Fig 1 Preoperative assessment of the Adamkiewicz artery (AKA) and its collateral arteries. (A) Magnetic resonance angiography demonstrates the AKA (arrows) that originates from the posterior branch of the left eighth intercostal artery (arrow heads) and anastomoses with the anterior spinal artery (chevrons). (B). Arrows and red lines indicate the collateral sources of the AKA. These arteries were considered at risk using the standard Stoney’s incision.
