2024年12月28日 · Surgical relevance. The division of the liver into self-contained units allows the surgical resection of individual segments and sections without damaging the remaining segments. Hence, for the liver to remain viable, resections occur along the hepatic veins and portal veins in the planes that define the boundaries of these segments.

2006年5月7日 · The Couinaud classification of liver anatomy divides the liver into eight functionally indepedent segments. Each segment has its own vascular inflow, outflow and biliary drainage. In the centre of each segment there is a branch of …

This resection removes segments VI and VII of the liver, and the principle transection plane is the right portal scissura along the right hepatic vein. The right liver should be mobilized as is done for a right hepatectomy.

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 , [ 1 ] arranged in a clockwise manner ...

2016年6月4日 · Goldsmith and Woodburne 4 divided the liver into the caudate lobe and four distinct segments: Left lateral (Couinaud segments 2 and 3) Left medial (Couinaud segment 4) Right anterior (Couinaud segments 5 and 8) Right posterior (Couinaud segments 6 and 7)

2017年11月6日 · In fact, segments 6 and 7 are posterior to segments 5 and 8, as illustrated by (b), a much more faithful reproduction of the radiological and surgical reality. In this representation, the right and the left liver are defined by the bifurcation of the main portal vein.

2024年2月22日 · The Couinaud classification allows for targeted surgical resections wherein a specific segment or segments can be removed without affecting the functionality of the remaining liver. This precision is crucial to minimize post-surgical complications and …
