Risk factors associated with in-hospital complications for pediatric sickle-cell disease-associated moyamoya syndrome: a nationwide cross-sectional study. Childs Nerv Syst 2024; 40:2109-2114. [PMID: 38530413 DOI: 10.1007/s00381-024-06363-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Accepted: 03/11/2024] [Indexed: 03/28/2024]
Abstract
PURPOSE Sickle-cell disease-associated moyamoya syndrome (SCD-MMS) carries a high risk for recurrent strokes and cerebrovascular morbidity in children. However, few data are available about complications that occur in children hospitalized with SCD-MMS. The purpose of this analysis was to determine the risk factors for in-hospital complications in pediatric SCD-MMS admissions, and thus aid physicians in optimizing future treatment plans. METHODS A national database of pediatric hospital admissions was examined across the years 2003-2019. ICD-9 and ICD-10 diagnosis codes were analyzed to identify discharges with a primary diagnosis of SCD-MMS and identify in-hospital complications, defined as complication-associated diagnostic codes logged during the same admission. Patient demographics, comorbidities, and hospital characteristics were examined using univariate and multivariate logistic regression analyses to determine associations with in-hospital complications. RESULTS In total, 274 admissions with a primary diagnosis of SCD-MMS were identified. During 64 (23.4%) admissions, transfusion therapy was given, and in 86 admissions (31.4%), surgical revascularization was performed. In 10 admissions (3.6%), a total of 11 in-hospital complications were identified. After multivariate regression, both comorbid chronic lung disease (adjusted OR 5.3 [1.1, 26.9], P = 0.04) and surgical revascularization (adjusted OR 10.2 [2.0, 52.4], P = 0.006) were associated with development of complications. CONCLUSIONS In this nationwide database of pediatric SCD-MMS hospitalizations, comorbid chronic lung disease and surgical revascularization were associated with development of in-hospital complications. Patients with comorbid chronic lung disease or who are admitted for revascularization may warrant closer monitoring and greater medical optimization during the hospitalization.

Abstract
BACKGROUND Improved outcomes in surgical patients have been associated with increasing volume of cases. This has led to the development of centers that facilitate care for a specific patient population. This study aimed to evaluate associations of outcomes with hospital characteristics in patients undergoing resection of malignant brain tumors. METHODS The 2016-2020 National Inpatient Sample was queried for patients undergoing resection of malignant brain tumors. Teaching hospitals with caseloads >2 standard deviations above the mean (140 cases) were categorized as high-volume centers (HVCs). Value of care was evaluated by adding one point for each of the following: short length of stay, low total charges, favorable discharge disposition, and lack of major comorbidity or complication. RESULTS In 3009 hospitals, 118,390 patients underwent resection of malignant brain tumors. HVC criteria were met by 91 (3%) hospitals. HVCs were more likely to treat patients of younger age or higher socioeconomic status (P < 0.01 for all). The Mid-Atlantic and South Atlantic regions had the highest percentage of cases and number of HVCs. Value of care was higher at HVCs (P < 0.01). Care at HVCs was associated with decreased complications (P < 0.01 for all) and improved patient outcomes (P < 0.01 for all). CONCLUSIONS Patients undergoing craniotomy for malignant brain neoplasms have superior outcomes in HVCs. Trends of centralization may reflect the benefits of multidisciplinary treatment, geographic preferences, publicity, and cultural impact. Improvement of access to care is an important consideration as this trend continues.

