Untreated, spinal arteriovenous malformations can lead to progressive disability. Specific complications may include:
April 25, 2014
- Problems with moving (motor deficits)
- Pain, tingling and numbness (sensory deficits)
- Spinal column deformity
- Bulging blood vessel (aneurysm)
- High blood pressure in the veins (venous hypertension), which can cause fluid accumulation (edema) and tissue death due to lack of oxygen (spinal cord infarction)
- Hemorrhage, which can accelerate spinal cord damage
