Excerpt

In bifemoral venoarterial extracorporeal membrane oxygenation (VA ECMO), the transition point at which the antegrade pulsatile output from the left ventricle and the retrograde non-pulsatile ECMO output collide is referred to as watershed [1]. Currently, no standard method is available to determine its location. Occasionally, contrast-enhanced computed tomography (CT) or angiography has been used [1‐3]. Both techniques, however, bear disadvantages including radiation exposure and use of iodinated contrast media. We assessed the feasibility and safety of contrast-enhanced ultrasound (CEUS) to detect the watershed at the bedside in patients on bifemoral VA ECMO at three ICUs of a European tertiary care facility. …