Abstract
BACKGROUND Studies of neurosurgical pediatric patients associate treatment at low-volume hospitals and by low-volume surgeons with increased odds of adverse outcomes. Although these associations suggest that increased centralization of care could be considered, we evaluate whether confounding endogenous factors mitigate against the proposed outcome benefits. METHODS Literature review of English language articles from 1999 to 2021. We included articles that assessed volume-outcome effects in pediatric neurosurgical patients. RESULTS Twelve papers were included from 1999 to 2021. Primary outcomes included mortality (9), length of stay (LOS) (6), complications (4), and shunt revision/failure rates (3). Volume was measured at the hospital level (8) and at the surgeon level (6). Four papers found that higher volume hospitals had lower odds of mortality. Two papers found that hospitals with higher volume had fewer complications. Two papers found that higher volume surgeons had decreased mortality (odds ratio [OR] 0.09-0.3). One paper found that high-volume surgeons had fewer complications (-2.4%; P = 0.006). After controlling for hospital factors (HF), two out of 7 analyses remained significant. Five analyses did not control for HF. CONCLUSIONS The literature consistently demonstrates a relationship between higher hospital and surgeon volume and better outcomes for pediatric neurosurgical patients. Of the 7 articles that assessed HF, only 2 analyses found that surgical volume remained associated with better outcomes. No reports assessed the degree of centralization already present. The call for centralization of pediatric care should be tempered until variables such as hospital factors, distribution of cases, and clinical thresholds can be defined and studied.

Abstract
OBJECTIVE To evaluate the management of juvenile nasopharyngeal angiofibroma (JNA) from a national perspective with outcomes comparison based on hospital volume. STUDY DESIGN Ten-year Pediatric Health Information Systems (PHIS) data analysis. METHODS The PHIS database was queried for the diagnosis of JNA. Data regarding demographics, surgical approach, embolization, length of stay, charges, readmission, and revision surgery was collected and analyzed. Hospitals were classified as low volume if fewer than 10 cases and high volume if greater than or equal to 10 cases during the study period. A random effects model compared outcomes based on hospital volume. RESULTS A total of 287 JNA patients were identified with a mean age of 13.8 (± 2.7) years. Nine hospitals were classified as high volume, accounting for a total of 121 patients. The mean length of hospitalization, blood transfusion rate, and 30-day readmissions did not differ significantly by hospital volume. Patients cared for at high-volume institutions were less likely to require postoperative mechanical ventilation (8.3% vs. 25.0%; adjusted RR = 0.32; 95% CI 0.14-0.73; p < 0.01) or return to the operating room for residual disease than patients admitted to low-volume hospitals (7.4% vs. 20.5%; adjusted RR = 0.38; 95% CI 0.18-0.79; p = 0.01). CONCLUSIONS The management of JNA is complex from both an operative and perioperative management standpoint. Over the past decade, nearly half (42.2%) of JNA patients have been managed at nine institutions in the United States. These centers have significantly lower rates of postoperative mechanical ventilation and the need for revision surgery. LEVEL OF EVIDENCE 3 Laryngoscope, 133:3216-3220, 2023.

Abstract
INTRODUCTION There is no clear consensus regarding the technique of surgical revascularization for moyamoya disease and syndrome (MMD/MMS) in the pediatric population. Previous meta-analyses have attempted to address this gap in literature but with methodological limitations that affect the reliability of their pooled estimates. This meta-analysis aimed to report an accurate and transparent comparison between studies of indirect (IB), direct (DB), and combined bypasses (CB) in pediatric patients with MMD/MMS. METHODS In accordance with PRISMA guidelines, systematic searches of Medline, Embase, and Cochrane Central were undertaken from database inception to 7 October 2022. Perioperative adverse events were the primary outcome measure. Secondary outcomes were rates of long-term revascularization, stroke recurrence, morbidity, and mortality. RESULTS Thirty-seven studies reporting 2460 patients and 4432 hemispheres were included in the meta-analysis. The overall pooled mean age was 8.6 years (95% CI: 7.7; 9.5), and 45.0% were male. Pooled proportions of perioperative adverse events were similar between the DB/CB and IB groups except for wound complication which was higher in the former group (RR = 2.54 (95% CI: 1.82; 3.55)). Proportions of post-surgical Matsushima Grade A/B revascularization favored DB/CB over IB (RR = 1.12 (95% CI 1.02; 1.24)). There was no significant difference in stroke recurrence, morbidity, and mortality. After meta-regression analysis, year of publication and age were significant predictors of outcomes. CONCLUSIONS IB, DB/CB are relatively effective and safe revascularization options for pediatric MMD/MMS. Low-quality GRADE evidence suggests that DB/CB was associated with better long-term angiographic revascularization outcomes when compared with IB, although this did not translate to long-term stroke and mortality benefits.

