BACKGROUND: Dural arteriovenous fistula (DAVF) with cortical venous drainage (CVD) are known to be aggressive in clinical course and are usually managed promptly. Spontaneous resolution of DAVF is a rare phenomenon and usually occurs in benign type of fistulas. Spontaneous thrombosis of aggressive DAVF is an extremely rare occurrence. The present study aims to identify the incidence and factors determining spontaneous resolution of aggressive DAVF. METHODS: All the patients presenting to our institution with suspected DAVF during the study period (July 2013 - December 2015) were prospectively enrolled into a database...

BACKGROUND AND PURPOSE: 4D DSA allows acquisition of time-resolved 3D reconstructions of cerebral vessels by using C-arm conebeam CT systems. The aim of our study was to evaluate this new method by qualitative and quantitative means. MATERIALS AND METHODS: 2D and 4D DSA datasets were acquired in patients presenting with AVMs, dural arteriovenous fistulas, and cerebral aneurysms. 4D DSA was compared with 2D DSA in a consensus reading of qualitative and quantitative parameters of AVMs (eg, location, feeder, associated aneurysms, nidus size, drainage, Martin-Spetzler Score), dural arteriovenous fistulas (eg, fistulous point, main feeder, diameter of the main feeder, drainage), and cerebral aneurysms (location, neck configuration, aneurysmal size)...

BACKGROUND: Patients with cavernous sinus dural arteriovenous fistulas (CS dAVFs) with cortical venous varix are indicated for aggressive treatment because of the associated risk for intracranial hemorrhage. CASE DESCRIPTION: We present a case of surgical transvenous embolization in an 84-year-old woman with CS dAVF who presented with massive intracerebral hematoma. Cerebral angiograms revealed the dural AVF drained only into the superficial middle cerebral vein...

BACKGROUND: Sacral epidural arteriovenous fistulas (eAVFs) are rare and often misdiagnosed because of the incongruence between the thoracic level of clinical deficits and the sacral location of the offending pathology. Failure to diagnose this lesion delays treatment, resulting in prolonged venous hypertension in the cord, progressive neurological deterioration, and decreased chances of recovery. METHODS: A single-institution case series and the published literature were reviewed...

Dementia is a chronic loss of neurocognitive function that is progressive and irreversible. Although rare, dural arteriovenous fistulas (DAVFs) could present with a rapid decline in neurocognitive function with or without Parkinson-like symptoms. DAVFs represent a potentially treatable and reversible cause of dementia. Here, we report the case of an elderly woman diagnosed with a DAVF after presenting with new-onset seizures, deteriorating neurocognitive function, and Parkinson-like symptoms.

BACKGROUND: To assess the efficacy of stereotactic radiosurgery (SRS) for intracranial dural arteriovenous fistulas (DAVFs), the authors retrospectively reviewed our 7-year experience. We evaluated the obliteration rate, improvement in clinical symptoms, and complications. METHODS: Thirty patients with DAVF underwent SRS using a Gamma Knife between 2009 and 2015. Twenty-three patients were treated with SRS alone, and seven patients underwent SRS for residual or recurrent DAVFs after embolization or surgery...

BACKGROUND: Localization of the arteriovenous fistula (AVF) is a crucial step in the diagnosis and treatment of spinal vascular malformations (VMs). Non-invasive angiographic techniques such as dynamic magnetic resonance angiography (MRA) and 3-dimensional computed tomography angiography (3D-CTA) have been used as standard modalities to localize AVF. With the increasing prevalence of high-spec CT scanner, 4D-CTA is being increasingly utilized in the evaluation of cerebrovascular disorders...

A 43-year-old male presented with daytime sleepiness at work and indifferent behavior like never before. Two weeks prior to hospital admission, he had episodic memory loss with well preserved remote memory. Brain MRI showed a dural arteriovenous fistula (DAVF) in the right lateral transverse sinus with a bilateral thalamic venous infarction. Cerebral angiography confirmed a right transverse sigmoid dural arteriovenous fistula with a feeding artery of the right occipital artery and left posterior meningeal artery...

BACKGROUND: Intraoperative microscopic fluorescence angiography using indocyanine green (ICG) provides visual information on real-time blood flow. However, this method cannot be applied for lesions that are not visible under microscopic imaging because excitation light does not reach the targeted vascular structures. Endoscope-integrated ICG video-angiography has recently been advocated to compensate for this limitation. This is the first reported case of a spinal arteriovenous malformation in which endoscope-integrated ICG video-angiography was successfully used...

Background Loeys-Dietz syndrome (LDS) is a recently recognized autosomal dominant connective tissue disease. The manifestations of LDS include vascular tortuosity, scoliosis, craniosynostosis, aneurysm and aortic dissections. Clinical presentation A 35-year-old woman treated with Stanford type B aortic dissection and breast cancer was referred to us for Borden type II dural arteriovenous fistula (dAVF) draining to the vein of Galen, involving the midline of tentorium cerebelli. The dAVF was treated successfully by combined transarterial and transvenous embolization...

A 58-year-old man presented with slowly progressive chemosis, exophthalmos, and blepharedema of the left eye. Digital subtraction angiography revealed multiple dural arteriovenous fistulas(dAVFs)involving the bilateral tentorium, superior sagittal sinus, and right frontal convexity. In addition, occlusion of the left cavernous sinus and left sigmoid sinus were observed, which could lead to venous hypertension and might be associated with the occurrence of multiple dAVFs. Along with the congestion of the left ophthalmic vein, increased intracranial pressure due to the left tentorial dAVF with cortical venous reflux could have caused the left eye symptoms; therefore, the tentorial lesion was treated first...

We report three cases in which carotid ultrasonography was useful for the diagnosis of dural arteriovenous fistula (dAVF). In all cases, dAVFs were fed by branches of the external carotid artery (ECA) and had retrograde leptomeningeal venous drainage. Carotid ultrasonography revealed high end-diastolic ratio (ED ratio) of the common carotid artery (CCA) (1.49-2.16) and low resistance index (RI) of the ECA (0.59-0.66). They were normalized after endovascular treatment (ED ratio of CCA 1.02-1.06, RI of ECA 0...

The authors report a case of a developmentally normal child with a congenital complex torcular dural arteriovenous fistula (DAVF) who later, in his teenage years, developed several vermian cavernomas within a large cerebellar developmental venous anomaly (DVA). The patient had initially presented with an abnormally large head circumference but no neurological deficits. He underwent several partial embolization procedures in an attempt to decrease the blood supply of the fistula over the course of 8 years. Nine years following initial presentation, he presented with a fourth ventricular hemorrhage, due to development of a new vermian cavernoma adjacent to a previously known vermian DVA and suffered subsequent mild left-sided hemiataxia from which he later recovered...

Hoarseness secondary to an anterior condylar confluence (ACC) dural arteriovenous fistula (DAVF) has not been previously described. We present a 58-year-old patient with a 3-week history of progressive unilateral left-sided headaches and hoarseness. Nasolaryngoscopy and CT neck showed the presence of unilateral vocal cord palsy with no identifiable cause along the expected course of the recurrent laryngeal nerve. MRI revealed an incidental finding of abnormal serpiginous vessels in the left hypoglossal canal which led to a diagnostic cerebral angiogram, confirming the presence of an ACC DAVF...
