Gallbladder necrosis after transcatheter hepatic arterial embolization: a technique to avoid this complication.

We present a technique used to avoid unnecessary embolization of the cystic artery in the treatment of hepatoma by transcatheter arterial embolization. A special long tapering catheter that is flexible and soft enough to be inserted into the distal small branches of the heptic artery is used. Embolic material ( Oxycel , absorbable cellulose) was mixed with Mitocin -C (mitomycin) and contrast material. This mixture will help to avoid reflux.
