Spinal Vascular interventions

Spinal vascular malformations encompass a range of disorders that often result in an intermittent or progressive myelopathy. Standard magnetic resonance imaging (MRI) may not identify the vascular abnormality and can be normal in the early stages of the disorder. The myelopathy can be exercise dependent initially and can spontaneously remit.

However, if not identified, it can lead to a progressive disabling myelopathy, which is difficult to reverse even after correction of the spinal vascular abnormality. A negative formal spinal angiogram does not completely exclude a spinal vascular malformation, as there is a large range of abnormalities that extend throughout the length of the spine and beyond into the cerebral vasculature and pelvic vasculature.
