Radiol Case Rep 2024; 19:2724-2728. [PMID: 38680741 PMCID: PMC11047181 DOI: 10.1016/j.radcr.2024.03.009] [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: 01/21/2024] [Revised: 03/01/2024] [Accepted: 03/06/2024] [Indexed: 05/01/2024] Open
Abstract
Vein of Galen malformation (VGM) is a rare congenital, uncommon intracerebral vascular anomaly rarely complicated with the development of brain abscess as secondary to primary infection or after endovascular treatment. We report a very rare finding of a vein of Galen aneurysm associated with a large brain abscess at the time of diagnosis. A 12-year-old boy with a high-grade fever, severe headache, and recurrent episodes of convulsions came into the radiology department of Kassala Advanced Diagnostic Center. On a Siemens 16-slice scanner, brain non-contrast enhanced computed tomography (NECT) and contrast enhanced CT (CECT) was used to determine the source of the acute headache and convulsions which revealed a right frontal peripherally enhancing cystic lesion measuring 5.7 × 4.7 × 5.3 cm2 surrounded by massive vasogenic edema causing mass effect with midline shift to the left side by 1.5 cm suggestive of brain abscess. There is evidence of another avidly enhancing lesion seen within the third ventricle continuous with a straight sinus surrounded by extensive vascular loops consistent with an aneurysm of the vein of Galen, it was causing compression of the cerebral aqueduct with upstream mild hydrocephalus with dilated both lateral ventricles. Late presentation, diagnosis, and treatment also lead to an increase in the morbidities and mortalities of such case conditions. Urgent intervention should be considered for better outcomes.

Eur J Obstet Gynecol Reprod Biol X 2024; 22:100306. [PMID: 38846579 PMCID: PMC11153931 DOI: 10.1016/j.eurox.2024.100306] [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: 02/01/2024] [Accepted: 03/25/2024] [Indexed: 06/09/2024] Open
Abstract
Vein of Galen aneurysmal malformation (VGAM) is a rare vascular anomaly originating during embryonic development, specifically between the 6th and 11th weeks of gestation. This malformation results from abnormal arteriovenous connections between primitive choroidal arteries and the median prosencephalic vein (MPV) of Markowski. Typically, the MPV regresses by the 11th week, but in VGAM, this regression is hindered, leading to persistent abnormal flow and the formation of arteriovenous shunts. We present a case of successful prenatal detection, as well as a comprehensive literature review that summarizes current knowledge, emphasizes the importance of prenatal detection, detailed imaging techniques, understanding clinical presentations, and outlines treatment options. Prenatal detection, crucial for early intervention, has become feasible through ultrasonography and MRI. Fetal MRI has emerged as the gold standard, offering detailed insights into arterial feeders, nidus presence, fistula position, venous drainage, and potential complications. The clinical presentation of VGAM varies with age, and neonates diagnosed in utero may exhibit signs of high-output cardiac failure. Early detection is critical for timely intervention, as untreated VGAMs often result in high mortality rates. Prognosis depends on the severity of heart failure, the number of arteriovenous shunts, and the presence of accompanying fetal abnormalities. Various imaging modalities, including CT angiography and digital subtraction angiography (DSA), aid in the assessment and treatment of VGAM. DSA remains the gold standard for evaluating angioarchitecture and guiding endovascular interventions. The optimal treatment for VGAM is transarterial embolization, offering significant improvements in prognosis. Surgical interventions are limited due to high morbidity and mortality. Management decisions should consider the balance between minimizing neurological damage and achieving maximum embolization effectiveness.

Abstract
BACKGROUND AND PURPOSE Vein of Galen malformation is a rare congenital cerebrovascular malformation. In affected patients, increased cerebral venous pressure constitutes an important etiologic factor for the development of brain parenchymal damage. The aim of this study was to investigate the potential of serial cerebral venous Doppler measurements to detect and monitor increased cerebral venous pressure. MATERIALS AND METHODS This was a retrospective monocentric analysis of ultrasound examinations within the first 9 months of life in patients with vein of Galen malformation admitted at <28 days of life. Categorization of perfusion waveforms in the superficial cerebral sinus and veins into 6 patterns was based on antero- and retrograde flow components. We performed an analysis of flow profiles across time and correlation with disease severity, clinical interventions, and congestion damage on cerebral MR imaging. RESULTS The study included 44 Doppler ultrasound examinations of the superior sagittal sinus and 36 examinations of the cortical veins from 7 patients. Doppler flow profiles before interventional therapy correlated with disease severity determined by the Bicêtre Neonatal Evaluation Score (Spearman ρ = -0.97, P = < .001). At this time, 4 of 7 patients (57.1%) showed a retrograde flow component in the superior sagittal sinus, whereas after embolization, none of the 6 treated patients presented with a retrograde flow component. Only patients with a high retrograde flow component (equal or more than one-third retrograde flow, n = 2) showed severe venous congestion damage on cerebral MR imaging. CONCLUSIONS Flow profiles in the superficial cerebral sinus and veins appear to be a useful tool to noninvasively detect and monitor cerebral venous congestion in vein of Galen malformation.

Abstract
BACKGROUND Since the advent of endovascular treatment, the long-term prognosis of vein of Galen malformation (VOGM) has markedly improved; however, the nature of research leading to this point is unclear. The objective of this study was to define the composition of VOGM research to date, by means of a bibliometric analysis of the 100 most cited VOGM articles. METHODS An electronic search of Elsevier's Scopus database was performed to identify the 100 most cited articles on VOGM screened against predetermined criteria. Data were then compared. RESULTS The 100 most cited VOGM articles were published between 1974 and 2017 in 38 unique journals and originated from 16 unique countries. Mean citation count and rate were 59.4 citations and 2.9 citations/year, respectively. The USA (n = 42); Hôpital de Bicêtre, France (n = 15); and Dr. Pierre Lasjaunias (n = 16) were the largest individual country, institutional, and author contributors. Compared to the older articles (published < 2000), key differences for newer articles were statistically higher citation rates (P < 0.01), more authors (P < 0.01), higher proportion of endovascular treatment descriptions (P = 0.01), and more originating from Asia Pacific (P < 0.01). CONCLUSIONS From the 100 most cited VOGM articles to date, there has been a noticeable shift from diagnosing VOGM based on the foundational work by Dr. Lasjaunias to understanding how we can model clinical outcomes now that endovascular treatment has become the standard of care. Significant shifts in prognosis are pending, and the current bibliometric data implicate we are on the precipice of more recent works making an impact in the near future.

