“…To our knowledge, no treatment of mural type VAGM with WEB devices has been reported before. Liquid embolic agents—traditionally cyanoacrylate5 and, more recently, precipitating agents such as Onyx6—are well suited for choroidal type VGAM. In choroidal type malformations, a combined transarterial and transvenous approach is necessary 1 4 7–9.…”

Occlusion of a mural type vein of Galen malformation in a 10-month-old boy with three Woven EndoBridge (WEB 17) and two coils

We report the case of a 10-month-old boy with an enlarged head circumference and severe motor developmental delay. MRI showed a vein of Galen malformation (VGAM) with a heavily dilated median prosencephalic vein. Digital subtraction angiography confirmed a mural type VGAM with three feeding arteries arising from the posterior cerebral arteries. Due to the short length of the feeding arteries and the high flow, occlusion of the feeding vessels with detachable coils was not possible because of repeated coil dislocation into the dilated vein. Embolization of the three feeding vessels was then performed with a Woven EndoBridge single layer device (WEB SL17). In two arteries complete occlusion was accomplished with the WEB alone and in one artery additional deployment of two coils was necessary. Follow-up imaging at day 1 after treatment as well as 3 and 9 months after embolization showed persistent occlusion.

“…Transvenous access (TVA) has diagnostic and therapeutic utility in neuroendovascular surgery, ranging from diagnostic venography and venous sampling to transvenous embolization, thrombectomy, and stenting. TVA is considered the route of choice for the treatment of a wide range of neuroendovascular conditions that include, but are not limited to, inferior petrosal sinus sampling, mechanical thrombectomy in cerebral venous sinus thrombosis, venous stenting for idiopathic intracranial hypertension, and embolization of vein of Galen malformations, dural arteriovenous fistula, and carotid–cavernous fistula 78–87…”

The purpose of this publication is to provide a comprehensive review on the techniques and tools used for vascular access in neurointerventional procedures. Using published literature, we reviewed data on access methods, sites, tools, and techniques for neurointerventions. Recommendations are provided based on quality of data/levels of evidence and, where appropriate, expert consensus. While tools and techniques continue to be developed, current literature and experience supports certain principles regarding vascular access for neurointerventional procedures.

“…In previous literature, it was considered to be not feasible due to increased morbidity. In recent article, Orlov et al 48 considered it was a safe and effective salvage method for VGAM with restricted transarterial access. Besides, Meila et al 49 described a combined transvenous and transarterial approach, called kissing microcatheter technique.…”

“…In mural type, NBCA is a preferred embolic material due to the properties of quick precipitation and adhesion to vessel. 48 In addition, Joo et al 42 first reported a patient with a mural-type VGAM who was successfully treated using the Micro Vascular Plug system, which may be a potential available option.…”

Vein of Galen aneurysmal malformation (VGAM) is a rare intracranial vascular anomaly in the choroidal arteries characterized by the persistence of the embryonic median prosencephalic vein of Markowski (MProsV). It is common in children with high mortality and disability rates. VGAM-associated clinical presentations include heart failure, hydrocephalus, and neurological symptoms, which make it difficult for diagnosis. Simultaneously, the complex VGAM vascular architecture, characterized by a wide interindividual variability, makes the management of this condition challenging to clinicians. Thus, timely diagnosis and treatment of VGAM are crucial. In this review article, we elucidated the latest research progresses of VGAM in the aspects of the pathogenesis, classification, clinical features, imaging, management, and prognosis based on recent relevant literatures. It is beneficial to raise the awareness of VGAM and improve the level of management and treatment.

Superselective transvenous embolization with Onyx and n-BCA for vein of Galen aneurysmal malformations with restricted transarterial access: safety, efficacy, and technical aspects

Abstract: 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.
