Embolization deliberately occludes a target vessel to control bleeding, devascularize a tumor, or treat a vascular malformation. Agent selection — coils, plugs, particles, or liquid embolics — is matched to the vascular territory, the goal of treatment, and the desired level and permanence of occlusion.
Clinical context
This article examines embolic agents in interventional radiology classification selection criteria and clinical applications within the wider field of embolization. Superselective microcatheter delivery concentrates the embolic effect on the target while sparing adjacent normal tissue. Liquid embolic agents penetrate a malformation nidus or tumor bed and are suited to lesions that cannot be reached by discrete devices alone.
Key considerations
- Superselective microcatheter delivery concentrates the embolic effect on the target while sparing adjacent normal tissue.
- Liquid embolic agents penetrate a malformation nidus or tumor bed and are suited to lesions that cannot be reached by discrete devices alone.
- Detachable coils allow controlled, retrievable positioning before final release, improving precision in aneurysm and vessel occlusion.
- Vascular plugs achieve rapid, single-device occlusion of larger high-flow vessels.
Diagnosis and evaluation
Careful patient selection and imaging-based evaluation underpin good outcomes in this area. Terminology that frequently arises includes nidus, superselective, microcatheter, non-target embolization. A structured assessment helps match the individual patient to the most appropriate treatment pathway.
Treatment approaches and technologies
Detachable coils allow controlled, retrievable positioning before final release, improving precision in aneurysm and vessel occlusion. A range of device technologies supports contemporary practice in embolization.

Summary
Embolic Agents In Interventional Radiology Classification Selection Criteria And Clinical Applications is an important topic in embolization. Sound patient selection, appropriate technique, and well-matched technology together support safe, effective care. INVAMED develops technologies used by clinicians worldwide across this and related fields.
