Abstract 19488: Improved Success in Patency and Symptomatic Relief Using Optical Coherence Tomography Guided Superficial Femoral Artery Chronic Total Occlusion Intervention Compared With Standard Techniques

Abstract

Background: Superficial femoral artery (SFA) chronic total occlusion (CTO) peripheral vascular intervention (PVI) is a challenging procedure given the longer procedure times, larger amount of radiation dose, and lesser procedural success. The aim of this single center analysis is to determine if patency and symptom relief is improved using Optical Coherence Tomography (OCT) based Ocelot versus conventional guidewires in SFA CTO PVI. Methods: We retrospectively analyzed 213 patients with SFA CTO undergoing PVI with either traditional techniques or the Ocelot device. Outcomes measured were death, vascular complications, procedural success, Rutherford class improvement, and a composite endpoint of ABI improvement above 0.9, ultrasound duplex velocity less than 250 m/s and Rutherford improvement. Unadjusted and multivariate analyses were performed. Results: 36 cases of SFA CTO were performed with the Ocelot device, while 177 were performed with traditional guidewire techniques. Both improvement in Rutherford Class and the composite endpoint of success were significantly better with using the Ocelot device in the unadjusted analysis. They remained significant after performing multivariate analysis. Conclusion: The Ocelot device is a revolutionary device the successful and effective management of SFA CTO PVI. Symptomatic relief and patency are demonstrated here to be significantly improved when utilizing the Ocelot device. Further analysis of lesion length and calcium burden are needed to determine its optimal use for procedural and long term success.
