| Sumario: | Spinal epidural arteriovenous fistulas (SEDAVFs) are rare spinal vascular malformations that
are difficult to diagnose and treat. SEDAVFs can be asymptomatic; however, symptoms can
arise from the compression of adjacent nerve roots by dilated vein and perimedullary venous
reflux, caused by shunting into the epidural venous plexus. A 31-year-old male presented to our
institution with a 2-year history of progressively worsening low-back pain, radiating thigh pain,
and sensory changes in his lower extremities. MRI and CT angiography demonstrated dilated
epidural vascular lesion compressing the nerve root. The SEDAVF was embolized with multiple
coils, which alleviated the nerve root compression from the engorged venous varix and improved
the patient’s radiculopathy. Our experience from this case shows that endovascular coil
embolization using the transarterial approach can be an effective treatment for SEDAVF and an
alternative to surgical ligations. |
