Systematic Evaluation of Collateral Pathways to the Artery of Adamkiewicz Using Computed Tomography

Yoshioka and colleagues evaluated the artery of Adamkiewicz using multidetector row computed tomography in 64 patients. These patients had descending thoracic or thoracoabdominal aortic aneurysms that were associated with the occlusion of the segmental artery from which the artery of Adamkiewicz originated. Seventy-five collateral pathways were identified in 53 patients, and these were more frequently located around the spinal column than in the thoracic wall.