Abstract
The range of intracranial venous anomalies in children differs from that in adults. As a commonly encountered highly morbid disease, sinovenous thrombosis has been discussed extensively in the literature, and the associated imaging considerations are similar in pediatric and adult patients. The authors shift the focus to less frequently discussed cerebral venous diseases in pediatric patients. First, the practical embryology pertinent to malformations, syndromes, and variants such as vein of Galen aneurysmal malformation, Sturge-Weber syndrome, and developmental venous anomalies are discussed. Second, anatomic considerations that are applicable to neuroimaging in pediatric patients with cerebral venous anomalies are reviewed. In the discussion of anatomy, special attention is given to the medullary venous system that serves the cerebral white matter, superficial cortical veins (tributaries of the dural venous sinuses), and bridging veins, which carry blood from the superficial cortical veins through the potential subdural space into the dural venous sinuses. Third, the selection of imaging modalities (US, CT and CT venography, and MRI) is addressed, and various MR venographic pulse sequences (time-of-flight, phase-contrast, and contrast-enhanced sequences) are compared. Finally, a broad variety of congenital and acquired superficial and deep venous diseases in children are reviewed, with emphasis on less frequently discussed entities involving the medullary (eg, deep medullary venous engorgement and thrombosis, periventricular hemorrhagic venous infarction due to germinal matrix hemorrhage), cortical (eg, cortical venous thrombosis), and bridging (eg, acute and chronic manifestations of injury in abusive head trauma) veins, as well as the deep veins and dural venous sinuses (eg, varix). © RSNA, 2023 Quiz questions for this article are available through the Online Learning Center.

Abstract
OBJECTIVES To report the outcome of fetuses with a prenatal diagnosis of Vein of Galen (VOG) malformation. METHODS PubMed and Embase databases were searched. Random effect meta-analysis of proportions was used to analyze the data. The outcomes explored were prenatal ultrasound findings, mortality, preterm birth (PTB), abnormal neurological outcome, associated findings detected at post-natal brain imaging, need for anticonvulsant therapy, and the rate of children free from neurological impairment. Random effect meta-analysis of proportions were used to analyze the data. RESULTS Eleven studies (226 fetuses with a prenatal diagnosis of VOG malformation) were included. All cases were detected during the third trimester of pregnancy. Ventriculomegaly was detected in 31.8% (95% CI 27.6-47.7), cardiomegaly or other ultrasound signs of cardiac compromise in 23.1% (95% CI 14.9-32.5) and hydrops in 7.3% (95% CI 2.8-13.6) of cases. The incidence of IUD, NND, and PND was 1.5% (95% CI 0.2-4.3), 23.8% (95% CI 16.9-31.4), and 24.5% (95% CI 17.6-32.2), respectively, while 12.6% (95% CI 6.0-21.2) of pregnancies were complicated by PTB. Abnormal neurodevelopmental outcome was observed in 36.7% (95% CI 27.9-39.7) of cases, while 60.5% (95% CI 17.0-82.0) of children had abnormal findings on post-natal imaging and only 29.7% (95% CI 23.3-36.5) were free from neurological impairment after birth, although there was a wide heterogeneity in the time at follow-up between the included studies. CONCLUSION VOG malformation diagnoses during fetal life is associated with a high incidence of brain damage, cardiac compromise, and abnormal neurodevelopmental outcome after birth.

Abstract
We present a case of a pregnant patient with an unrepaired vein of Galen malformation (VGAM) and left ventricular (LV) dilation. Patients with VGAM lesions typically present during childhood with cardiac failure or developmental delay prompting embolization. Therefore, it is highly unusual for an adult to present with an unrepaired lesion.1 It poses challenges for obstetric and anesthetic management during pregnancy and delivery to reduce the risk of heart failure, arrhythmia, and intracranial hemorrhage. Our patient safely delivered a term neonate by cesarean delivery with neuraxial analgesia at a Level IV Maternal Care Center.

Abstract
Introduction Understanding outcomes after Vein of Galen malformation (VOGM) embolization has been limited by small sample size in reported series and predominantly single center studies. To address these limitations, we perform an individual-participant meta-analysis (IPMA) to identify risk factors associated with all-cause mortality and clinical outcome after VOGM endovascular embolization. Methods We performed a systematic review and IPMA of VOGM endovascular outcomes according to PRISMA guidelines. Individual patient characteristics including demographic, intra/post-operative adverse events, treatment efficacy (partial or complete occlusion), and clinical outcome were collected. Mixed-effects logistic regression with random effects modeling and Bonferroni correction was used (p ≤ 0.003 threshold for statistical significance). The primary and secondary outcomes were all-cause mortality and poor clinical outcome (moderate/severe developmental delay or permanent disabling injury), respectively. Data are expressed as (mean ± standard deviation (SD)) or (odds ratio (OR), 95% confidence interval (CI), I 2, p-value). Results Thirty-five studies totaling 307 participants quantifying outcomes after endovascular embolization for VOGM were included. Follow up time was 42 (±57) months. Our analysis contained 42% neonates (<1 month) at first embolization, 45% infants (1 month ≤2 years), and 13% children (>2 years). Complete occlusion was reported in 48% of participants. Overall all-cause mortality was 16%. Overall, good clinical outcome was achieved in 68% of participants. First embolization as a neonate [OR = 6.93; 95% CI (1.99-24.08); I 2 < 0.01; p < 0.001] and incomplete embolization [OR = 10.87; 95% CI (1.86-63.55); I 2 < 0.01; p < 0.001] were associated with mortality. First embolization as a neonate [OR = 3.24; 95% CI (1.47-7.15); I 2 < 0.01; p < 0.001], incomplete embolization [OR = 5.26; 95% CI (2.06-13.43); I 2 < 0.01; p < 0.001], and heart failure at presentation [OR = 3.10; 95% CI (1.03-9.33); I 2 < 0.01; p = 0.002] were associated with poor clinical outcomes. Sex, angioarchitecture of lesion, embolization approach (transvenous vs. transarterial), and single or multistage embolization were not associated with mortality or clinical outcome. Conclusions We identify incomplete VOGM embolization independently associated with mortality and poor clinical outcome. While this study provides the highest level of evidence for VOGM embolization to date, prospective multicenter studies are needed to understand the optimal treatment strategies, outcomes, and natural history after VOGM embolization.

