The anterior portion of the spinal cord is supplied by the anterior spinal artery. It begins at the foramen magnum where branches of the two vertebral arteries exit, merge, and descend along the anterior spinal cord. As the anterior spinal artery proceeds inferiorly, it receives branches originating mostly from the aorta. [1]
Vascular myelopathy (vascular disease of the spinal cord) refers to an abnormality of the spinal cord in regard to its blood supply. [1] The blood supply is complicated and supplied by two major vessel groups: the posterior spinal arteries and the anterior spinal arteries—of which the Artery of Adamkiewicz is the largest. [2]
Medial medullary syndrome, also known as inferior alternating syndrome, hypoglossal alternating hemiplegia, lower alternating hemiplegia, [1] or Dejerine syndrome, [2] is a type of alternating hemiplegia characterized by a set of clinical features resulting from occlusion of the anterior spinal artery.
This occurs when the disruption of the anterior spinal artery is at the level of the spinal cord. Contrast this with medial medullary syndrome, when the anterior spinal artery is occluded at the level of the medulla oblongata. [citation needed] Disruption of its perforating branches (sulcal artery) can result in a hemicord syndrome.
Spinal cord stroke is a rare type of stroke with compromised blood flow to any region of spinal cord owing to occlusion or bleeding, leading to irreversible neuronal death. [1] It can be classified into two types, ischaemia and haemorrhage, in which the former accounts for 86% of all cases, a pattern similar to cerebral stroke.
The artery provides blood supply to the front two-thirds of the lumbar and sacral cord. [13] When damaged or obstructed, it can result in a syndrome of spinal cord ischemia, similar to anterior spinal artery syndrome, [14] with loss of urinary and fecal continence and impaired motor function of the legs; sensory function is often preserved to a ...
Dejerine-Roussy is a rare pain syndrome. Individuals with emerging Dejerine–Roussy syndrome usually report they are experiencing unusual pain or sensitivity that can be allodynic in nature or triggered by seemingly unrelated stimuli (sounds, tastes). Symptoms are typically lateralized and may include vision loss or loss of balance (position ...
The syndrome occurs due to occlusion of perforating branches of the basilar and anterior inferior cerebellar (AICA) arteries. [ 5 ] [ 6 ] [ 7 ] It can also be caused by an interruption to the blood supply of the anterior inferior cerebellar artery or circumferential arteries .
