The EVUS CTO score serves as a useful tool for stratifying lesion complexity, predicting early procedural success, and aiding in case selection, operator training, and procedural planning for FP-CTO interventions.Clinical ImpactThis study identifies key predictors of successful extra-vascular ultrasound (EVUS)-guided wiring within 30 minutes in femoropopliteal chronic total occlusions and introduces a simple EVUS CTO score. This scoring system allows clinicians to stratify lesion complexity and predict early technical success, thereby improving case selection and procedural planning. By anticipating procedural difficulty, EVUS-guided intervention can be performed more efficiently, potentially reducing procedure time and radiation exposure. These findings support a more structured and practical approach to EVUS-guided peripheral intervention.
