Dural AV

Yasunari Niimi
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...

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...

Spinal dural arteriovenous fistula (SDAVF) is the most common spinal vascular malformation, however it is still rare and underdiagnosed. Magnetic resonance imaging findings such as spinal cord edema and dilated and tortuous perimedullary veins play a pivotal role in the confirmation of the diagnosis. However, spinal angiography remains the gold standard in the diagnosis of SDAVF. Classic angiographic findings of SDAVF are early filling of radicular veins, delayed venous return, and an extensive network of dilated perimedullary venous plexus...

The occurrence of multiple spinal dural arteriovenous fistulas (AVFs) is rare. The majority of cases reported are synchronous and the lesions are mainly found at different spinal levels. Metachronous AVFs have been defined as lesions that manifest in a temporal sequence after treatment of a first AVF. In this report, we present two distinct cases of multiple spinal AVFs. Also, we review the main features of the cases previously reported, with emphasis on the proposed theories for the origin of multiple AVFs...

Pediatric central nervous system (CNS) vascular anomalies include lesions found only in the pediatric population and also the full gamut of vascular lesions found in adults. Pediatric-specific lesions discussed here include infantile hemangioma, vein of Galen malformation and dural sinus malformation. Some CNS vascular lesions that occur in adults, such as arteriovenous malformation, have somewhat distinct manifestations in children, and those are also discussed. Additionally, children with CNS vascular malformations often have associated broader vascular conditions, e...

BACKGROUND: The lateral mesencephalic vein (LMV) represents an important connection between the infratentorial and supratentorial compartments. It joins the basal vein of Rosenthal and the petrosal system. In our experience with management of tentorial dural arteriovenous fistulas (DAVFs) we have often noted involvement of the lateral mesencephalic vein (LMV) in the venous drainage of these fistulas. METHODS: We reviewed the clinical and angiographic findings of 26 patients with tentorial DAVFs to study the incidence and pattern of drainage through the LMV...

PURPOSE: To describe the use of Embozene microspheres as an alternative treatment for intracranial dural arteriovenous fistulas (DAVF). CASE REPORT: The DAVF was located close to the vertex and mainly fed by the left medial meningeal artery (MMA). Embolization was performed using Embozene microspheres due to stenosis in the posterior branch of the left MMA and a conglomerate of tortuous courses in the anterior branch. Complete occlusion was achieved without complication...

Intracranial arteriovenous malformations are infrequent. Advances in endovascular treatment techniques have promoted the use of endovascular embolization in management of intracranial arteriovenous malformations. Transvenous or transarterial embolization procedures are effective options in the treatment of the arteriovenous fistulas. However, complications such as cranial nerve palsies may occur. Here, we present a case of right-sided lower motor neuron facial paralysis due to embolization of an intracranial dural arteriovenous fistula that have presented with clinical findings on the left eye...

OBJECTIVE: Cribriform plate dural arteriovenous fistula (dAVF) is a rare pathology, for which the treatment of choice used to be neurosurgery. Technological advances in micro-catheters and embolic agents permitted new endovascular alternatives. METHODS: We included all patients treated endovascularly for a cribriform plate dAVF between 2008 and 2013. We retrospectively analysed data focusing on the type of treatment chosen. RESULTS: Ten patients were treated by endovascular approach, with a need for an additional surgical exclusion of the fistula in two cases...

We report a rare case of a cervical spinal dural arteriovenous fistula(AVF)at the C2 level presenting with subarachnoid hemorrhage(SAH)due to a ruptured anterior spinal artery aneurysm. A 61-year-old man presented with sudden onset headache. Initial computed tomography revealed SAH around the brainstem. Digital subtraction angiography(DSA)demonstrated a cervical dural AVF that was fed by the left C1 radicular, left C2 radicular, and anterior spinal arteries, and drained into the epidural plexus. An aneurysm in the branch of the cervical anterior spinal artery was considered the bleeding point...

BACKGROUND AND PURPOSE: Tentorial dural arteriovenous fistulas are characterized by a high hemorrhagic risk. We evaluated trends in outcomes and management of tentorial dural arteriovenous fistulas and performed a meta-analysis evaluating clinical and angiographic outcomes by treatment technique. MATERIALS AND METHODS: We performed a comprehensive literature search for studies on surgical and endovascular treatment of tentorial dural arteriovenous fistulas. We compared the proportion of patients undergoing endovascular, surgical, and combined endovascular/surgical management; the proportion of patients presenting with ruptured tentorial dural arteriovenous fistulas; and proportion of patients with good neurologic outcome across 3 time periods: 1980-1995, 1996-2005, and 2006-2014...

The authors report an unusual case of a dural arteriovenous fistula (dAVF) draining only to the diploic vein and causing intracerebral hemorrhage. A 62-year-old woman presented with disturbance of consciousness and left hemiparesis. Brain CT scanning on admission showed a right frontal subcortical hemorrhage. Digital subtraction angiography revealed an arteriovenous shunt located in the region around the pterion, which connected the frontal branch of the right middle meningeal artery with the anterior temporal diploic vein and drained into cortical veins in a retrograde manner through the falcine vein...