Abstract
OBJECTIVES The clinical value of antiplatelet therapy (APT) for moyamoya disease (MMD) remains controversial. Our study attempts to clarify the value of APT in this disease. METHODS We collected basic information, treatment strategies, and prognostic information on patients with MMD from 2010 to 2022 at our center. The data were divided into two groups, depending on whether APT was used or not, and compared by Pearson Chi-Square, Fisher's exact test, or Wilcoxon rank-sum test. We used propensity scores or inverse probability of treatment weighting to balance the covariates. Following this, we performed a meta-analysis of APT use in MMD. RESULTS 177 patients were enrolled, with a median follow-up of 41.1 months. APT did not affect the prognosis of patients with perioperative MMD, ischemic MMD, or asymptomatic MMD (P > 0.05), without increasing cerebral hemorrhagic risk. In contrast, APT was found to reduce mortality among patients with hemorrhagic MMD (P = 0.019), without affecting functional status, increasing stroke risk, or causing intracerebral hemorrhage (P > 0.05). But the small group cannot show the effect of APT. Our meta-analysis included nine articles involving 28,925 patients with MMD. It showed that APT could reduce stroke risk (odds ratio, OR = 0.57, 95% CI 0.49 to 0.65) and the Modified Rankin Scale (mRS) (weighted mean difference, WMD = - 0.07, 95% CI 0.14-0.00) during follow-up. The cohort study has limited weight (1.97% and 19.29%) in the meta-analysis. CONCLUSION Although the limited number of included documents, APT could be beneficial to the prognosis of MMD.

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
Recent next-generation DNA and RNA sequencing studies of congenital and pediatric cerebrovascular anomalies such as moyamoya disease, arteriovenous malformations, vein of Galen malformations, and cavernous malformations have shed new insight into the genetic regulation of human cerebrovascular development by implicating multiple novel disease genes and signaling pathways in the pathogenesis of these disorders. These diseases are now beginning to be categorized by molecular disruptions in canonical signaling pathways that impact the differentiation and proliferation of specific venous, capillary, or arterial cells during the hierarchical development of the cerebrovascular system. Here, the authors discuss how the continued study of these and other congenital cerebrovascular conditions has the potential to replace the current antiquated, anatomically based disease classification systems with a molecular taxonomy that has the potential to increase precision in genetic counseling, prognostication, and neurosurgical and endovascular treatment stratification. Importantly, the authors also discuss how molecular genetic data are already informing clinical trials and catalyzing the development of targeted therapies for these conditions historically considered as exclusively neurosurgical lesions.

Abstract
BACKGROUND Markers of quality of care in various surgical specialties have been shown to correlate with hospital volumes. This study investigates the effect of hospital volume and patient-related factors on the outcomes of children undergoing brain tumor resection. METHODS We examined the data within the Pediatric Health Information System (PHIS) for children aged zero to 17 years undergoing brain tumor resection between 2016 and 2020. Length of hospital stay (LOS), costs, and reoperation rates were analyzed for associations with hospital case-volume, patient factors, and other hospital-related factors. RESULTS A total of 2568 patients were included in this PHIS analysis. After adjusting for covariates, care provided by high-case-volume hospitals led to shorter LOS (P = 0.01). The effect of hospital case-volume on median cost was present on univariate analysis (US $63,845 at low-volume hospital versus US $54,909 at high-volume hospital, P = 0.002); this finding was attenuated by LOS. A trend was observed between reoperation rates and hospital case-volume, with lowest quartile volume hospitals having higher odds of reoperation than hospitals with volumes in the highest quartile (P = 0.06). Racial and ethnic minorities, medical comorbidities, and other sociodemographic factors were associated with poorer outcomes following surgery. CONCLUSIONS Centering care around high-case-volume hospitals can potentially lead to shorter hospital stays and decreased costs for children with brain tumors. This PHIS article highlights the association of the studied outcomes with certain sociodemographic factors and illustrates that inequalities in pediatric health care still exist. Further efforts are required to understand and eliminate these potentially harmful differences.

