Caudate lobe hypertrophy in Budd Chiari

Huge caudate lobe of the liver due to Budd-Chiari syndrom

  1. Budd-Chiari syndrome is characterized by hepatic venous outflow obstruction. We describe a patient with a huge caudate lobe of the liver due to Budd-Chiari syndrome. A 49-year-old woman was referred to Nippon Medical School Hospital to receive treatment for enlarged gastric varices. She had been fol
  2. Five cases showed the classic scintigraphic pattern of caudate lobe hypertrophy (62.5%), and other abnormalities observed included segmental hepatic insufficiency, diffuse hepatic insufficiency, and relative hypertrophy of both the caudate lobe and a portion of the parenchyma of segment VI (one case each)
  3. The compensatory hypertrophy of the caudate lobe is explained by preservation of its veins draining directly into the inferior vena cava . Typical microscopic features of Budd-Chiari syndrome include centrilobular congestion, sinusoidal dilatation, fibrosis, necrosis, and cell atrophy
  4. Similarly, the mechanism of caudate lobe hypertrophy in Budd-Chiari syndrome remains unclear, although it could be related to the fact that the caudate lobe would allow blood to be drained through a hypertrophied caudate vein. In our study, the differences in the size of the caudate lobe in the two subgroups of patients with Budd-Chiari.
  5. We present a comprehensive description of sonomorphological signs in BCS. The combination of ultrasound signs altered hepatic and/or caval veins and caudate lobe hypertrophy was the best strategy to diagnose BCS. Patients with portal vein thrombosis or portal hypertension have a poor prognosis
  6. al hypertension (IAH), caused by severe ascites, HVOO may aggravate the cardiovascular disturbances seen in patients with.

Hypertrophy of the caudate lobe, irregularities of the liver contour, and regenerative nodules are prominent features of chronic Budd-Chiari syndrome (, 51 55 56) (, Fig 5,). Figure 5a. Contrast-enhanced helical CT images from late hepatic arterial phase imaging in a 47-year-old man with Budd-Chiari syndrome show multiple regenerative. The caudate lobe veins may be dilated. 30 The IVC may be narrowed, may be shifted to the right secondary to caudate lobe hypertrophy, or may demonstrate intraluminal thrombus. Color-flow duplex ultrasound may be used to evaluate flow characteristics and direction. Budd-Chiari syndrome secondary to blunt abdominal trauma in a 6-year-old. Budd-Chiari syndrome, also known as hepatic venous outflow obstruction (HVOO), refers to the clinical picture that occurs when there is partial or complete obstruction of the hepatic veins.. There is no clear consensus regarding the number of occluded veins, some authors claim that there should be at least one occluded hepatic vein 7, others state that there are no significant hemodynamic.

Budd-Chiari syndrome is characterized by hepatic venous outflow obstruction. We describe a patient with a huge caudate lobe of the liver due to Budd-Chiari syndrome. A 49-year-old woman was. Caudate lobe enlargement is often present. The majority of patients have a slower-onset form of Budd-Chiari syndrome. This can be painless. A system of venous collaterals may form around the occlusion which may be seen on imaging as a spider's web. Patients may progress to cirrhosis and show the signs of liver failure chronic phase of Budd-Chiari syndrome, the liver is dysmorphic, with caudate lobe hypertrophy (ratio of caudate lobe width to right lobe width, ≥ 0.55:1) and atrophy of the peripheral segments (3). The IVC and hepatic veins often are not vis-ible because of collapse or a diminished flow rate. At contrast-enhanced CT of acute phas

Diagram of hepatic venous drainage depicts the small veins that drain from the caudate lobe and adjacent part of the right lobe directly into the inferior vena cava. The veins tend to be spared in hepatic venous occlusion in patients with Budd-Chiari syndrome, giving rise to hypertrophy of the caudate lobe and adjacent part of the right lobe collateralization (marked black arrows in a), caudate lobe hypertrophy (white asterisk in b) and markedly atrophied left hepatic lobe. The middle hepatic vein is well Occasionally, the IVC is narrowed by extrinsic compression from caudate lobe hypertrophy. In this situation, restoration of hepatic outflow alone may restore IVC flow. In 15% of patients. In the patient described above, caudate lobe hypertrophy was prominent and mimicked the presence of a caudate lobe neoplasm. The use of oral contraceptive drugs appears to increase the risk of Budd‐Chiari syndrome by a factor of 2 but most patients also have a coexisting thrombogenic disorder

