Intracranial arteriovenous shunts (ICAVSs) in young children are characterized with frequent high flow fistulas. In association of high flow fistulas and physiological condition of the developing brain and heart, each disease tends to present at a certain age with unique symptoms. Vein of Galen aneurysmal malformation (VGAM) and dural sinus malformation (DSM) with arteriovenous (AV) shunts tend to present in neonate with high output cardiac failure. In infancy, VGAM, pial AVF and infantile dural AVF tend to present with hydrodynamic disorder such as macrocephaly, ventriculomegaly, prominent facial veins, and developmental delay...

Bilateral thalamic infarction (BTI) typically presents as a sleep-like coma (SLC) without localizing signs, posing a diagnostic challenge that may lead the treating physician to search for toxic or metabolic causes and delay treatment. We review our experience with BTI of different etiologies, and emphasize the critical role of timely imaging, diagnosis, and management in a series of 12 patients with a presentation of SLC and acute BTI who were managed in our Medical Centers from 2006-2015. In 11/12, urgent head CT scans showed normal brain tissue, while diffusion-weighted (DWI) MRI revealed symmetric bilateral thalamic hyperintense lesions with variable degrees of brainstem involvement...

We present a case of intracranial arteriovenous fistula with perimedullary venous drainage presenting with acute myelopathy, which is an unusual presentation of this uncommon condition. Subsequent catheter angiogram defined the arterial feeders from the meningohypophyseal trunk and petrosal branch of the middle meningeal artery. The patient was successfully embolised, resulting in complete obliteration of the fistula, and significant resolution of brainstem and cervical cord changes along with clinical improvement...

Neonatal neuro-intervention is challenging. The purpose of this article is to report the neuro-intervention for the neonates with brain arteriovenous fistulas (AVFs), with special reference to access routes. Fifteen neonates (12 boys and 3 girls) who underwent neuro-intervention within the first 14 days of life were -included. Their diagnoses included vein of Galen aneurysmal malformation (6), dural sinus malformations with arteriovenous (AV) shunts (6), pial AVF (2), and epidural AVF (1). Birth weight ranged from 1,538 g to 3,778 g (mean 2,525 g)...

Galenic dural arteriovenous fistula (DAVF) represents a unique, hard to treat subgroup of tentorial DAVFs. We present an unusual case of hemorrhagic Galenic DAVF in a 54-year-old woman. The fistula drained directly to the vein of Galen through multiple feeders. Complete occlusion of the fistula was achieved through transarterial embolization. Deep venous drainage remained intact and the patient recovered well. To our knowledge, this is the first report on complete closure of hemorrhagic Galenic DAVF using transarterial embolization with complete obliteration of vein of Galen...

Acquired arteriovenous malformations, such as is the case with dural arteriovenous fistulae (DAVF), are the consequence of a pathological new arterial ingrowth into venous spaces that reaches directly the venous lumen, without interposition of a capillary network, thereby creating an AV-shunt.The following concise text will provide elements in regards to diagnosis, indication for treatment discussion and choice of endovascular treatment (EVT) method.

OBJECTIVE: Trigeminal neuralgia (TN) is a rare revealing symptom of dural or cerebral arteriovenous (AV) shunt. Few isolated cases have described the association between TN and arteriovenous shunt. We presented our experience concerning cerebral AV shunt revealed by a TN. METHODS: Between 2003 and 2013, 548 brain AV malformations (bAVM) and 268 dural AV fistulas (dAVF) were treated and a retrospective analysis identified 10 consecutive cases with TN. We reviewed their clinical and angiographic data and as well as their outcome after endovascular treatment...

OBJECT The microvascular anatomy of spinal dural arteriovenous fistulas (AVFs), especially the relationships of the vessels with the dura mater, has yet to be angiographically demonstrated in detail and proven histologically. METHODS From January 2012 through April 2014, a total of 7 patients with spinal dural AVFs in the thoracic region underwent open microsurgical obliteration at Tokyo Metropolitan Neurological Hospital. The microvascular anatomy of spinal dural AVFs was comprehensively assessed by using advanced microangiography, including 3D computer graphics and intraoperative indocyanine green video angiography, and by histological findings...

Seven cases of adult spinal vascular malformations presenting in conjunction with spinal dysraphism have been reported in the literature. Two of these involved male patients with a combined dural arteriovenous fistula (DAVF) and lipomyelomeningocele. The authors present the third case of a patient with an extraspinal DAVF and associated lipomyelomeningocele in a lumbosacral location. A 58-year-old woman with rapid decline in bilateral motor function 10 years after a prior L4-5 laminectomy and cord detethering for diagnosed tethered cord underwent magnetic resonance imaging showing evidence of persistent cord tethering and a lipomyelomeningocele...

