CONGESTIVE HEPATOPATHY PDF

Prolonged exposure to elevated hepatic venous pressure may lead to liver fibrosis and cirrhosis. Liver dysfunction and corresponding clinical signs and symptoms typically manifest late in the disease process. Recognition of CH at imaging is critical because advanced liver fibrosis may develop before the condition is suspected clinically. Characteristic findings of CH on conventional images include dilatation of the inferior vena cava and hepatic veins; retrograde hepatic venous opacification during the early bolus phase of intravenous contrast material injection; and a predominantly peripheral heterogeneous pattern of hepatic enhancement due to stagnant blood flow. Extensive fibrosis can be seen in chronic or severe cases.

Prolonged exposure to elevated hepatic venous pressure may lead to liver fibrosis and cirrhosis. Liver dysfunction and corresponding clinical signs and symptoms typically manifest late in the disease process.

Recognition of CH at imaging is critical because advanced liver fibrosis may develop before the condition is suspected clinically. Characteristic findings of CH on conventional images include dilatation of the inferior vena cava and hepatic veins; retrograde hepatic venous opacification during the early bolus phase of intravenous contrast material injection; and a predominantly peripheral heterogeneous pattern of hepatic enhancement due to stagnant blood flow. Extensive fibrosis can be seen in chronic or severe cases.

Hyperenhancing regenerative nodules that may retain hepatobiliary contrast agents are often present. Magnetic resonance MR elastography can show elevated liver stiffness and may be useful in evaluation of fibrosis in CH because it can be incorporated easily into routine cardiac MR imaging. Preliminary experience with MR elastography suggests its future use in initial evaluation of patients suspected of having CH, for monitoring of disease, and for assessment after therapy. To facilitate appropriate workup and treatment, radiologists should be familiar with findings suggestive of CH at radiography, ultrasonography, computed tomography, MR imaging, and MR elastography.

In addition, knowledge of underlying pathophysiology, comparative histologic abnormalities, and extrahepatic manifestations is useful to avoid diagnostic pitfalls and suggest appropriate additional diagnostic testing.

AB - Congestive hepatopathy CH refers to hepatic abnormalities that result from passive hepatic venous congestion.

Congestive hepatopathy

In addition to the heart or lung symptoms, there will be a sense of fullness and tenderness in the right hypochondriac region. Gastrointestinal catarrh is usually present, and vomiting of blood may occur. There is usually more or less jaundice. Owing to portal obstruction, ascites occurs, followed later by generalised oedema. The stools are light or clay-colored, and the urine is colored by bile.

Congestive Hepatopathy

Portal venule central vein distension. Perisinusoidal fibrosis - progresses to centrilobular fibrosis and then diffuse fibrosis. Dilation of sinusoids in all zone III areas - key feature. Cardiac congestive hepatopathy, wherein outflow obstruction occurs secondary to backflow from a failing heart, and Budd Chiari syndrome, wherein obstruction of outflow occurs secondary to obstruction, usually thrombotic, have overlapping features, including sinusoidal dilation with emphasis upon the central vein, space of Disse erythrocytes, centrilobular inflammation, hemorrhage, bile ductules, and hemosiderin, and portal inflammation, fibrosis and bile ductular reaction. In end stage liver, fibrosis for cardiac hepatopathy comprises stellate centrizonal fibrous with haphazard spread, as opposed to the more frequent nodular cirrhosis in Budd-Chiari.
