Fetal and Neonatal MRI Predictors of Aggressive Early Clinical Course in Vein of Galen Malformation.

AJNR Am J Neuroradiol 2020 May 28. Epub 2020 May 28.

From the Departments of Neurosurgery (L.A., M.L., A.M., D.B.O.)

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.

Neuroangiography: Review of Anatomy, Periprocedural Management, Technique, and Tips.

Semin Intervent Radiol 2020 Jun 14;37(2):166-174. Epub 2020 May 14.

Department of Neurosurgery, University of Colorado School of Medicine, Aurora, Colorado.

Neuroangiography (NA) is a minimally invasive procedure used to diagnose patients with neurovascular diseases. Noninvasive imaging has improved dramatically in recent years and is utilized more frequently; however, further evaluation with NA is still required in certain cases. NA indications include intracranial (cerebral aneurysms, arteriovenous malformations, dural arteriovenous fistula, cerebral vasculitis, cerebral vasospasm, ischemic stroke, nontraumatic subarachnoid hemorrhage, intracerebral hemorrhage, Moyamoya, vein of Galen malformation, intracranial tumors, and pseudotumor cerebri) and extracranial (internal and common carotid artery stenosis, vertebral artery stenosis, carotid artery blowout, vertebral artery blowout, epistaxis, oropharyngeal bleeding, and carotid body tumor) pathologies which can help with diagnosis and potential subsequent endovascular treatment.

High-Flow Vascular Malformations in Children.

Semin Neurol 2020 Jun 6;40(3):303-314. Epub 2020 Apr 6.

Department of Neurological Surgery, University of California San Francisco, San Francisco, California.

Children can have a variety of intracranial vascular anomalies ranging from small and incidental with no clinical consequences to complex lesions that can cause substantial neurologic deficits, heart failure, or profoundly affect development. In contrast to high-flow lesions with direct arterial-to-venous shunts, low-flow lesions such as cavernous malformations are associated with a lower likelihood of substantial hemorrhage, and a more benign course. Management of vascular anomalies in children has to incorporate an understanding of how treatment strategies may affect the normal development of the central nervous system. Read More

Division of Neonatology, The Hospital for Sick Children, Toronto, Canada.

Vein of Galen malformation results in predictable changes in physiology which exist on a continuum. Severe pulmonary hypertension may present as hypoxemia; however, excessive reduction in pulmonary vascular resistance may precipitate progressive pulmonary overcirculation and impaired systemic blood flow. Right ventricular performance and the patency and direction of the ductus arteriosus may play a crucial role in postductal organ perfusion. Read More

World Neurosurg 2019 Jun 5;126:405-412. Epub 2019 Mar 5.

Department of Neurological Surgery, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin, USA; Department of Radiology, University of Wisconsin School of Medicine and Public Health, Madison, Wisconsin, USA. Electronic address:

Background: Vein of Galen malformations (VoGMs) induce cerebrovascular dysfunction through arterial steal and venous hypertension resulting, if untreated, in severe neurologic morbidity and mortality. Noninvasive techniques for quantitative, serial evaluation of cerebrovascular hemodynamics in VoGMs are lacking. This proof of concept study using quantitative blood flow measurements from 4-dimensional flow magnetic resonance imaging may be useful as a noninvasive biomarker to guide timing of intervention and assess disease progression and treatment outcomes.

Department of Neurosurgery, Yale School of Medicine, New Haven CT, USA; Department of Pediatrics, Yale School of Medicine, New Haven CT, USA; Department of Cellular and Molecular Physiology, Yale School of Medicine, New Haven CT, USA. Electronic address:

Recent whole exome sequencing studies in humans have provided novel insight into the importance of the ephrinB2-EphB4-RASA1 signaling axis in cerebrovascular development, corroborating and extending previous work in model systems. Here, we aim to review the human cerebrovascular phenotypes associated with ephrinB2-EphB4-RASA1 mutations, including those recently discovered in Vein of Galen malformation: the most common and severe brain arteriovenous malformation in neonates. We will also discuss emerging paradigms of the molecular and cellular pathophysiology of disease-causing ephrinB2-EphB4-RASA1 mutations, including the potential role of somatic mosaicism. Read More

A Severe Case of Aneurysmal Malformation of the Vein of Galen, Cardiac Failure and Intrauterine Fetal Death.

Curr Health Sci J 2018 Jan-Mar;44(1):76-79. Epub 2018 Mar 29.

Department of Obstetrics and Gynecology, University of Medicine and Pharmacy of Craiova, Romania.

Aneurism of the vein of Galen is a rare congenital anomaly, where complex arteriovenous malformation are identified between multiple choroidal arteries and the median prosencephalic vein of Markowski, which is a precursor of the vein of Galen, with subsequent aneurysmal enlargement of the respective arteriovenous system. The congenital malformation develops during week 6 to 11 of fetal development. Infants often die from high-output congestive heart failure. Read More

Distal microcatheter placement using the Asahi Chikai 0.008-inch micro-guidewire for liquid embolic material delivery: A technical note.

World Neurosurg 2019 Jan 4. Epub 2019 Jan 4.

Department of Neurosurgery, Icahn School of Medicine ,Mount Sinai Health Care System, New York, New York,USA.

Introduction: Management of vascular malformations requires microcatheter manipulation through distal tortuous arterial feeders less than a millimetre in diameter, to permit safe and effective embolization at the fistula or nidus location. The Asahi Chikai 0.008 inch micro-guidewire recently introduced in the United States was used to evaluate microcatheter torque, support and safety in distal microcatheter navigation. Read More

Mutations in Chromatin Modifier and Ephrin Signaling Genes in Vein of Galen Malformation.

Neuron 2019 02 18;101(3):429-443.e4. Epub 2018 Dec 18.

Department of Neurosurgery, Yale School of Medicine, New Haven, CT, USA; Department of Pediatrics, Yale School of Medicine, New Haven, CT, USA; Department of Cellular and Molecular Physiology, Yale School of Medicine, New Haven, CT, USA. Electronic address:

Normal vascular development includes the formation and specification of arteries, veins, and intervening capillaries. Vein of Galen malformations (VOGMs) are among the most common and severe neonatal brain arterio-venous malformations, shunting arterial blood into the brain's deep venous system through aberrant direct connections. Exome sequencing of 55 VOGM probands, including 52 parent-offspring trios, revealed enrichment of rare damaging de novo mutations in chromatin modifier genes that play essential roles in brain and vascular development.

Fetal stroke and cerebrovascular disease: Advances in understanding from lenticulostriate and venous imaging, alloimmune thrombocytopaenia and monochorionic twins.

Eur J Paediatr Neurol 2018 Nov 11;22(6):989-1005. Epub 2018 Sep 11.

Departments of Child Health, Obstetrics and Gynaecology and Radiology, University Hospital Southampton, United Kingdom; Clinical and Experimental Sciences, University of Southampton, United Kingdom.

Fetal stroke is an important cause of cerebral palsy but is difficult to diagnose unless imaging is undertaken in pregnancies at risk because of known maternal or fetal disorders. Fetal ultrasound or magnetic resonance imaging may show haemorrhage or ischaemic lesions including multicystic encephalomalacia and focal porencephaly. Serial imaging has shown the development of malformations including schizencephaly and polymicrogyra after ischaemic and haemorrhagic stroke. Read More