Abstract
Vein of Galen aneurysmal malformation (VGAM) is a severe rare vascular anomaly whose prognosis depends on cerebral and cardiac consequences that can be hard to diagnose, let alone predict in utero. We performed an updated review to summarize current research on the genetics, ultrasound and MRI of VGAM that could help in the diagnosis and management of VGAM. Prenatal diagnosis of VGAM has greatly improved in recent years. Ultrasound allows in utero detection of VGAM in most cases now and is the best exam for prenatal cardiac evaluation. Tricuspid insufficiency is the only cardiac feature associated with poor prognosis. Cardiomegaly may indicate a risk of cardiac failure at birth and should prompt discussion of birth in a specialized facility. Ultrasound can identify constituted cerebral lesions, but MRI diagnoses early signs of cerebral hemodynamic changes, notably through the detection of pseudo-feeders. Genetic exploration should be proposed after VGAM diagnosis. Ultrasound and MRI are essential complementary tools for the diagnosis of VGAM, but also for prognostic evaluation, and provide information for the counseling of parents and optimal management of the pregnancy.

Abstract
INTRODUCTION Vein of Galen malformations (VOGMs) represent a rare pathologic entity with often catastrophic natural history. The advances in endovascular treatment in recent years have allowed for a paradigm shift in the treatment and outcome of these high-flow shunts, even though their pathogenetic mechanisms and evolution remain in part obscure. AREAS COVERED The overall management of VOGMs requires a tailored case-to-case approach, starting with in utero detection and reserving endovascular treatment for indicated cases. Lately, the advances in translational research with whole-genome sequencing and the coupling with cellular-level hemodynamics attempt to shed more light in the pathogenesis and evolution of these lesions. At the same time the advances in endovascular techniques allow for more safety and tailored technical strategy planning. Furthermore, the advances in MRI techniques allow a better understanding of their vascular anatomy. In view of these recent advances and by performing a PUBMED literature review of the last 15 years, we attempt a review of the evolutions in the imaging, management, endovascular treatment and understanding of underlying mechanisms for VOGMs. EXPERT OPINION The progress in the fields detailed in this review appears very promising in better understanding VOGMs and expanding the available therapeutic arsenal.

Abstract
Macrocephaly is commonly encountered in the primary care provider's office. It is defined as an occipitofrontal circumference that is greater than 2 standard deviations above the mean for the child's given age. Macrocephaly is a nonspecific clinical finding that may be benign or require further evaluation. An algorithmic approach is useful for aiding in the clinical decision-making process to determine if further evaluation with neuroimaging is warranted. Abnormal findings may signify a harmful underlying cause, requiring referral to a genetic specialist or neurosurgeon.

Abstract
INTRODUCTION Vein of Galen malformations (VGMs) are complex congenital arteriovenous malformations that generally require serial endovascular treatment sessions to slowly correct the high-flow fistulous connections that cause increased venous pressures and ultimately lead to the classic presentations of heart failure, hydrocephalus, and intracranial hemorrhages. Despite the advances in endovascular technology and embolic materials, the resolution of embolization is often limited to the subjective view of diminished flow on angiograms. CASE REPORT An 8-month-old patient with a VGM developed clinical signs of heart failure and growing head circumference with ventriculomegaly. The patient was treated endovascularly with a transvenous approach for coil embolization while undergoing continuous monitoring of the post-malformation venous pressures. The arterial and venous systolic blood pressures (SBP) were collected at serial time points and used to measure estimated 95% confidence interval bounds for arteriovenous SBP gradients and determine when sufficient coil embolization and flow reduction was thought to be achieved. CONCLUSION The transvenous pressure monitoring demonstrated progressively increasing pressure gradients between the arterial and venous systems that correlated with the degree of flow reduction on angiographic runs. The patient underwent successful coil embolization of the VGM and had improvement of heart failure and ventricular size in follow-up at 8-month post-op. This provides a novel technique to introduce an objective measurement that can guide the embolization of a VGM.

Abstract
Hemorrhagic cerebrovascular disease in the pediatric population can have devastating and long-term effects. Progress in the fields of genetics, neuroimaging, pharmacology, and surgical techniques has led to improved diagnosis and management of pediatric cerebrovascular diseases. In this review we discuss the current etiologies and medical and surgical treatments of hemorrhagic cerebrovascular pathology affecting infants and children. A special emphasis is placed on neuroendovascular treatment options. Increased knowledge about this unique pathology and the medical and therapeutic options will empower practitioners to more quickly and accurately identify and accurately treat hemorrhagic diseases in the pediatric population.

Abstract
BACKGROUND AND PURPOSE Neonates with vein of Galen malformations are split into 2 cohorts: one needing urgent neonatal embolization, with relatively high mortality and morbidity even with expert care, and a cohort in which embolization can be deferred until infancy, with far better prognosis. We aimed to identify brain MR imaging characteristics obtained from fetal and early neonatal scans that can predict the clinical presentation. MATERIALS AND METHODS Patients with vein of Galen malformations were stratified into a neonatal at-risk cohort if the patient needed urgent neonatal intervention or if neonatal death occurred; or an infantile treatment cohort if they were stable enough not to require treatment until >1 month of age. Twelve vascular MR imaging parameters, measured by 2 independent observers, were systematically correlated with the need for early neonatal intervention and/or neonatal mortality. RESULTS A total of 32 neonatal patients (21 patients in the neonatal at-risk cohort, 11 in the infantile treatment cohort) were identified. Maximal mediolateral diameter (area under the curve = 0.866, P < .001) and cross-sectional area (area under the curve = 0.836, P = .002) at the narrowest point of the straight or falcine sinus were most predictive of clinical evolution into the neonatal at-risk cohort. There were 15 patients who had fetal MRIs (10 in the neonatal at-risk cohort and 5 in the infantile treatment cohort). Here too, maximal mediolateral diameter (area under the curve = 0.980, P = .003) and cross-sectional area (area under the curve = 0.941, P = .007) at the narrowest point of the straight or falcine sinus were highly predictive of the neonatal at-risk cohort. CONCLUSIONS Early neonatal and fetal MR imaging can be readily used for accurate early risk stratification, assisting in directing resources, timing treatment decisions, and identifying appropriate cohorts for novel interventions.

