Background: Open surgical repair (OSR) for TAAs is associated with a high perioperative morbidity and mortality, depending on the extent of repair .Also, as a result of the high mortality rates associated with OSR; stable patients with uncomplicated type B AD frequently obtain medical treatment.
Objectives To evaluate the efficacy and predictors of outcomes of early thoracic endovascular aortic repair in patients with uncomplicated type B aortic dissection and patients with thoracic aortic aneurysms.
Methods: A total of 25 patients with uncomplicated type B AD and descending thoracic aortic aneurysm who underwent endovascular aortic repair in National Heart Institute in the period between 2015 and 2017 were included in the study.
Results: Of the 25 patients, 5 patients had a descending thoracic aortic aneurysm, and 20 patients had uncomplicated type B AD,the total mortality rate was 8 % throughout the follow-up. Procedure related complications were observed in 8 % of the study population, where 2 patients developed type I endoleak, which resolved spontaneously later during the follow up period .Both death and endoleak occurred in subacute and chronic cases, while using TEVAR in acute AD and aortic aneurysms showed no complications.
Conclusion: Early thoracic endovascular aortic repair, along with optimal medical therapy, in uncomplicated type B aortic dissections and thoracic aortic aneurysms is associated with better outcome.
