FLORES HERNANDEZ, Salomón Sergio; GONZALEZ ZAMORA, José Francisco; CARRASCO DAZA, Daniel  and  GONZALEZ FLORES, María de Lourdes. Arteriovenous malformation of the lung in a fourteen year old girl. Rev. Inst. Nal. Enf. Resp. Mex. [online]. 2006, vol.19, n.1, pp.47-50. ISSN 0187-7585.

Pulmonary arteriovenous malformations (PVAM) are abnormal communications between pulmonary arteries and pulmonary veins, which are more commonly congenital in nature. Pulmonary arteriovenous fistulae are characterized by right-to-left shunts of variable magnitude; the effect of these communications depends on the size of the vessels involved. Arterial oxygen desaturation, cyanosis, clubbing of the fingers, and polycythemia may occur, secondary to the intrapulmonary shunt. We report the case of a 14-year-old female patient with PA VM; the findings on physical examination were clubbing of her fingers and cyanosis.

Keywords : Cyanosis; hypoxemia; pulmonary arteriovenous malformation.
