신동맥하부 대동맥의 병소나 수술과 관련된 허혈성 척수 손상

Abstract

Ischemic injury of the spinal cord is rare complication of infrarenal aortic pathology or procedure. So many vascular surgeons are unfamiliar to this complication. But once developed, the impact of this complication is unendurable not only to the patient and his or her family but also to the surgeon. The importance of great anterior medullary artery was well known. Recently, the role of pelvic collateral circulation has been emerged and stressed. In Korea, spinal cord ischemia related to infrarenal aortic pathology or surgical procedure was not reported until recently. Authors had experienced two paraplegic patients, one after elective aortobifemoral bypass due to aortoiliac occlusive lesion in 49 years old male and the other due to acute thrombotic occlusion of infrarenal aorta in 40 years old male. To inform the possibility of ischemic cord injury in infrarenal aortic procedure and pathology, we report our experiences with review of literatures.
