All the related sensory sparing arise due to incomplete lesion development at the anterior spinal cord. This injury results in weakness in the arms more so than the legs. It is the most common neurological complication occurring following abdominal aortic surgery with an incidence of 0.1-0.2%. The diagnosis usually is made on the basis of clinical findings because the cause of the syndrome remains obscure in most cases [2]. The motor neurones of the spinal cord are supplied by the anterior spinal artery and its sulcocommissural arteries (Fig. Both pain and temperature sensation depend upon spinothalamic tracts, whereas tactile, vibration and joint position sense are supplied by the dorsal columns. Symptoms usually occur very quickly and are often experienced within one hour of the initial damage. Lesion formation at the anterior part of the spinal cord can also arise due to infraction development. Spontaneous unruptured nondissected aortic aneurysms with intramural thrombus can rarely cause anterior cord infarctions. In contrast to a complete spinal cord injury , lesions only affect part of the cord, and patients present with a dissociated sensory loss . There is also a risk of development of autonomic dysreflexia, gait impairment, neuropathic pain, sexual dysfunction, and neurogenic bladder, bowel, and skin depending on the degree of injury. The intensity of the loss of sensory perception depends on the complexity of lesion present in the spinal cord, as well as the involvement of spinal cord1,2,3. anterior cord syndrome localized injury to the anterior portion of the spinal cord, characterized by complete paralysis and hypalgesia and hypesthesia to the level of the lesion, but with relative preservation of posterior column sensations of position and vibration. [1] Any embolus or thrombus in largest feeder vessel known as the artery of Adamkiewicz, can lead to an anterior spinal syndrome. The injury is considered “incomplete” because patients are usually not completely paralyzed. “Anterior cord syndrome results from a flexion injury, in which bone or cartilage causes damage to the anterior spinal artery or anterior aspect of the spinal cord. Affected individuals have completely defective motor functionality commences beneath the lesion formation. The mortality rate is approximately 20%, with 50% of individuals living with anterior cord syndrome having very little or no changes in symptoms. [6], The anterior portion of the spinal cord is supplied by the anterior spinal artery. Chest pain with altered ECG has been identified if infraction develops in C7 to T1 of spinal cord. Anterior cord syndrome is a type of incomplete spinal cord injury that can result in the loss of motor function or paralysis of the lower body. Anterior spinal artery syndrome (also known as "anterior spinal cord syndrome") is syndrome caused by ischemia of the anterior spinal artery, resulting in loss of function of the anterior two-thirds of the spinal cord. It begins at the foramen magnum where branches of the two vertebral arteries exit, merge, and descend along the anterior spinal cord. According to the classification made by Gloviczki et al. Anterior cord syndrome is a spinal lesion affects the anterior region of the spinal cord, which causes loss of motor control integrated with crude sensation. The region affected includes the descending corticospinal tract, ascending spinothalamic tract, and autonomic fibers. The operative intervention may conduct for repairing of an abdominal aortic aneurysm1. Less frequently, neurological damage in the spinal nerve may also a contributory factor for the development of anterior cord syndrome4. [7][8], "Anterior spinal artery syndrome and its natural history", Subacute combined degeneration of spinal cord, https://en.wikipedia.org/w/index.php?title=Anterior_spinal_artery_syndrome&oldid=991400212, Short description is different from Wikidata, Articles with unsourced statements from October 2020, Creative Commons Attribution-ShareAlike License, Anterior cord syndrome is central diagram, Autonomic dysfunction may be present and can manifest as, This page was last edited on 29 November 2020, at 21:30. The exact location of lesion development is at the anterior two-thirds of the spinal cord due to ischemic injury caused by a vascular lesion at the anterior spinal artery. The region affected includes the descending corticospinal tract, ascending spinothalamic tract, and autonomic fibers. Case report: A 42-year-old male patient who comes to the emergency department due … Hopkins syndrome - rare. Usually, accidental trauma provides compression injury or forced flexion and resultant of this lesion formation at the anterior part of the spinal cord. Of those types, anterior cord syndrome, represents less than 1% of total injuries but 89% of that small percentage are non-traumatic, according to the Journal of Spinal Cord Medicine. All these imaging tools are useful to detect the actual location of the lesion and also exclude other possibilities of spine injury7. Anterior cord syndrome is known as an “incomplete” spinal cord injury because patients may experience some function below the level of injury. [1] The anterior spinal cord is at increased risk for infarction because it is supplied by the single anterior spinal artery, which has few collateral unlike the posterior spinal cord which is supplied by two posterior spinal arteries. Causes of anterior horn syndrome include: anterior spinal artery ischemia. It is caused when the anterior spinal artery is compromised, causing restriction of blood, oxygen, glucose, etc. The brain's ability to send and receive signals to and from parts of the body below the site of injury is reduced but not entirely blocked. Central cord syndrome, anterior cord syndrome, posterior cord syndrome, and Brown-Séquard syndrome are the most common types of incomplete spinal cord syndromes. Acute spinal cord ischemia syndrome represents only 5-8% of acute myelopathies 4,5 and <1% of all strokes 7. 