The portal venous-esophageal luminal pressure gradient may be more important than the absolute portal venous pressure in explaining hemorrhages caused by esophageal varices. A continuous recording of portal venous pressure and the esophageal luminal pressure enabled the authors to study the gradient between these pressures in 12 cirrhotic patients with varices of different size and under different circumstances, in particular inspiration, expiration, coughing and a Valsalva maneuver.
A significant increase of portal venous pressure occurred during inspiration (+15%), coughing (+77%) and Valsalva maneuver (+157%). The value of portal venous-esophageal luminal pressure gradient increased during inspiration (+38%), coughing (+90%) and Valsalva maneuver (+69%) while it decreased during expiration (–14%).
