Abstract
The plathypnea orthodeoxia syndrome is a rare condition that is characterized by dyspnea and hypoxia that occurs in the upright position and improves with recumbency. The diagnostic is often made tardively and requires the combination of two components: a mechanical one (for example a patent foramen ovale) and a kinetic one (for example COPD). This combination contributes to the blood flow through the communication. The treatment consists of closing the veno-arterial communication (in the case of a patent foramen ovale, the closing of the inter-atrial septum) (Knapper et al, 2014). In the present article, we describe two severe hypoxemic patients suffering from this syndrome. Both cases were associated with an acute pulmonary disease. A review of the literature is performed.
