A case of maxillary cancer treated by intra-arterial therapy using a steerable microcatheter

Abstract

We report on a 69-year-old man with locally-advanced left maxillary sinus cancer who underwent treatment with intra-arterial chemoradiotherapy. Angiography showed that the main feeding arteries were the left maxillary artery and the ophthalmic artery, arising from the internal carotid artery. Due to acute branching of the ophthalmic artery, conventional microcatheters could not be inserted. Using a steerable microcatheter, we were able to repeatedly administer chemoradiotherapy via the ophthalmic artery. The tumor has mostly disappeared after intra-arterial chemoradiotherapy, and the patient is still alive two years after treatment. A steerable microcatheter is very useful for acute-angled vascular branches.
