We describe a case of reproducible asystole during endovascular treatment of a posterior fossa dural arteriovenous fistula. Catheterisation of the posterior meningeal artery, a branch of the vertebral artery in this patient, followed by dimethyl sulfoxide injection prior to Onyx administration resulted in two episodes of asystole.To the best of our knowledge, this is the first reported case of asystole occurring during endovascular intervention in the posterior meningeal artery. This may represent a previously undescribed variant of the trigemino-cardiac reflex (TGCR) caused by chemical stimulation of small areas of trigeminally innervated posterior fossa dura...

BACKGROUND AND PURPOSE: The early diagnosis of spinal vascular malformations suffers from the nonspecificity of their clinical and radiologic presentations. Spinal angiography requires a methodical approach to offer a high diagnostic yield. The prospect of false-negative studies is particularly distressing when addressing conditions with a narrow therapeutic window. The purpose of this study was to identify factors leading to missed findings or inadequate studies in patients with spinal vascular malformations...

BACKGROUND AND PURPOSE: We have found DSA-Dynavision with multiplanar reconstruction very helpful in understanding the complex anatomy and planning of treatment of carotico-cavernous fistulas. The purpose of our study was to examine whether using DSA-Dynavision in pretreatment planning results in better outcome after endovascular treatment of dural arterio-venous fistulas (dAVFs). METHODS: Patients with dAVF treated with endovascular embolization were retrospectively identified from our interventional neuroradiology database...

We report a case of dural arteriovenous fistula at the left transverse sinus and sigmoid sinus(TS-dAVF), which was treated with transvenous embolization(TVE)by direct puncture of the superior sagittal sinus(SSS)under indocyanine green(ICG)fluoroscopic guidance. A 71-year-old woman presented with pulsatile tinnitus and progressive dementia. A left TS-dAVF with retrograde SSS and cortical venous reflux(Cognard type IIb)was demonstrated on cerebral angiography. The left internal jugular vein and distal portion of the right transverse sinus were occluded...

BACKGROUND: Tentorial dural arteriovenous fistulas(dAVFs)are a rare clinical entity accounting for less than 10% of all intracranial dAVFs. Because these lesions are characterized by high hemorrhagic risk, aggressive treatment should be considered. Although the number of reported cases treated with endovascular transarterial embolization(TAE)using glue has been increasing, little is known about the transvenous approach. Here, we report the case of a patient with a tentorial dAVF who was successfully treated with transvenous embolization(TVE)through venous drainage using a double catheterization technique...

A dural arteriovenous fistula (DAVF) with spinal perimedullary venous drainage can cause progressive myelopathy, and it is sometimes incorrectly diagnosed as another spinal cord disease. Here we report the cases of three individuals with a DAVF (one craniocervical junction DAVF and two tentorial DAVFs) with progressive myelopathy showing unique magnetic resonance (MR) imaging findings. MR T2*WI or susceptibility-weighted imaging (SWI) demonstrated symmetrical dark signal intensity lesions predominantly in the dorsal aspect of medulla and the central gray matter of cervical spinal cord that showed the "black butterfly" silhouette...

BACKGROUND: Dural arteriovenous fistulas (dAVF)s are often treated via transarterial or transvenous embolization. Incomplete penetration of the draining vein/occult residual will often become apparent on follow-up angiography, requiring repeat embolization, or at times, surgical resection. CASE DESCRIPTION: A 41 year old female presented with cerebellar hemorrhage from a tentorial dAVF treated with transvenous coil embolization. Follow-up angiography disclosed a residual/recurrent fistula treated with transvenous Onyx embolization...

OBJECTIVE: This is a case report of an adult male with complex type IV intraosseous DAVF causing severe venous hypertension and bony destruction, presenting with severe hemotympanum, and a novel way of staged arterial and venous embolizations to treat the emergent symptoms. METHODS: First and second stages were direct selective arterial embolizations using Onyx liquid agent. Goal was to reduce flow into the fistula by embolizing the feeder branch and distal penetration of the nidus with Onyx...

OBJECTIVES: Arteriovenous malformations (AVMs) of the superior cerebellar vermis and dural arteriovenous fistulas (dAVFs) draining into tentorial venous structures are uncommon lesions. Various surgical approaches and positions have been used to gain access. METHODS: We present our experience with 10 superior vermian AVMs and 3 dAVFs with retrograde transverse sinus or torcular drainage, each resected through a supracerebellar infratentorial approach in park bench position with modification of the neck and head position (vertex tilt-up instead of down)...

