Abstract
Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by progressive narrowing of the brain's arteries, leading to an increased risk of stroke. The primary susceptibility gene, RNF213, has been identified in individuals of East Asian descent, contributing to ongoing research into potential therapeutic targets. The distinction between idiopathic MMD and secondary forms, such as Moyamoya syndrome (MMS), is discussed, focusing on associated conditions and risk factors. Surgical revascularization emerges as the mainstay of treatment, with direct, indirect, and combination bypass procedures explored. The review delves into advancements in imaging technology for diagnosis and treatment planning, emphasizing non-invasive magnetic resonance examination's role in identifying asymptomatic patients. Additionally, insights into anesthetic care and therapeutic approaches underscore the evolving understanding of this complex disease. The presented information aims to contribute to the ongoing dialogue surrounding MMD, providing a valuable resource for clinicians and researchers.

Abstract
Monogenic cerebral vasculopathy is a rare but progressively recognizable cause of pediatric cerebral vasculopathy manifesting as early as fetal life. These monogenic cerebral vasculopathies can be silent or manifest variably as fetal or neonatal distress, neurologic deficit, developmental delay, cerebral palsy, seizures, or stroke. The radiologic findings can be nonspecific, but the presence of disease-specific cerebral and extracerebral imaging features can point to a diagnosis and guide genetic testing, allowing targeted treatment. The authors review the existing literature describing the frequently encountered and rare monogenic cerebral vascular disorders affecting young patients and describe the relevant pathogenesis, with an attempt to categorize them based on the defective step in vascular homeostasis and/or signaling pathways and characteristic cerebrovascular imaging findings. The authors also highlight the role of imaging and a dedicated imaging protocol in identification of distinct cerebral and extracerebral findings crucial in the diagnostic algorithm and selection of genetic testing. Early and precise recognition of these entities allows timely intervention, preventing or delaying complications and thereby improving quality of life. It is also imperative to identify the specific pathogenic variant and pattern of inheritance for satisfactory genetic counseling and care of at-risk family members. Last, the authors present an image-based approach to these young-onset monogenic cerebral vasculopathies that is guided by the size and predominant radiologic characteristics of the affected vessel with reasonable overlap. ©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

Abstract
OBJECTIVES Surgical revascularization for moyamoya arteriopathy decreases long-term stroke risk but carries a risk of perioperative ischemic complications. We aimed to evaluate modifiable stroke risk factors in children undergoing surgical revascularization for moyamoya. MATERIALS AND METHODS In this exploratory, single-center, retrospective cohort study, medical records of pediatric patients undergoing surgical revascularization for moyamoya arteriopathy at our center between 2003 and 2021 were reviewed. Candidate modifiable risk factors were analyzed for association with perioperative stroke, defined as ischemic stroke ≤7 days after surgery. RESULTS We analyzed 53 surgeries, consisting of 39 individual patients undergoing indirect surgical revascularization of 74 hemispheres. Perioperative ischemic stroke occurred following five surgeries (9.4%). There were no instances of hemorrhagic stroke. Larger pre-to-postoperative decreases in hemoglobin (OR 3.90, p=0.017), hematocrit (OR 1.69, p=0.012) and blood urea nitrogen (OR 1.83, p=0.010) were associated with increased risk of perioperative ischemic stroke. Weight-adjusted intraoperative blood loss was not associated with risk of perioperative ischemic stroke (OR 0.94, p=0.796). Among children with sickle cell disease, all of whom underwent exchange transfusion within one week prior to surgery, none experienced perioperative stroke. CONCLUSIONS Decreases in hemoglobin, hematocrit, and blood urea nitrogen between the preoperative and postoperative periods are associated with increased risk of perioperative stroke. These novel findings suggest that dilutional anemia, possibly due to standardly administered hyperhydration, may increase the risk of perioperative stroke in some children with moyamoya. Further work optimizing both mean arterial pressure and oxygen-carrying capacity in these patients, including consideration of alternative blood transfusion thresholds, is necessary.

