Temporary balloon occlusion and ethanol injection for preoperative embolization of carotid-body tumor

Ear Nose Throat J. 2002 Aug;81(8):536-8, 540, 542 passim.


We report on the preoperative embolization of a carotid-body paraganglioma by temporary balloon occlusion and ethanol injection. Complete devascularization was achieved without complication. Resection after a short postembolization interval required artery sacrifice. Histologic evaluation revealed that the tumor contained diffuse ethanol-induced microemboli. Compared with unembolized and polyvinyl-alcohol-embolized carotid-body paragangliomas, our technique resulted in no greater adverse effects on the tumor-vessel interface. This procedure is an effective and promising method of preoperative embolization of carotid-body tumors and warrants further experience and study. In this article, we also review the literature on carotid-body tumor embolization and ethanol embolization.
