| Popis: | Passive hepatic congestion is caused by stasis of blood within the liver parenchyma due to compromise of hepatic venous drainage. It is a common complication of congestive heart failure and constrictive pericarditis, wherein elevated central venous pressure is directly transmitted from the right atrium to the hepatic veins because of their close anatomic relationship (Fig. 1). The liver becomes tensely swollen as the hepatic sinusoids dilate and engorge to accommodate the backflow of blood. A variety of structural and functional hepatic derangements develop that have distinctive appearances on sonograms, CT scans, and MR images. |
