Two Cases of Lingual Arteriovenous Malformations with Comorbidities Treated by Glue Embolization: A Report with Review of Literature.

Arteriovenous malformations (AVMs) involving the tongue are uncommon lesions in the head and neck region. They present with bleeding that can be massive and life-threatening apart from debilitating symptoms of pain, ulcers, difficulty in phonation or swallowing. Various therapeutic approaches have been used in their management-surgery, endovascular embolization, radiation and ablation procedures like laser ablation. We report two patients-a 34 year-old man and 56 year-old female who presented with massive bleeding due to lingual AVM and had comorbidities as liver cirrhosis and chronic medical renal disease respectively, and treated with glue embolization, with a review of the literature. © Association of Otolaryngologists of India 2018.
