Abstract

Background: This study aimed to analyze the influence of the timing of intervention from presentation of symptoms to thoracic endovascular aortic repair (TEVAR) and its relation to major complications. Data were collected from the Japan Adult Cardiovascular Surgery Database. Methods: We retrospectively analyzed the data of 680 patients who underwent TEVAR for acute and subacute type B dissection between January 2008 and January 2013. Results: Thoracic endovascular aortic repair for type B dissection was performed in 680 patients: 295 repairs were performed within 24 hours of presentation of symptoms (hyperacute); 97 between 24 hours and 14 days (acute); and 288 between 14 days and 6 weeks (subacute). Hyperacute patients more frequently had immediate life-threatening complications from type B dissection such as rupture or malperfusion than did acute or subacute patients (41.0% [121 of 295] versus 7.2% [7 of 97] versus 4.2% [12 of 288]; p < 0.001; and 17.3% [51 of 295] versus 8.3% [8 of 97] versus 5.6% [16 of 288]; p < 0.001, respectively). Operative mortality and severe complications including aortic dissection were more common among hyperacute patients (11.9% [35 of 295] versus 0% [0 of 97] versus 1.7% [5 of 288]; p < 0.001; and 32.5% [96 of 295] versus 10.3% [10 of 97] versus 8.3% [24 of 288]; p < 0.001, respectively) and did not differ significantly between acute and subacute patients (p = 0.191 and p = 0.553, respectively). Conclusions: Although TEVAR performed for aortic dissection within 24 hours of presentation of symptoms was associated with worse outcomes, TEVAR performed between 24 hours and 14 days, as compared with TEVAR between 14 days and 6 weeks, does not appear to increase the risk of perioperative complications.
