Spinal arteriovenous malformation (AVM) is a rare, abnormal tangle of blood vessels on, in or near the spinal cord. Without treatment, spinal AVM can permanently damage your spinal cord.

Spinal arteriovenous malformations can be difficult to diagnose because signs and symptoms are similar to those of other spinal conditions, such as spinal dural arteriovenous fistula, spinal stenosis, multiple sclerosis or a spinal cord tumor.

Treatment

Treatment for spinal AVM may involve a combination of approaches to lessen symptoms as well as reduce the risk of potential complications. The choice of treatment will depend on the size, location and blood flow of your spinal AVM, your neurological exam, and your overall health.
The goal of spinal AVM treatment is to reduce the risk of hemorrhage and stop or prevent the progression of disability and other symptoms.
