[Chemoembolization of maxillary carcinoma via the superficial temporal artery using a coaxial catheter system]

To perform chemoembolization of maxillary carcinoma, an approach through the superficial temporal artery was applied. A 5-French guiding catheter was advanced into the maxillary artery. The microcatheter was advanced into the terminal portion of the maxillary artery through the guiding catheter, and then carboplatine microcapsules were infused into the feeding artery. Chemoembolization was performed twice in one patient and three times in another. This new method will make it feasible to repeat chemoembolization in patients with head and neck tumors.
