The aim embolization is to devascularize the tumor bed by filling intratumoral vascularization as deep as possible into the precapillary level to initiate tumor necrosis, decrease blood loss during surgery and thus make it easier and possibly, more radical, and in tumor of nasal cavity to stop epistaxis. The procedure is angiographically guided.
Embolization of a tumor is performed by either an intraarterial catheterization approach or direct puncutre of the tumor artery. Selection of one of these approaches depends of the location, and number of arterial feeders of the tumor. result of devascularization is verified by contrast enhanced CT or MR imaging.
