Abstract:
Percutaneous vascular embolization is one of the major applications of interventional radiology. A wide variety of embolization agents are currently available for clinical use. The interventional radiologist needs to be up to date with the newer and different types of embolic agents available along with their biopharmaceutical characteristics, strengths, and weaknesses that have been reviewed. For the purpose of this review, we have classified embolization agents into mechanical occlusion devices, particulate agents, and liquid agents, with some degree of overlap between some of the agents.
