Retrospective analysis reveals predictors of sac shrinkage in patients with aortic arch aneurysms after surgery, highlighting the importance of aneurysm shape.
Key Points
Twelve out of 28 patients experienced sac shrinkage after total arch replacement, indicating significant effectiveness of the intervention.
Cumulative sac shrinkage rates at 1, 2, and 3 years were observed at 42%, 47%, and 47%, suggesting stability over time.
Multivariable analysis identified shorter preoperative sac length and a higher sphericity index as key predictors of sac shrinkage.
Study findings support the association between aneurysm geometry and postoperative outcomes, emphasizing tailored surgical approaches.