4). It is associated with many other disease conditions or treatment complications. Traumatic injury may occur due to road accidents because of faulty driving or uncontrolled traffic issue. It is characterized by a corresponding loss of motor function, loss of pain and temperature sensation, and hypotension. They are traumatic and non-traumatic. poliomyelitis-like syndrome. The severity of the symptoms is related to the site and degree of lesion present in the spinal cord. Central cord syndrome (CCS) is an incomplete traumatic injury to the cervical spinal cord – the portion of the spinal cord that runs through the bones of the neck. Spinal cord infarct as the initial clinical presentation of aortic dissection is a very rare finding. This is the most feared, though rare complication of bronchial artery embolization done in massive hemoptysis. Patients may require the medical device to assist their movement and activities of daily living depending upon the degree of injury, The long-term treatment and related support require for managing spasticity, mobility impairment, neuropathic pain, and neurogenic bladder, bowel, and skin. Anterior horn syndrome is a fairly generic term used to refer to flaccid paralysis and areflexia due to involvement of the anterior grey matter horns of the spinal cord. But precise diagnosis may not possible with X-ray. But effective and comprehensive rehabilitation management is the ultimate necessity of patients suffering from anterior cord syndrome. In childhood, most cases are due to trauma or cardiac malformations 5. Anterior and posterior cord syndromes The anterior spinal cord is the front section of the structure, and the posterior spinal cord is the back. Anterior spinal artery syndrome — The most common clinical presentation of a spinal cord infarction is anterior spinal artery (ASA) syndrome . This can happen as postoperative secondary complications in adults. There are two main causes involve in Anterior cord syndrome. to the spinal cord. Antenatal Screening For Syndrome Detection, Thoracic Outlet Syndrome - Symptoms, Exercises, Test, Treatment, Red Man Syndrome - Pictures, Treatment, Symptoms, Causes, SyndromesPedia – Medical Syndromes Information Portal, Posterior Reversible Encephalopathy Syndrome. Your email address will not be published. Sensation is typically preserved. However, it is possible that Anterior Cord Syndrome affected patients only involves in loss of motor function without loss of sensation. When the diagnosis of anterior cord syndrome is determined, the prognosis is unfortunate. Etiology of Incomplete Cord Syndromes. Defined as spinal cord injury with some preserved motor or sensory function below the injury level including voluntary anal contraction (sacral sparing) sacral sparing critical to separate complete vs. incomplete injury OR palpable or visible muscle contraction below injury level [1], It is also known as "Beck's syndrome". Entire spine X-ray usually conducted to locate the problem. Anterior cord syndrome of cervical spinal cord at C4 level (721384009); Anterior cord syndrome of spinal cord at fourth cervical level (721384009) Recent clinical studies. [1], Clinical features include paraparesis or quadriparesis (depending on the level of the injury) and impaired pain and temperature sensation. Anterior Cord Syndrome Anterior cord syndrome affects the front of the spinal cord. This causes paralysis of motor functions and the sensation of pain and temperature are lost” (Reed, 2001, p.541). picture known as anterior spinal artery syndrome, characterised by loss of motor function with intact or impaired sensory function. Other causes include vasculitis, polycythemia, sickle cell disease, decompression sickness, and collagen and elastin disorders. [citation needed], Due to the branches of the aorta that supply the anterior spinal artery, the most common causes are insufficiencies within the aorta. Cauda equina syndrome, which involves damage to nerve roots at the caudal end of the cord, is not a spinal cord syndrome. This syndrome was first described by Spiller in 1909. Though this has exam relevance (Question 23 from the first paper of 2018) it is in fact a very rare syndrome, appearing in 2% of patients undergoing ruptured aortic aneurysm repair, and in only 0.4% of elective AAA repairs (Gialdini, 2017). The indoor hospital service requires treating anterior cord syndrome at the initial stage. The deficits of sensory perception include loss of pinprick or temperature sensation. There are six basic types of ISCS based on clinical findings: (a) central cord syndrome (CCS), (b) Brown-Séquard syndrome, (c) ventral (anterior) cord syndrome (VCS), (d) dorsal (posterior) cord syndrome (DCS), (e) cauda equina syndrome Diffusion-weighted imaging may be used as it is able to identify the damage within a few minutes of symptomatic onset.