Abstract
BACKGROUND Children with moyamoya arteriopathy are at high risk for stroke and seizures. Risk factors for seizures and the impact of seizures on neurological outcomes in children with moyamoya are unknown. METHODS This is a single-center retrospective cohort study of children with moyamoya evaluated between 2003 and 2021. Functional outcome was assessed using the Pediatric Stroke Outcome Measure (PSOM). Associations between clinical variables and seizure occurrence were assessed using univariate and multivariable logistic regression. Associations between clinical variables and final PSOM score were assessed using ordinal logistic regression. RESULTS Eighty-four patients met inclusion criteria, and 34 (40%) children experienced seizure. Factors associated with seizures included moyamoya disease (vs syndrome; odds ratio [OR] 3.43, P = 0.008) and the presence of infarcts on baseline neuroimaging (OR 5.80, P = 0.002). Factors associated with decreased likelihood of experiencing seizures included older age at initial presentation (OR 0.82, P = 0.002) and asymptomatic (radiographic) presentation (OR 0.05, P = 0.006). Both older age at presentation (adjusted OR [AOR] 0.80, P = 0.004) and incidental radiographic presentation (AOR 0.06, P = 0.022) remained significant after adjusting for potential confounders. Seizures were associated with worse functional outcomes as assessed by the PSOM (regression coefficient 2.03, P < 0.001). This association remained significant after adjusting for potential confounders (adjusted regression coefficient 1.54, P = 0.025). CONCLUSIONS Younger age and symptomatic presentation are associated with increased likelihood of seizures among children with moyamoya. Seizures are associated with worse functional outcomes. Prospective studies should clarify how seizures impact outcomes and how effective seizure treatment modifies this relationship.

Abstract
Though rare, stroke in infants and children is an important cause of mortality and chronic morbidity in the pediatric population. Neuroimaging advances and implementation of pediatric stroke care protocols have led to the ability to rapidly diagnose stroke and in many cases determine the stroke etiology. Though data on efficacy of hyperacute therapies, such as intravenous thrombolysis and mechanical thrombectomy, in pediatric stroke are limited, feasibility and safety data are mounting and support careful consideration of these treatments for childhood stroke. Recent therapeutic advances allow for targeted stroke prevention efforts in high-risk conditions, such as moyamoya, sickle cell disease, cardiac disease, and genetic disorders. Despite these exciting advances, important knowledge gaps persist, including optimal dosing and type of thrombolytic agents, inclusion criteria for mechanical thrombectomy, the role of immunomodulatory therapies for focal cerebral arteriopathy, optimal long-term antithrombotic strategies, the role of patent foramen ovale closure in pediatric stroke, and optimal rehabilitation strategies after stroke of the developing brain.

Abstract
BACKGROUND Childhood moyamoya disease (MMD) can lead to progressive and irreversible neurological impairment. Early age at onset is likely associated with a worst prognosis of the disease. The study aims to summarize the clinical characteristics of childhood MMD for supporting the diagnosis and treatment of early MMD. METHODS A retrospective study was conducted on children aged zero to 16 years who were diagnosed with MMD in the Department of Neurology and neurosurgery of our hospital from October 2016 to April 2020. The clinical characteristics of children with MMD were summarized for analysis, and the distribution of sex and initial attack type among different age groups was determined by data comparison. RESULTS The study surveyed 114 children (male to female sex ratio of 1:1.07) with MMD, and 6.1% of them had family history. The mean age of onset was 7.15 ± 3.30 years, and the peak age of onset was five to eight years. The most common initial attack type was transient ischemic attack (TIA) (62 cases, 54.4%) with limb weakness. The incidence of the initial attack type in the three age groups was varied (P < 0.05). The result of overall prognosis was good in 86 cases (89.6%). CONCLUSIONS In this study, MMD cases were mainly ischemic type and TIA was the most common initial attack type. Infant group was more prone to have cerebral infarction, whereas preschool and school-age groups tended to have TIA. The treatments and prognosis of the studied MMD cases were achieved with good outcomes.

Abstract
Patients with moyamoya arteriopathy are at high risk for developing ischemic stroke in the perioperative period. We sought to evaluate whether preoperative clinical and neuroimaging biomarkers are associated with postoperative stroke and transient ischemic attack in children with moyamoya following revascularization surgery. We performed a retrospective chart review of pediatric patients who underwent revascularization surgery for moyamoya in the last 15 years. Fifty-three patients who underwent 69 surgeries met the inclusion criteria. We recorded clinical predictors of stroke or transient ischemic attack within 7 days following surgery. We used Suzuki stage and Composite Cerebrovascular Stenosis Score to analyze neuroimaging. Significant risk factors for developing postoperative stroke or transient ischemic attack were younger age at surgery (P = .004) and transient ischemic attack less than 1 month prior to surgery (P < .001). Children under 5 and those with recent preoperative ischemic events should be the focus of investigation to evaluate modifiable risk factors and targeted interventions.

