Ischemic Stroke (Anterior Spinal Artery)

An Ischemic Stroke (Anterior Spinal Artery) occurs when blood flow to the front part of the spinal cord is blocked, causing damage to the nervous system. This condition affects the spinal cord, which is crucial for transmitting signals between the brain and the rest of the body. When the blood supply is interrupted, the spinal cord tissue can become injured, leading to symptoms like weakness, loss of sensation, and difficulty controlling muscles. The main health impact is often sudden paralysis or loss of movement below the level of the injury. This stroke type is less common than brain strokes but can cause serious disability. Early recognition of symptoms is important because the spinal cord controls many vital functions.

Ischemic Stroke (Anterior Spinal Artery) is a neurological emergency characterized by acute interruption of blood flow through the anterior spinal artery, leading to ischemia and infarction of the anterior two-thirds of the spinal cord. The primary mechanism is usually arterial occlusion due to embolism, thrombosis, or systemic hypoperfusion. This artery supplies the anterior horn cells, corticospinal tracts, and spinothalamic tracts, resulting in a characteristic clinical syndrome. Patients typically present with bilateral motor paralysis, loss of pain and temperature sensation below the lesion, and preserved dorsal column functions such as proprioception and vibration. The condition is significant because it causes sudden and often severe neurological deficits, including paraplegia or quadriplegia depending on the lesion level. Prompt diagnosis and management are critical to limit permanent disability.
