How we do it: artery of Adamkiewicz evaluation by CTA in children
Abstract
Identifying the artery of Adamkiewicz (AoA) is essential for minimizing the risk of spinal cord ischemia that can result from injury or displacement during aortopexy. A pre-operative CT angiogram (CTA) is commonly requested; however, locating the artery can be challenging due to its small size and variable course. To enhance the visualization of the artery of Adamkiewicz, it is effective to increase the tube current while maintaining a low kV of 70 and raising the Hounsfield unit (HU) trigger threshold. This method adheres to the As Low As Reasonably Achievable (ALARA) principle, ensuring a reliably diagnostic study.
