Spinal 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 کاملDural AVF at the foramen magnum with perimedullary
perimedullary venous drainage is known to cause slowly progressive ascending myelopathy involving first the lower limbs and then the upper limbs. Often sphincter disturbances are present (1, 2). Even though it cannot provide precise location of fistula, MRI appearance is virtually pathognomonic. A swollen cord with central myelopathy and engorged perimedullary veins are indicative of the diagno...
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...
متن کاملPre- and post-treatment MR imaging and single photon emission CT in patients with dural arteriovenous fistulas and retrograde leptomeningeal venous drainage.
BACKGROUND AND PURPOSE Dural arteriovenous fistulas (DAVFs) with disturbed regional cerebral blood flow (rCBF) include retrograde leptomeningeal venous drainage (RLVD). We examined rCBF disturbances in patients with DAVFs by studying MR imaging and single photon emission CT (SPECT) changes before and after treatment. METHODS In 22 patients with DAVFs and RLVD, we studied their symptoms, pre- ...
