Ghosh A, Sareen K, Thomas P. Approach to adult Moyamoya disease presenting as bilateral anterior circulation infarcts: a case report. Brain Inj 2024:1-4. [PMID: 39066895 DOI: 10.1080/02699052.2024.2385375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2024] [Revised: 07/21/2024] [Accepted: 07/22/2024] [Indexed: 07/30/2024]
Abstract
Moyamoya disease (MMD) is a rare progressive condition of unknown etiology that affects the blood vessels in the brain and is characterized by narrowing or stenosis of the distal parts of the internal carotid and major intracranial arteries, leading to the development of fragile collateral supplies. This makes it a significant causative factor for both ischemic strokes as well as intracerebral hemorrhages. As per the recommendations by the Research Committee on Moyamoya disease in 2021, the diagnostic criteria for MMD are essentially based on indicative radiological findings on cerebral angiography or MRI Brain and MRA, after excluding possible differentials. In this case report, we present the case of a 45-year-old Asian lady who presented with sudden-onset headaches and right-sided weakness. Her admission non-contrast CT brain scan was undiagnostic. MRI brain and MRA scans revealed bilateral anterior circulation watershed infarcts of variable age along with supra-clinoid stenosis. She was initially treated with steroids for vasculitis after discussions with a multidisciplinary team involving neurologists, stroke physicians and neuro-radiologists; however, further imaging revealed a diagnosis of MMD, and she was subsequently referred for revascularization surgery. Given the limited number of similarly documented cases, we hope this report will contribute to the knowledge base.

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
OBJECTIVE The characteristics of pregnancy and delivery in patients with moyamoya disease (MMD) remain unclear. We retrospectively investigated perinatal outcomes in patients with MMD to evaluate the risks associated to this condition. MATERIALS AND METHODS Clinical data of women with MMD who delivered at the University of Tokyo Hospital between 2000 and 2021 were collected. Maternal characteristics including genetic data, obstetric complications, method of delivery and anesthesia, neonatal outcomes, neurological events during pregnancy, delivery, and postpartum course, were reviewed. RESULTS Thirteen pregnancies with MMD were identified. The median maternal age was 30 years. The initial clinical symptoms were identified as transient ischemic attack, infarction, and headache. Eight patients had a history of bypass surgery. The median gestational age at delivery was 37 weeks. DNA samples were collected from five patients, responsible for six pregnancies. Of these six cases, five had the RNF213 c.14429G > A (p.Arg4810Lys) heterozygous variant. Of the 13 pregnancies, seven had hypertensive disorder of pregnancy (HDP). Additionally, three of five pregnancy cases with RNF213 p.Arg4810Lys heterozygous variant presented with HDP. Nine patients underwent cesarean section, and four delivered vaginally with epidural anesthesia. One case of ischemic stroke was confirmed during the postpartum period. Regarding newborns, neither Apgar scores lower than 7 nor neonatal intensive care unit admissions were reported. CONCLUSIONS This study suggests that the frequency of HDP is higher in patients with MMD compared to those with normal pregnancies. Strict blood pressure control should be performed in patients with MMD during pregnancy and postpartum period.

Abstract
PURPOSE OF REVIEW Uncommon causes of stroke merit specific attention; when clinicians have less common etiologies of stoke in mind, the diagnosis may come more easily. This is key, as optimal management will in many cases differs significantly from "standard" care. RECENT FINDINGS Randomized controlled trials (RCT) on the best medical therapy in the treatment of cervical artery dissection (CeAD) have demonstrated low rates of ischemia with both antiplatelet and vitamin K antagonism. RCT evidence supports the use of anticoagulation with vitamin K antagonism in "high-risk" patients with antiphospholipid antibody syndrome (APLAS), and there is new evidence supporting the utilization of direct oral anticoagulation in malignancy-associated thrombosis. Migraine with aura has been more conclusively linked not only with increased risk of ischemic and hemorrhagic stroke, but also with cardiovascular mortality. Recent literature has surprisingly not provided support the utilization of L-arginine in the treatment of patients with mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS); however, there is evidence at this time that support use of enzyme replacement in patients with Fabry disease. Additional triggers for reversible cerebral vasoconstriction syndrome (RCVS) have been identified, such as capsaicin. Imaging of cerebral blood vessel walls utilizing contrast-enhanced MRA is an emerging modality that may ultimately prove to be very useful in the evaluation of patients with uncommon causes of stroke. A plethora of associations between cerebrovascular disease and COVID-19 have been described. Where pertinent, authors provide additional tips and guidance. Less commonly encountered conditions with updates in diagnosis, and management along with clinical tips are reviewed.

