Spinal cord infarction

Spinal cord infarction starts as a stroke. Spinal cord symptoms often peak in a few minutes or hours. Anterior spinal cord artery syndrome occurs due to different occluded blood supply arteries, mostly in the middle thoracic segment or lower thoracic segment. The initial symptoms are often sudden root pain or diffuse pain in the corresponding part of the lesion level, delayed paralysis in a short time, and spastic paralysis after spinal cord shock; Conduction bundle type dissociative sensory disorder, loss of pain and temperature sensation and deep sensory retention (posterior cord not involved), urinary and fecal disorder is more obvious; Posterior spinal artery syndrome, the posterior spinal artery is rarely occluded. Even if it occurs, the symptoms are mild and recover quickly due to good collateral circulation; It shows acute root pain, deep sensory loss and sensory ataxia below the lesion level, pain warmth and muscle strength preservation, and sphincter function is often not affected; Central artery syndrome, lower motor neuron paralysis, decreased muscle tone and muscle atrophy at the corresponding stage of lesion level, mostly without sensory impairment and pyramidal tract damage.
