Ultra-high pre-membrane lung oxygen saturation in a patient on veno-arterial extracorporeal membrane oxygenation

Abstract

A 55-year-old man who suffered from acute myocardial infarction complicated with cardiogenic shock was administered veno-arterial extracorporeal membrane oxygenation. Ultra-high pre-membrane lung oxygen saturation of 93% was observed. Transthoracic echocardiography revealed the presence of patent foramen ovale. The four-chamber view showed that the tip of the cannula was located in the patent foramen ovale, which resulted in a left-to-right shunt. Without adjusting the position of the drainage cannula, the patient was weaned from extracorporeal membrane oxygenation at 136 hours after initiation and survived to hospital discharge.

Use of venous-venous extracorporeal membrane oxygenation in the treatment of postpartum pulmonary hypertension crisis

“…4,5 Extracorporeal membrane oxygenation (ECMO) is widely used in critically ill patients with cardiopulmonary failure. 6 ECMO is regarded as an important treatment for critically ill women with PH or ES, but the best modality for patients with PH is still uncertain. [7][8][9][10] In this case report, a ventricular septal defect (VSD) in a pregnant woman with PH and ES, which is a pulmonary hypertension crisis that occurs after delivery and results in respiratory and circulatory disturbances, was successfully managed after using ECMO.…”
