Previous studies have demonstrated that endovascular and open repair are similarly effective. These findings led to a significant increase in the adoption of the less-invasive endovascular-first (EVF) approach. However, it remains unknown whether the 2 treatment modalities have similar durability in today's real-world setting. The aim of the present study was to compare the midterm outcomes of the EVF and bypass-first (BF) strategies in patients with CLTI.

We identified all patients who had undergone limb revascularization from January 2010 to December 2016 in the Vascular Quality Initiative Medicare-linked database. Patients with a history of previous revascularization and those who had undergone hybrid or …
