ABSTRACT

The purpose of this video is to introduce digital subtraction myelography for CSF-venous fistula (CVF) detectection.1⇓-3 CVF is the most recently identified and likely the most prevalent type of spinal CSF leak that leads to spontaneous intracranial hypotension4,5 CVFs are occult on conventional MRI and CT, necessitating the use of myelography for the diagnosis. This video highlights one such technique, which is important because an increasing number of centers are starting to diagnose CVF.
