High Flow AV Malformation (A-V Shunt) of Mandible: A Rare Life Threatening Entity

Sanat Kumar Bhuyan et al. J Clin Diagn Res. 2016 Nov.

Abstract

Intraosseous Arteriovenous Malformations (AVMs) in the head and neck region are very rare and potentially life threatening entities due to massive hemorrhage. These are the results of an embryonic abnormality of the vascular system. Depending on the blood flow and clinical presentations they are of different types like slow flow and high flow AVM. Here we present a case of high flow AVM involving mandible with a chief complain of gingival bleeding in a four year old girl child.

Keywords: Girl child; Intraosseous lesion; Jaw bones; Vascular malformations.