DIAGNOSTIC CHECKLIST. (Left) Axial anatomic illustration of Budd-Chiari syndrome demonstrates ascites, venous collaterals , heterogeneous hepatic parenchyma due to centrilobular necrosis, and hypervascular regenerative nodules . Note the sparing of the caudate lobe with hypertrophy , as well as the thrombosed IVC The hypertrophy of the central parts of the liver (mainly the caudate lobe) is another feature suggesting BCS, but it is not specific for this disease. Nowadays, invasive procedures such as liver biopsy and X-ray venography are needed only in patients where the diagnosis remains uncertain after noninvasive imaging. 1 ,

The Caudate Lobe is located between the left lobe of the liver and the inferior vena cava. Unlike the liver's other lobes, the caudate lobe is directly connected to the IVC through small veins, known as heptic veins, which move deoxygenated blood. These veins are separate from the main heptic veins in the liver 1. Diagnosis of Budd-Chiari syndrome can be made on the basis of radiological imaging alone without the need for liver biopsy. 2. Ultrasonography, computed tomography, and mag-netic resonance imaging all show various degrees of occlusion of the hepatic veins and/or inferior vena cava. Hypertrophy of the caudate lobe may also be seen. 3 1. Diagnosis of Budd-Chiari syndrome can be made on the basis of radiological imaging alone without the need for liver biopsy. 2. Ultrasonography, computed tomography, and magnetic resonance imaging all show various degrees of occlusion of the hepatic veins and/or inferior vena cava. Hypertrophy of the caudate lobe may also be seen. 3

Budd-Chiari syndrome Presents with - acute or chronic form. acute - results from an acute thrombosis of the hepatic veins or the IVC Chronic form is related to fibrosis of the intrahepatic veins. 11. Ultrasound findings Enlargement of the caudate lobe Budd-Chiari syndrome is defined as an obstruction of the venous outflow from the sinusoidal bed of the liver. It leads to portal hypertension, ascites and progressive hepatic failure [57].. The treatment of Budd-Chiari syndrome depends on the cause of the obstruction and, hence, careful examination of the hepatic veins, the inferior caval vein (ICV) and the right atrium is necessary [37, 73] Caudate lobe hypertrophy was present in only six cases. US study is therefore the procedure of choice for mitial diagnosis of acute Budd-Chiari syndrome. Pitfalls were the failure to detect two caval thromboses and one hepatic vein web BCS / Caudate lobe hypertrophy Erden A. Eur J Radiol 2007 ; 61 : 44 - 56.

Budd-Chiari syndrome: typical and atypical scintigraphic

Budd-Chiari syndrome (BCS) is an uncommon vascular disorder in which venous thrombosis prevents the venous outflow of the liver. The obstruction is primarily at the level of hepatic veins and inferior vena cava. Here, we present a case of a two-and-a-half-year-old male child who presented with complaints of abdominal distension for two months and fever and watery diarrhea for one month (Left) Axial anatomic illustration of Budd-Chiari syndrome demonstrates ascites, venous collaterals , heterogeneous hepatic parenchyma due to centrilobular necrosis, and hypervascular regenerative nodules .Note the sparing of the caudate lobe with hypertrophy , as well as the thrombosed IVC Caudate lobe enlargement can be seen in cases of Budd-Chiari syndrome, as well as cirrhosis. the sonographer was asked to perform an abdominal sonogram to rule out cirrhosis in a patient with a history of alcohol abuse As indicated above caudate lobe hypertrophy is common in Budd-Chiari Syndrome and the enlarged caudate lobe may compress the inferior vena cava resulting in increase in pressure in its infra hepatic portion. This pressure may even exceed that found in the portal vein so that decompression of the portal venous system into the inferior vena cava.

Budd-Chiari Syndrome: Spectrum of Imaging Findings

Computed tomography (CT) showed hepatomegaly with caudate lobe hypertrophy, ascites and occlusion of the right hepatic vein, suggestive of Budd-Chiari syndrome. Laboratory evaluation on admission demonstrated elevated liver enzymes (AST 130 IU/L, ALT 108 IU/L, total bilirubin 2.2 mg/dL, direct bilirubin 1.3 mg/dL, γ-GT 74 IU/L) and. MRI showed a collapsed inferior vena cava, as well as signal intensity changes in the hepatic segments and caudate lobe hypertrophy. The hepatic veins were still not visualised, confirming the absent flow in these structures. Clinical data and imaging findings indicated Budd-Chiari syndrome secondary to polycythaemia vera The caudate vein not only receives blood from the caudate lobe, but also from other parts of the liver through collateral pathways, causing caudate lobe enlargement and caudate vein dilation , , . Bargalló et al. [5] evaluated the diagnostic value of the caudate vein in Budd-Chiari syndrome by color Doppler ultrasound, and noted the caudate. caudate lobe hypertrophy: long term: medium: This condition occurs as a compensatory mechanism, as the caudate lobe has a direct venous drainage into the inferior vena cava (IVC). It results in compression and stenosis of the IVC, further contributing to existing venous congestion