Abstract
Objective: To investigate the angioarchitectural factors associated with postoperative cerebral infarction in ischemic moyamoya disease. Methods: Data on patients who underwent surgery for ischemic MMD from 1 October 2015 to 31 October 2020, at Peking University International Hospital were collected and retrospectively analyzed. General conditions such as patient sex, age, site of surgery, preoperative manifestations such as TIA attack and old cerebral infarction, and seven angioarchitectural factors of the MMD based on DSA were selected and measured. Statistical analysis was performed by the Pearson chi-square statistic, analysis of variance (ANOVA), and multifactor logistic regression analysis. Results: Age (OR, 0.969; 95%CI, 0.939–1.000; p = 0.049), A1stenosis (OR, 5.843; 95%CI, 1.730–19.732; p = 0.004), M1stenosis (OR, 6.206; 95%CI, 2.079–18.526; p = 0.001), PCA anomalies (OR, 4.367; 95%CI, 1.452–13.129; p = 0.049), Unstable compensation (OR, 5.335; 95%CI, 1.427–19.948; p = 0.013), TIA (OR, 4.264; 95%CI, 1.844–9.863; p = 0.001), Old cerebral infarction (OR, 2.972; 95%CI, 1.194–7.397; p = 0.019). The above seven factors can be used in the regression equation to predict the probability of postoperative cerebral infarction. The prediction accuracy is 90.2%. Conclusions: Age, TIA attack, old cerebral infarction, and five angioarchitectural factors of MMD are strongly associated with postoperative cerebral infarction. Seven factors, including age, TIA attack, old infarction, and four angioarchitectural factors, can be taken to quantify the probability of surgical cerebral infarction in MMD.

Abstract
OBJECTIVE To evaluate the preoperative clinical and magnetic resonance imaging and angiography (MRI-MRA) characteristics in pediatric moyamoya patients. METHODS Analysis included 100 children with moyamoya angiopathy referred to our moyamoya center for preoperative evaluation. Clinical symptoms, neurological status using Pediatric Stroke Outcome Measurement (PSOM) and degree of disability on modified Rankin scale score (mRS) were evaluated. MRI-MRA evaluation included the assessment of ischemic lesions and involvement of posterior circulation. Data were analyzed for moyamoya disease (MMD), moyamoya syndrome (MMS) and age at disease onset. RESULTS Stroke was a common presentation in both MMD and MMS patients. TIAs and headaches/migraine were more frequent in MMD. There was no evidence of a difference in stroke burden on MRI as well as in PCA involvement between the two subgroups. Children <2 years had higher odds of having a stroke (OR 15.5, 95% CI 3.8-62.4, p < 0.001), recurrent stroke (OR 11.8, 95%CI 2.9-46.7, p < 0.001) and unfavorable mRS (≥2) (OR 4.2, 95% CI 1.3-13.7, p = 0.01) when compared to those >5 years of age. There was some evidence of association of PCA involvement with recurrent strokes (OR 3.1, CI 1.0-9.6, p = 0.05), a poor PSOM (OR 3.0, 95% CI 1.1-8.2, p = 0.04) and mRS (OR 3.1, 95% CI 1.2-8.3, p = 0.02). CONCLUSION Stroke seems to be a common presentation in both MMD and MMS patients. Early age at symptom onset and involvement of posterior circulation seem to be important risk factors for a high stroke burden and an unfavorable PSOM and mRS.

Abstract
INTRODUCTION Moyamoya arteriopathy, which can be idiopathic or associated with sickle cell disease, neurofibromatosis, Down syndrome, or cranial radiation therapy, is a progressive cerebral arteriopathy associated with high rates of incident and recurrent stroke. Little is known about how these subgroups differ with respect to clinical presentation, radiographic findings, stroke risk, and functional outcomes. METHODS Using ICD codes, we identified children ages 28 days to 18 years treated for moyamoya arteriopathy at our tertiary care center between 2003 and 2019. Demographic, clinical, and radiographic data were extracted from the medical record. The Pediatric Stroke Recurrence and Recovery Questionnaire was administered to consenting participants. RESULTS Sixty-nine patients met inclusion criteria (33 idiopathic, 18 sickle cell disease, 11 neurofibromatosis, 6 Down syndrome, 1 cranial radiation therapy). Median follow-up time was 7.7 years; 24 patients had at least 5 years of follow-up data. Frequency of stroke at presentation differed by subgroup (P < .001). Of patients with at least 2 years of follow-up, 33 (55%) experienced stroke. The proportion of patients experiencing stroke differed by subgroup (50% of idiopathic cases, 72% of sickle cell disease, 11% of neurofibromatosis, and 100% of Down syndrome, P = .003). The frequency of bilateral versus unilateral disease (P = .001) and stroke-free survival following presentation (P = .01) also differed by subgroup. CONCLUSIONS In this single-center cohort, moyamoya subgroups differed with respect to clinical and radiographic characteristics, with neurofibromatosis-associated moyamoya syndrome having a milder phenotype and Down syndrome-associated moyamoya portending a more aggressive course. These findings need confirmation in a larger, multi-center cohort with longer duration of follow-up.

