[Pulmonary arteriovenous fistula. A rare cause of dyspnea and cyanosis in an adult].
The authors report the case of a pulmonary arteriovenous fistula presenting with dyspnoea and cyanosis in a young adult. The malformation was situated on the proximal pulmonary vessels and was cured by surgical correction. The diagnostic value of the clinical signs and complementary investigations of this rare conditions, often detected during adulthood, is discussed. The functional tolerance of the condition is often variable. Oxygen desaturation of arterial blood indicates a right-to-left shunt. Pulmonary angiography enables visualisation of the lesions and guides surgical management. The prevalence of complications of this condition is not well known, but the potential severity is an argument for therapeutic intervention. Embolisation techniques are developing but there is a risk of a systemic embolism. Surgery is the reference for the treatment of proximal fistulae, its curative effect being immediate and definitive.
