This is a case of 62-year-old patient presenting with tingling and numbness extending from the buttocks area towards lower extremities gait instability. Contrast Magnetic Resonance Imaging (MRI) time-resolved imaging contrast kinetics (TRICKS MRI) raised suspicion for possible dural arteriovenous fistula. Diagnostic Digital Subtraction Angiography (DSA) showed filum terminale arterio venous fis...

Abstract Background Spinal dural arteriovenous fistulas (dAVF) remain a rare, diagnostically challenging and possibly correctable condition with important prognostic outcomes dependent primarily on early detection treatment. Case presentation We present case of 73-year-old male progressively worsening neurological symptoms after steroid administration for presumed diagnosis transverse myelitis....

Intraoperative angiography (IOA) is employed for the treatment of the complicated cases in neurological surgery. The IOA is usually performed with OEC portable digital subtraction angiography (DSA) unit. We are performing IOA with portable fluoroscopy unit with simple DSA function and report its usefulness on neurosurgical treatment. IOA or hybrid treatment with mobile fluoroscopy system was pe...

BACKGROUND AND PURPOSE Studies to determine the value of noninvasive neurovascular studies for the effectiveness of treatment and long-term follow-up of dural arteriovenous fistulas (AVFs) are of clinical importance. We determined whether the serial changes of carotid duplex sonography (CDS) were correlated with the evolution of dural AVF status after treatment or follow-up. METHODS Four para...

Spinal arteriovenous malformation (AVM) is a broad term that constitutes diverse vascular pathologies. To date, various classification schemes for spinal AVM have been proposed in literature, which helped neurosurgeons understand the pathophysiology of the disease and determine an optimal treatment strategy. To discuss indications and results of surgical and endovascular interventions for spina...

BACKGROUND AND PURPOSE MR imaging and contrast-enhanced MR angiography have been used to detect evidence of spinal dural arteriovenous fistulae (AVF); however, the sensitivity and specificity of these techniques have not been shown. The purpose of this study was to establish the sensitivity, specificity, and accuracy of MR imaging alone compared with MR imaging plus MR angiography in determinin...

Dural arteriovenous fistula (AVF) presenting with subdural hematoma is relatively rare. We report a case of dural AVF presenting as acute subdural hematoma (ASDH) and provide a review of the literature. A 56-year-old man presented with disturbance of consciousness. Computed tomography demonstrated a right ASDH and a small right occipital subcortical hematoma. Cerebral angiography showed a dural...

A 66-year-old woman presented with intermittent paraparesis and generalized tonic-clonic seizure. Cerebral angiography demonstrated dural arteriovenous fistula (AVF) involving superior sagittal sinus (SSS), which was associated with SSS occlusion on the posterior one third. The dural AVF was fed by bilateral middle meningeal arteries (MMAs), superficial temporal arteries (STAs) and occipital ar...

The author has encountered a 67-year-old man with dural arteriovenous fistula (AVF) presenting as a non-traumatic chronic subdural hematoma (CSDH). This previously healthy patient was hospitalized due to progressive headache with subacute onset. He underwent burr-hole surgery twice for evacuating the left CSDH that was thickest at the posterior temporal area. The operative procedure and finding...

A 41-year-old man presented with consciousness disturbance and right hemiparesis. Computed tomography showed a hematoma in the frontal lobe. Left carotid angiography showed a dural arteriovenous fistula (AVF) located in the cranial vault, supplied by the left middle meningeal artery, and drained directly into the cortical vein adjacent to the superior sagittal sinus. Emergency decompressive cra...
