Pulmonary arteriovenous malformations (PAVMs) are a rare
clinical entity. Most of them are associated with hereditary
haemorrhagic telangiectasia. The usual clinical presentation is
exertional dyspnoea and hypoxaemia. The initial test of choice for
screening is the 100% oxygen method. A pulmonary angiogram is needed
to define the anatomy and guide transcatheter embolisation (TCE). TCE
has been shown to be effective and safe with a very low recanalisation rate and has largely replaced surgery for PAVMs. Computed tomography of
the chest can be used for the follow up of asymptomatic PAVMs and TCE.