Abstract
Differences exist between genders in intracerebral hemorrhage cause, epidemiology, and outcomes. These gender differences are in part attributable to physiologic differences; however, demographic, social/behavioral risk factors, along with health care system variation and potential family and/or clinician bias play a role as well. These factors vary from region to region and interact, making comprehensive and definitive conclusions regarding sex differences a challenging task. Differences between the genders in intracerebral hemorrhage epidemiology and extensive differences in underlying pathophysiology, intervention, risk factors, and outcome are all discussed.

Clinical Efficacy of Superficial Temporal Artery-middle Cerebral Artery Bypass Grafting Surgery Combined With Temporal Muscle Patch on Patients With Moyamoya Disease. J Craniofac Surg 2023; 34:643-649. [PMID: 36731073 PMCID: PMC9944694 DOI: 10.1097/scs.0000000000008992] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Accepted: 08/01/2022] [Indexed: 02/04/2023] Open
Abstract
OBJECTIVE To analyze the clinical efficacy of superficial temporal artery-middle cerebral artery (STA-MCA) bypass grafting surgery combined with temporal muscle patch and STA-MCA bypass grafting surgery alone on patients with moyamoya disease. METHODS Totally 73 patients confirmed with moyamoya disease in our hospital between January 2019 and December 2021 were enrolled. Among them, 43 patients treated with STA-MCA bypass grafting surgery combined with temporal muscle patch were assigned to the experiment group, whereas 30 patients treated with STA-MCA bypass grafting surgery alone to the control group. The following items of the 2 groups were compared: clinical efficacy, total effective rate, and disease control rate 6 months after surgery, the changes of modified Rankin Scale (mRS) and Karnofsky performance scale (KPS) scores before and on the seventh day and 6 months after surgery, and changes of Glasgow coma scale scores before and 24 hours after surgery. In addition, the incidences of cerebral ischemia and cerebral hemorrhage within 1 year after surgery were counted. The cerebral perfusion-associated indexes including relative mean transit time (rMTT), relative time-to-peak, relative cerebral blood flow (rCBF), and relative cerebral blood volume (rCBV) on the seventh day and 6 months after surgery were compared between the 2 groups, and the predictive value of cerebral perfusion-associated indexes before surgery for clinical efficacy on patients was analyzed. RESULTS The Glasgow coma scale score after surgery ( P >0.05) was similar between the 2 groups, but the clinical efficacy and total effective rate of the 2 groups were notably different (both P <0.05). Compared with those before surgery, mRS scores of both groups declined, whereas KPS scores increased (both P <0.05) on the seventh day after surgery. In addition, compared with those before surgery and on the seventh day after surgery, mRS scores of both groups decreased 6 months after surgery, whereas KPS scores increased (both P <0.05). Both the groups showed decreased rMTT and rTPP, and increased rCBF and rCBV on the seventh day after surgery than those before surgery (all P <0.05). In addition, both the groups still showed decreased rMTT and rTPP, and increased rCBF and rCBV 6 months after surgery than those before surgery and on the seventh day after surgery (all P <0.05). Most notably, the experimental group displayed improved cerebral perfusion-associated indexes than the control group 6 months after surgery (all P <0.05). The relief group showed notably higher rCBF and rCBV levels than the nonrelief group (both P <0.05). According to ROC analysis, the areas under the curves of rCBF and rCBV in forecasting the clinical efficacy on patients were 0.842 and 0.823, respectively. CONCLUSION Superficial temporal artery-middle cerebral artery bypass grafting surgery combined with temporal muscle patch can deliver a higher total clinical curative rate for patients with moyamoya disease and can alleviate their coma.

Abstract
Objective The convolutional neural network (CNN) was used to improve the accuracy of digital subtraction angiography (DSA) in diagnosing moyamoya disease (MMD), providing a new method for clinical diagnosis of MMD. Methods A total of 40 diagnosed with MMD by DSA in the neurosurgery department of our hospital were included. At the same time, 40 age-matched and sex-matched patients were selected as the control group. The 80 included patients were divided into training set (n = 56) and validation set (n = 24). The DSA image was preprocessed, and the CNN was used to extract features from the preprocessed image. The precision and accuracy of the preprocessed image results were evaluated. Results There was no significant difference in baseline data between the training set and validation set (P > 0.05). The precision and accuracy of the images before processing were 79.68% and 81.45%, respectively. After image processing, the precision and accuracy of the model are 96.38% and 97.59%, respectively. The area under the curve of the CNN algorithm model was 0.813 (95% CI: 0.718-0.826). Conclusion This diagnostic method based on CNN performs well in MMD detection.

