Background: An estimated 0.1% of the population harbors brain arteriovenous malformations (AVMs). Diagnosis and workup of AVMs include thorough evaluation for characterization of AVM angioarchitecture and careful assessment for concomitant aneurysms. The presence of coexisting aneurysms is associated with an increased risk of intracranial hemorrhage, with a published risk of 7% per year compared to patients with AVMs alone with a risk of 3%. Comprehensive AVM management requires recognition of concomitant aneurysms and prioritizes treatment strategies to mitigate the aggregate risk of intracranial hemorrhage associated with AVM rupture in patients with coexisting aneurysms...

Stereotactic radiosurgery (SRS) is commonly used in the treatment of brain metastases, benign tumors, and arteriovenous malformations (AVM). Single-fraction radiosurgery, though ubiquitous, is limited by lesion size and location. In these cases, hypofractionated radiosurgery (hfSRS) offers comparable efficacy and toxicity. We review the recent literature concerning hfSRS in the treatment of brain metastases, benign tumors, and AVMs that are poorly suited for single-fraction SRS. Published retrospective analyses suggest that local control rates for brain metastases and benign tumors, as well as the rates of AVM obliteration, following hfSRS treatment are comparable to those reported for single-fraction SRS...

INTRODUCTION: Arteriovenous malformations (AVMs) are a type of vascular malformation characterised by an abnormal connection between arteries and veins, bypassing the capillary system. This absence of capillaries generates an elevated pressure (hyperdebit), in both the AVM and the venous drainage, increasing the risk of rupture. Management modalities are: observation, microsurgical clipping, endovascular treatment and radiosurgery. The former can be used alone or in the frame of a multidisciplinary approach...

BACKGROUND AND PURPOSE: Brain arteriovenous malformation (bAVM) is an important risk factor for intracranial hemorrhage. Current treatments for bAVM are all associated with considerable risks. There is no safe method to prevent bAVM hemorrhage. Thalidomide reduces nose bleeding in patients with hereditary hemorrhagic telangiectasia, an inherited disorder characterized by vascular malformations. In this study, we tested whether thalidomide and its less toxic analog, lenalidomide, reduce bAVM hemorrhage using a mouse model...

Because of the more frequent use of noninvasive imaging methods, arteriovenous malformation (AVM) are gaining more attention. Population based studies reveal that about 35% to 50% of patients with AVM initially present with hemorrhage. Prior hemorrhage is the most consistent risk factor for future hemorrhage, other risk factors include deep venous drainage pattern, deep location, and so on. Surgical interventions, including surgical excision, intravascular intervention, and stereotactic radiation, have been developed with the aim at eliminating this source of hemorrhage...

OBJECTIVES: Finding the underlying cause for pulsatile tinnitus can be challenging. We aimed to determine the incidence of arteriovenous shunts, i.e., arteriovenous malformations (AVMs) or dural arteriovenous fistulas (dAVFs), in patients referred for catheter angiography (digital subtraction angiography [DSA]). Furthermore, we assessed which clinical features were predictive for the presence of such a lesion. STUDY DESIGN AND METHODS: Fifty-one patients with pulsatile tinnitus, who were referred to us for DSA to exclude an arteriovenous shunt, were enrolled, prospectively...

Brain arteriovenous malformations (AVM) are complex and highly challenging lesions, for which intra-operative indocyanin green fluorescence video angiography is widely used. Fluorescein video angiography (FVA) recently appeared as an alternative technique but the feasibility and usefulness of this technique is yet uncertain. This short series reports our preliminary experience of FVA in intracranial AVM surgery. We retrospectively studied the cases of seven patients who had FVA for an AVM surgery. The primary objective of this study was to assess the utility of FVA as judged by the surgeon...

BACKGROUND: The extent of red blood cell units (RBC) needed for different neurosurgical procedures and the time point of their administration are widely unknown, which results in generously cross-matching prior to surgery. However, RBC are increasingly requested in the aging western populations, and blood donations are significantly reduced. Therefore, the knowledge of the extent and time point of administration of RBC is of major importance. METHODS: This is a retrospective single center analysis...

REVIEW

The anterior choroidal artery (AChA) is a critical artery in brain physiology and function. The AChA is involved in many diseases, including aneurysm, brain infarct, Moyamoya disease (MMD), brain tumor, arteriovenous malformation (AVM), etc. The AChA is vulnerable to damage during the treatment of these diseases and is thus a very important vessel. However, a comprehensive systematic review of the importance of the AChA is currently lacking. In this study, we used the PUBMED database to perform a literature review of the AChA to increase our understanding of its role in neurophysiology...

PURPOSE OF REVIEW: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant inherited disease characterized by telangiectasia and arteriovenous malformations (AVMs). To date, five genetic types of HHT and one combined juvenile polyposis syndrome and HHT are known. Clinical and genetic screening of patients suspected with HHT is recommended to confirm the diagnosis and to prevent complications associated with HHT. The aim of this article is to give an overview of the evidence and to formulate a recommendation for clinicians concerning screening for HHT...

BACKGROUND: Sporadic vascular malformations (VMs) are complex congenital anomalies of blood vessels that lead to stroke, life-threatening bleeds, disfigurement, overgrowth, and/or pain. Therapeutic options are severely limited, and multidisciplinary management remains challenging, particularly for high-flow arteriovenous malformations (AVM). METHODS: To investigate the pathogenesis of sporadic intracranial and extracranial VMs in 160 children in which known genetic causes had been excluded, we sequenced DNA from affected tissue and optimized analysis for detection of low mutant allele frequency...

OBJECTIVES: Arteriovenous malformations (AVMs) are complex vascular lesions. Surgical excision is the treatment of choice, but is often not achievable. Embolo-sclerotherapy alone is associated with high recurrence rates. This study tested the hypothesis that seeding hydrogel conditioned bone marrow derived mesenchymatous stem cells (BM-MSCs) in an AVM nidus model induces solid microvascular occlusion through endoluminal tissue growth. METHODS: AVMs were modelled as arteriovenous microvascular nidus, using swine rete mirabile, a plexiform intracranial structure composed of arterial microvessels that extensively anastomose...

The risks and benefits of arteriovenous malformation (AVM) treatment should be considered cautiously in each patient since management strategy of it depends on various factors including age of the patient, location and volume of AVM and presence of other vascular abnormalities. Current management options of AVM include observation, endovascular embolization, radiosurgery and microsurgical resection or in combination of any two of the above procedures. Here, we have discussed a case of intracranial AVM with radiation induced early cyst formation, and performed a literature review to determine the optimum treatment of complex intracranial AVM...
