High Output Cardiovascular Physiology and Outcomes in Fetal Diagnosis of Vein of Galen Malformation.

Pediatr Cardiol 2021 May 8. Epub 2021 May 8.

Pediatric Heart Center, Icahn School of Medicine At Mount Sinai, New York, NY, USA.

Vein of Galen aneurysmal malformation (VGAM) is a rare anomaly associated with poor outcomes from high output cardiac failure and neurologic complications. Studies addressing fetal cardiovascular status and outcomes in this population are limited. A single-center retrospective review was conducted on patients with a prenatal diagnosis of VGAM who underwent a fetal echocardiogram between January 2015 and July 2019. Read More

Coil assisted glue embolization to improve safety and accuracy in endovascular management of Vein of Galen patients.

Clin Neurol Neurosurg 2021 Apr 21;205:106652. Epub 2021 Apr 21.

Army Hospital (Referral & Research), Delhi Cantt, New Delhi 110010, India. Electronic address:

Background: Vein of Galen malformation (VOGM) patients present in neonatal age with cardiac failure or significant neurologic consequences. The most established method of treatment has been transarterial embolization with high concentration glue (N-Butyl Cyano Acrylate) which may be difficult to control due to very high flow rates and may migrate to the venous side with undesirable consequences. We describe our experience in four patients in whom initial coil placement in prominent feeding arteries helped inflow reduction thereby facilitating controlled glue injection with a good result and no incidence of non-target embolization.

Interv Neuroradiol 2021 Feb 20:1591019921993368. Epub 2021 Feb 20.

Department of Neurosurgery, North Shore University Hospital, Manhasset, NY, USA.

Background: Even in the modern endovascular era, the treatment of Vein of Galen Malformations (VOGM) is extremely challenging. While their natural history is very poor, endovascular embolization has emerged as the standard of care.

Spontaneous thrombosis of a vein of Galen malformation associated with acute sinusitis: a case report.

Childs Nerv Syst 2021 Feb 17. Epub 2021 Feb 17.

Department of Neurosurgery, Fundación Santafé de Bogotá, Carrera 7 No. 117 - 15, Bogotá, Colombia.

The vein of Galen malformation is caused by an abnormal shunting between choroidal arteries and the median prosencephalic vein during embryological development, leading to increased blood flow to the deep cerebral veins, intracranial damage, and systemic repercussions. Idiopathic spontaneous thrombosis of a vein of Galen malformation is rare, and its association with acute sinusitis has not been reported in the literature. We present the case of a girl with a postnatal diagnosis of a vein of Galen malformation at the age of 16 months, with secondary pulmonary hypertension that was adequately controlled with spironolactone.

Handb Clin Neurol 2021 ;176:305-323

Dotter Department of Interventional Radiology, Oregon Health and Science University, Portland, OR, United States. Electronic address:

The pediatric neurovascular disease runs the chronologic spectrum with dramatic changes in the presentation, evaluation, and treatment from the prenatal, perinatal, and infant periods through childhood and adolescence. These diseases are often dynamic throughout this period and the dynamic continues throughout life. There are four major categories: high-flow arteriovenous shunting lesions, arterial aneurysms, low-flow vascular lesions, and vascular occlusive disease. Read More

Cerebral arteriovenous fistulae.

Handb Clin Neurol 2021 ;176:179-198

Departments of Radiology and Biomedical Imaging, Neurological Surgery, Neurology, and Anesthesia and Perioperative Care, University of California San Francisco, School of Medicine, San Francisco, CA, United States.

Dural arteriovenous fistulae (dAVFs) are diverse, complex lesions that share the common feature of arteriovenous shunting without an intervening nidus. In this chapter, the ensuing discussion is organized by dAVF location, followed by further consideration of less common, distinct types of dAVFs-carotid cavernous fistulae, pial arteriovenous fistulae, and vein of Galen malformations. For each lesion type, epidemiology, clinical presentation, imaging findings, classification considerations, and treatment options are discussed. Read More

Case report of a vertical straight sinus with hydrocephalus and Chiari I malformation.

Anat Cell Biol 2020 Dec;53(4):516-518

Department of Neurosurgery, Tulane Center for Clinical Neurosciences, Tulane University School of Medicine, New Orleans, LA, USA.

The straight sinus is a division of the dural venous sinuses, found beneath the splenium of the corpus callosum. At the internal occipital protuberance, it comes together with the superior sagittal sinus and transverse sinus to form the torcular Herophili. It functions as a major site of venous drainage for the cerebellum, inferior sagittal sinus, and vein of Galen. Read More

Abnormalities of the Fetal Central Nervous System: Prenatal US Diagnosis with Postnatal Correlation.

Radiographics 2020 Sep-Oct;40(5):1458-1472. Epub 2020 Jul 24.

From the Department of Radiology (S.W.C., S.V.G.) and Department of Obstetrics & Gynecology (B.K.B.), Duke University, 2301 Erwin Rd, Box 3808, Durham, NC 27710.

Fetal central nervous system (CNS) abnormalities are second only to cardiac malformations in their frequency of occurrence. Early and accurate diagnosis at prenatal US is therefore essential, allowing improved prenatal counseling and facilitating appropriate referral. Thorough knowledge of normal intracranial anatomy and adoption of a logical sonographic approach can improve depiction of abnormal findings, leading to a more accurate differential diagnosis earlier in pregnancy.

Peculiar Characteristics of Arteriovenous Malformations Arising in the Galenic Region.

Diagnostics (Basel) 2020 Jul 15;10(7). Epub 2020 Jul 15.

Department of Neurosurgery, The University of Tokyo Hospital, Tokyo 1138655, Japan.

Arteriovenous malformations (AVM) are congenital vascular lesions fed by arterial feeders originating from branches of the internal carotid artery (ICA) or vertebrobasilar artery. We experienced unique AVMs arising in the midline Galenic region, receiving blood supply from the ICA/vertebral artery systems and the external carotid artery system. We retrospectively reviewed data on eight patients who had an AVM arising in the Galenic region and were treated in the University of Tokyo Hospital between 1990 and 2019. Read More