Abstract
The interpretation of cerebral venous pathologies in paediatric practice is challenging as there are several normal anatomical variants, and the pathologies are diverse, involving the venous system through direct and indirect mechanisms. This paper aims to provide a comprehensive review of these entities, as their awareness can avoid potential diagnostic pitfalls. We also propose a practical classification system of paediatric cerebral venous pathologies, which will enable more accurate reporting of the neuroimaging findings, as relevant to the underlying pathogenesis of these conditions. The proposed classification system comprises of the following main groups: arterio-venous shunting-related disorders, primary venous malformations and veno-occlusive disorders. A multimodal imaging approach has been included in the relevant subsections, with a brief overview of the modality-specific pitfalls that can also limit interpretation of the neuroimaging. The article also summarises the current literature and international practices in terms of management options and outcomes in specific disease entities.

Abstract
See Meschia (doi:10.1093/brain/awy066) for a scientific commentary on this article.Vein of Galen aneurysmal malformation is a congenital anomaly of the cerebral vasculature representing 30% of all paediatric vascular malformations. We conducted whole exome sequencing in 19 unrelated patients presenting this malformation and subsequently screened candidate genes in a cohort of 32 additional patients using either targeted exome or Sanger sequencing. In a cohort of 51 patients, we found five affected individuals with heterozygous mutations in EPHB4 including de novo frameshift (p.His191Alafs*32) or inherited deleterious splice or missense mutations predicted to be pathogenic by in silico tools. Knockdown of ephb4 in zebrafish embryos leads to specific anomalies of dorsal cranial vessels including the dorsal longitudinal vein, which is the orthologue of the median prosencephalic vein and the embryonic precursor of the vein of Galen. This model allowed us to investigate EPHB4 loss-of-function mutations in this disease by the ability to rescue the brain vascular defect in knockdown zebrafish co-injected with wild-type, but not truncated EPHB4, mimicking the p.His191Alafs mutation. Our data showed that in both species, loss of function mutations of EPHB4 result in specific and similar brain vascular development anomalies. Recently, EPHB4 germline mutations have been reported in non-immune hydrops fetalis and in cutaneous capillary malformation-arteriovenous malformation. Here, we show that EPHB4 mutations are also responsible for vein of Galen aneurysmal malformation, indicating that heterozygous germline mutations of EPHB4 result in a large clinical spectrum. The identification of EPHB4 pathogenic mutations in patients presenting capillary malformation or vein of Galen aneurysmal malformation should lead to careful follow-up of pregnancy of carriers for early detection of anomaly of the cerebral vasculature in order to propose optimal neonatal care. Endovascular embolization indeed greatly improved the prognosis of patients.

Abstract
BACKGROUND AND PURPOSE The vein of Galen aneurysmal malformation (VGAM) is a rare congenital vascular malformation with a higher morbidity and mortality, especially in neonates. Ultrasound, CT and MR are usually used in diagnosis and treatment monitoring of these disorders. In this current study, we aim to examine utility of SWI in evaluation of treatment response in infants with VGAM. MATERIALS AND METHODS We performed a retrospective chart analysis of children with VGAM in our institution between January 2008 and December 2016. Inclusion criteria included; confirmed VGAM on DSA; available SWI sequence at baseline and at follow up after at least a single embolization session; age at initial MR of 18 years or younger. Signal intensity and Angioarchitecture of VGAM and cerebral veins on SWI, as well as hydrocephalus and clinical outcome were evaluated. RESULTS Of 11 patients identified with VGAM in our institution, 5 children (3 males and 2 females) satisfied the inclusion criteria. The average age at initial MR was 29 days (range 1-120). Fourteen MRI were available for review. All children had VGAM of mural type. Intramedullary veins were dilated and SWI-hypointense in all children, while subependymal and sulcal veins were dilated and SWI-hypointense in 4 patients on initial MRI. On the first available follow up MRI, cerebral veins have mostly normalized in 4 children and remained mostly dilated and SWI-hypointense in 1 child; even after complete treatment of the VGAM. CONCLUSION Our preliminary findings show that SWI seems to offer a beneficial non-invasive tool in evaluating passive venous congestion patterns in pediatric patients with VGAM. It remains to be determined in larger studies, the clinical significance of these SWI changes.

Abstract
Vein of Galen malformations (VOGMs) are rare developmental cerebrovascular lesions characterized by fistulas between the choroidal circulation and the median prosencephalic vein. Although the treatment of VOGMs has greatly benefited from advances in endovascular therapy, including technical innovation in interventional neuroradiology, many patients are recalcitrant to procedural intervention or lack accessibility to specialized care centers, highlighting the need for improved screening, diagnostics, and therapeutics. A fundamental obstacle to identifying novel targets is the limited understanding of VOGM molecular pathophysiology, including its human genetics, and the lack of an adequate VOGM animal model. Herein, the known human mutations associated with VOGMs are reviewed to provide a framework for future gene discovery. Gene mutations have been identified in 2 Mendelian syndromes of which VOGM is an infrequent but associated phenotype: capillary malformation-arteriovenous malformation syndrome ( RASA1) and hereditary hemorrhagic telangiectasia ( ENG and ACVRL1). However, these mutations probably represent only a small fraction of all VOGM cases. Traditional genetic approaches have been limited in their ability to identify additional causative genes for VOGM because kindreds are rare, limited in patient number, and/or seem to have sporadic inheritance patterns, attributable in part to incomplete penetrance and phenotypic variability. The authors hypothesize that the apparent sporadic occurrence of VOGM may frequently be attributable to de novo mutation or incomplete penetrance of rare transmitted variants. Collaboration among treating physicians, patients' families, and investigators using next-generation sequencing could lead to the discovery of novel genes for VOGM. This could improve the understanding of normal vascular biology, elucidate the pathogenesis of VOGM and possibly other more common arteriovenous malformation subtypes, and pave the way for advances in the diagnosis and treatment of patients with VOGM.