Abstract
OBJECTIVE Obtaining operative experience for the treatment of rare conditions in children represents a challenge for pediatric neurosurgeons. Starting in November 2017, a surgeon was mentored in surgical revascularization (SR) for pediatric moyamoya with a view to service development and sustainability. The aim of this audit was to evaluate early outcomes of SR for pediatric moyamoya during and following a surgical mentorship. METHODS A retrospective cohort study with chart/database review of consecutive moyamoya surgeries performed by a new attending surgeon (between November 2017 and March 2020) was compared to a previously published cohort from the authors' institution in terms of clinical and angiographic outcomes, complications, operating time, and length of stay. A standardized technique of encephaloduroarteriomyosynangiosis with the superficial temporal artery was used. RESULTS Twenty-two children underwent 36 indirect SRs during the study period. Patient demographics were similar between cohorts. The first group of 6 patients had 11 SRs performed jointly by the new attending surgeon mentored by an established senior surgeon (group A), followed by 10 patients with 16 SRs performed independently by the new attending surgeon (group B). The last 6 patients had 9 SRs with the new attending surgeon mentoring a senior fellow (group C) in performing SR. Good angiographic collateralization (Matsushima grades A and B) was observed in 80% of patients, with similar proportions across all 3 groups. A total of 18/19 symptomatic patients (95%) derived symptomatic benefit. There was no perioperative death and, compared to the historical cohort, a similar proportion had a recurrent arterial ischemic event (i.e., acute ischemic stroke) necessitating a second SR (1/22 vs 3/73). Operative times were longest in group C, with no difference in length of hospital stay among the 3 groups. CONCLUSIONS Early outcomes demonstrate the feasibility of mentorship for safely incorporating new neurosurgeons in sustaining and developing a tertiary-level surgical service.

Abstract
OBJECTIVE Healthcare disparities are widely described in adults, but barriers affecting access to care for pediatric patients with moyamoya disease (MMD) are unknown. Understanding socioeconomic factors impacting hospital access and outcomes is necessary to address pediatric healthcare disparities. METHODS In this cross-sectional observational study, the Kids' Inpatient Database was used to identify patients admitted with a primary diagnosis of MMD from 2003 to 2016. Patients ≤ 18 years with a primary diagnosis of MMD based on International Classification of Diseases (ICD) codes were included. Hospital admissions were queried for use of cerebral revascularization based on ICD procedure codes. RESULTS Query of the KID yielded 1449 MMD hospitalizations. After multivariable regression, Hispanic ethnicity (OR 0.52 [95% CI 0.33-0.81], p = 0.004) was associated with lack of surgical revascularization. Private insurance (OR 1.56 [95% CI 1.15-2.13], p = 0.004), admissions at medium- and high-volume centers (OR 2.01 [95% CI 1.42-2.83], p < 0.001 and OR 2.84 [95% CI 1.95-4.14], p < 0.001, respectively), and elective hospitalization (OR 3.37 [95% CI 2.46-4.64], p < 0.001) were positively associated with revascularization. Compared with Caucasian race, Hispanic ethnicity was associated with increased mean (± SEM) length of stay by 2.01 ± 0.70 days (p = 0.004) and increased hospital charges by $24,333.61 ± $7918.20 (p = 0.002), despite the decreased utilization of surgical revascularization. Private insurance was associated with elective admission (OR 1.50 [95% CI 1.10-2.05], p = 0.01) and admission to high-volume centers (OR 1.90 [95% CI 1.26-2.88], p = 0.002). African American race was associated with the development of in-hospital complications (OR 2.52 [95% CI 1.38-4.59], p = 0.003). CONCLUSIONS Among pediatric MMD hospitalizations, multiple socioeconomic factors were associated with access to care, whether surgical treatment is provided, and whether in-hospital complications occur. These results suggest that socioeconomic factors are important drivers of healthcare disparities in children with MMD and warrant further study.

