From which vertebrae does the artery of Adamkiewicz most commonly arise?

The artery of Adamkiewicz, also known as the great anterior radicular artery, is a significant blood supply to the lower spinal cord. It most commonly originates from the segmental artery between the T8 and L2 vertebrae. This artery plays a crucial role in supplying blood to the anterior portion of the spinal cord, particularly the lumbar and sacral regions. Its location is important in clinical settings, especially in the context of spinal surgeries or interventions that could potentially compromise blood flow to the spinal cord.

The choice indicating the range of T8 to L2 accurately reflects the typical anatomical pattern observed in the majority of individuals. Understanding this specific origin point is essential for medical professionals when considering blood supply implications during procedures involving the thoracic and lumbar spine.
