A NEW WAY TO DETECT ACUTE KIDNEY INJURY

The aim is to prospectively evaluate the association between the ultrasound score (VEXUS) and the occurrence of acute renal failure post-operatively following cardiac surgery. The VEXUS (Venous Excess UltraSound) score is an ultrasound tool used in medicine to assess systemic venous congestion, i.e. excess pressure in the venous system linked to volume overload or right heart failure. The VEXUS score relies on ultrasound of the inferior vena cava (IVC) to assess the extent of congestion in this vein. score 0 : Normal IVC + Normal Dopplers; score 1 : Dilated IVC + altered hepatic venous Doppler, but normal portal vein; score 2 : Portal vein shows significant pulsatility; score 3 : Severe pulsatility + marked alteration of hepatic and portal flow
