Key Points about Anterior Spinal Artery Syndrome
- Definition: Anterior spinal artery syndrome (ASAS) occurs due to ischemia of the anterior portion of the spinal cord, leading to motor dysfunction, loss of pain and temperature sensation, while preserving proprioception and vibration sensation.
- Causes: Common causes include atherosclerosis, trauma, surgical complications, and aortic dissection. Hypotension and embolism may also precipitate this condition.
- Symptoms: Symptoms include sudden onset of weakness, particularly affecting the legs, loss of pain and temperature sensation below the level of the lesion, and urinary retention. Sensory modalities like proprioception and vibration remain intact.
- Diagnosis: Diagnosis is clinical, supported by MRI of the spinal cord showing ischemic changes in the anterior part of the spinal cord. Spinal angiography may be used to identify vascular issues.
- Management: Immediate management involves stabilising the patient, addressing the underlying cause, and using neuroprotective strategies such as avoiding hypotension. Long-term rehabilitation may be required for motor and sensory deficits.
- Complications: Complications include permanent neurological deficits, chronic pain, spasticity, and issues with bowel and bladder function if not treated promptly.
