Evidence of Collateral Supply to Adamkiewicz Artery after Stentgrafting of the Lower Thoracic Descending Aortic Aneurysm

Abstract

We encountered a case who escaped ischemic spinal cord injury following stentgrafting of the lower thoracic descending aorta, though the Adamkiewicz artery and its feeding intercostal arteries were confirmed preoperatively by a multi-detector row computed tomography (MDCT) and these were completely blocked by the stent graft. Postoperative MDCT demonstrated clear evidence of collateral supply to the Adamkiewicz artery which might have helped this patient avoid serious complications.