Abstract
Moyamoya syndrome increases the risk of stroke in sickle cell disease, but revascularization surgery can modify this risk. Collaborative management between hematology and neurosurgery offers effective strategies to reduce stroke risk in these patients. We describe a challenging case where a patient with sickle cell disease undergoing standard of care management as prescribed by the Stroke Prevention Trial in Sickle Cell Anemia (STOP) and revascularization with pial synangiosis subsequently developed rapidly progressive disease in other cerebral vessels and suffered ischemic hemispheric stroke. This case demonstrates the success of management in accordance with American Heart Association (AHA) and American Stroke Association (ASA) guidelines, but also demonstrates critical areas where we lack understanding of disease progression.

Abstract
BACKGROUND AND PURPOSE Cerebrovascular reserve (CVR) inversely correlates with stroke risk in children with Moyamoya disease and may be improved by revascularization surgery. We hypothesized that acetazolamide-challenged arterial spin labeling MR perfusion quantifies augmentation of CVR achieved by revascularization and correlates with currently accepted angiographic scoring criteria. METHODS We retrospectively identified pediatric patients with Moyamoya disease or syndrome who received cerebral revascularization at ≤18 years of age between 2012 and 2019 at our institution. Using acetazolamide-challenged arterial spin labeling, we compared postoperative CVR to corresponding preoperative values and to postoperative perfusion outcomes classified by Matsushima grading. RESULTS In this cohort, 32 patients (17 males) with Moyamoya underwent 29 direct and 16 indirect extracranial-intracranial bypasses at a median 9.7 years of age (interquartile range, 7.6-15.7). Following revascularization, median CVR increased within the ipsilateral middle cerebral artery territory (6.9 mL/100 g per minute preoperatively versus 16.5 mL/100 g per minute postoperatively, P<0.01). No differences were observed in the ipsilateral anterior cerebral artery (P=0.13) and posterior cerebral artery (P=0.48) territories. Postoperative CVR was higher in the ipsilateral middle cerebral artery territories of patients who achieved Matsushima grade A perfusion, in comparison to those with grades B or C (25.8 versus 17.5 mL, P=0.02). The method of bypass (direct or indirect) did not alter relative increases in CVR (8 versus 3.8 mL/100 g per minute, P=0.7). CONCLUSIONS Acetazolamide-challenged arterial spin labeling noninvasively quantifies augmentation of CVR following surgery for Moyamoya disease and syndrome.

Abstract
Moyamoya disease (MMD) is a complex and incompletely-understood cerebrovascular pathological entity that requires thorough clinical and imaging evaluation. Moyamoya is rare, thereby making the establishment of an effective, thorough and interdisciplinary patient evaluation protocol challenging, even within specialized referral centers. Nevertheless, implementation of such a protocol is crucial in order to provide the best possible evaluation and treatment for MMD patients. Here, we describe our institution's implementation of, rationale for, and experience with a comprehensive multidisciplinary collaboration and evaluation strategy for adult patients with moyamoya. This evaluation course consists of, first of all, a thorough clinical and laboratory evaluation with a vascular neurologist. This is followed by a comprehensive imaging assessment which evaluates angiographic and parenchymal features, in addition to cerebrovascular functionality. Finally, appropriate referrals are made to consulting services as indicated, which includes vascular neurosurgery. These steps are described in detail herein.

Abstract
Objective Moyamoya disease (MMD) is a vasculopathy of the internal carotid arteries with ischemic and hemorrhagic sequelae. Surgical revascularization confers upfront peri-procedural risk and costs in exchange for long-term protective benefit against hemorrhagic disease. The authors present a cost-effectiveness analysis (CEA) of surgical versus non-surgical management of MMD. Methods A Markov Model was used to simulate a 41-year-old suffering a transient ischemic attack (TIA) secondary to MMD and now faced with operative versus nonoperative treatment options. Health utilities, costs, and outcome probabilities were obtained from the CEA registry and the published literature. The primary outcome was incremental cost-effectiveness ratio which compared the quality adjusted life years (QALYs) and costs of surgical and nonsurgical treatments. Base-case, one-way sensitivity, two-way sensitivity, and probabilistic sensitivity analyses were performed with a willingness to pay threshold of $50,000. Results The base case model yielded 3.81 QALYs with a cost of $99,500 for surgery, and 3.76 QALYs with a cost of $106,500 for nonsurgical management. One-way sensitivity analysis demonstrated the greatest sensitivity in assumptions to cost of surgery and cost of admission for hemorrhagic stroke, and probabilities of stroke with no surgery, stroke after surgery, poor surgical outcome, and death after surgery. Probabilistic sensitivity analyses demonstrated that surgical revascularization was the cost-effective strategy in over 87.4% of simulations. Conclusions Considering both direct and indirect costs and the postoperative QALY, surgery is considerably more cost-effective than non-surgical management for adults with MMD.

