Abstract:
The Adamkiewicz artery(AKA)is the major blood supply of the spinal cord in the thoracolumbar region.The anterior two thirds of the spinal cord receive blood supply from the AKA and 75% blood supply of the spinal cord comes from the AKA.The AKA diameter is reported to be only 0.8 ～ 1.3 mm in the thoracolumbar region.In order to prevent ischemic injury to the spinal cord,the anatomy of the blood supply of the spinal cord needs to be recognized completely before invasive treatment taken in the descending thoracic and proximal abdominal aorta.Although selective angiography has been recommended,but it is time-consuming and hazardous.Multi-detector row helical CT can provide a simple protocol of scanning and relatively brief postprocessing depicting the Adamkiewicz artery with a high successful rate.Optimizing the flow velocity of contrast medium and the using of scan-triggering CT threshold are the keys of success.
