The caudate process is a small elevation of the hepatic substance extending obliquely and laterally, from the lower extremity of the caudate lobe to the undersurface of the right lobe. The caudate lobe has a complex blood supply system. It derives its arterial supply from the caudate arteries, which arise from the right, left, and middle ...
Caudate lobe hypertrophy on ultrasound due to cirrhosis Hepatofugal (non-forward) flow in portal vein. The diagnosis of cirrhosis in an individual is based on multiple factors. [33] Cirrhosis may be suspected from laboratory findings, physical exam, and the person's medical history. Imaging is generally obtained to evaluate the liver. [33]
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 signs of liver failure. [5]
Hepatomegaly is enlargement of the liver. [4] It is a non-specific medical sign, having many causes, which can broadly be broken down into infection, hepatic tumours, and metabolic disorder. Often, hepatomegaly presents as an abdominal mass. Depending on the cause, it may sometimes present along with jaundice. [1]
The liver is grossly divided into two parts when viewed from above – a right and a left lobe – and four parts when viewed from below (left, right, caudate, and quadrate lobes). [16] The falciform ligament makes a superficial division of the liver into a left and right lobe. From below, the two additional lobes are located between the right ...
Axial and coronal images in the portal venous phase. Increased pressure in the sublobular branches of the hepatic veins causes an engorgement of venous blood, and is most frequently due to chronic cardiac lesions , especially those affecting the right heart (e.g., right-sided heart failure ), the blood being dammed back in the inferior vena ...
The right hepatic vein is the longest and largest of all the hepatic veins. It drains the liver segments VI and VII in their entirety, and variably participates in the drainage of segments V and VIII; the extent of drainage of the latter two segments by the right hepatic veins as opposed to the middle hepatic vein and possible variant accessory veins determines the calibre of the right hepatic ...
Portal hypertensive gastropathy refers to changes in the mucosa of the stomach in patients with portal hypertension; by far the most common cause of this is cirrhosis of the liver. These changes in the mucosa include friability of the mucosa and the presence of ectatic blood vessels at the surface.