Abstract
Purpose Adjuvant coils may offer advantages in flow control during glue embolization of high flow vein of Galen aneurysmal malformation (VGAM) patients but involves specific issues such as feasibility, durability and coil mass effect. The purpose of this study is to assess the outcome of adjuvant coils in addition to transarterial glue embolization for treatment of these patients. Materials and Methods Five pediatric VGAM patients (age range; 11 weeks to 2 yrs 2 mos) with high flow fistulous angioarchitecture were treated with adjuvant coils 1) in the distal feeding artery and/or 2) in the vein of Galen followed by glue embolization of the shunt. The angiographic / clinical outcomes were assessed. Results Adjuvant coils were deployed in the distal feeding artery (n=3), vein of Galen pouch plus distal feeding artery (n=2). Additional transarterial glue embolization of the fistulae was successfully performed (n=4). Complete occlusion was achieved with coils in one case. Complete occlusion was achieved for all mural type cases (n=4). Residual feeders remained in a case of choroidal type of VGAM. No complications were noted related to the treatment. All patients showed normal development on follow up (range: 7.6 to 88.8 mo, mean 49.3 mo). Initial hydrocephalus improved on follow up despite coil mass effect in dilated vein of Galen. Conclusion Adjuvant coils for flow control with glue embolization may be a safe and effective treatment method for VGAM patients with high flow fistulous feeders.

Abstract
Vein of Galen aneurysmal malformation (VGAM) is a rare angiopathy, which most commonly presents in infancy. Although very rare, it is associated with high morbidity and mortality rates. In order to minimize such morbid rates, a prompt diagnosis followed by a timely initiation of management is crucial. Multiple antenatal and postnatal imaging techniques for the diagnosis have been described and discussed in the literature. However, to our knowledge, a comprehensive review exploring such a list of imaging options for VGAM has never been established. We aim to review the diagnostic tools to aid in better understanding of the investigative modalities physicians may choose from when treating patients with a VGAM.

Abstract
BACKGROUND The vein of Galen aneurysmal malformation (VGM) is a rare intracranial arteriovenous fistula with a dramatic manifestation during infancy and 100% mortality without treatment. Therapeutic strategies for VGMs have changed over time as a result of advances in endovascular techniques. We present our experience and multimodality approach within the last 4 decades. METHODS A retrospective analysis and angiographic review were performed of patients with VGM between 1975 and 2016 at our institution. RESULTS Eighteen consecutive patients were identified, including 10 with choroidal and 8 with mural VGMs. In 37 endovascular interventions, a transarterial approach was mostly performed (82.8%). One patient was initially treated surgically and received 2 Gamma Knife treatments after multiple embolizations. The preferred embolization agent was histoacryl for choroidal VGMs and a combination of coils and histoacryl for mural VGMs. Total occlusion was achieved in 87.5% of mural VGMs and 11.1% of choroidal VGMs. Cerebral hemorrhages and infarction occurred only in patients younger than 1 month. At a median follow-up interval of 4.6 years, good outcome was achieved in 53.8% and poor outcome in 46.2%, with an overall mortality of 16.7%. Poor outcome was significantly associated with choroidal-type VGMs, age <1 month at first embolization, and incomplete occlusion. CONCLUSIONS Endovascular embolization using a transarterial approach is the therapy of choice. Gamma Knife radiosurgery can be considered as second-line therapy in a multimodal approach. Whereas treatment within the first month of life is associated with the highest mortality and complications, we did not detect any severe adverse events thereafter.

Abstract
The term vein of Galen aneurysm is related to a group of different vascular anomalies, with one common distinction being the dilatation of the vein of Galen. It represents a rear vascular anomaly, whose incidence is yet unknown, although some authors suggest numbers around 1:25000 deliveries. It accounts for only 1% of all intracranial malformations, but the percentage of this anomaly in pediatric populations is up to 30%. In most cases the diagnosis is made postnatal, while antenatal diagnosis, because of the pathophysiology of aneurysm itself, as well as pathophysiology of its possible complications, is made usually during the third trimester, frequently after the 34th week of gestation. The earliest reported diagnosis was made at 25 weeks' gestation. In this case we present 25-year old gravida, pregnancy at 28th week of gestation with aneurysm, and sonographically detected aneurysm of the vein of Galen, that ended with termination of pregnancy.

Abstract
BACKGROUND Outcomes after endovascular embolization of vein of Galen malformations remain relatively poorly described. PURPOSE We performed a systematic review of the literature to determine outcomes and predictors of good outcomes following endovascular treatment of vein of Galen malformations. DATA SOURCES We used Ovid MEDLINE, Ovid Embase, and the Web of Science. STUDY SELECTION Our study consisted of all case series with ≥4 patients receiving endovascular treatment of vein of Galen malformations published through January 2017. DATA ANALYSIS We studied the following outcomes: complete/near-complete occlusion rates, technical complications, perioperative stroke, perioperative hemorrhage, technical mortality, all-cause mortality, poor neurologic outcomes, and good neurologic outcomes. Outcomes were stratified by age-group (neonate, infant, child). A random-effects meta-analysis was performed. DATA SYNTHESIS A total of 27 series with 578 patients were included; 41.9% of patients were neonates, 45.0% of patients were infants, and 13.1% of patients were children. All-cause mortality was 14.0% (95% CI, 8.0%-22.0%). Overall good neurologic outcome rates were 62.0% (95% CI, 57.0%-67.0%). Overall poor neurologic outcome rates were 21.0% (95% CI, 17.0%-26.0%). Neonates were significantly less likely to have good neurologic outcomes than infants (48.0%; 95% CI, 35.0%-62.0% versus 77.0%; 95% CI, 70.0%-84.0%; P < .01). Treatment indications following the Bicêtre neonatal evaluation score resulted in significantly higher rates of good neurologic outcome (P = .04). Patients with congestive heart failure had significantly lower rates of good neurologic outcome (OR, 0.50; 95% CI, 0.28-0.88; P = .01). LIMITATIONS Limitations were selection and publication biases. CONCLUSIONS Patients receiving endovascular embolization of vein of Galen malformations experienced good long-term clinical outcomes in >60% of cases. Appropriate patient selection is key as treatment guided by the Bicêtre neonatal evaluation score was associated with improved neurologic outcomes.

