ABSTRACT
Extracorporeal membrane oxygenation (ECMO) could pump the blood from human veins to the outside of the body, oxygenate the red blood cells in an artificial environment and then return them back into the body. ECMO could replace the heart and lungs to complete gas exchange and systemic blood perfusion in patients with severe cardiopulmonary insufficiency, which also plays an important role in the field of heart transplantation. Besides circulatory support treatment after heart transplantation, ECMO may also be used to prolong the waiting time for heart transplantation in patients with respiratory and circulatory failure before operation, as a bridging therapy for heart transplantation. However, at present, the application of ECMO in pediatric heart transplantation still exist challenges, such as high perioperative mortality and difficulty in determining the timing of treatment, etc. In this article, the development history of ECMO application in pediatric heart transplantation, use of ECMO before and after pediatric heart transplantation, ECMO-related complications in children, and application of ventricular assist device (VAD) in pediatric heart transplantation were briefly reviewed, aiming to provide reference for promoting the application of ECMO in pediatric heart transplantation.
ABSTRACT
@#Central venous stenosis is a common complication following long-term dialysis catheter placement in dialysis patients. Generally, percutaneous angioplasty is the treatment of choice, and venous stent implantation should be considered in different situations. However, the venous stent migrating into right atrium is a rare but fatal complication. We presented a patient whose superior vena cava stents migrated into right atrium, resulting in acute tamponade, and exploratory thoracotomy was proceeded.
