To perform vascular occlusion via IO methods, a thorough understanding of the occlusive agents is mandatory. Two broad categories, based on the positioning of the agents in the vessels exist: those delivered into the vessel and carried passively to a target vessel (particles and liquids) and those that are positioned at the site where occlusion is needed (coils and balloons) (Kunstlinger et al. 1981; Ginat et al. 2009; Loffroy et al. 2009). The agent chosen depends on the goal of the procedure, and multiple agents may be indicated and used in the same patient.
