Cerebral arteriovenous fistulas induced by dural arteriovenous shunts.
Dural arteriovenous shunts and pial arteriovenous fistulas are uncommonly associated. Their etiology, pathogenesis, and natural history are still unclear and are likely different. We present three cases of high-flow dural arteriovenous shunts associated with pial arteriovenous fistulas and discuss their pathogenesis, anatomic association, and angioarchitecture. We propose that venous steal effe...
متن کاملSpinal dural arteriovenous fistulas.
Spinal dural arteriovenous (AV) fistulas are the most commonly encountered vascular malformation of the spinal cord and a treatable cause for progressive para- or tetraplegia. They most commonly affect elderly men and are classically found in the thoracolumbar region. The AV shunt is located inside the dura mater close to the spinal nerve root where the arterial blood from a radiculomeningeal a...
متن کاملMultiple dural arteriovenous fistulas.
Four patients with multiple intracranial dural arteriovenous fistulas (DAVFs) at separate sites were treated by endovascular techniques (transarterial and/or transvenous embolization), surgery (excision or isolation), radiotherapy, or combinations, according to the pathophysiological condition. All lesions in two patients were obliterated completely without neurological deficit. There were resi...
متن کاملValue and limitations of contrast-enhanced MR angiography in spinal arteriovenous malformations and dural arteriovenous fistulas.
BACKGROUND AND PURPOSE The purpose of this work was to study the validity of MR angiography (MRA) for identification of spinal arteriovenous (AV) abnormalities. MATERIALS AND METHODS Thirty-four consecutive patients with suspicion of spinal vascular abnormalities underwent digital subtraction angiography (DSA) after MRA. The level and side of the suspected spinal dural arteriovenous fistula (...
متن کاملDevelopment of sigmoid dural arteriovenous fistulas after transvenous embolization of cavernous dural arteriovenous fistulas.
A 54-year-old woman presented with left proptosis, chemosis, ophthalmoplegia, and tinnitus in March 1989. Angiography demonstrated a left cavernous DA VF. The feeding arteries from the left external carotid artery were embolized. Her symptoms were relieved for a while but soon recurred . On May 2, she was referred to us for treatment. Angiography revealed that all the branches of the left exter...
