Computed tomography angiography using 64-row multi-slice CT clearly demonstrated the artery of Adamkiewicz and its collateral circulation via the left thoracodorsal artery.
Case Report (n=1)
Multi-slice CT angiography can effectively visualize complex collateral circulation to the artery of Adamkiewicz in patients with thoraco-abdominal aortic aneurysms.

CT angiography may delineate Adamkiewicz collaterals before TAAA EVAR; leaves open whether routine use reduces paraplegia risk.
A 59-year-old woman with a thoraco-abdominal aortic aneurysm was hospitalised and scheduled to undergo endovascular aneurysm repair. Computed tomography (CT) angiography using 64-row multi-slice CT clearly demonstrated the artery of Adamkiewicz and its collateral circulation via the left thoracodorsal artery (Figs. 1 and 2 ). The posterior view of volume-rendering image with semitransparent skeletal system shows that the left 8th intercostal artery (ICA 8), which is the origin of the artery of Adamkiewicz (arrow), is occluded proximally at the aorta. This image also shows collateral circulation from the left thoracodorsal artery (TDA) to ICA 8. T8: 8th thoracic vertebra. A curved planar reformatted image shows full continuity from the TDA to the artery of Adamkiewicz artery (arrow) via ICA 8.

Yoshioka et al. (2009) conducted a case report in Thoraco-abdominal aortic aneurysm (n=1). 64-row multi-slice CT angiography was evaluated on Demonstration of the artery of Adamkiewicz and its collateral circulation. Computed tomography angiography using 64-row multi-slice CT clearly demonstrated the artery of Adamkiewicz and its collateral circulation via the left thoracodorsal artery.
