Summary

This study looked at how well surgery works for people with an enlarged aorta (aneurysm) in the chest. Researchers compared outcomes in 50 patients who had surgery versus those who did not, tracking deaths and how fast the aorta grew over time. The goal was to better understand when surgery is most helpful.
