Impact of Delayed Recovery of Independent Ambulation and Sarcopenia Progression on Long-Term Outcomes Following Endovascular Aortic Aneurysm Repair.

ABSTRACT:

Aim

To evaluate the long-term prognostic impact of delayed recovery of independent ambulation and post-operative sarcopenia progression in patients undergoing endovascular aortic aneurysm repair (EVAR).

Methods

In this multicenter retrospective cohort study, 228 patients (mean age 78.1 ± 6.5 years; 82.5% male) who underwent EVAR for abdominal aortic aneurysm between January 2015 and December 2020 were included. Independent ambulation was defined as walking ≥ 15 m. Sarcopenia was assessed using the psoas muscle index (PMI) at L3 on CT, normalized by height squared. Baseline PMI was measured within 3 months preoperatively; post-operative sarcopenia progression was calculated as ΔPMI/baseline (% change from baseline to 6 months). The primary outcome was all-cause mortality, ana
