What causes caudate lobe hypertrophy?
The reason that only the caudate lobe shows such huge hyperplasia is unclear. However, differences in different hormones, nutritional elements, and hepatotropic factors in the portal blood flow between the caudate lobe and the other segment of the liver may correlate with the hyperplastic change of the caudate.
What is hypertrophy of the caudate?
Hypertrophy of the caudate lobe is seen in a number of conditions, including: cirrhosis: most common. Budd-Chiari syndrome. primary sclerosing cholangitis (end stage) congenital hepatic fibrosis.
What is the function of caudate lobe?
The caudate lobe (segment I) is the autonomous zone of the liver. It receives portal venous, as well as hepatic arterial, blood from both branches of the aforementioned vessels. Additionally, its biliary drainage is by both branches of the hepatic ducts and its venous return goes directly into the inferior vena cava.
What are the processes of caudate lobe of liver?
The papillary process of the caudate lobe, also known as the medial papillary process, represents a division of the inferior caudate lobe of the liver 1. The inferior aspect of the caudate may be divided into medial and lateral processes.
What is a caudate lobe lesion?
Introduction. The caudate lobe of the liver is not an uncommon site of involvement by primary or metastatic liver neoplasms. Traditionally these lesions have been managed by resection of the caudate lobe along with the right or the left lobe. Isolated caudate lobe resection is an alternative to these major resections.
Can caudate lobe of liver be removed?
Caudate lobe resections, although technically challenging, can be successfully performed with minimal blood loss. Surgery offers potential cure in isolated caudate lobe tumors.
How much of the liver can be removed and still regenerate?
What makes resection possible is the liver’s natural ability to regenerate. Surgeons can remove up to 80 percent of the liver and it will grow back in a matter of weeks if the remaining liver is healthy.
What is a liver lobectomy?
Your surgeon might remove a lobe of your liver. This is called a lobectomy or hemi hepatectomy. The liver can grow back and work normally if you don’t have any underlying problems, such as cirrhosis.
What happens if caudate nucleus is damaged?
Early involvement of the caudate nucleus was found to result in worse outcomes over 4 years of follow-up, including cognitive impairment, depression, and movement problems. Lesions in the caudate nucleus can also result in abulia, also known as apathy or lack of will.
