Livmorssegment

Livmorssegment, also known as the liver segment, is a subdivision of the liver, a large organ located in the upper right portion of the abdominal cavity. The liver is divided into several segments, each with its own blood supply and drainage. The exact number and size of liver segments can vary, but they are typically numbered from I to VIII.

The liver segments are important for surgical planning and for understanding the extent of liver disease or injury. Each segment has a unique vascular supply, which can be important for surgical procedures such as liver transplantation or partial hepatectomy, where only a portion of the liver is removed.

The liver segments are not visible on routine imaging studies such as ultrasound or CT scans, but they can be identified using specialized imaging techniques such as magnetic resonance imaging (MRI) with contrast or hepatic angiography. These techniques allow surgeons to map out the liver segments and plan surgical procedures more accurately.

In addition to its role in surgical planning, the liver segment is also important for understanding the spread of liver cancer. Cancer that originates in the liver is often classified based on the segment in which it is found, which can help guide treatment decisions.

Overall, the liver segment is a crucial concept in hepatology and liver surgery, providing valuable information for both diagnostic and therapeutic purposes.