Abstract
Vein of Galen (VG) aneurysmal malformations (VGAMs) are complex vascular lesions. Their etiopathogenesis is extensively debated and remains poorly understood. Strictly speaking, true VGAMs are Galenic pial arteriovenous fistulas. They are believed to arise in utero and are contended to drain either into the true VG or the median prosencephalic vein of Markowski. Several classification systems have been proposed and are widely used. With the advent of endovascular therapy, precise understanding of the angioarchitecture is critical for management and therapeutic decision making. We review clinical presentation and diagnostic imaging findings, discussing angioarchitectural properties as they relate to treatment planning. Clin.

Abstract
PURPOSE AND METHODS Superselective transvenous embolization (TVE) with liquid embolic agents is a new concept in treatment of vein of Galen aneurysmal malformations (VGAM). We performed ten sessions of TVE in VGAM patients with restricted transarterial access. In this paper, we assessed clinical and angiographic outcomes of the proposed treatment and discussed three different TVE techniques with regard to morphology of the shunt and outflow tract. Safety and avoidance-of-complication tips were also discussed. RESULTS Patient age ranged from 4 to 51 months. There were eight patients with choroidal VGAMs, seven of them were successfully treated with Onyx, and in one case, transvenous catheterization failed. In three cases, adjunctive coiling of draining vein was performed. In three cases, normal deep cerebral veins were connected to the outflow part of malformation; they were preserved during embolization in all cases. Six-month follow-up angiography demonstrated angiographic cure in six cases, and partial occlusion in one. There were two patients with mural VGAMs: both were treated with n-BCA. Partial occlusion was achieved in both cases. There was no procedure-related permanent morbidity or mortality. Oculomotor deficit due to quadrigeminal ischemia occurred in one case, and resolved completely after 3 weeks. CONCLUSION TVE with liquid embolic agents is a safe and effective salvage method for VGAMs with restricted transarterial access, previously considered as poor candidates for endovascular treatment.

Abstract
This case report describes the use of the Micro Vascular Plug (MVP) system in a mural-type vein of Galen aneurysmal malformation, resulting in successful occlusion of the cerebrovascular fistula. This result was confirmed with immediate cessation in blood flow and 6-month follow-up angiography. The unique characteristics of the MVP provide potential advantages over current embolic techniques for occlusion of high-flow, fistulous, intracranial vessels such as those seen in the vein of Galen aneurysmal malformation, and may represent a valuable addition to the currently available options.

Abstract
Intracranial pial arteriovenous fistulas, also known as nongalenic fistulas, are rare vascular malformations affecting predominantly the pediatric population. Hydrocephalus is an unusual presentation in which the exact pathophysiology is not fully understood. The aim of treatment in these cases is occlusion of the fistula prior to considering ventricular shunting. Here, the authors describe the hydrodynamic considerations of the paravascular pathway and the resolution of hydrocephalus with endovascular treatment of the fistula.

Abstract
Vein of Galen malformation (VOGM) is a rare congenital vascular malformation caused by the maldevelopment of its embryonic precursor, the median prosencephalic vein of Markowski. VOGM results in neonatal morbidity and mortality, and premature delivery does not improve the outcome. We report a term female neonate in whom a vein of Galen malformation was diagnosed prenatally at 37 wk of gestation during a growth ultrasound and confirmed by fetal magnetic resonance imaging. Signs of cardiac decompensation were evident in the fetus. Multiple interventional radiology embolizations of the feeding vessels were performed successfully on days 7, 10, 12, 14 and 19. A review of the literature on the endovascular management of neonates with these malformations is presented herein.

Abstract
OBJECTIVE The etiology of jugular bulb stenosis (JBS) or occlusion in the context of vein of Galen aneurysmal malformations (VGAMs) is unknown. It can lead to decompensation of a lesion that was previously clinically stable. The aim of this study was to describe the natural history of JBS or occlusion in VGAM and to determine whether there is an association with bony remodeling of the jugular foramina. METHODS The authors identified all cases of JBS greater than 70% bilaterally involving patients seen at The Hospital for Sick Children between January 2007 and June 2014. The foramen diameters were measured on sagittal CT imaging, on a slice passing at the level of the jugular vein. The jugular foramen diameters were also compared to measurements obtained in a matched population of the same age group who had no VGAM and had undergone cerebral CT for a reason other than vascular disease. RESULTS Eight patients (6 male and 2 female) with bilateral JBS were included in this series. The median duration of clinical follow-up was 2.5 years (IQR 1.7-4.2 years). JBS was associated with bony narrowing the jugular foramina in 7 of the 8 patients over time. Between 1 and 2 years of age, patients with a VGAM demonstrated jugular foramen narrowing in comparison with a matched population (p = 0.015). CONCLUSIONS Jugular bulb stenosis or occlusion in VGAM may be associated with narrowing of the jugular foramina. These conditions seem to have a male predominance. If treatment is required, bony narrowing of the jugular foramina should be taken into account when deciding whether angioplasty and stent placement or surgical bypass might be appropriate therapeutic options.

[PMID: 27102351 DOI: 10.1016/j.wneu.2016.04.031] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2016] [Revised: 04/07/2016] [Accepted: 04/08/2016] [Indexed: 01/27/2023]
Abstract
BACKGROUND Vein of Galen aneurysmal malformation (VGAM) is a rare pediatric vascular malformation of the brain. Genetic backgrounds are not well elucidated. We report on a monozygotic twin with VGAM and his endovascular treatment, and the genetic analyses of the twins and their parents. CASE DESCRIPTION In a monochorionic, diamniotic pregnancy of a 28-year-old healthy woman, monozygotic twins were born by emergency caesarian section because of fetal distress of the smaller twin at 25 weeks' and 4 days' gestation. Although a postnatal cranial ultrasound failed to detect VGAM in the smaller twin, mild heart failure persisted. A brain magnetic resonance (MR) examination of this twin on day 82 revealed choroidal VGAM. The twin was treated successfully by two sessions of embolization at 6 and 8 months of age. An MR examination at 1 year showed minimal residual arteriovenous shunts. He developed normally similar to the normal co-twin, with a follow-up period of 1 year and 6 months. As for the affected twin, no germline mutation or copy number variations were identified in ENG, ALK1, SMAD4, BMPR2, PTEN, RASA1, KRIT1, Marcavernin, or PDCD10 through whole-exome sequencing (WES). CONCLUSION We have reported a rare combination of a monozygotic twin and VGAM and the successful endovascular treatment. Phenotypic discordance in monozygotic twins established early in embryogenesis could be attributable to environmental or epigenetic factors.

