Giant Thoracic Spinal Arteriovenous Fistula with Cord Compression: A Case Report / 대한정형외과학회잡지

ABSTRACT

A spinal arteriovenous fistula is a rare vascular disease that is characterized by abnormal connections between the vertebral artery or its branches and the neighboring veins. Bruit and back pain are common symptoms related to the fistula. Spinal cord dysfunction can also occur as a result of blood flow steal, venous hypertension, or mechanical compression of the nerve roots and spinal cord. We report a huge arteriovenous fistula in the spinal canal at the thoracic vertebra, which was characterized by a large azygous vein connected to the epidural vein causing osteolysis on the vertebral body and spinal cord compression symptoms. Staged embolization was performed using 80 coils.
