Liver Anatomy Segments
Future liver volume prior to major hepatectomy. Liver volumetry is indicated in patients undergoing major hepatic resection [], defined as resection of four or more segments according to the Couinaud classification [].Most hepatectomies are performed for the treatment of neoplasms, including primary liver cancer (e.g. hepatocellular carcinoma and cholangiocarcinoma), liver metastases (e.g.

A liver segment is one of eight segments of the liver as described in the widely used Couinaud classification (named after Claude Couinaud) in the anatomy of the liver.This system divides the lobes of the liver into eight segments based on a transverse plane through the bifurcation of the main portal vein, arranged in a clockwise manner starting from the caudate lobe.
Couinaud classification of hepatic segments Radiology Reference
PURPOSE: To evaluate qualitatively and quantitatively the current procedures for radiologic delineation of the segmental and subsegmental anatomy of the liver. MATERIALS AND METHODS: Vascular casts of 10 livers were examined with helical computed tomography (CT). Liver segmental and subsegmental anatomy were determined on the CT scans according to customary radiologic practice guidelines. CT.
Couinaud classification of hepatic segments Radiology Reference
Liver segmentation for volumetric assessment is indicated prior to major hepatectomy, portal vein embolisation, associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) and transplant. Segmentation software can be categorised according to amount of user input involved: manual, semi-automated and fully automated.

Couinaud classification of hepatic segments Radiology Reference
They are classically described ('classic lobules') as hexagonal structures made of six vertically aligned portal canals with a central vein. However, microscopic evaluation of the liver usually shows a lack of classic liver lobule as a well-defined connective tissue septum is usually lacking. Liver lobules are enveloped by Glisson's capsule.

The left hepatic artery runs vertically towards the umbilical fissure and supplies segments 1, 2 and 3. It usually gives off a middle hepatic artery branch that runs towards the right side of the umbilical fissure and supplies segments 4a and 4b 2 . Within the liver, the left hepatic artery divides into: medial segmental branch.

Couinaud classification of hepatic segments Radiology Reference
In a portal venous phase CT, the right, middle, and left hepatic veins are usually filled with contrast-mixed blood and can be seen emptying into the inferior vena cava, which is found along the back side of the liver. The portal and hepatic veins divide the liver into segmental anatomy that allows radiologists and surgeons to be very specific.
Diagram and Wiring Diagram Of Liver Segments
sectorial branches will separate each sector of the right liver into two segments (5/8 and 6/7, respectively). In practice, it is convened that all these separations (sectorial and segmental) in the right liver occur at the level of the portal bifurcation. In the left liver, the left portal branch describes an arch towards the round ligament.
Couinaud classification of hepatic segments Radiology Reference
These vessels and segments include the celiac artery, the common and proper hepatic arteries, the left and right hepatic arteries and branches, the caudate lobe, and the portal vein and branches.
Liver Segments Ct Scan
The hepatic segmentation (lobes, parts, divisions and segments) is the oganization of the liver into parts, divisions and segments.

Citation, DOI, disclosures and article data. The AAST (American Association for the Surgery of Trauma) liver injury scale, recently revised in 2018, is the most widely used liver injury grading system 3. The 2018 update incorporates "vascular injury" (i.e. pseudoaneurysm, arteriovenous fistula) into the imaging criteria for visceral injury 3.

The middle hepatic vein separates the right liver from the left liver and the right hepatic vein separates the right posterior sector and anterior sector. The plane of the portal vein is used to divide the different segments into upper and lower sectors (this plane is correct for the segments of the right liver but false for segments II and III.
