Embolization — Principles, Embolic Agents & Applications

📊 Key Facts at a Glance

• Calibrated microspheres from 100 to 900 µm
• Multiple embolic agent types: coils, particles, glue

📖 Embolization — overview

Embolization is one of the most versatile techniques in interventional radiology. A catheter inserted through the skin (usually at the groin) is guided to the target blood vessel under X-ray. Embolic agents are then injected to deliberately block it — stopping blood supply to a tumour, controlling haemorrhage, or treating vascular abnormalities.

Key advantages: no incision, local anaesthesia, same-day discharge in most cases. Embolization has replaced or supplemented surgery in many clinical scenarios, with equivalent efficacy and significantly lower morbidity.
