Arterio-venous fistula of the ear

Abstract

A CASE of congenital arterio-venous fistula involving the external ear in a 33-year-old female patient is described in this paper. She presented to the hospital with severe haemorrhage from the swelling over the ear necessitating immediate admission into hospital and transfusion of whole blood. The treatment of the case is described in detail. She is alive and well 3 years after her definitive treatment.

Auricular Arteriovenous Malformation: Evaluation, Management, and Outcome

“…1,3,6,7 The typical history was a macular cutaneous blush, or "vascular birthmark" noted in early infancy (Schobinger stage I). 1,7 Increased warmth and slight size discrepancy between the ears were observed as well but were usually underappreciated by the pediatrician and parents.…”

“…Trauma could also act as a trigger, as noted in previous reports. 1,3,10 Curiously, none of the female patients who were taking oral contraceptives noticed worsening signs or symptoms.…”

“…) Arteriovenous malformation outside the cranium is rare; however, the ear is the second most common location in the head and neck. 1 Auricular arteriovenous malformation has been the subject of single case reports [2][3][4][5][6] or small series. 7,8 Often, these anomalies are included in large series of head and neck arteriovenous malformation.…”

Challenges of Management of Arteriovenous Malformation of the Pinna in a Low Resource Setting: A Case Report

“…The highest level of research on this subject is a few case series and case reports [2] [3] [4]. As such recommendations on management are based on experiences of surgeons who have managed these cases at one point or the other [5] [6]. We present a 17-year-old female who had both clinical and radiological diagnosis of a Schobinger stage III AVM of the left pinna and was managed surgically with no recurrence at one year follow up.…”
