  • Title: [Osteoiliacography as diagnostic method of vena cava inferior circulation failure in liver cirrhosis].
    Author: Turmakhanov ST.
    Journal: Vestn Khir Im I I Grek; 2012; 171(3):20-3. PubMed ID: 22880426.
    Abstract:
    Hypertension developing in the vena cava system under conditions of cirrhosis results in the formation of collateral blood outflow into vena cava superior (VCS) and inferior, at the same time the carrying capacity of vena cava inferior (VCI) might be limited due both to its fixation in the rigid diaphragm ring and to the fact that the hepatic segment of VCI is compressed by regenerated nodes. The increased volume of blood outflow via VCI with a simultaneous constriction of its hepatic segment results in the development of caval hypertention which even more complicates the transhepatic blood flow. Increased pressure in the VCI system with the formation of suprahepatic postsinusoidal block creates additional considerable barriers for blood outflow from the liver aggravating the failure of portal circulation, creating vicious circle that leads to decompensation of both regional visceral and common venous hemodynamics. The author describes the method of diagnosing cava-caval crossflows from VCI to VCS. The condition of VCI and cava-caval crossflows under liver cirrhosis is an important component in complex diagnostics.
