial segmentation and volumetric flow rate (VFR) distribution measurement of cerebral territories based on time-resolved contrast enhanced magnetic-resonance-angiography (MRA). The method uses an iterative region-growing algorithm based on bolus-arrival-time with increased temporal resolution. Eight territories were segmented: (1) right and (2) left internal carotid arteries, including the middle cerebral artery (ICA+MCA), excluding the anterior cerebral arteries (ACA); (3) right and left ACA (R+L-ACA); (4) right and (5) left external carotid arteries (ECA); (6) right and (7) left posterior cerebral arteries (PCA); and (8) vertebrobasilar territory...

The main change of moyamoya disease (MMD) is steno-occlusion at the terminal portion of the bilateral internal carotid arteries (ICAs). Occlusion of distal portions of the bilateral vertebral arteries (VAs) in MMD has never been reported. An 18-year old female was admitted with repeated headache for 13years. Cerebral digital subtraction angiography (DSA) demonstrated occlusion of bilateral ICAs at their terminal portions, moyamoya vessels at the skull base, occlusion of bilateral distal VAs and the basilar artery (BA) fed by the tortuous collateral vessels arising from the cervical segment of VAs...

PURPOSE: Reduced flow in the internal carotid artery (ICA) is related to cerebral ischemia. We established a classification of reduced ICA flow through color-coded carotid duplex (CCD) sonography. METHODS: We retrospectively reviewed 25,000 CCD images in sonography laboratory. RESULTS: Reduced ICA flow [flow volume (FV) less than 100 mL/min] was found in 1.2% of all studies, and 270 patients were enrolled. We included 8% patients with lesions proximal to the ICA in Group A, 27% with lesions at the proximal ICA in Group B, 49% with lesions distal to the visible ICA in Group C, and 16% with unknown causes in Group D...

Moyamoya disease is a chronic cerebrovascular occlusive disease that is characterized by progressive stenosis of the terminal portion of the internal carotid artery and its main branches. The occurrence of Moyamoya disease is related to immune, genetic, and other factors. Though the research of Moyamoya disease has made great strides in the past 60 years, the etiology and pathogenesis are largely unknown. This review will focus on the genetic pathogenic and inflammation factors of Moyamoya disease.

Occurrence of moyamoya syndrome in a patient with Smith-Magenis syndrome (SMS) has previously been reported once in a 10-year-old Asian female. We report a second case of moyamoya in a patient with SMS, in a now 25-year-old Asian female diagnosed with both conditions as a child. In addition to describing her medical and surgical history, we provide a detailed report of her omental transposition, in which the omental circulation was anastomosed to the superior thyroid artery and external jugular vein. To our knowledge, this is the first report of omental transposition for moyamoya in which omental vessels are anastomosed to vessels in the neck, as well as the second report of moyamoya in a patient with SMS...

OBJECTIVE: While a significant amount of experience has accumulated for awake procedures for brain tumor, epilepsy and carotid surgery, its utility for intracranial neurovascular indications remains largely undefined. Awake surgery, for select neurovascular cases, offers the advantage of precise brain mapping and robust neurological monitoring during surgery for lesions in eloquent areas, avoidance of potential hemodynamic instability, and possible faster recovery. Additionally, it opens the window for perilesional epileptogenic tissue resection with potentially less risk for iatrogenic injury...

Superficial temporal artery-middle cerebral artery (STA-MCA) anastomosis is the standard surgical treatment for moyamoya disease (MMD). The main potential complications of this treatment are cerebral hyperperfusion (CHP) syndrome and ischemia, and their managements are contradictory to each other. We retrospectively investigated the incidence of the simultaneous manifestation of CHP and infarction after surgery for MMD. Of the 162 consecutive direct revascularization surgeries performed for MMD, we encountered two adult cases (1...

BACKGROUND: Moyamoya angiopathy (MMA) is characterised by a progressive stenosis of the terminal part of the internal carotid arteries and the development of abnormal collateral deep vessels. Its pathophysiology is unknown. MMA can be the sole manifestation of the disease (moyamoya disease) or be associated with various conditions (moyamoya syndrome) including some Mendelian diseases. We aimed to investigate the genetic basis of moyamoya using a whole exome sequencing (WES) approach conducted in sporadic cases without any overt symptom suggestive of a known Mendelian moyamoya syndrome...
