The association of preprocedural C-reactive protein/albumin ratio with in-stent restenosis in patients undergoing iliac artery stenting

Over the last few decades, endovascular techniques for AIOD have increasingly improved, resulting in a significant shift from open surgical procedures toward less-invasive percutaneous interventions, including balloon angioplasty and stenting.2 However, despite significant advances in stent technology, in-stent restenosis (ISR) remains a potential problem, particularly during the long-term follow-up period. [...]in the current literature, there is a shortage of data with respect to the relation of CAR with ISR in patients undergoing iliac artery stenting. [...]our main aim was to investigate the relationship between the preprocedural CAR and ISR development in subjects with aortoiliac disease undergoing a stenting. [...]subjects with incomplete data were not included in this analysis. In the present study, subjects who were on chronic renal replacement therapy and who had a diagnosis of acute coronary syndrome in last six months, chronic heart failure, permanent or paroxysmal atrial fibrillation, overt and/or active systemic organ disease, active or chronic infection, malignancy, endstage diseases were not included. [...]patients who had overlapping stents were not enrolled in order to preclude confounding bias.
