Ligation of the ethmoid arteries in superselective intra‐arterial infusion of cisplatin for advanced maxillary sinus cancer fed by the ophthalmic artery

Abstract

AbstractBackgroundSuperselective cisplatin (CDDP) infusion via the external carotid artery system and concomitant radiotherapy (RADPLAT) provides favorable oncological and functional outcomes in patients with maxillary sinus cancer. However, targeted lesions are occasionally fed by the branch of the internal carotid artery.MethodsIn RADPLAT for maxillary sinus cancer partly fed by the ophthalmic artery, the ethmoid arteries were ligated in two patients without medial orbital wall involvement. In four patients with that, CDDP was administered via the ophthalmic artery.ResultsA complete response was obtained in all six patients. Locoregional recurrence was not observed in any cases. However, visual acuity was lost in four patients who received the ophthalmic artery infusion.ConclusionsLigation of the ethmoid arteries is recommended in RADPLAT for maxillary sinus cancer with lesions fed by the ophthalmic artery. CDDP administered via the ophthalmic artery may be considered if a patient accepts the possibility of visual loss.