Abstract
BACKGROUND AND PURPOSE There has been an increasing prevalence of Moyamoya disorder (MMD) reported from recent US literature. There is a paucity of data available regarding trends of prevalence and epidemiological factors in the United States. To goal of this study was to test the hypotheses that racial-, sex-specific MMD hospitalizations and epidemiological factors have been increasing in the United States over the last decade. METHODS In this retrospective observational study, using the National Inpatient Sample (NIS) database from 2005 to 2016, MMD-related hospitalizations in patients aged ≥18 years were identified. Trends of epidemiological factors were analyzed over time using the linear regression model with the significance of differences in trend over time assessed using the Wald test. Sex- and race-specific burden of MMD were calculated using the annual US Census data. Joinpoint regression model was used to evaluate trends of hospitalizations over time. RESULTS A total of 24,484 adult hospitalizations were identified from January 2005 to September 2015 after excluding <18 years. Among them, approximately ~90% were aged ≤60 years, and 73.5% were females. The most common vascular and non-vascular presentations were ischemic stroke (17.3%) and seizures (21%), respectively. The trend of antithrombotic therapy has increased, while extracranial-intracranial bypass has remained stagnant. The actual average hospitalizations of MMD was 10.4 cases/ million population/year (range 4.1-17.9) and varied significantly by sex (females 14.7 [range 6.2-23.6] and males 5.9 [range 1.8-11.9]) over the 2005 to 2016 study period. The burden of hospitalizations also differed by race (African Americans 40.6 [range 32.8-63.7], Asians 24.8 [15.4-34.8], Non-Hispanic Whites 8.1 [range 6.4-11.5], and Hispanics 8.4 [2.8-12.8]) over the 2010 to 2016 study period. Joinpoint regression analysis showed an increasing overall MMD trend across the study period (+11.7%; P < 0.001), which was higher in males (+14.5% vs. +10.7%; P < 0.001). The Hispanic group had significantly increased hospitalizations over the years (+20.2%; P < 0.001). CONCLUSION Although overall more prevalent in females, MMD-related hospitalizations are increasing more rapidly in males. Among the racial subpopulations, African Americans had the highest MMD-related hospitalizations, even higher than Asian Americans. MMD-related hospitalizations have increased quicker in Hispanics than in any other racial group.

Abstract
AbstractMoyamoya is a progressive arteriopathy of the intracranial vasculature, predominantly affecting the terminal branches of the internal carotid artery. Treatment is predicated on surgical revascularization to reduce the risk of stroke. For patients diagnosed and treated as children, it is important to recognize the long-term implications of the disease, for example, that moyamoya is treatable, but not curable. Pediatric moyamoya patients face unique challenges as they transition to adulthood as a consequence of the chronic nature of this disorder. Successful long-term care requires a strategy that incorporates ongoing longitudinal disease monitoring, coordination of care between physician teams, and anticipation of socioeconomic factors that change over time. This article provides an approach to transition care to adult caregivers for pediatric moyamoya patients with a specific focus on the three key stakeholders in the process: the neurosurgeon, the primary care physician, and the individual patient.

