Spinal Angiogram – This exam is the gold standard for confirming the presence of a spinal vascular malformation, diagnosing the type of malformation (Types I – IV) and The disruption of vessels leads to intraparenchymal hemorrhage; the disruption of the blood-spinal cord barrier, which is closely associated with edema formation; the release of vasoactive molecules that influence the extent of spinal cord perfusion; and the loss of autoregulation. 33 Together, these vascular events result in varying degrees of spinal cord ischemia. Ischemia not only results in the death of cells but also triggers a cascade of secondary events, including excitotoxicity, that sparse, especially in the lower segments. The midthoracic spinal cord is supplied by terminal vessels descending from the subclavian and vertebral arteries or ascending from the abdominal aorta; this watershed is particularly vulnerable to vascular insufficiency, and spinal cord infarction is most likely to occur at T-4 to T-9. Vascular Insults: Hemorrhage and Ischemia–Reperfusion As alluded to previously, vascular insult has delete-riouseffectsonthespinalcord,bothinitiallyatthetime ofinjuryandsubsequenttothis.Thesevascularinjuries produce both hemorrhagic and ischemic damage.

Arterial supply The spinal cord is supplied by three longitudinal arteries: single anterior spinal artery: supplies the anterior Ischemic reperfusion injury (IRI) of the spinal cord occurs due to temporary interruption of the blood supply to the spinal cord. This may result in irreversible vascular injuries with subsequent paraplegia or other neurological deficits . This serious complication is frequently seen in transient ischemic insults of the spinal cord and after Cord ischemia, primarily secondary to vascular insults in the mid-thoracic region, is common as the diameter of the spinal cord and its resulting arteries undergo significant narrowing here. Damage of any kind to the anterior spinal artery can cause significant motor symptoms, as it supplies the anterior two-thirds of the spinal cord. Rather, the spinal cord remains intact and the neurological damage is due to secondary vascular and pathogenic events, including oedema, inflammation and changes to the blood-spinal cord barrier.

A disruption in the blood supply can cause injury or damage to tissues and can block messages (nerve impulses) travelling along the spinal cord. The pathobiology of SCI involves a primary mechanical insult to the spinal cord and activation of a delayed secondary cascade of events, which ultimately causes progressive degeneration of the spinal cord. spinal cord blood flow and spinal cord-blood barrier integrity in the evolution of delayed neurological deterioration after transient spinal cord ischemia in rabbits. Methods: Anesthetized rabbits were subjected to lumbar spinal cord ischemia (25 minutes) and variable periods of reperfusion (30 minutes to 48 hours after ischemia). Spinal cord injuries may be primary or secondary :. Primary injuries arise from a variety of mechanisms, including mechanical disruption, transection, penetrating injuries due to bullets or weapons, vertebral fracture/subluxation or displaced bony fragments causing penetrating spinal cord and/or segmental spinal nerve injuries.

The term includes both ischemic and hemorrhagic incident. Most spinal vascular lesions are characterized by an abnormal arteriovenous shunt, which may be located within the dura, on the spinal cord surface, within the substance of the spinal cord, or rarely extradurally. 2 – 5 The shunt may take the form of a simple direct arteriovenous fistula (AVF) or of a more complex nidus of dysmorphic arteries and veins without an intervening capillary bed. To draw awareness to a rarely described complication with potential to add devastating neurological insult to the original spinal cord injury, and to discuss evidence supporting a vascular Vascular malformations and hemangiomas of the canine spinal cord. Cordy DR. An arteriovenous malformation and two hemangiomas in the canine spinal cord were found in three dogs.
