AVF Day 3: International Session on Venous Disease Innovations
Cardiac Function and Iliofemoral Stenting
A UK team used exercise cardiac MRI to show iliofemoral outflow obstruction impaired peak oxygen uptake and stroke volume before stenting, with marked gains in exercise capacity and quality of life after stenting.
Reflux Patterns and CEAP Classification
A large retrospective review found saphenofemoral reflux equally common in mild and advanced disease, while below knee segmental reflux extent tracked with more advanced skin changes. Discussion clarified CEAP class describes disease category, not severity.
Ablation Technology and Technique
Presenters shared early experience with high intensity focused ultrasound ablation, improving efficacy after technique refinement, and outcomes showing ablation benefits patients with mild reflux. A Japanese group characterized cyanoacrylate hypersensitivity reactions and found steroid and antihistamine premedication reduced their frequency.
Recanalization and Inflow Reconstruction
A VQI registry analysis linked truncal vein recanalization to body mass index, phlebitis, and veins treated per procedure. A Norwegian group described a hybrid endophlebectomy and single stent technique for post thrombotic obstruction with compromised inflow, achieving durable two year patency in an initial series.
