Injection of N‑butyl Cyanoacrylate Through a Dual-Lumen Balloon for Embolization of High-flow Intranidal Fistulas in Brain Arteriovenous Malformations: Technical Note.

Clin Neuroradiol 2019 Apr 10. Epub 2019 Apr 10.

Department of Neuroradiology, Pitié-Salpêtrière Hospital, 47 Boulevard de l'Hôpital, 75013, Paris, France.

Purpose: N-butyl cyanoacrylate (NBCA) glue is a valuable liquid embolic agent for the endovascular treatment of brain arteriovenous malformations (BAVM). The use of NBCA carries a risk of embolic agent reflux and distal migration with ensuing possibility of venous drainage compromise. The aim of this technical note is to describe a single center case series of high-flow intranidal fistulas embolized though a dual lumen balloon under local flow-arrest conditions. Read More

[Immediate outcomes of microsurgical treatment of cerebral arteriovenous malformations in non-hemorrhagic patients].

Zh Vopr Neirokhir Im N N Burdenko 2018;82(6):30-37

Burdenko Neurosurgical Institute, Moscow, Russia.

Arteriovenous malformations (AVMs) are some of the most frequent congenital abnormalities of the cerebral vascular system and usually occur at a young age. Given the fact that AVMs can manifest, in addition to hemorrhages, as symptomatic epilepsy (17-40%) that occurs more often at a young age and may lead to significant disability, investigation of this pathology remains topical. Particular attention has recently been paid to the management of AVM patients without clinical signs of hemorrhage at the time of pathology diagnosis. Read More

Hereditary hemorrhagic telangiectasia (HHT) is generally considered a disorder of endothelial dysfunction, characterized by the development of multiple systemic arteriovenous malformations (AVMs), including within the brain. However, there have recently been a number of reports correlating HHT with malformations of cortical development, of which polymicrogyria is the most common type. Here we present 7 new cases demonstrating polymicrogyria in HHT, 6 of which demonstrate a brain AVM (bAVM) in close spatial proximity, with the aim of providing a common origin for the association.

Characterization of Endothelial Cilia Distribution During Cerebral-Vascular Development in Zebrafish ( Danio rerio).

Arterioscler Thromb Vasc Biol 2018 Dec;38(12):2806-2818

Division of Neonatology, Department of Pediatrics (S.P., P.M.S., R.R.), Medical College of Wisconsin, Milwaukee.

Objective- Endothelial cells (ECs) sense and respond to flow-induced mechanical stress, in part, via microtubule-based projections called primary cilia. However, many critical steps during vascular morphogenesis occur independent of flow. The involvement of cilia in regulating these stages of cranial vascular morphogenesis is poorly understood because cilia have not been visualized in primary head vessels. Read More

Proceedings of the 2018 next-generation Gamma Knife research meeting.

J Neurosurg 2018 Dec;129(Suppl1):5-9

7Department of Radiation Oncology, Sunnybrook Health Sciences Centre, University of Toronto, Ontario, Canada.

In order to determine what areas of research are a clinical priority, a small group of young Gamma Knife investigators was invited to attend a workshop discussion at the 19th International Leksell Gamma Knife Society Meeting. Two areas of interest and the need for future radiosurgical research involving multiple institutions were identified by the young investigators working group: 1) the development of additional imaging sequences to guide the understanding, treatment, and outcome tracking of diseases such as tremor, radiation necrosis, and AVM; and 2) trials to clarify the role of hypofractionation versus single-fraction radiosurgery in the treatment of large lesions such as brain metastases, postoperative cavities, and meningiomas.

Integration of rotational angiography enables better dose planning in Gamma Knife radiosurgery for brain arteriovenous malformations.

J Neurosurg 2018 Dec;129(Suppl1):17-25

Departments of1Neurosurgery and.

OBJECTIVEIn Gamma Knife radiosurgery (GKS) for arteriovenous malformations (AVMs), CT angiography (CTA), MRI, and digital subtraction angiography (DSA) are generally used to define the nidus. Although the AVM angioarchitecture can be visualized with superior resolution using rotational angiography (RA), the efficacy of integrating RA into the GKS treatment planning process has not been elucidated.METHODSUsing data collected from 25 consecutive patients with AVMs who were treated with GKS at the authors' institution, two neurosurgeons independently created treatment plans for each patient before and after RA integration.

