Technical report demonstrates procedural techniques for shape memory polymer plugs in venous embolization, indicating effective vessel occlusion with minimal imaging artifacts.
Purpose: Shape memory polymer plugs are novel, porous, self-expanding embolic devices that promote homogeneous thrombus formation with minimal imaging artifacts. Although increasingly used in arterial procedures, clinical data on venous applications remain limited. This technical note describes our initial experience with shape memory polymer plugs for multiple types of venous embolization and details the procedural techniques used to optimize outcomes.
