Résumé
Several studies have reported lower mortality and morbidity after thoracic endovascular aortic repair (TEVAR) when compared to open surgical repair (OSR) in the treatment of type B aortic dissection (TbAD). However, there are few studies in the literature on the cost of both treatment options. Thus, the aim of this study is to focus on in-hospital outcomes and cost associated with TbAD repair procedures in a national database in the United States. A retrospective review of the Premier Healthcare Database (PHD) between June 2009 and March 2015 was performed. ICD-9-CM codes were used to identify patients who underwent OSR or TEVAR for TbAD. Endpoints included in-hospital adverse events, in-hospital mortality and hospitalization cost. Logistic regression models and generalized linear models were used to assess the impact of treatment type on the main outcomes. Out of 1752 patients with TbAD, 54.3% underwent OSR and 45.7% underwent TEVAR. Patients in the TEVAR group were older [median age, 64 (IQR 54-73) vs. 59 (IQR 49-70), P < 1] and more likely to have preexisting comorbidities. IAE rates were 78.6% for the OSR group compared to 43.1% for the TEVAR group, P < 0.001. Patients in the OSR group showed significantly higher in-hospital mortality (15.3% vs. 5.9%, P < 0.001). After adjusting for potential confounders, OSR was associated with a 5-fold increase in IAE [aOR(95%CI): 4.8 (3.8-6.1), P < 0.001] and a 3-fold increase in in-hospital mortality [aOR(95%CI): 3.3 (2.1-5.1), P < 0.001]. In regards to charges related to the hospital stay, total cost was significantly higher among patients undergoing OSR $53,371 ($39,029-$80,471) vs. TEVAR $45,311 ($31,479-$67,960), P < 0.001. The present study shows that TEVAR presents an advantage in terms of morbidity, mortality and cost when compared to OSR in the treatment of TbAD. However, long-term cost-effectiveness of both procedures remains unknown. Further research is warranted to see whether the superiority of TEVAR is maintained over time.

BACKGROUND
Several studies have reported lower mortality and morbidity after thoracic endovascular aortic repair (TEVAR) when compared to open surgical repair (OSR) in the treatment of type B aortic dissection (TbAD). However, there are few studies in the literature on the cost of both treatment options. Thus, the aim of this study is to focus on in-hospital outcomes and cost associated with TbAD repair procedures in a national database in the United States.

METHODS
A retrospective review of the Premier Healthcare Database (PHD) between June 2009 and March 2015 was performed. ICD-9-CM codes were used to identify patients who underwent OSR or TEVAR for TbAD.

Patients in the TEVAR group were older [median age, 64 (IQR 54-73) vs. 59 (IQR 49-70), P < 1] and more likely to have preexisting comorbidities. IAE rates were 78.6% for the OSR group compared to 43.1% for the TEVAR group, P < 0.001. Patients in the OSR group showed significantly higher in-hospital mortality (15.3% vs. 5.9%, P < 0.001).

CONCLUSIONS
The present study shows that TEVAR presents an advantage in terms of morbidity, mortality and cost when compared to OSR in the treatment of TbAD. However, long-term cost-effectiveness of both procedures remains unknown. Further research is warranted to see whether the superiority of TEVAR is maintained over time.
