Absorbable gelatin compressed sponge (Gelfoam) embolization of distal external carotid artery branches in intra-arterial chemotherapy for retinoblastoma.

Intra-arterial chemotherapy in retinoblastoma using Gelfoam to transiently occlude the distal branches of the external carotid artery and reverse the backflow into the ophthalmic artery seems feasible and safe. Larges series will help to confirm the effectiveness of this new technique.
