“Beyond saving lives”: Current perspectives of interventional radiology in trauma

Table 2 Embolizing agents precluded in traumatic injuries[6-10]

Embolizing agent	Reason
Powdered form gelatin sponge	Obliteration of small caliber vessels: May lead to infarction or abscess Large caliber vessels: Risk of rebleeding due to potential collateralization from neighboring undamaged parenchyma
Non absorbable particles of small size (e.g., polyvinyl alcohol), liquid embolic agents (glue)	Difficult to handle: Striking balance between selective embolization vs optimizing end point of embolization an issue Non-targeted embolization: Irreversible unwanted tissue damage
Alcohol	Extensive tissue necrosis Difficult to the handle while delivering at the target site
