Adamkiewicz artery demonstrated by MRA for operated posterior mediastinal tumors.
In the thoracolumbar region, it is well known that the great anterior medullary artery (the artery of Adamkiewicz: AKA) is the dominant feeder of the spinal cord. During surgery for posterior mediastinal tumor adjacent to the lower thoracic aorta, perioperative distortion of the spinal cord blood supply could lead to neurological complication. To avoid postoperative paralysis, it would be useful to know the level of the intercostal artery from which the AKA originates. Recently, we have attempted to identify the AKA preoperatively using magnetic resonance angiography (MRA).