Vis-à-vis: a focus on genetic features of cerebral cavernous malformations and brain arteriovenous malformations pathogenesis.

Neurol Sci 2019 Feb 6;40(2):243-251. Epub 2018 Dec 6.

Department of Biomedical and Dental Science and Morphological and Functional Images, University of Messina, Consolare Valeria street 1, 98125, Messina, Italy.

Cerebrovascular malformations include a wide range of blood vessel disorders affecting brain vasculature. Neuroimaging differential diagnosis can result unspecific due to similar phenotypes of lesions and their deep localization. Next-generation sequencing (NGS) platforms simultaneously analyze several hundreds of genes and can be applied for molecular distinction of different phenotypes within the same disorder's macro-area.

Transtentorial Approach for Parahippocampal Gyrus Arteriovenous Malformation Resection: 3-Dimensional Operative Video.

Oper Neurosurg (Hagerstown) 2019 Mar;16(3):E83-E84

Department of Neurosurgery, Universidade Federal de Sao Paulo, São Paulo, São Paulo, Brazil.

Medial temporal basal arteriovenous malformations (AVMs) have complex anatomy. They usually drain to the basal vein of Rosenthal, and arterial feeders can arise from the anterior choroidal artery and its branches, or from the posterior cerebral artery. If the AVM is more posterior in the parahippocampal gyrus, there is a predominance of arterial feeders arising from P2P or P3 segments of the posterior cerebral artery. Read More

Indocyanine Green Videoangiography in the Surgical Treatment of Spinal Dural Arterovenous Fistula: A Useful Application.

World Neurosurg 2019 Feb 24;122:508-511. Epub 2018 Nov 24.

Department of Medico-Surgical Sciences and Biotechnologies, Sapienza University of Rome, Rome, Italy; Division of Neurosurgery, IRCCS Neuromed, Pozzilli (IS), Italy.

Background: Indocyanine green videoangiography (ICG-V) is used with increasing frequency in neurovascular surgery. ICG-V use in spinal dural arteriovenous fistulas (DAVFs) allows visualization of the hemodynamics of the fistula and to confirm its exclusion after ligation of the feeder. Here, we illustrate how ICG-V is useful for centering the surgical exposure during mini-invasive approaches to spinal DAVFs. Read More

[Treatment of a Traumatic Direct Carotid Cavernous Fistula with an Intradural Internal Carotid Artery Pseudoaneurysm Using a Low-profile Visualized Intraluminal Support(LVIS)Stent:A Case Report].

No Shinkei Geka 2018 Nov;46(11):989-997

Department of Neurosurgery, Higashihiroshima Medical Center.

Traumatic carotid cavernous fistula(CCF)is known to present a direct connection between the cavernous segment of the internal carotid artery(ICA)and the cavernous sinus(CS). In rare cases, the fistula is formed between the intradural internal carotid artery(ICA)and the cavernous sinus(CS)via a pseudoaneurysm(pAN), requiring appropriate management and aggressive surgical treatment. We describe a 58-year-old man who sustained a severe head injury diagnosed as traumatic CCF treated with an intradural pAN procedure and transarterial coil embolization combined with a Low-profile Visualized Intraluminal Support(LVIS)stent.

Utility of Video Indocyanine Angiography to Detect the Cortical Entry Point of a Draining Vein with a Superficial Vein During Arteriovenous Malformation Surgery.

World Neurosurg 2019 Feb 15;122:428. Epub 2018 Nov 15.

Department of Neurosurgery, Helsinki University and Helsinki University Hospital, Helsinki, Finland.

Resection of brain arteriovenous malformation (AVM) is challenging, particularly if the feeder arteries and draining vein are not directly visible on the surface. Indocyanine green video angiography can assist in detection of the connecting point of the draining vein with the superficial vein and can thus localize the cortical entry point for AVM resection. Here, we present a case of a 27-year-old man with headache. Read More
