Which of the following embolic agents is classified as a TEMPORARY occluding agent?
- A N-butyl cyanoacrylate (NBCA) glue
- B Gelatin sponge (Gelfoam) ✓
- C Platinum coils
- D Polyvinyl alcohol particles
Correct answer: B. Gelatin sponge (Gelfoam)
Explanation
Gelatin sponge produces vessel occlusion that recanalizes within weeks to months because the material is resorbed, making it suitable for temporary hemostasis such as postpartum hemorrhage or trauma where future reperfusion may be desirable. Coils, cyanoacrylate glue, and polyvinyl alcohol particles all produce permanent occlusion and are chosen when durable vessel closure is required.
