Bilateral pulmonary emboli presenting as platypnea-orthodeoxia.
Pak Heart J Jan ;47(3):162-4.

We are reporting a case of 78 yrs old female presented with platypnea-orthodeoxia,likely caused by bilateral proximal pulmonary emboli. Despite appropriate treatment, she died of respiratory arrest. It is uncommon to have clinical evaluation of platypnea and appropriate documentation of orthodeoxia. Platypnea-orthodeoxia can be a rare but presenting feature of massive pulmonary emboli. Clinicians should have a high index of suspicion, in at risk individuals with refractory hypoxia, prompt evaluation of which may lead to improve outcome.