INTRODUCTION: Spinal dural arteriovenous fistulae (sdAVF) are rare lesions. Patients typically present with slowly progressive myelopathy that is often mistaken for degenerative cervical or lumbar stenosis. On spinal magnetic resonance imaging (MRI), multisegmental T2 hyperintensities along with associated flow voids are pathognomonic of sdAVF. However, diagnosis can be difficult. Definitive diagnosis and localization is achieved with complete spinal angiography. Treatment options include open surgical ligation, endovascular embolization or multimodality treatment...

BACKGROUND: and Importance Although multifocal spinal arteriovenous malformations (SAVMs) have been reported before, the present case is the first case of two different types, including perimedullary arteriovenous fistula (PMAVF) and spinal dural arteriovenous fistulas (SDAVFs) of lumbosacral arteriovenous malformations (AVMs), coexisting in one patient. We also report the use of hybrid techniques in the treatment of concomitant lumbosacral SAVMs for the first time. CLINICAL PRESENTATION: A 65-year-old man presented with a 4-year history of progressive sensory, motor, and sphincter dysfunction...

Spinal vascular malformations are uncommon yet important spinal pathologies commonly classified in congenital and acquired lesions. Spinal lipomas consist of three subtypes: intramedullary lipomas, lipomyelo(meningo)celes and lipomas of the filum. Although the association of spinal arteriovenous malformations (AVM) with other congenital anomalies is well known, the coexistence of dural arteriovenous fistulas (AVF) and tethered spinal cord is exceptionally rare and only eight cases have been reported. We present two cases from our institution and speculate on the possible origin of such a rare but insidious association...

OBJECTIVE: To evaluate the use of functional scores as predictors of symptom outcomes in patients with dural arteriovenous fistulas (dAVF) and Foix-Alajouanine syndrome. METHODS: The literature was systematically surveyed to identify patients. Aminoff-Logue Scale (ALS) and modified Rankin Scale (mRS) scores were ascertained and combined to form a novel functional score, the Aminoff-Rankin Composite (ARC) score. Subgroup analyses were performed for the comparison of surgery versus embolization and for patients with symptom duration less than 6 months...

Development of dural arteriovenous fistula (dAVF) after cerebral venous sinus thrombosis (CVST) was very uncommon and for all these reported cases, the dAVF was a chronic complication. We present a case of acute development of dAVF after CVST. A 40-year-old female was admitted into our department with 2day's headache and vomiting for 9h. Head computed tomography (CT) scan showed only scattered minor hematomas over the right frontal lobe. Blood test indicated an elevated D-dimer. The patient experienced transient paralysis (Todd's paralysis) after intermittent focal epilepsy from day 3, which progressed into sustained epilepsy on day 6...

Dural arteriovenous fistula (DAVF) in a sinus of the lesser sphenoid wing (SLSW) is rarely reported. Here, we report a case of an isolated SLSW DAVF treated by coils placed into the sinus through the feeding artery. A 68-year-old man was admitted to our hospital with headache. Magnetic resonance images and an angiogram showed a varix in the right middle cranial fossa. A DAVF, consisting of three main feeders and the isolated SLSW, was diagnosed based on the angiogram findings. Retrograde leptomeningeal venous drainage to the deep middle cerebral vein was observed...

BACKGROUND: Although an asymptomatic spinal dural arteriovenous fistula (SDAVF) can sometimes be incidentally detected on magnetic resonance imaging (MRI), there are no previous reports showing the development of an SDAVF on MRI or magnetic resonance angiography (MRA). CASE DESCRIPTION: A 64-year old man with unruptured vertebral artery dissection (VAD) developed a subarachnoid hemorrhage (SAH) during regular follow-up. Emergent endovascular coil internal trapping for the VAD was performed; however, angiography after the endovascular treatment showed a lower cervical SDAVF...

Dural arteriovenous fistula(dAVF)is relatively rare, and its etiology remains uncertain. Generally, dAVF is thought to be acquired and has been reported to develop secondary to sinus thrombosis, head injury, infection, and surgery. We report a rare case of dAVF in the anterior cranial fossa that developed remote from the craniotomy site after surgery. A 52-year-old man underwent surgery for hypertensive intracerebral hemorrhage 4 years prior. Perioperative imaging modalities demonstrated no abnormal vascular malformation except for an un-ruptured anterior communicating artery aneurysm...

BACKGROUND: Spinal dural arteriovenous fistula (DAVF) is a rare disease and multiple concurrent lesions are extremely rare. Such multiple spinal DAVFs have similar outflow routes at neighboring levels. However, there have been no reported cases of remote lesions of multiple spinal DAVFs. The authors herein report a case of double synchronous cervical and sacral DAVFs. CASE DESCRIPTION: A 56-year-old man with no prior history of disease presented with progressive myelopathy, and spinal magnetic resonance imaging (MRI) showed extensive edema of the spinal cord from the conus to T7...