Abstract
Background Physiologic changes during pregnancy affect the development of postpartum cerebrovascular disease (CVD) in women with Moyamoya disease. Due to the rare prevalence of Moyamoya disease and its large regional variations, large-scale based studies on the risk of CVD after delivery have not been conducted. This study aimed to evaluate whether women with Moyamoya disease have an increased risk of CVD after delivery. Methods Research data was collected from the National Health Insurance Claims Database of the Health Insurance Review and Assessment Service. Patients who delivered in Korea from 2007 to 2014 were enrolled in this study. We classified women as having CVD if they were diagnosed with any of the following conditions between delivery and December 31, 2016; cerebral infarction (I63.X in the International Classification of Diseases-10th Revision [ICD-10]) and/or intracranial hemorrhage (I61.X, I62.X in ICD-10) and/or subarachnoid hemorrhage (I60.X in ICD-10). Women with Moyamoya disease were identified as having I67.5 in ICD-10. We matched the study cohort by the ratio of 1:10 to analyze the risk CVD occurrence. The matching technique applied in this study was based on the variables of age and parity. To evaluate the adjusted hazard ratio (HR) for CVD in women with Moyamoya disease, we used multivariate Cox proportional hazard regression. Results Among a total of 3,611,216 Korean women who underwent delivered, we identified 412 women with Moyamoya disease diagnosis and 1420 age- and parity-matched women without Moyamoya disease (control). Compared to the control group, women with Moyamoya disease had a significantly higher rate of Cesarean section, overt DM, and essential hypertension (all p < 0.0001). Among women with Moyamoya disease, 55 (13.35%) women developed CVD within the follow-up postpartum period. The presence of Moyamoya disease was associated with an increased risk of CVD after delivery (adjusted HR 37.42; 95% confidence interval (CI) 17.50-80.02 within 2.3 years) after adjusting for pregnancy-induced hypertension, gestational diabetes mellitus, pregestational diabetes, chronic hypertension. Conclusion This population based study showed that the occurrence rate of CVD after delivery was higher in women with Moyamoya disease than in those without. Therefore, careful and long-term postpartum surveillance is required for women with Moyamoya disease.

Abstract
Neurological and neurosurgical conditions complicating pregnancy may precipitate considerable concern regarding the risk of complications, and uncertainty regarding the preferred mode of delivery and anaesthesia. Caesarean section is known to be associated with significantly increased risk of adverse maternal outcomes compared with vaginal delivery in healthy pregnancy. Nevertheless, a common perception exists among the general population and some health professionals that caesarean section is safer for the mother and baby in high-risk pregnancies. This manuscript examines the literature regarding the risks and outcomes related to mode of delivery in pregnancy complicated by disorders of the central nervous system. With the exception of women with raised intracranial pressure, and some women with Von Hippel-Lindau syndrome, the available evidence suggests that the mode of delivery should be based upon obstetric indications.

Abstract
BACKGROUND Moyamoya disease, a rare chronic cerebrovascular disease with a fragile vascular network at the base of the brain, can cause ischemic or hemorrhagic strokes or seizures. Precise blood pressure control and adequate analgesia are important for patients with moyamoya disease to prevent neurological events such as ischemia and hemorrhage. This study aimed to compare the intraoperative mean arterial pressure of pregnant women with moyamoya disease according to the mode of anesthesia (general anesthesia versus spinal anesthesia) used during cesarean delivery. METHODS We retrospectively reviewed the medical records of 87 cesarean deliveries in 74 patients who had been diagnosed with moyamoya disease before cesarean delivery. The primary outcome, intraoperative maximum mean arterial pressure during anesthesia, was compared according to the type of anesthesia administered (general versus spinal anesthesia). Other perioperative hemodynamic data (lowest mean arterial pressure, incidence of hypotension, vasopressor use, and antihypertensive agent use), maternal neurologic symptoms, neonatal outcomes (Apgar scores <7, ventilatory support, and intensive care unit admission), maternal and neonatal length of stay, postoperative pain scores, and rescue analgesic use were assessed as secondary outcomes. RESULTS While the lowest blood pressure during anesthesia and incidence of hypotension did not differ between the 2 groups, the maximum mean arterial pressure during anesthesia was lower in the spinal anesthesia group than that in the general anesthesia group (104.8 ± 2.5 vs 122.0 ± 4.6; P = .002). Study data did not support the claim that maternal neurologic symptoms differ according to the type of anesthesia used (5.6% vs 9.3%; P = .628); all patients recovered without any sequelae. The postoperative pain scores were lower, and fewer rescue analgesics were used in the spinal anesthesia group than in the general anesthesia group. Other maternal and neonatal outcomes were not different between the 2 groups. CONCLUSIONS Compared with general anesthesia, spinal anesthesia mitigated the maximum arterial blood pressure during cesarean delivery and improved postoperative pain in patients with moyamoya disease.

