Superficial femoral artery chronic total occlusion crossing strategies

Abstract

Objectives: Superficial femoral artery (SFA) endovascular intervention procedures are one of the most common peripheral artery interventions (PAI) in the lower extremities around the world. Chronic total occlusions (CTO) are extremely common in this vascular bed, accounting for approximately 40–50% of all lesions treated. One of the most crucial decisions an operator must make for a good chronic total occlusion (CTO) recanalization is selecting the right catheter vascular access site. Methods: A prospective, cohort, study conducted on 30 patients to evaluate the safety and efficacy of different strategies for crossing the chronic total occlusion of superficial femoral artery. Results: There was statistically significant difference found between crossing techniques regarding DM and combined DM and dyslipidemia. Conclusion: Correlation of CTOP classification with larger sample size may show importance and improve crossing strategies.
