Thoraco-abdominal aortic replacement can be associated with a high incidence of paraplegia. Because the major source of blood supply to the thoraco-abdominal spinal cord is through the anterior spinal artery of Adamkiewicz, reimplantation of intercostal and lumbar arteries could reduce the risk of this operation. We used intraarterial digital subtraction angiography (DSA) for preoperative localization of the anterior spinal artery in 12 patients. This vessel was successfully located in 9 patients, with DSA providing good quality images in all patients. Preoperative knowledge of the origin of this vessel was helpful in the planning of the operation in all patients, but its efficacy as a routine procedure was not established.
胸腹主动脉置换术可能伴有较高的截瘫发生率。由于胸腹段脊髓的主要血供来源是Adamkiewicz前脊髓动脉，肋间动脉和腰动脉的再植入可降低该手术的风险。我们对12例患者采用动脉内数字减影血管造影（DSA）术进行Adamkiewicz前脊髓动脉的术前定位。该血管在9例患者中成功定位，所有患者的DSA均提供了高质量图像。该血管起源的术前信息对所有患者的手术规划均有帮助，但作为常规操作其有效性尚未确立。
