Diurnal fluctuations of portal and systemic hemodynamic parameters in patients with cirrhosis
Daniel Alvarez, Diego Golombek, Patricia Lopez, Marcelo De Las Heras, Luis Viola, Susana Sanchez, Miguel Kolker, Ricardo Mastai – 1 November 1994 – A close temporal relationship between higher levels of portal pressure during the night and the peak incidence of acute variceal bleeding has recently been demonstrated in patients with cirrhosis. Because hemodynamic changes may have a role in triggering this hemorrhagic episode, we measured systemic and portal hemodynamic parameters at 4‐hr intervals for 24 hr in 12 cirrhotic patients.
