Patients and methods
Consecutive patients with AVM referred to the Centre for the Study and Treatment of Vascular Birthmarks during 1996–2010 were culled from our prospective Vascular Anomalies Database comprising 1131 patients from within New Zealand and the South Pacific. All patients were assessed and followed up by our multidisciplinary team. The medical records of these patients with AVM were reviewed to supplement the data collected which included sex, age at presentation, anatomical location, symptoms,
Results
Fifty-three consecutive patients (22 males, 31 females) with the diagnosis of AVM were culled from the Vascular Anomalies Database. They represented 4.7% of the 1131 patients with vascular anomalies referred to our Vascular Anomalies Centre over a 14-year period. The mean age of presentation was 29 (range: 3–88) years. The primary location of the AVM was in the head and neck region (n = 32), lower limb (n = 13), upper limb (n = 7) and trunk (n = 1). Affected head and neck sub-sites included the ear (n =
Discussion
AVM is a relatively rare condition consisting of 4.6% of all patients referred to our Vascular Anomalies Centre. Our data confirm that AVMs present most commonly in the head and neck area followed by the upper and lower limb with a predilection for the periphery (i.e., hands and feet).2 Solitary AVMs primarily involving the trunk are uncommon; AVM usually affects the soft tissues. Consistent with a previous report,2 our study shows that the mandible, the facial bone, is the most commonly

AVMs are diagnosed according to history and clinical examination, combined with imaging characteristics.
