Purpose. The artery of Adamkiewicz (AKA) provides the major blood supply to the anterior thoracolumbar spinal cord and iatrogenic injury or inadequate reconstruction of this vessel during vascular and endovascular surgery can result in postoperative neurological deficit due to spinal cord ischemia.

What is Adamkiewicz artery?

The artery of Adamkiewicz is the dominant segmental feeding vessel to the thoracic cord, supplying the anterior aspect of the cord via the anterior spinal artery. Adamkiewicz has a characteristic hairpin turn on the cord surface as it first courses superiorly, then turns inferiorly.

What does the artery of Adamkiewicz supply?

The artery of Adamkiewicz is significant in that it is the only major arterial supply supplying the anterior spinal artery along the lower thoracic, lumbar, and sacral segments of the spinal cord.

How do you identify an Adamkiewicz artery?

The artery of Adamkiewicz most commonly arises at the level of the lower thoracic or upper lumbar vertebrae (between the T8-L1 levels in 89%, between the T7-L2 levels in 95%), with a striking left sided predominance (77%) 6. However, origins from either side and any level from T3 to L4 have been reported 6.

What is the great anterior medullary artery of Adamkiewicz?

The artery of Adamkiewicz, also known as the great anterior radiculomedullary artery or arteria radicularis anterior magna, is the name of the dominant thoracolumbar segmental medullary artery, which supplies the lower spinal cord by reinforcing the anterior spinal artery.

What level does the artery of Adamkiewicz?

Origin. The artery of Adamkiewicz most commonly arises at the level of the lower thoracic or upper lumbar vertebrae (between the T8-L1 levels in 89%, between the T7-L2 levels in 95%), with a striking left sided predominance (77%) 6. However, origins from either side and any level from T3 to L4 have been reported 6.

Where does artery of Adamkiewicz come from?

Origin. The artery of Adamkiewicz most commonly arises at the level of the lower thoracic or upper lumbar vertebrae (between the T8-L1 levels in 89%, between the T7-L2 levels in 95%), with a striking left sided predominance (77%) 6.

What is a medullary artery?

Each segmental medullary artery is a branch of the cervical part of the vertebral artery. These small branches penetrate into the vertebral bone through small openings such as the intervertebral foramina. These segmental arteries provide blood flow to the surface and inside the spinal canal at each segmental level.

What happens if the anterior spinal artery is blocked?

The region affected includes the descending corticospinal tract, ascending spinothalamic tract, and autonomic fibers. It is characterized by a corresponding loss of motor function, loss of pain and temperature sensation, and hypotension. Anterior spinal artery syndrome is the most common form of spinal cord infarction.

What level is the artery of Adamkiewicz?

What level is artery of Adamkiewicz?

Where do segmental medullary arteries come from?

The anterior and posterior segmental medullary arteries are derived from the spinal branches of the ascending cervical, deep cervical, posterior intercostal, and lumbar arteries.

What is the other name of the artery of Adamkiewicz?

The artery of Adamkiewicz, also known as the great anterior radiculomedullary artery or arteria radicularis anterior magna, is the name given to the dominant thoracolumbar segmental artery that supplies the spinal cord. Article:

What is medial medullary syndrome?

Medial medullary syndrome, also known as Déjerine syndrome, is secondary to thrombotic or embolic occlusion of small perforating branches from vertebral or proximal basilar artery supplying the medial aspect of medulla oblongata1,2.

When is collateral circulation possible in Adamkiewicz arterial thrombosis?

Of note, collateral circulation is possible if the artery of Adamkiewicz has progressive occlusion; collaterals usually arise from the muscular branch or other intercostal or lumbar arteries. [3][5] Structure and Function

What is the pathway of the Adamkiewicz arthroscopy?

The artery of Adamkiewicz then passes through the intervertebral foramen and enters the spinal canal adjacent to the exiting spinal nerve (usually ventral or slightly rostrolateral to the dorsal root ganglion/ventral ramus.
