Anterior Spinal Artery Syndrome

Anterior spinal artery syndrome is a condition in which blood flow through the anterior spinal artery is impaired. It can be brought on by a variety of causes and affects both sensory awareness and strength.

  1. Causes

    • The causes of anterior spinal artery syndrome may include arteriosclerosis (buildup in the artery that obstructs blood flow), trauma, surgery, vasculitis (inflammation of the blood vessels), compression and infections.

    Symptoms

    • The symptoms generally include a loss of pain sensation below the point of reduced blood flow, muscular weakness in the limbs and problems with bladder control. Sensation of vibration is usually retained.

    Diagnosis

    • Diagnosis is generally achieved via ruling out other causes (diagnosis by exclusion). However, the "American Journal of Neuroradiology" reports that a magnetic resonance imaging (MRI) scan may provide some information.

    Treatment

    • There is no standard treatment protocol for anterior spinal artery syndrome, though individual treatment options may be generated dependent on the root cause.

    Long-Term

    • Long-term outcomes for anterior spinal artery syndrome are generally poor, with little or no recovery in the majority of cases.
