BACKGROUND: Endovascular repair of aortic diseases is a well-established therapeutic alternative for patients with appropriate anatomy and/or high surgical risk, providing lower morbidity and mortality rates. This study aimed at analyzing the outcomes of asymptomatic patients undergoing endovascular treatment of thoracic aortic dissections with aortic diameter > 5.5 cm or endoleaks. Technical success, therapeutic success, morbidity and mortality and perioperative complication and reintervention rates were assessed. METHODS: Retrospective study, performed at a reference center from January 2010 to July 2011, which analyzed consecutive patients undergoing endovascular repair of chronic complicated type B aortic dissection according to Stanford classification. RESULTS: Twenty-six patients were treated. Mean age was 56.4 ± 7 years and 61.5% were male. Technical and therapeutic success rates were 100% and 74%, respectively. Perioperative mortality was 7.6% and the mortality rate in the first year of follow-up was 19.3%. The reintervention rate was 15.3%. CONCLUSIONS: In our study, the endovascular treatment of chronic type B aortic dissection proved to be a feasible method with acceptable perioperative complication rates. Therapeutic success and reintervention rates demonstrated the need of a close and careful clinical follow-up of these patients.
