What is it about?

Tract embolization using gel-like radiopaque embolic material with two sheets of gelatin sponge and 3 mL of contrast agent offers a safe, feasible, and economical procedure after trans-organ puncture, because the material offers the following characteristics: visibility under X-ray; viscosity facilitating retention in the tract; ability to allow repeated puncture via the same route; and low cost.

Why is it important?

Gel-like radiopaque embolic material is visible under X-ray fluoroscopy to allow confirmation of tract embolization. Gel-like radiopaque embolic material has high viscosity in itself and is capable of stagnation on the tract to avoid bleeding from the tract as a major complication during tract embolization. contrast enhancement of gel-like radiopaque embolic material definitively disappeared from the tract on follow-up CT. So tract puncture allows repeated procedures via the same route. The costs of gel-like radiopaque embolic material per procedure in Japan were $4 for gel-like materials.


We hope this method will spread around the world.