Abstract
BackgroundVein of Galen aneurysmal malformations (VGAMs) are congenital disorders that may require emergency treatment and some may cause sudden death before medical attention is provided. Some patients also have a spontaneous thrombosis.ObjectiveTo understand the natural progression of VGAMs through a systematic literature review.MethodsWe examined PubMed to identify studies published between July 1973 and March 2015. We determined the proportion of patients with VGAM who died before receiving medical attention, who received emergency treatment, or had a spontaneous thrombosis. We pooled estimates of proportions with corresponding 95% CIs calculated using the raw (ie, untransformed) proportions.ResultsThe 31 studies obtained described the outcome of 754 patients with VGAM. The probability of sudden death risk was 4% (95% CI 1% to 7%; I2=51.6%); of an emergency operation was 46% (95% CI 34% to 58%; I2=93.2%); and of spontaneous thromboses 1% (95% CI 0% to 2%; I2=0%) of cases. Differences between age and clinical outcomes of patients with spontaneous thromboses were significant according to the rank test (Mann–Whitney U test, Z=−2.398, p=0.016), both having a linear correlation (χ2 test, p=0.022).ConclusionsOver time, the rate of preoperative sudden death in patients with VGAM gradually declined and the rate of emergency operations gradually increased. The outcome of patients with early spontaneous thromboses was good. Our study provides a definitive description of the natural progression of VGAMs and the need for urgent medical attention.

Decreased Superior Sagittal Sinus Diameter and Jugular Bulb Narrowing Are Associated with Poor Clinical Outcome in Vein of Galen Arteriovenous Malformation. AJNR Am J Neuroradiol 2016; 37:1354-8.

Abstract
BACKGROUND AND PURPOSE Few clinical and imaging findings are known to be associated with poor outcome in neonates and infants with vein of Galen arteriovenous malformations. In the present consecutive series of 35 patients, we evaluated both the diameter of the superior sagittal sinus at onset and the diameter of the jugular bulb on follow-up as potential factors related to poor outcome. MATERIALS AND METHODS Thirty-five consecutive neonates and infants who were prospectively collected in a single-center data base were included in this review. Outcome was assessed by using the Bicêtre Outcome Score. Both the absolute diameter of the superior sagittal sinus and its ratio to the biparietal diameter were measured at onset, compared with age-matched controls, and correlated to patient outcome. RESULTS The diameter of the superior sagittal sinus at onset and its ratio to the biparietal diameter were significantly smaller in the vein of Galen arteriovenous malformation population compared with the matched population (P = .0001) and were correlated significantly with a risk of poor clinical outcome (P = .008). Development of jugular bulb narrowing was also related to poor clinical outcome (P < .0001). CONCLUSIONS Decreased superior sagittal sinus diameter may reflect a decrease of cerebral blood flow due to cerebral arterial steal and intracranial hydrovenous disorders. This finding may be considered cerebral blood flow deterioration and thus taken into consideration in the management decisions for patients with vein of Galen arteriovenous malformations. Likewise, our data suggest that progressive jugular bulb narrowing may indicate earlier intervention to prevent severe narrowing.

Abstract
BACKGROUND AND PURPOSE Vein of Galen aneurysmal malformation (VGAM) is a rare developmental intracranial vascular malformation. We analyzed the clinical presentations, imaging findings, angioarchitecture, management options, and outcome in a demographically heterogeneous set of VGAM patients. METHODS We retrospectively analyzed cases of VGAM from our departmental archive collected between 1988 and January 2015. Demographic, clinical, therapeutic, and follow-up details were obtained for each patient from the available records. RESULTS We identified 36 patients with VGAM including 6 neonates, 18 infants, 7 children aged 2-10 years, and 5 adults. Macrocrania was the commonest presenting feature. Type of fistulae was mural in 14 and choroidal in 18 patients while 4 had a thrombosed sac at presentation. In 3 cases the dilated venous sac had connection with the deep venous system. Bilateral jugular atresia and stenosis were seen in 9 and 6 patients, respectively. Giant venous sac (>4 cm) was significantly correlated with mural type (p=0.0001). Dural arterial recruitment was seen in 4 patients including 3 adults. Among the 23 patients treated by endovascular means, 14 had a good outcome, 5 had a poor outcome, and 4 died. A significant correlation was noted between jugular atresia and poor outcome (p=0.003). CONCLUSIONS We encountered a wide range of demographic, clinical, and angiographic features in VGAM. Mural type malformations were associated with giant venous sacs. Good outcome after embolization was seen in selected neonates and in most of the infants, children, and adults. Jugular atresia was significantly associated with poor outcome.

Abstract
Fetal magnetic resonance imaging (MRI) serves a dual role in the prenatal diagnostic work up of a vein of Galen aneurysmal malformation (VGAM). First, it may confirm the prenatal ultrasound findings and secondly it may identify prognostically important secondary complications of the VGAM. Progressive heart failure with development of fetal hydrops and hemispheric white matter injuries are associated with a poor outcome in children with a VGAM. We present the prenatal findings using both ultrasound and MRI of a fetus with VGAM including bilateral injury of the cerebral hemispheres, severe dilatation of the jugular veins, cardiomegaly, and hydrops fetalis. The neonate died within 30 minutes after delivery. Moreover, fetal MRI revealed complete placenta praevia, uterine fibroids, and wrapping of the umbilical cord around the fetal neck. This additional information is unrelated to the fetal pathology, but could have been of importance to plan the delivery.

