Background The long-term complication rates of open repair and thoracic endovascular aortic repair (TEVAR) have not yet been determined. Therefore, this study aimed to compare the long-term outcomes and aortic reintervention rates between open repair and TEVAR in patients with descending thoracic aortic pathologies.
Methods Between January 2002 and December 2017, 230 patients with descending thoracic aortic pathologies underwent surgery. Of these, 136 patients were included in this retrospective study: 45 patients (10, 2, and 33 with dissection, penetrating atherosclerotic ulcer, and pseudoaneurysm, respectively) underwent open repair and 91 patients (27, 1, and 63 with dissection, penetrating atherosclerotic ulcer, and pseudoaneurysm, respectively) underwent TEVAR. The primary end points were in-hospital mortality, and short-term complications. The secondary end points were long-term mortality and reintervention rates. Based on the propensity score matching (PSM), 35 patients who underwent open repair were matched to 35 patients who underwent TEVAR (ratio= 1:1).
Results The mean follow-up period was 70.2 ± 51.9 months. Shorter intensive care unit and hospital stay were seen in the TEVAR group than in the open repair group before and after PSM (p < 0.001 and p < 0.001, respectively). However, in-hospital mortality, and spinal cord ischemia were not significantly different among the two groups (before PSM: p = 0.068 and p = 0.211, respectively; after PSM: p = 0.303 and p = 0.314, respectively). The cumulative all-cause death and aorta-related death showed no significant differences between the two groups (before PSM: p = 0.709 and p = 0.734; after PSM: p = 0.888 and p = 0.731, respectively). However, aortic reintervention rates were higher in the TEVAR group than in the open repair group before and after PSM (p = 0.006 and p = 0.013, respectively).
Conclusion The TEVAR group was superior in short-term recovery outcomes but had higher reintervention rates compared to the open repair group. However, there were no significant differences in long-term survival between the two groups.
