Intraoperative vascular patency assessment is critical, but what options are available to ensure you close with confidence? This webinar will explore methods available for evaluating patency at the time of arterial revascularisation, such as angiography, Duplex Ultrasound, and intraoperative Doppler probes. Join leading UK and international vascular surgeons as they share their insights and gain an understanding of what practices are adopted, factors to consider in choosing a single or a multi-modality approach, and, how do we enhance success?
Register now, for what promises to be an engaging and interactive session. There will be plenty of opportunity to ask questions and learn from experts in our first webinar series exploring intraoperative vascular patency assessment!
