[Pulmonary alveolar microlithiasis. Study of pulmonary circulation].
Pulmonary alveolar microlithiasis is a rare disease of unknown etiology which consists of alveolar deposit of calcium microspheres. We report the procedures for the diagnosis of this disease, as well as the hemodynamic features of the pulmonary circulation. Pulmonary arterial hypertension (PAH), and cor pulmonale were documented. The active and passive factors involved in PAH are analyzed. We conclude that alveolar hypoxia and estructural vascular changes play a major role in the genesis of PAH.
