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...

Intraarterial digital subtraction angiography (DSA) in two patients with spinal dural arteriovenous fistulas demonstrated the major feeding arteries and the venous drainage of the respective malformations. However, the dural component of the malformations--which distinguishes them from intradural malformations--could not be recognized, nor was normal cord vasculature demonstrated. In a patient ...

IMPORTANCE Dural arteriovenous fistula is a very rare cause of myelitis that can only be treated interventionally or surgically. OBSERVATIONS A man in his 30s with paraparesis and urinary incontinence had a long-segment thoracic lesion on spinal magnetic resonance imaging. Transverse myelitis was the initial diagnosis. Although a pulse steroid and intravenous immunoglobulin treatment regimen ...

OBJECTIVES To compare the characteristics of dural arteriovenous fistulas (AVFs) with or without cerebral sinus thrombosis (CST), and to analyse the determinants of aggressive manifestations in patients with dural AVF. METHODS We investigated 69 patients aged 51.4 (SD 15) years who were diagnosed as having dural AVF. According to the location of the lesion and venous drainage pattern, dural A...

SUMMARY We report 3 patients with previously undiagnosed spinal dural arteriovenous fistulas (SDAVFs), who developed acute paraparesis following lumbar epidural steroid injection. MR imaging demonstrated spinal cord T2 hyperintensity, edema and/or enhancement of the conus, and intradural enlarged vascular flow voids. Spinal angiography confirmed SDAVFs arising from pedicles remote from the site...

Dural arteriovenous fistulas (AVFs) are uncommon, representing only 10% to 15% of all intracranial AVFs. Here we present the case of a patient with cerebral infarction who experienced a dural AVF after craniotomy for superficial temporal artery (STA) to middle cerebral artery (MCA) bypass surgery. A 48-year-old man presented with dysarthria and right side hemiparesis. A brain magnetic resonance...

The feasibility of 4D flow MR imaging to visualize flow patterns and generate relative pressure maps in the dural venous sinus in healthy subjects (n = 60) and patients with dural arteriovenous fistulas (n = 7) was investigated. Dural venous drainage was classified based on torcular Herophili anatomy by using 4D flow MR imaging-derived angiograms and magnitude images. Subjects were scanned in a...