Abstract
OBJECTIVES To recognize the national trends in management of pediatric craniopharyngioma and to address the significant predictors of discharge disposition. METHODS We utilized the Kids' Inpatient Database (KID), a pediatric inpatient sample generated by the Healthcare Cost and Utilization Project (HCUP) triennially from 1997 to 2016. RESULTS KID contains 2141 pediatric craniopharyngioma admissions. Patient demographics had no effect on discharge disposition. Based on the multivariable logistic regression analysis, we confirmed a significantly higher non-routine discharge rate among patients with hydrocephalus (P = 0.01). Patients who developed diabetes insipidus were at higher risk for non-routine discharge (P = 0.02). Admission of patients to a freestanding children's hospital increased the likelihood of routine discharge (P = 0.001). CONCLUSION Hydrocephalus, diabetes insipidus, and admission to a freestanding children's hospital are significant independent predictors of discharge disposition.

Abstract
We report a case of central retinal artery occlusion (CRAO) leading to unilateral blindness occurring in a moyamoya patient 30 years after successful pial synangiosis when she was 6 years old. Imaging studies at the time of the CRAO revealed total occlusion of the ipsilateral cervical and intracranial internal carotid artery, a vessel shown to be patent on MRI/MRA studies for decades previously. This case demonstrates that long-term follow-up of operated moyamoya patients may reveal late secondary complications, of which physicians, patients, and families need to be aware.

Abstract
Low grade gliomas (LGGs) affect young individuals in the prime of life. Management may alternatively include biopsy and observation or surgical resection. Recent evidence strongly favors maximal and supramaximal resection of LGGs in optimizing survival metrics. Awake craniotomy with cortical mapping and electrical stimulation along with other preoperative and intraoperative surgical adjuncts, including intraoperative magnetic resonance and diffusion tensor imaging, facilitates maximization of resection and eschews precipitating neurological deficits. Intraoperative imaging permits additional resection of identified residual to be completed within the same surgical session, improving extent of resection and consequently progression free and overall survival. These resources are available in only a few centers throughout the United States, raising an ethical dilemma as to where patients harboring LGGs should most appropriately be treated.

Abstract
Moyamoya disease in adults is a chronic, progressive disorder characterized by fine collateral vessel networks in the brain. The disorder can lead to negative mood and stress, which, left unresolved, may increase adverse health outcomes. We conducted a cross-sectional survey to examine stress and mood of adults with moyamoya disease. Participants were recruited at a university hospital in Seoul, Korea. Data were collected through questionnaires and review of participants' electronic medical records. A total of 109 adults participated. Significant correlations were found between perceived stress, anxiety, and depression. Adults with moyamoya disease experience anxiety, depression, and stress related to the risk of cerebral hemorrhage or ischemia, similar to those with other cerebrovascular disease. If negative mood and stress were uncontrolled, those can cuase adverse health outcomes. Health professionals caring for people with moyamoya disease should carefully observe their stress and mood and develop interventions tailored to stages of disease to help them manage. The study results provide baseline information for understanding the level of, and the factors associated with, stress and mood.

J Neurosurg Pediatr 2019; 24:397-406. [PMID: 31374543 DOI: 10.3171/2019.5.peds19155] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2019] [Accepted: 05/16/2019] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Comprehensive multicenter data on the surgical treatment of pediatric cerebrovascular malformations (CVMs) in the US are lacking. The goal of this study was to identify national trends in patient demographics and assess the effect of hospital case volume on outcomes. METHODS Admissions for CVMs (1997-2012) were identified from the nationwide Kids' Inpatient Database. Admissions with and without craniotomy were reviewed separately. Patients were categorized by whether they were treated at low-, medium-, or high-volume centers (< 10, 10-40, > 40 cases/year, respectively). A generalized linear model was used to evaluate the association of hospital pediatric CVM case volume and clinical variables assessing outcomes. RESULTS Among the 9655 patients, 1828 underwent craniotomy and 7827 did not. Patient age and race differed in the two groups, as did the rate of private medical payers. High-volume hospitals had fewer nonroutine discharges (11.2% [high] vs 16.4% [medium] vs 22.3% [low], p = 0.0001). For admissions requiring craniotomy, total charges ($106,282 [high] vs $126,215 [medium] vs $134,978 [low], p < 0.001) and complication rates (0.09% [high] vs 0.11% [medium] vs 0.16% [low], p = 0.001) were lower in high-volume centers. CONCLUSIONS This study revealed that further investigation may be needed regarding barriers to surgical treatment of pediatric CVMs. The authors found that surgical treatment of pediatric CVM at high-volume centers is associated with significantly fewer complications, better dispositions, and lower costs, but for noncraniotomy patients, low-volume centers had lower rates of complications and death and lower costs. These findings may support the consideration of appropriate referral of CVM patients requiring surgery or with intracranial hemorrhage toward high-volume, specialized centers.

