BACKGROUND: The risk factors of paraplegia and paraparesis (P/P) after surgical repair of descending thoracic aortic aneurysm (TAA) are controversial. PATIENTS AND METHODS: Seventy five patients underwent surgical repair of descending TAA from 2001 through 2002. The mean age was 64.2+/-5.2 years old (range; 26-81) and 58 patients (77.3%) are male. There were 47 patients (62.7%) with nondissecting aortic aneurysm and 28 patients (37.3%) with chronic dissecting aortic aneurysm. Emergent operation was performed in 13 cases (17.3%). Retrospective analysis based on data of these 75 patients was performed to determine the risk factors of P/P. RESULTS: 30-days hospital mortality was 2.7%. The overall incidence of P/P was 12.0% (9/75) overall (immediate paraplegia; 4 (5.3%), delayed paraplegia; 1 (1.3%), immediate paraparesis; 3 (4.0%), delayed paraparesis; 1 (1.3%)). Logistic regression analysis revealed that predictive factors of the development of P/P were; cases in which the distal part (below Th9) of the descending thoracic aorta was included in the extent of graft replacement (P=0.020; odds ratio (OR), 7.981) and nondissecting aneurysm (P=0.029; OR, 12.109). CONCLUSION: There was an increased risk of P/P after descending TAA repair in cases in which the extent of graft replacement included below the Th9 or in cases with nondissecting aortic aneurysm.
