Edema pulmonar relámpago, flash pulmonary edema: cuando el riñón descompensa al corazón / Flash pulmonary edema, report of 2 cases

ABSTRACT

Flash pulmonary edema is a paroxismal pulmonary edema associated to a hypertensive crisis, that subsides in hours with the usual therapeutic measures. It occurs in patients with renal artery stenosis. We report two male patients aged 71 and 74 years old, presenting with acute dyspnea and high blood pressure. Diffuse rales were auscultated and arterial blood pressure was high in both. Dyspnea subsided in few hours with diuretics and oxygen. In both, a critical renal arterial stenosis was found and an angioplasty with stent placement was performed. After 5 and 6 months of follow up, the patients remain asymptomatic
