Another blood supply to Adamkiewicz's artery.
A 76-year-old man underwent endovascular stent-grafting therapy for chronic aortic dissection. The preoperative multi detector row helical computed tomography (CT) revealed that Adamkiewicz's artery originated from the level of thoracic 9 intercostal artery. Intraoperative monitoring of motor evoked potentials showed no reduction of amplitude in the anterior tibialis muscle after deployment retrievable stent-graft. Postoperative CT showed that stent-graft blocked the ostium of intercostal arteries including Adamkiewicz's artery. On the other hand, the distal portion of the Adamkiewicz's artery was clearly enhanced. Our result showed that there is a collateral network supplying to Adamkiewicz's artery.