Abstract
Maternal stroke occurs in around 34 out of every 100,000 deliveries and is responsible for around 5%-12% of all maternal deaths. It is most commonly hemorrhagic, and women are at highest risk for developing pregnancy-related hemorrhage during the early postpartum period through 6 weeks following the delivery. The most common causes of hemorrhagic stroke in pregnant patients are arteriovenous malformations and cerebral aneurysms. Management is similar to that for acute hemorrhagic stroke in the nonpregnant population with standard use of computed tomography and judicious utilization of intracranial vessel imaging and contrast. The optimal delivery method is evaluated on a case-by-case basis, and cesarean delivery is not always required. As most current studies are limited by retrospective design, relatively small sample sizes, and heterogeneous study term definitions, strong and comprehensive evidence-based guidelines on the management of acute hemorrhagic stroke in pregnant patients are still lacking. In the future, multicenter registries and prospective studies with uniform definitions will help improve management strategies in this complex patient population.

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
BACKGROUND AND AIMS As moyamoya disease in pregnancy is clinically rare, it is poorly understood. We therefore analyzed our experiences of moyamoya disease pregnancies and deliveries over three decades. METHODS The clinical data of 78 pregnancies and 77 deliveries among 62 moyamoya disease cases at Tokyo Medical and Dental University Hospital from 1991 to 2019 were retrospectively reviewed. RESULTS There were six, 17 and 55 pregnancies in the first, second, and last decades, respectively. The mean patient age at delivery was 29.3 ± 5.0 years. The primary symptoms of moyamoya disease at diagnosis were ischemia in 50 cases (64.1%) and intracranial hemorrhage in eight cases (10.2%). Cesarean section was performed in 75 cases (96.2%). Fifteen pregnancies (19.2%) developed hypertensive disorders of pregnancy; of these, 13 (86.7%) developed hypertensive disorders of pregnancy after 34 weeks of gestation and 9 (60%) required emergency cesarean section because of a sudden increase in blood pressure. Four (5.1%) women experienced renal artery stenosis complications and three of them developed hypertension during pregnancy. Two (2.6%) experienced cerebral infarctions several days after delivery, both of whom had no subsequent aftereffects. No cases of hemorrhagic stroke were reported in the peripartum period. CONCLUSIONS To date, this is the largest single-center analysis. It showed the number of moyamoya disease pregnancies has risen rapidly over the last decade. The hypertensive disorders of pregnancy and emergency cesarean section rates were high among moyamoya disease patients. Minor ischemic stroke was observed, but its prevalence was low. Therefore, pregnant women with moyamoya disease should be managed with the understanding that hypertensive disorders of pregnancy is a common complication.

Abstract
Ischemic stroke (IS) and hemorrhagic stroke (HS) can be devastating complications during pregnancy and the puerperium that are thought to occur in approximately 30 in 100,000 pregnancies. In high-risk groups, such as women with preeclampsia, the incidence of both stroke subtypes, combined, is up to 6-fold higher than in pregnant women without these disorders. IS or HS may present in young women with atypical symptoms including headache, seizure, extremity weakness, dizziness, nausea, behavioral changes, and visual symptoms. Obstetric anesthesiologists who recognize these signs and symptoms of pregnancy-related stroke are well positioned to facilitate timely care. Acute stroke of any type is an emergency that should prompt immediate coordination of care between obstetric anesthesiologists, stroke neurologists, high-risk obstetricians, nurses, and neonatologists. Historically, guidelines have not addressed the unique situation of maternal stroke, and pregnant women have been excluded from the large stroke trials. More recently, several publications and professional societies have highlighted that pregnant women suspected of having IS or HS should be evaluated for the same therapies as nonpregnant women. Vaginal delivery is generally preferred unless there are obstetric indications for cesarean delivery. Neuraxial analgesia and anesthesia are frequently safer than general anesthesia for cesarean delivery in the patient with a recent stroke. Potential exceptions include therapeutic anticoagulation or intracranial hypertension with risk of herniation. General anesthesia may be appropriate when cesarean delivery will be combined with intracranial neurosurgery.

