BACKGROUND AND PURPOSE Brain arteriovenous fistulas (BAVFs) are dangerous lesions with significant risks for hemorrhage and re-hemorrhage; thus, the management of BAVFs is an important subject. Flow disconnection can be accomplished by surgical or endovascular techniques. We reviewed the experience in our endovascular treatment of patients with BAVFs. MATERIALS AND METHODS From March 2006 to ...

Patients with dural arteriovenous fistulas (DAVFs) in the transverse-sigmoid sinus suffer from several symptoms: bruit, headache, visual impairment, and so on. But depression is rare in patients with DAVF. The authors reported a rare case presenting the improvement of depression after the treatment of a dural arteriovenous fistula in the left transverse-sigmoid sinus. A 46-year-old male had suf...

BACKGROUND AND PURPOSE Cases with spinal perimedullary arteriovenous fistulas (SPAVFs) or spinal dural arteriovenous fistulas (SDAVFs) at the cervicomedullary junction are rare. We performed a retrospective, angiographic study of 6 such patients to assess whether available angiographic data were predictive of the risk for hemorrhage. METHODS We report 6 patients with arteriovenous fistulas at...

Spinal dural arteriovenous fistulas (SDAVFs) represent an abnormal connection between a dural artery and an intradural radicular vein. The radicular vein drains the medullary venous plexus , which dilates in response to arterial pressure, resulting in enlarged serpiginous vessels , usually posterior to the spinal cord. This finding is not specific for SDAVF, as it can be found in most spinal ar...

Spinal vascular malformations (SVM) are rare diseases in comparison to vascular malforma‐ tions of the brain. Spinal dural arteriovenous fistulas (SDAVFs), also known as Type I spinal arteriovenous malformations, account for 70% of spinal vascular malformations, and are the most common vascular malformations of the spinal cord and its surrounding dura mater; however, they remain relatively unde...

A 74-year-old male presented with an intracranial hemorrhage caused by multiple dural arteriovenous fistulas (DAVFs) in the left transverse sinus and right sigmoid sinus. Four months previously, the patient underwent tongue cancer removal with lymph node dissection and ligation of the right internal jugular vein. Endovascular embolization (transvenous and transarterial embolization) resulted in...

Three patients are presented with slowly progressive tetraparesis caused by an intracranial dural arteriovenous fistula with exclusive perimedullary venous drainage. MR imaging showed a swollen cervicothoracic cord with central myelopathy and dilated perimedullary veins. Bilateral vertebral angiography initially failed to demonstrate the fistulas, and diagnosis was established with external car...

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 pre...