BACKGROUND CONTEXT: Spinal dural arteriovenous fistulas (AVFs) are acquired lesions presenting typically with neurologic deficits secondary to chronic congestive myelopathy. The low-flow and low-volume nature of these lesions makes hemorrhage very unlikely, and intramedullary hemorrhage caused by thoracolumbar dural AVFs is exceedingly rare. PURPOSE: The purpose of this study was to report a case of intramedullary hemorrhage caused by a thoracolumbar dural AVF. STUDY DESIGN/SETTING: The study design included a case report and review of literature...

Langer-Giedion syndrome (LGS) is a rare disease caused by deletion of chromosome 8q23.3-q24.11. Clinical manifestations include among others multiple exostoses, short stature, intellectual disability, and typical facial dysmorphism. Dural arterio-venous shunts (DAVS) in the pediatric age are rare lesions, which have been classified into three types: dural sinus malformations (DSM), infantile type DAVS (IDAVS), and adult type DAVS (ADAVS). We report a case of a patient with a known LGS who was diagnosed with complex intracranial dural AV fistula at the age of 20...

OBJECTIVES/HYPOTHESIS: A dural arteriovenous fistula (DAVF) with cortical venous reflux (CVR) is a dangerous neurovascular entity. A DAVF at the cribriform plate is typically silent until its inevitable presentation with intracranial hemorrhage. CASE SUMMARY: A 67-year-old male presented with severe epistaxis. Following unsuccessful conventional measures and a surgical exploration, a catheter angiography showed a DAVF at the cribriform plate, with its nidus extending into the nasal cavity...

A 22 -year-old man presented with 6 months of sudden onset, incapacitating, left-sided chest pain occurring 1-2 times a week. The severity of the pain caused loss of consciousness several times leading to multiple fractures. Investigation with echocardiogram, exercise tolerance test, Holter monitor, chest X-ray and V/Q scan revealed no abnormality as did EEG and 48 h video telemetry. MRI of the thoracic and lumbar spine showed a spinal dural arteriovenous fistula (SDAVF) at the level of T6, confirmed on angiogram...

BACKGROUND: Superior oblique myokymia (SOM) is a rare disorder in which the patient suffers episodic uniocular torsional eye movement associated with diplopia and oscillopsia . Although the pathophysiology has been narrowed down to erratic discharge of the trochlear nerve, yet the exact etiology remains unclear; a handful of cases have been described in association with an identifiable space occupying lesions or dural AV fistulae. Neurovascular compression theory has been postulated in the early 1980s and to our knowledge, very few reports exist in the literature accrediting this hypothesis in the pathogenesis of superior oblique myokymia...

Intracranial arteriovenous fistulas (AVFs) are rare vascular cerebral lesions composed of one or more cortical-pial arterial feeders directly connected with a single draining vein. They differ from the other AV malformations in that they lack a nidus and are located outside the dural leaflets. Because of high flow and pressure AVFs have a high risk of hemorrhage and if untreated cause death in up to 63% of cases. Treatment can be endovascular or microneurosurgical. We describe an infant with hydrocephalus and raised intracranial pressure and MRI findings of a single dilated venous vessel with a proximal varix in the perimedullary spaces confirmed by CT angiography and DSA that found a single artery-single vein fistula we successfully occluded with GDC coils...

A 37- year old male with a long history of a left orbital venous/lympathic malformation presented with ocular injection, increased proptosis and reduced left vision. Angiography demonstrated a carotid cavernous dural AV fistula combined with a concomitant venous/lymphatic malformation. After attempts at transvenous embolization, a direct uncomplicated transorbital puncture of the cavernous sinus via a lateral orbitotomy was performed with complete resolution of ocular symptoms.

We describe a rare case where a patient developed intracranial pial arteriovenous (AV) fistula due to dural tenting. The patient was a 63-year-old woman who had undergone neck clipping for an unruptured middle cerebral artery (MCA) aneurysm. The surgery was performed without any problems and her postoperative course was uneventful. Two weeks after cerebral angiography operation revealed a pial AV fistula fed by the right MCA and drained into the vein of Trolard through the Sylvian vein which had not existed before surgery...

Stereotactic radiosurgery was first described by Leksell in Stockholm, Sweden in 1951. In 1967, Leksell introduced the 'Gamma Knife' for clinical use in carefully selected patients. A major role for radiosurgery further emerged in 1972 after its application for brain arteriovenous malformations. Radiosurgery was initially used for high risk or deep seated AVMs that were unsuitable for resection or embolization. Several additional pioneers contributed towards its continued development. Stereotactic radiosurgery is now considered as an important option for patients with brain vascular malformations, including AVMs, cavernous malformations, and dural AV fistulas...
