Multicenter Study Comparative Study Controlled Clinical Trial
International controlled clinical trial of thoracic endovascular aneurysm repair with the Zenith TX2 endovascular graft: 1-year results.
This trial evaluated the safety and effectiveness of thoracic endovascular aortic repair (TEVAR) with a contemporary endograft system compared with open surgical repair (open) of descending thoracic aortic aneurysms and large ulcers. ⋯ Thoracic endovascular aortic repair with the TX2 is a safer and effective alternative to open surgical repair for the treatment of anatomically suitable descending thoracic aortic aneurysms and ulcers at 1 year of follow-up. Device performance issues are infrequent, but careful planning and regular follow-up with imaging remain a necessity.

Randomized Controlled Trial Multicenter Study Comparative Study
The Glasgow Aneurysm Score as a tool to predict 30-day and 2-year mortality in the patients from the Dutch Randomized Endovascular Aneurysm Management trial.
Randomized trials have shown that endovascular repair (EVAR) of an abdominal aortic aneurysm (AAA) has a lower perioperative mortality than conventional open repair (OR). However, this initial survival advantage disappears after 1 year. To make EVAR cost-effective, patient selection should be improved. The Glasgow Aneurysm Score (GAS) estimates preoperative risk profiles that predict perioperative outcomes after OR. It was recently shown to predict perioperative and long-term mortality after EVAR as well. Here, we applied the GAS to patients from the Dutch Randomized Endovascular Aneurysm Repair (DREAM) trial and compared the applicability of the GAS between open repair and EVAR. ⋯ This is the first evaluation of the GAS in a randomized trial comparing AAA patients treated with OR and EVAR. The GAS can be used for prediction of 30-day and 2-year mortality in both OR and EVAR, but in patients that are suitable for both procedures, it is a better predictor for EVAR than for OR patients. In this study, the GAS was most valuable in identifying low-risk patients but not very useful for the identification of the small number of high-risk patients.
