Postoperative acute kidney injury and renal replacement therapy after DCD lung transplantation.

Acute kidney injury (AKI) after lung transplantation (LTx) is a common complication. We aimed to assess whether donation after circulatory death (DCD) is associated with an increased risk of AKI and renal replacement therapy (RRT) in the early postoperative period compared to the donation after brain death (DBD). Retrospective data on a cohort (N = 95) of LTx patients (DCD n = 17, DBD n = 78) characterized by no use of ex-vivo lung perfusion were analyzed for the incidence of AKI within 30 postoperative days and incidence of RRT within 7 and 30 days.

Valvular complications following the Impella device implantation.

Background: Despite clear clinical benefits, there is limited evidence regarding possible complications of the novel mechanical support device Impella. Aortic and mitral valve regurgitation or injury are rare but potential complications following implantation of the Impella device.

Methods: To evaluate valvular complications after the Impella device implantation, we have performed a comprehensive search of literature on multiple sites on this topic.

Veno-arterial mechanical support as bridge to surgery in a patient with severe aortic regurgitation: a case report.

In this case report, we describe the successful application of veno-arterial extracorporeal membrane oxygenation support in a young patient with severe aortic regurgitation caused by a blocked mechanical valve. In this situation, extracorporeal membrane oxygenation mechanical support was used as a bridge to the prompt replacement of the diseased valve. Aortic regurgitation is commonly recognized as a contraindication to extracorporeal membrane oxygenation support because of the risk of ventricular distension, pulmonary oedema and further organ failure.
