Spinal Cord Disease
Published in Philip B. Gorelick, Fernando D. Testai, Graeme J. Hankey, Joanna M. Wardlaw, Hankey's Clinical Neurology, 2020
Posterior spinal artery syndrome: Rare.Dorsal column (discriminating touch) impairment with sparing of strength (corticospinal tracts), pain/temperature sensation (spinothalamic tracts), and deep tendon reflexes (anterior horn cells unaffected).
Spinal Cord Angiography

The next feature of importance to the spinal cord blood circulation is its rather strict division into the anterior and posterior spinal artery territories, the first representing about two thirds, and the latter one third, of the cross section of the spinal cord. The longitudinal arterial system is, thus, dominated by the role of the anterior spinal artery. The blood flow is directed in the anterior aspect of the cord downwards in the cervical, distal thoracic, and lumbosacral regions, but upwards from the point of junction of the Adamkiewicz artery to the second dorsal segment. There is no significant anastomotic network encircling the spinal cord that connects the anterior and the two posterior spinal arteries, except at their distal portion around the cauda equina.81

Ischemic spinal cord injury (ISCI), also called spinal cord infarction, usually develops from acute occlusion of anterior and posterior spinal arteries, and account for 0.3–1% of all infarctions.1,2 Although ISCI is frequently caused by complications of aortic surgery, many of them occur spontaneously in clinical settings.3–5 ISCI is characterized by sudden onset and rapid progression of symptoms. Clinical manifestation of ISCI is defined by the vascular territory of the artery involved. Anterior spinal artery syndrome is characterized by severe sharp pain, paralysis, loss of sphincter control, and deficit of thermal sense with relative preservation of position and vibratory sense. Conversely, posterior spinal artery syndrome is characterized by a significant loss of proprioception and vibratory sense and less severe weakness.6

The etiology of PCS, in this study, was most often related to spinal cord tumors as mentioned, however, we also noted cases associated with spinal stenosis and with epidural abscess. In each of these cases, it is suspected that SCI was caused by these nearby masses compressing the posterior aspect of the spinal cord with resultant cord edema or occlusion of the posterior spinal artery (PSA). Prior literature has noted PCS to be linked with a variety of causes17–21 where interruption of PSA blood flow is often seen. The PSA supply the posterior 20–30% of the spinal cord, including the posterior columns, the posterior aspect of the dorsal horns, and a border zone partially involving the corticospinal and anterolateral tracts. The anatomy of the vasculature accounts for the profound proprioceptive deficits and the variation in weakness and sensory loss typically seen in PCS.22
