Based on the identification of the AKA on preoperative MDCT, only 1 critical segmental artery was reattached to the AKA (CSA-AKA). Postoperative MDCT was used to evaluate the patency of the reattached CSA-AKA.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Pre- and postoperative MDCT helped identify and visualize the AKA in all patients (100%). In 8 patients, alternative continuity to the AKA developed through collateral circulation. The total number of CSA-AKA with collateral circulation was 48 among the 32 cases; the number of reattached segmental arteries per case was 1.3 \u00b1 0.9 (range, 0\u20134). The overall rate of patency of the reattached CSA-AKA was 53% (23\/43). Three patients exhibited spinal cord injuries (paraplegia, 2; paraparesis, 1). In the 2 paraplegia cases exhibiting partial or complete occlusion of the reattached CSA-AKA, the development of collateral circulation was not visualized via postoperative MDCT. In the paraparesis case, postoperative MDCT helped visualize the development of collateral circulation to the CSA-AKA, resulting in full recovery at discharge.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>The study findings suggest that spinal cord injuries do not occur in the presence of a patent preoperatively identified CSA-AKA or the development of collateral circulation. Pre- and postoperative identification of collateral pathways to the AKA may help reveal paraplegia risk factors.<\/jats:p>\n
