Association between False Lumen Origin of Segmental Arteries and Postoperative Spinal Cord Injury in Acute Type A Aortic Dissection

Year: 2026

Type: article

Abstract: PURPOSE: We examined whether false lumen-origin segmental arteries (SAs) were associated with postoperative spinal cord injury (SCI) after surgery for acute Stanford type A aortic dissection (ATAAD). METHODS: We reviewed 201 consecutive patients who underwent open repair for ATAAD between January 2008 and February 2026. After prespecified exclusions, 124 patients were analyzed, including 83 with evaluable contrast-enhanced computed tomography for detailed SA assessment. RESULTS: Postoperative SCI occurred in 9 patients (7.3%), who comprised the SCI group; the remaining 115 comprised the non-SCI group. Total arch replacement and frozen elephant trunk use were numerically more frequent in the SCI group. In the detailed cohort, the number of false lumen-origin SAs was higher in the SCI group at T3-T7 (7.2 ± 3.0 vs. 3.9 ± 3.1, P = 0.042) and T8-L2 (10.3 ± 2.7 vs. 5.5 ± 4.2, P = 0.005). The corresponding proportions were also higher at T3-T7 (77.5% vs. 45.2%, P = 0.047) and T8-L2 (75.0% vs. 41.9%, P = 0.010). CONCLUSION: In this exploratory single-center cohort, false lumen-origin SAs were associated with postoperative SCI in unadjusted analyses. Further studies are needed to determine their value for preoperative risk stratification.
