Isolated intraventricular hemorrhage due to dural arteriovenous fistula (dAVF) is extremely rare and has been reported only a few times in the literature. The pathophysiological cause of isolated intraventricular hemorrhage in these cases was hypothetically attributed to retrograde venous flow into subependymal vessels, although none of these cases demonstrated radiographic evidence of such reflux. We present the first case of a dAVF with radiographic evidence of severe cortical venous reflux into the subependymal venous network causing isolated intraventricular hemorrhage, thus lending proof for the underlying pathophysiology...

PURPOSE: Although involvement of the osseous component with an anterior condylar dural arteriovenous fistula (AC-DAVF) has been frequently described, osseous venous structures in which AC-DAVFs develop have not been fully elucidated. We investigated osseous venous structures adjacent to the hypoglossal canal in normal controls and patients with AC-DAVFs. METHODS: The study included 50 individuals with unruptured aneurysms as normal controls and seven patients with AC-DAVFs...

Dural arteriovenous fistulas (DAVF) involving the anterior and posterior condylar vein at the skull base are rare but important to recognize. Due to the highly variable anatomy of the venous system of the skull base, detailed anatomical knowledge is essential for correct diagnosis and appropriate treatment of these lesions. In this report we review the normal anatomy of the condylar veins and describe rare and, to our knowledge, not previously reported anatomical variants. We also highlight the treatment modalities for these lesions with focus on the endovascular transvenous occlusion based on four consecutive cases from our center...

Intracranial multiple dural arteriovenous fistulas (MDAVFs) are rare lesions that are difficult to treat. The key factors involved in the development of MDAVFs remain unknown. At present, the majority of reports on intracranial MDAVFs are confined to case reports and small case series, and thus understanding of MDAVFs is limited. The current review assesses the available literature to date with the aim of reviewing the progress in research on intracranial MDAVFs. Intracranial MDAVFs may be divided into two types: Synchronous and metachronous...

Cranial dural arteriovenous fistulae (dAVFs) are complex vascular lesions, rarely encountered within the pediatric population. Endovascular embolization has revolutionized the management of these lesions and should be regarded as the first-line treatment for the majority of dAVFs; however, in a subset of particularly complicated lesions, traditional routes of access either do not exist or have been eliminated in the course of prior embolization attempts. We describe the case of an 11-year-old boy with a complicated torcular dAVF refractory to multiple attempts at standard endovascular treatment...

BACKGROUND AND PURPOSE: Transarterial Onyx embolization is an effective treatment for patients with intracranial dural arteriovenous fistula (DAVF). A study was performed to determine whether the clinical and radiological outcomes after transarterial Onyx treatment were affected by the type of cortical venous drainage (direct vs indirect) of high-grade DAVF. MATERIALS AND METHODS: Between May 2006 and December 2014, demographic data, clinical presentation, angiographic characteristics, and treatment-related outcomes were collected for 54 patients divided into two groups (intracranial DAVF with direct and indirect cortical venous drainage)...

BACKGROUND: Spinal cord arteriovenous shunts (scAVSs) are a group of lesions located in the spinal cord itself or in the surrounding structures. The most common scAVSs are spinal dural arteriovenous fistulas (sDAVFs), which are acquired lesions. The pathogenesis of sDAVFs involves thrombosis and venous hypertension as trigger factors. Intradural scAVSs such as spinal cord arteriovenous nidus type malformations (AVMs) and pial arteriovenous fistulas are less common than sDAVFs and are considered to have a so-called 'congenital' origin...

BACKGROUND: Onyx is important embolic material in the endovascular treatment of intracranial dural arteriovenous fistula (DAVF). However, its impact on DAVF occlusion rates, morbidity, mortality, and complication rates is not fully examined. OBJECTIVE: To improve understanding of safety and effectiveness profiles associated with transarterial endovascular treatment using Onyx for intracranial DAVF. METHODS: We analyzed data from our prospective clinical registry and conducted a systematic review of all previous transarterial embolization studies using Onyx published between January 2005 and December 2015 in MEDLINE and EMBASE...

Jiali Pu, Xiaoli Si, Rong Ye, Baorong Zhang
RATIONALE: A dural arteriovenous fistula (DAVF) refers to an abnormal direct connection between an intracranial artery and a dural venous sinus. A DAVF presenting with parkinsonism is rare, and is therefore easily misdiagnosed. Therefore, early consideration of DAVF in the differential diagnosis of reversible parkinsonism is necessary. PATIENT CONCERNS: We present the case of a 51-year-old male with progressive parkinsonism. DIAGNOSES: He was diagnosed as straight sinus occlusion...

OBJECTIVE The rarity of cerebral dural arteriovenous fistulas (dAVFs) has precluded analysis of their natural history across large cohorts. Investigators from a considerable proportion of the few reports that do exist have evaluated heterogeneous groups of untreated and partially treated lesions. In the present study, the authors exclusively evaluated the untreated course of dAVFs across a multi-institutional data set to delineate demographic, angiographic, and natural history data. METHODS A multi-institutional database of dAVFs was queried for demographic and angiographic data as well as untreated disease course...

BACKGROUND AND PURPOSE: Type I and IIa dural arteriovenous fistulas (DAVFs) have a low hemorrhagic risk, but are often the cause of debilitating tinnitus that requires treatment. While Onyx® and PHIL™ (Precipitating hydrophobic injectable liquid) transarterial embolization represent the first endovascular option, there are occasional cases where performing angioplasty and stenting of the affected sinus may lead to satisfactory results. MATERIAL AND METHODS: We retrospectively analyzed four consecutive cases of patients with DAVF-induced pulsatile tinnitus secondary to type I and II DAVFs who were treated with angioplasty and stenting of the sinus only...

A 63-year-old man developed vomiting, paraparesis, dysuria, bulbar palsy, and orthostatic hypotension over a period of 5 months. Neuroradiological examinations showed a swollen lower brainstem with a dural arteriovenous fistula at the craniocervical junction (DAVF-CCJ). A steroid was administered intravenously in the hospital to relieve brainstem edema. A few hours later, however, the patient developed acute tetraparesis with respiratory failure. Recently, there have been several reports describing the acute worsening of paraparesis in patients with a spinal dural arteriovenous fistula after steroid treatment...

Background: Dural arteriovenous fistulas (DAVF) are unusual intracranial vascular malformations consisting of anomalous connections between meningeal arteries and dural sinuses or the veins that pass through them. They have variable clinical presentation and prognosis, which depend on their location and venous hemodynamics. Treatment is based on the closure of the abnormal connections, which is usually conducted via arterial and/or transvenous endovascular techniques. Case Description: We present a male patient who complained of headaches and left-sided pulsatile tinnitus due to DAVF from the external carotid artery branches draining directly into the ipsilateral sigmoid sinus...
