[Asymmetric pulmonary perfusion causing unilateral pulmonary edema as a complication of acute myocardial infarction]. / Perfusión pulmonar asimétrica como causa de edema agudo de pulmón unilateral complicando un infarto agudo de miocardio.

Acute unilateral pulmonary edema is an unusual clinical condition occasionally associated with severe mitral valve insufficiency. We describe a patient diagnosed as having unilateral pulmonary edema after an acute anterior myocardial infarction. Echocardiograms performed in the acute phase ruled out mitral insufficiency. A perfusion lung scan showed left-sided pulmonary hypoperfusion. The diagnosis of acquired hypoplasia of the left pulmonary artery tree was made by chest computed tomography. The pathogenesis and differential diagnosis are discussed.

El edema agudo de pulmón unilateral es una entidad infrecuente que en ocasiones se ha asociado con la presencia de insuficiencia mitral severa. Presentamos el caso de un paciente que, tras presentar un infarto agudo de miocardio anterior, presenta un edema agudo de pulmón unilateral. En los ecocardiogramas realizados en la fase aguda se descartó la presencia de insuficiencia mitral. La gammagrafía de perfusión pulmonar mostró una hipoperfusión generalizada del pulmón izquierdo. Se diagnosticó una hipoplasia adquirida del árbol arterial pulmonar izquierdo mediante tomografía computarizada torácica. Se discuten la patogenia y el diagnóstico diferencial
