Retrograde Intra-arterial Infusion of Prostaglandin El and Heparin for the No-reflow Phenomenon After Oromandibular Reconstruction with a Free Fibular Flap

Abstract

The authors encountered a patient with a tumor of the floor of the mouth in whom the no-reflow phenomenon occurred after excision of the lesion and the mandible, followed by reconstruction using a free fibular flap. A catheter was inserted retrogradely from the point where the peroneal artery had been ligated at the time of flap preparation. Continuous intra-arterial infusion of prostaglandin E1 and heparin was performed, and the flap survived. This method salvaged free flaps subject to the no-reflow phenomenon.
