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.
1989, Singer et al. 1991). However, the literature largely addresses dysraphic cord syndromes (Volpe 1995, Behrman et al. 1996) and intra-partum traumatic cord lesions (Chapman et al. 1978, Fibrocartilaginous embolism or FCE is a vascular insult to the spinal cord. This problem may cause a variety of neurological deficits. Advanced diagnostic imaging is required for definitive diagnosis.

For example, an anteroposterior compressive force on a flexible tube filled with gelatin, a physical model of the contused spinal cord, produces longitudinal stress that is most intense in the center of the tube.

Although this necrotic myelitis is attributed to venous thrombosis, there is usually no angiographic evidence of venous thrombosis or vascular spinal cord malformation.

Spinal vascular malformations, also known as spinal arteriovenous malformations (AVMs), are the result of an abnormal connection between arteries and veins that occurs within the spinal canal or spinal dural covering. The term spinal vascular malformation includes several distinct types of vascular problems under one name. by spinal cord necrosis and evidence of enlarged, tortuous, thrombosed veins.

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.

The microcirculation, especially venules and capillaries, PATHOPHYSIOLOGY OF SPINAL CORD INJURY 255 Spinal arteriovenous malformation (AVM) is a rare, abnormal tangle of blood vessels on, in or near the spinal cord. Without treatment, spinal AVM can permanently damage your spinal cord. Oxygen-rich blood normally enters your spinal cord through arteries, which branch into smaller blood vessels (capillaries).
