Predictors of Major Adverse Limb Events After Endovascular Iliac Stenting: a Real-world Cohort Study

Peripheral arterial disease involving the iliac arteries is a common manifestation of systemic atherosclerosis and a major cause of lifestyle-limiting claudication and chronic limb-threatening ischemia. Endovascular iliac artery stenting has become the preferred treatment strategy for most iliac lesions, including complex TransAtlantic Inter-Society Consensus II (TASC II) C and D lesions, owing to high technical success rates and lower perioperative morbidity compared with open surgical reconstruction. Despite widespread adoption of endovascular treatment, available evidence regarding predictors of major adverse limb events (MALE) after iliac artery stenting remains limited, particularly in unselected real-world populations with substantial comorbidity burden. Patient-related factors, including frailty, may contribute to post-procedural outcomes in addition to lesion-related characteristics. This retrospective single-center cohort study will evaluate clinical outcomes following endovascular iliac artery stenting in consecutive adult patients treated at IRCCS Galeazzi-Sant'Ambrogio Hospital, Milan, Italy. The study will assess the occurrence of major adverse limb events (MALE), primary patency, peri-procedural complications, target lesion revascularization, restenosis or occlusion, and all-cause mortality. Clinical, anatomical, and procedural factors associated with adverse limb outcomes, including frailty assessed by the modified five-item Frailty Index (mFI-5), will also b…
