Calibre Persistent Labial Artery of the Lower Lip: Oral Propranolol as a Novel Agent of Treatment

Abstract

Calibre persistent artery of the lower lip is a vascular anomaly where the branches of the inferior labial artery maintain their size up to the submucosa of the lip. There is persistent pulsatile feeling, occasional ulceration, and recurrent bleeding. Doppler ultrasound and angiogram are used to confirm diagnosis. Before this case report, treatment of this condition has been surgical excision. We document the successful treatment with oral propranolol.
