Vascular supply with angio-CT for superselective intra-arterial chemotherapy in advanced maxillary sinus cancer

Recently popularised, the combined angiography and CT (angio-CT) system is useful for correctly identifying the feeding arteries and their perfusion in various organs. We applied this system for advanced maxillary cancer to expose its feeding arteries and their supplying territories. In addition to the maxillary artery, extramaxillary feeding arteries were usually observed, including the ophthalmic, accessory meningeal, facial, transverse facial and ascending palatine arteries. These extramaxillary feeding arteries exhibited uniform tendencies, depending on the site of extramaxillary tumour extension.
