Acute Pulmonary Edema Following Cardiopulmonary Bypass: A Case Report

Abstract

Background: Acute pulmonary edema following cardiopulmonary bypass (CPB) is a serious complication, the etiology of which could be classified into two groups: cardiogenic and noncardiogenic. Case presentation: We present a 42-year-old male with multiple pulmonary bullae scheduled for mitral valve and aortic valve replacement. Acute pulmonary edema occurred approximately 1 hour after weaning from CPB. The diagnosis of non-cardiogenic pulmonary edema was established with changes in pathophysiology and findings on ultrasound. The patient was promptly treated and transferred to the ICU uneventfully. Conclusions: This case report highlights the changes in pathophysiology combined with ultrasound findings to establish a diagnosis in the operating room. We also emphasize the perioperative management of noncardiogenic pulmonary edema.
