Common embolic agents used in interventional radiology

Interventional radiologists use embolic agents to intentionally block blood flow in targeted vessels. These tools are used in procedures for tumors, bleeding, fibroids, enlarged prostate treatment, joint embolization and other conditions.

Common embolic materials include coils, which are small platinum devices that help slow blood flow and form a clot inside a vessel. Particles or beads, often made from polyvinyl alcohol, are widely used for embolization procedures involving fibroids, prostates, tumors, and trauma-related bleeding.

Other agents include medical glue, which hardens inside a vessel and may be useful when less contrast dye is preferred. Lipiodol, an oil-based contrast agent, can help doctors see and guide treatment, especially in tumor procedures or when mixed with glue.

Temporary embolic options are also important. An antibiotic used in embolization can form temporary crystals for joint embolization. Gelfoam, one of the oldest embolic agents, temporarily blocks vessels and can help protect non-target areas during treatment.

Together, these embolic agents give interventional radiologists flexible ways to treat specific vessels while helping improve safety and precision.