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
Anesthesia for Cesarean section could be challenging due to the physiological changes during pregnancy, but it can be more complicated if associated with sickle cell disease and moyamoya disease. The moyamoya syndrome is nothing but sickle cell disease complicated by cerebral vasculopathy. Incidence of moyamoya disease in the USA is 0.086/100,000 people. We report a case of a pregnant woman with sickle cell disease and moyamoya syndrome, who underwent a successful spinal epidural for primary cesarean section, with careful monitoring of blood pressure.

Abstract
Postpartum seizures secondary to subarachnoid haemorrhage (SAH) are rare. The incidence of pregnancy-related SAH is increasing and is highest during the delivery and postpartum periods. While there have been cases in the literature of SAH occurring postpartum, very few are associated with Moyamoya disease. We present a rare case of a young woman diagnosed with Moyamoya disease following immediate postpartum seizures secondary to a SAH. She was medically managed and discharged without any neurological deficits. This case highlights how seizures and SAH may develop in the immediate postpartum period in an otherwise healthy young woman.

Abstract
There are no practice guidelines for the treatment of moyamoya disease in pregnant women. The need for such guidelines, however, is evidenced by the numerous case reports, case series, and systematic reviews in the literature highlighting an at-risk period for female moyamoya patients of childbearing age. Here the authors review and interpret the existing literature as it applies to their index patient and expand the literature in support of treating select patients during pregnancy. The authors describe what is to their knowledge the first case reported in the literature of a patient successfully treated with indirect surgical revascularization during the first trimester, who went on to deliver a healthy term baby without complications.

Abstract
OBJECTIVE Moyamoya disease (MMD) disproportionately affects young to middle-aged women. The main treatment for this challenging disease is cerebral bypass surgery. Vascular neurosurgeons often need to counsel women regarding pregnancy following bypass for MMD, but there is a paucity of data. The authors set out to examine neurological and obstetric outcomes in an extensive cohort of MMD patients who had pregnancies following cerebral revascularization at the Stanford Medical Center. METHODS The authors identified all patients at their institution who underwent cerebral bypass for MMD from 1990 through 2018 and who later became pregnant. Some of these patients also had pregnancies prior to undergoing bypass surgery, and the authors examined these pregnancies as well. They performed a chart review and brief telephone survey to identify obstetric complications, transient ischemic attacks (TIAs), and strokes. Neurological and obstetric outcomes were compared to published rates. They also compared pre- and post-bypass pregnancy complication rates using logistic regression techniques. RESULTS There were 71 pregnancies among 56 women whose mean age was 30.5 years. Among 59 post-bypass pregnancies, there were 5 (8%) perinatal TIAs. There were no MRI-confirmed strokes or strokes with residual deficits. Among 12 pre-bypass pregnancies, there were 3 (25%) TIAs and 2 (17%) MRI-confirmed strokes. There were no hemorrhagic complications in either group. In the generalized estimating equations analysis, performing cerebral revascularization prior to pregnancy versus after pregnancy was associated with lower odds of perinatal stroke or TIA (OR 0.15, p = 0.0061). Nine pregnancies (13%) were complicated by preeclampsia, and there was one (1%) instance of eclampsia. The overall rate of cesarean delivery was 39%. There were 2 miscarriages, both occurring in the first trimester. There were no maternal deaths. CONCLUSIONS The authors present neurological and obstetric outcomes data in a large cohort of MMD patients. These data indicate that post-bypass pregnancy is accompanied by low complication rates. There were no ischemic or hemorrhagic strokes among post-bypass pregnant MMD patients. The rate of obstetric complications was low overall. The authors recommend close collaboration between the vascular neurosurgeon and the obstetrician regarding medical management, including blood pressure goals and continuation of low-dose aspirin.
