Abstract
Embolization materials can be classified according to their physical and biological characteristics. They are chosen according to the following:
Characteristics of the target vessels: size, flow, and type of vessel (artery or vein).
Permanent particulate agents are not resorbed and are intended to provide durable occlusion (Fig.3.1).
The level of arterial occlusion obtained with particulate agents varies from proximal to distal according to the chosen agent.
Recanalization can occur due to expulsion, distal migration, fragmentation of the embolization material, and formation of a new vessel lumen.
Occlusion can be purely mechanical or may be a conjunction of different mechanisms with vessel wall destruction by inflammation or sclerosis.