Abstract
BACKGROUND International trials suggest benefit of revascularization surgery (RS) for moyamoya disease (MMD). However, nationally representative US data on demographics and outcomes after RS in MMD are lacking. AIMS To estimate causes and rates of readmission after RS for MMD. METHODS In the Nationwide Readmissions Database, index admissions for ECICB for MMD and readmissions for ischemic stroke (IS), subarachnoid hemorrhage (SAH), and intracerebral hemorrhage (ICH) were identified using validated International Classification of Diseases, Ninth Revision, Clinical Modification codes. We summarized demographics and comorbidities, and calculated 30-, 60-, and 90-day readmission rates per 100,000 index admissions. RESULTS Among 201 index admissions for RS for MMD, mean age (SD) was 41.7 (12.6) years; 75% were female; 24% had diabetes; 53% had hypertension; 40% had hypercholesterolemia; 3% had ICH; 16% had IS; and 1% had SAH. RS was performed at large hospitals in 83%, urban hospitals in 85%, and teaching hospitals in 97%. 80% were discharged home. 34% had a readmission during follow-up. Leading reasons for readmission up to 90 days included MMD (62%), postoperative infection (10%), sickle cell crisis (4%), ischemic stroke (4%), epilepsy (2%), subdural hemorrhage (2%) and headache (2%). Readmission rates (per 100,000 index admissions) were 559 at 30 days, 1829 at 60 days, and 2027 at 90 days for IS. There were no readmissions for SAH or ICH. CONCLUSIONS This analysis of nationally representative US data suggests that although readmission after RS for MMD is not uncommon, cerebral hemorrhagic events during the 90-day postoperative period are rare.

Proposing a validated clinical app predicting hospitalization cost for extracranial-intracranial bypass surgery. PLoS One 2017; 12:e0186758.

Abstract
OBJECT United States healthcare reforms are focused on curtailing rising expenditures. In neurosurgical domain, limited or no data exists identifying potential modifiable targets associated with high-hospitalization cost for cerebrovascular procedures such as extracranial-intracranial (ECIC) bypass. Our study objective was to develop a predictive model of initial cost for patients undergoing bypass surgery. METHODS In an observational cohort study, we analyzed patients registered in the Nationwide Inpatient Sample (2002-2011) that underwent ECIC bypass. Split-sample 1:1 randomization of the study cohort was performed. Hospital cost data was modelled using ordinary least square to identity potential drivers impacting initial hospitalization cost. Subsequently, a validated clinical app for estimated hospitalization cost is proposed (https://www.neurosurgerycost.com/calc/ec-ic-by-pass). RESULTS Overall, 1533 patients [mean age: 45.18 ± 19.51 years; 58% female] underwent ECIC bypass for moyamoya disease [45.1%], cerebro-occlusive disease (COD) [23% without infarction; 12% with infarction], unruptured [12%] and ruptured [4%] aneurysms. Median hospitalization cost was $37,525 (IQR: $16,225-$58,825). Common drivers impacting cost include Asian race, private payer, elective admission, hyponatremia, neurological and respiratory complications, acute renal failure, bypass for moyamoya disease, COD without infarction, medium and high volume centers, hospitals located in Midwest, Northeast, and West region, total number of diagnosis and procedures, days to bypass and post-procedural LOS. Our model was validated in an independent cohort and using 1000-bootstrapped replacement samples. CONCLUSIONS Identified drivers of hospital cost after ECIC bypass could potentially be used as an adjunct for creation of data driven policies, impact reimbursement criteria, aid in-hospital auditing, and in the cost containment debate.
