In Vivo Feasibility of Arterial Embolization with a New Permanent Agar-agar-Based Agent.

Purpose: Evaluate the safety and efficacy of an eco-friendly permanent agar-agar-based embolization agent (ABEA) (EmboBio®) for intra-arterial use.

Materials And Methods: Six pigs embolized with one ABEA torpedo (6 lower polar renal and 6 lumbar arteries) and one coil (6 lower polar renal and 6 lumbar arteries). Technical success was defined as a complete occlusion with no residual flow in DSA.
