Combined distal embolization protection and rheolytic thrombectomy to facilitate percutaneous revascularization of totally occluded saphenous vein grafts

Totally occluded saphenous vein grafts are difficult to treat percutaneously with a higher likelihood of distal embolization and slow-flow or no-reflow during percutaneous interventions. The PercuSurge system, which utilizes a distal balloon occlusive device, has been shown to improve clinical outcomes during saphenous vein graft (SVG) interventions. This device may not be optimal in the setting of heavy thrombus or debris burden, a situation frequently encountered in totally occluded SVGs. Rheolytic thrombectomy facilitates percutaneous interventions by effectively removing intraluminal thrombus and debris but lacks distal embolization protection. We report our experience with the synergistic use of balloon-based distal embolization protection (PercuSurge) and rheolytic thrombectomy (AngioJet) to optimize percutaneous revascularization of totally occluded SVGs.
