Identification of these vessels failed in five patients (11%), was. considered complete in 31 patients (69%) and incomplete in nine (20%). Selective arteriography classified these patients Into four groups: groups A and B—the artery of Adamkiewicz arose respectively above and below the zoneof operation; group C—the artery arose directly from the segment to be operated; and group Dorigin could not be determined. All 30 patients in group C underwent a spinal cord revascularization procedure (complete in 20 cases, incomplete in 10). Spinal cord complications occurred in 9/45 patients (20%). No spinal cord complications occurred in groups A and B; their incidence was 5%in group C when revascularization was complete, and 50% when revascularization was incomplete; and 60% had complications in group D (p < 0.01). Spinal cord complications were more frequent (p < 0.05) when the artery of Adamkiewicz arose from an intercostal or lumbar artery obliterated at its aortic origin but filled through collaterals or when spinal cord circulation was interrupted for more than 45 minutes. This study confirms the importance of preserving arterial supply to the spinal cord during repair of descending thoracic and thoracoabdominal aneurysms. The information obtained from spinal cord arteriography allows the prediction of complications and informs the choice of the appropriate surgical technique.","claims":[{"public_id":"cl_6f17de3f103548647ac97f11dbebf6bc","status":"active","text":"Selective preoperative arteriography identified the artery of Adamkiewicz and thoracic radicular
