Peripheral extracorporeal membrane oxygenation with interposition graft. the outflow is highly dependent on the anastomotic angle

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is a technique that supports vital functions through extracorporeal circulation, by raising blood oxygenation, reducing blood carbon dioxide values (CO2), increasing cardiac output and acting on body temperature. In conditions of severe respiratory and/or cardiac insufficiency, it allows to put the heart and lungs at rest by compensating for their ventilatory and pump functions. The correct distribution of blood flows between the upper and lower parts of the body is of considerable importance to avoid the onset of serious diseases in the patient. This study presents a mathematical model for the analysis of blood flows according to the configuration of the connection between the ECMO system and the vascular system.