caudate lobe enlargement is seen in 80-91% of all cases.16,17 Vascular changes A recent thrombus is hypoechoic on ultrasound and leads to expansion of the lumen of the involved HVs. 17 It produces signal void on Doppler ultrasound. Over a few days, the thrombus becomes echogenic with retraction of the lumen of the involve The most common lobe affected in Budd-Chiari syndrome is the caudate lobe because its blood is directly shunted into the inferior vena cava. Hence, when the hepatic veins are occluded, the caudate lobe undergoes hypertrophy. Histopathology. Biopsy of the liver of the patient suffering from Budd-Chiari syndrome shows the following features Budd Chiari syndrome (BCS) is a rare disorder that results from hepatic venous outflow tract obstruction, occurring anywhere from the small hepatic veins to the suprahepatic are hepatomegaly and caudate lobe hypertrophy. 6 Although US, CT and MRI are commonly used to diagnose BCS, th In conditions such as cirrhosis, Budd-Chiari syndrome or primary sclerosing cholangitis the liver may be dysmorphic in appearance. In the chronic phase of Budd-Chiari syndrome, the abnormal vascularization tends to be located more peripherally and to be most prominent around the caudate lobe due to its separate autonomous venous drainage

Caudate Lobe Hypertrophy; Hepatocellular Carcinoma; Portal Vein Thrombosis (PVT) Budd-Chiari Syndrome Life Expectancy. If left untreated, BCS can turn into a potentially fatal condition. The mortality rate reported in sufferers of the condition is around 80%. The life expectancy varies according to the degree of vein blockage Caudate lobe hypertrophy is a salient feature. Obstruction at the level of hepatic veins may be manifested by ostial narrowing, echogenic thrombus, and altered flow patterns in the form of turbulent flow, nonvisualization of the veins, or reversal of flow.

Enlargement of the caudate lobe. Small veins that drain the caudate lobe directly into the IVC tend not to be affected in patients with Budd-Chiari syndrome. This explains the enlargement and hypertrophy of the segment I of the liver (caudate lobe) Whether there is significant caval compression secondary to caudate lobe hypertrophy. If present, a standard portocaval (infrahepatic) shunt will not reduce hepatic congestion, and a mesoatrial (suprahepatic) shunt is required, unless the cava is stented beforehand. As Budd-Chiari syndrome is a postsinusoidal condition, a successful shunt. Fig. 1.

The axial venous phase images acquired at various levels (a, b & c) show extensive portosystemic collateralization (marked black arrows in a), caudate lobe hypertrophy (white asterisk in b) and markedly atrophied left hepatic lobe. The middle hepatic vein is well Budd-Chiari syndrome. Budd-Chiari syndrome is characterized by hypertrophy of the caudate lobe and variable atrophy/hypertrophy of the remaining portions of the liver. Focal nodular regenerative hyperplasia has been primarily reported in long-standing Budd-Chiari syndrome. Pseudocirrhosi The portarenal shunt has been described in five patients with Budd-Chiari syndrome over the past 30 years, so it is rarely used. There is no doubt that direct side-to-side portacaval shunt is the procedure of choice in uncomplicated Budd-Chiari syndrome, even in patients with hypertrophy of the caudate lobe patients with Budd-Chiari syndrome over the past 30 years, so it is rarely used.

Nonspecific findings include caudate lobe hypertrophy, inhomogeneous liver parenchyma, extrahepatic collaterals, portal vein thrombosis, and regenerative nodules as well as ascites. The combination of specific signs and caudate lobe hypertrophy has the highest predictive value to identify patients with BCS Introduction. Budd-Chiari syndrome (BCS) is a rare disorder caused by hepatic venous outflow obstruction with a wide wide range of aetiologies. Clinical manifestations are so varied that the diagnosis should be considered in any patients with acute or chronic liver disease [].It should be differentiated from veno-occlusive disease in which the sinusoidal epithelial cells of the hepatic venules. On imaging, pathognomic features are enlarged caudate lobe in a majority of chronic BCS cases, caused by compensatory hypertrophy due to its direct venous drainage into the IVC. Non-visualisation of HVs, particularly in chronic cases, is due to long-standing thrombosis and compression caused by surrounding hepatic fibrosis with regenerating.
