Pulmonary arteriovenous fistula within a pulmonary cyst - evaluation with CT pulmonary angiography.
Pulmonary arteriovenous malformations (PAVMs) are abnormal direct communications between pulmonary arteries and pulmonary veins. These abnormal communications result in an anatomical right-to-left shunt that reduces the arterial oxygen saturation and may cause hypoxaemia and dyspnoea. Although PAVMs frequently remain undiagnosed, they are associated with severe morbidity in the form of ischaemi...

They may occur as isolated entities or associated with Osler-Rendu-Weber syndrome or hereditary haemorrhagic telangiectasia (HHT). We study 3 patients with Rendu-OslerWeber disease and a large arteriovenous malformation inv...
