Posterior Spinal Artery Syndrome is a rare neurological condition that results from the occlusion of the Posterior spinal artery. This artery supplies blood to the posterior one-third of the Spinal cord, including the dorsal columns and lateral corticospinal tracts.
Etiology[edit]
The syndrome is often caused by a blockage in the blood vessels that supply the posterior spinal artery. This can occur due to a variety of reasons, including Atherosclerosis, Thrombosis, Embolism, or Vasculitis. In some cases, it can also be caused by surgical complications or traumatic injury to the spine.
Clinical Features[edit]
Patients with Posterior Spinal Artery Syndrome typically present with a sudden onset of symptoms. These can include:
- Sensory loss below the level of the lesion, particularly loss of proprioception and vibration sense.
- Motor weakness or paralysis, due to involvement of the lateral corticospinal tracts.
- Pain and temperature sensation are usually preserved, as these are carried by the anterior spinal cord.
Diagnosis[edit]
Diagnosis of Posterior Spinal Artery Syndrome is typically made based on the clinical presentation and imaging studies. MRI is the imaging modality of choice, as it can clearly show the area of the spinal cord that is affected.
Treatment[edit]
Treatment of Posterior Spinal Artery Syndrome is primarily supportive. This can include physiotherapy to help manage motor weakness, and pain management strategies. In some cases, surgical intervention may be required to remove the cause of the blockage.
Prognosis[edit]
The prognosis for Posterior Spinal Artery Syndrome varies depending on the severity of the condition and the patient's overall health. Some patients may experience a full recovery, while others may have long-term sensory and motor deficits.
