Survival after endovascular therapy in patients with ruptured thoracic aortic diseases: Results from the Global Registry for Endovascular Aortic Treatment Registry.

The Global Registry for Endovascular Aortic Treatment is a prospective observational multicenter cohort registry of all Gore aortic endografts for a variety of aortic pathologies. The purpose of this study was to evaluate the outcome of the Conformable GORE TAG Thoracic Endoprosthesis and GORE TAG Thoracic Endoprosthesis devices for ruptured thoracic aortic syndromes. Between December 2010 and October 2016, a total of 5018 patients were enrolled from 114 international sites in this registry. The database was queried for patients with at least one of the following pathologies: descending thoracic aortic aneurysm with rupture, thoracoabdominal aortic aneurysm rupture, descending aortic dissection rupture, and aortic arch aneurysm rupture. Patient demographics, operative details, and clinical outcomes were analyzed. A total of 40 patients were treated with a ruptured thoracic aortic disease (62.5% male; mean age, 67.5 ± 14.1 years). Nineteen patients were treated for descending thoracic aneurysm rupture, 9 for thoracoabdominal aneurysm rupture, 7 for descending aortic dissection rupture, and 5 for aortic arch aneurysm rupture. Technical success was achieved in 40 of 40 patients (100%). There were no intraoperative mortalities and no conversions to an open procedure. A total of 12 patients (30.0%) required intervention for involvement of at least one aortic branch vessel (4 covered, 5 surgically debranched, 1 stented, and 6 chimney technique). The 30-day mortality was four patients (10.0%). Early reintervention (≤30 days) was required in seven patients (17.5%), five of which were device related. There was a total of five endoleaks and all five required a reintervention. The median follow-up duration was 14.7 months (range, 1-57 months). Freedom from device-related intervention at 1 year was 87.1% (95% confidence interval, [CI], 0.716-0.944), at 2 years was 81.3% (95% CI 0.607-0.917) and at 3 years was 73.1% (95% CI, 0.47-0.878). Freedom from all-cause mortality at 1 year was 65.0% (95% CI, 0.474-0.780), at 2 years was 61.2% (95% CI, 0.431-0.751), and at 3 years was 56.1% (95% CI, 0.369-0.715). The Conformable GORE TAG Thoracic Endoprosthesis and GORE TAG Thoracic Endoprosthesis thoracic endografts provide an effective treatment for ruptured thoracic aortic diseases. Adjunctive coverage or revascularization of an aortic branch vessel may be necessary. Longer follow-up and larger studies are needed to determine durability of these repairs.
