Ventral cord syndrome
Updates to Article Attributes
AnteriorVentral cord syndrome (also known as Beck'santerior cord syndrome or ) is one of the incomplete cord syndromes and affects the anterior parts of the cord resulting in a pattern of neurological dysfunction dominated by motor paralysis and loss of pain, temperature and autonomic function. Anterior spinal artery ischaemia is the most common cause.
Terminology
Ventral cord syndrome encompasses all causes of damage to the anterior spinal cord regardless of aetiology (see below). In contrast, aanteriornterior spinal artery syndrome) is, also known as Beck's syndrome, denotes a clinical subset of spinalventral cord injury syndromes,syndrome specifically due to ischaemia/infarction of the anterior two-thirds of the spinal cord, typically sparing due to involvement of the posterior thirdanterior spinal artery.
Clinical presentation
Patient presents with the following features:
- complete motor paralysis below the level of the lesion due to involvement of the corticospinal tracts
- loss of pain and temperature at and below the level of injury due to involvement of lateral spinothalamic tract
- intact 2-point discrimination, proprioception and vibratory senses due to intact posterior column
- autonomic dysfunction: orthostatic hypotension
- bladder and bowel dysfunction and sexual dysfunction may arise depending on the level of the lesion
Pathology
Anterior cord syndrome is caused by ischaemic injury to the anterior aspect of spinal cord due to occlusion of anterior spinal artery, which most commonly occurs as a consequence of non-traumatic processes, although it may be traumatic. The anterior two-thirds of the spinal cord contains corticospinal and spinothalamic tracts, which are affected in this syndrome.
Causes of anterior spinal artery occlusion include:
- atherosclerosis
- aortic pathology
- aortic aneurysm
- aortic thrombosis
- aortic dissection
- aortic surgery/intervention
- external compression
- herniated disc
- neoplastic mass
- posterior osteophyte
- kyphoscoliosis
- trauma: direct stab injuries
Treatment and prognosis
Prognosis of anterior cord syndrome is worst among all other spinal cord injury syndromes. It is associated with high mortality and poor functional outcome in terms of poor recovery of motor power and coordination.
Treatment is focused on treating the primary cause of anterior spinal artery insufficiency and general supportive treatment and care.
History and etymology
The anterior cord syndrome is thought to have been initially described Schneider in 1955 in the English literature ref although there are reports of this being described by K Beck in German literature in 1952 4.