Abstract
OBJECT There have been many multidisciplinary approaches to the treatment of vein of Galen malformations. Endovascular embolization is the first option for treatment. However, the effects of the treatment remain controversial. The aim of this study is to assess the efficacy and safety of endovascular embolization to treat patients with vein of Galen malformations. METHODS This paper includes a retrospective analysis of a sample of 667 patients who underwent endovascular embolization to treat vein of Galen malformations. The data were obtained through a literature search of PubMed databases. The authors also evaluate the efficacy and safety of the treatment. Mortality within the follow-up period is analyzed. Pooled estimates of proportions with corresponding 95% CIs were calculated using raw (i.e., untransformed) proportions (PRAW). RESULTS In the 34 studies evaluated, neonates accounted for 44% of the sample (95% CI 31%-57%; I(2) = 92.5%), infants accounted for 41% (95% CI 30%-51%; I(2) = 83.3%), and children and adults accounted for 12% (95% CI 7%-16%; I(2) = 52.9%). The meta-analysis revealed that complete occlusion was performed in 57% (95% CI 48%-65%; I(2) = 68.2%) of cases, with partial occlusion in 43% (95% CI 34%-51%; I(2) = 70.7%). The pooled proportion of patients showing a good outcome was 68% (95% CI 61%-76%; I(2) = 77.8%), while 31% showed a poor outcome (95% CI 24%-38%; I(2) = 75.6%). The proportional meta-analysis showed that postembolization mortality and complications were reported in 10% (95% CI 8%-12%; I(2) = 42.8%) and 37% (95% CI 29%-45%; I(2) = 79.1%), respectively. Complications included cerebral hemorrhage, cerebral ischemia, hydrocephalus, leg ischemia, and vessel perforation. CONCLUSIONS The successful treatment of vein of Galen malformations remains a complex therapeutic challenge. The authors' analysis of clinical history and research literature suggests that vein of Galen malformations treated with endovascular embolization can result in an acceptable mortality rate, complications, and good clinical outcome. Future large-scale, multicenter, randomized trials are necessary to confirm these findings.

Abstract
PURPOSE Vein of Galen malformations are rare and are usually detected in utero using ultrasonography. No definite genetic predisposition has been described in the literature. We present a case with two successive pregnancies complicated by vein of Galen malformations, which were assessed using fetal MRI. The putative role of genetic mutations is also discussed. METHODS A 30-year-old primigravida presented in the third trimester with a fetus diagnosed with vein of Galen malformation on sonography. MRI and MR angiography were performed for further assessment. The subsequent pregnancy was again complicated by vein of Galen malformation. In addition to MRI, genetic analysis was carried out on both fetuses and on the parents. RESULTS MR angiography revealed that both fetuses suffered from the choroidal sub-type of vein of Galen malformation, with multiple arterial feeders fistulating onto a midline venous pouch. The visualised anatomy obtained was far superior than on sonography and allowed categorisation of vein of Galen malformation sub-type. Genetic analysis on the mother and both fetuses showed variant RASA1 gene mutation. CONCLUSIONS This case demonstrates that fetal MRI is a powerful tool in the investigation of in utero neurovascular malformations. A genetic mutation was identified, but this was of uncertain significance.

Abstract
Cognitive regression is a well-described presentation of vein of Galen aneurysmal malformations (VGAMs) in childhood. However, it remains unclear whether successful treatment of the malformation can reverse cognitive regression. Here, the authors present the case of a 5-year-old girl with a VGAM that was treated with staged endovascular embolization procedures. Comprehensive neurocognitive assessments were completed before intervention and approximately 6 years after initial presentation. There were significant age-matched improvements in this child's neurocognitive profile over this period. The authors believe that timely and successful treatment of VGAM in children may not only stabilize the associated cognitive deterioration but, in some cases, may ameliorate these deficits. Details of this case and a discussion of neurocognitive deficits related to VGAM are presented.

Abstract
BACKGROUND Vein of Galen malformations (VOGMs) are rare and complex congenital arteriovenous fistulas. The clinical and radiological features of VOGMs and their relation to clinical outcomes are not fully characterized. OBJECTIVE To examine the clinical and radiological features of VOGMs and the predictors of outcome in patients. METHODS We retrospectively reviewed the available imaging and medical records of all patients with VOGMs treated at the University of California, San Francisco between 1986 and 2013. Radiological and clinical features were identified. We applied the modified Rankin Scale to determine functional outcome by chart review. Predictors of outcome were assessed by χ(2) analyses. RESULTS Forty-one cases were confirmed as VOGM. Most patients (78%) had been diagnosed with VOGM in the first year of life. Age at treatment was bimodally distributed, with predominantly urgent embolization at <10 days of age and elective embolization after 1 year of age. Patients commonly presented with hydrocephalus (65.9%) and congestive heart failure (61.0%). Mixed-type (31.7%) VOGM was more common in our cohort than purely mural (29.3%) or choroidal (26.8%) types. The most common feeding arteries were the choroidal and posterior cerebral arteries. Transarterial embolization with coils was the most common technique used to treat VOGMs at our institution. Functional outcome was normal or only mildly disabled in 50% of the cases at last follow-up (median=3 years, range=0-23 years). Younger age at first diagnosis, congestive heart failure, and seizures were predictive of adverse clinical outcome. The survival rate in our sample was 78.0% and complete thrombosis of the VOGM was achieved in 62.5% of patients. CONCLUSIONS VOGMs continue to be challenging to treat and manage. Nonetheless, endovascular approaches to treatment are continuing to be refined and improved, with increasing success. The neurodevelopmental outcomes of affected children whose VOGMs are treated may be good in many cases.

Abstract
Vein of Galen aneurysmal malformations are a rare and diverse group of entities with a complex anatomy, pathophysiology, and serious clinical sequelae. Due to their complexity, there is no uniform treatment paradigm. Furthermore, treatment itself entails the risk of serious complication. Offering the best treatment option is dependent on an understanding of the aberrant anatomy and pathophysiology of these entities, and tailored therapy is recommended. Herein, the authors review the current concepts related to vein of Galen aneurysmal malformations and suggest a new classification system excluding mesodiencephalic plexiform intrinsic arteriovenous malformations from this group of malformations.
