Direct percutaneous embolization of carotid body tumors with NBCA

Abstract

As a carotid body tumor (paraganglioma) is a very hypervascular tumor, preoperative embolization of the feeding arteries is indicated when surgical removal is attempted. We performed percutaneous direct injection of liquid material NBCA into the carotid body tumor preoperatively and blood loss was markedly decreased.
We think this procedure will be popular to embolize hypervascular tumors of the head and neck.
