Official Title: Assessment of Portal Flow Using Bedside Doppler Ultrasonography for the Detection of Portal Pulsatility as a Risk Factor for Acute Kidney Injury in Cardiac Surgery Patients
Brief Summary: The purpose of this study is to evaluate the possible association between portal vein flow pulsatility and acute kidney injury after cardiac surgery. Participants will undergo assessment of portal vein flow and intra-renal blood flow using bedside Doppler ultrasound before surgery and daily for three days after cardiac surgery.