Abstract
Moyamoya disease is a rare, progressive cerebral vasculopathy which most commonly presents in the first and fourth decades of life. The mainstay of treatment is surgical revascularization; without treatment, most patients experience ischemic or hemorrhagic strokes. This report reviews moyamoya disease, its associated conditions, surgical treatment techniques, and anesthetic management of patients with moyamoya disease.

Abstract
Moyamoya disease (MMD) is an unusual vasculopathy in which the blood vessels of the brain are occluded, resulting in thrombosis. When MMD occurs in association with an underlying pathology, it is known as moyamoya syndrome. The association of moyamoya syndrome with sickle cell disease is uncommon. Herein, we report a case of moyamoya syndrome in a 32-year-old male adult patient.

Abstract
Moyamoya disease (MMD) is a progressive stenosis at the terminal portion of internal carotid artery and frequently occurs in East Asian countries. The etiology of MMD is still largely unknown. We performed a case-control design with whole-exome sequencing analysis on 31 sporadic MMD patients and 10 normal controls with matched age and gender. Patients clinically diagnosed with MMD was determined by digital subtraction angiography (DSA). Twelve predisposing mutations on seven genes associated with the sporadic MMD patients of Chinese ancestry (CCER2, HLA-DRB1, NSD-1, PDGFRB, PHACTR1, POGLUT1, and RNF213) were identified, of which eight single nucleotide variants (SNVs) were deleterious with CADD PHRED scaled score > 15. Sanger sequencing of nine cases with disease progression and 22 stable MMD cases validated that SNV (c.13185159G>T, p.V265L) on PHACTR1 was highly associated with the disease progression of MMD. Finally, we knocked down the expression of PHACTR1 by transfection with siRNA and measured the cell survival of human coronary artery endothelial cell (HCAEC) cells. PHACTR1 silence reduced the cell survival of HCAEC cells under serum starvation cultural condition. Together, these data identify novel predisposing mutations associated with MMD and reveal a requirement for PHACTR1 in mediating cell survival of endothelial cells.

Abstract
Aims This study investigated the safety and efficacy of remote ischemic conditioning (RIC) on ameliorating the sequelae of ischemic moyamoya disease (iMMD). Methods A total of 30 iMMD patients underwent long‐term RIC and were followed up at 0.5, 1, and 2 years for clinical outcomes, including frequency of stroke recurrence, Patient Global Impression of Change (PGIC) scale, peak systolic velocities (PSV), and cerebral perfusion. Results During the whole RIC treatment process, no RIC‐related adverse event occurred. Only one of 30 patients suffered a onetime infarction (3.3%), and the ratios of acceptable PGIC were 88.2%, 64.3%, and 92.3% at 0.5, 1, and 2 years follow‐up. Kaplan‐Meier analysis showed the frequency of stroke recurrence was significantly reduced after RIC (P = .013). The frequency of TIA per week was 1.1 (0.6, 2.8) prior to RIC and 0.1 (0.0, 0.5) post‐RIC (P < .01). Compared to baseline, PSV values were significantly reduced after RIC treatment (P = .002 at 0.5, P = .331 at 1, and P = .006 at 2 years). In patients undergoing perfusion studies, 75% obtained improvement on followed‐up SPECT and 95% on followed‐up PET maps. Conclusions Remote ischemic conditioning may be beneficial on controlling iMMD‐induced ischemic events, relieving symptoms, and improving cerebral perfusion, without incidence of complications in this case series.

Abstract
Cerebral infarction is a common complication of sickle cell disease and may manifest as overt stroke or cognitive impairment associated with "silent" cerebral infarction on magnetic resonance imaging. Vasculopathy may be diagnosed on transcranial Doppler or magnetic resonance angiography. The risk factors in sickle cell disease for cognitive impairment, overt ischemic stroke, silent cerebral infarction, overt hemorrhagic stroke, and vasculopathy defined by transcranial Doppler or magnetic resonance angiography overlap, with severe acute and chronic anemia, acute chest crisis, reticulocytosis, and low oxygen saturation reported with the majority. However, there are differences reported in different cohorts, which may reflect age, geographic location, or neuroimaging techniques, for example, magnetic resonance imaging field strength. Regular blood transfusion reduces, but does not abolish, the risk of neurological complications in children with sickle cell disease and either previous overt stroke or silent cerebral infarction or abnormal transcranial Doppler. There are relatively few data on the use of hydroxyurea or other management strategies. Early assessment of the risk of neurocognitive complications is likely to become increasingly important in the management of sickle cell disease.
