Summary
A new topographical liver nomenclature, based on anatomical position, is proposed. This system aids in precise localization of liver lesions and guides surgical resections.
Area of Science:
- Hepatobiliary anatomy
- Surgical anatomy
- Radiological anatomy
Context:
- Accurate liver anatomy knowledge is crucial for lesion localization and segmental resection.
- Couinaud's segmental classification (I-VIII) is widely used but lacks topographical context.
- Existing nomenclature does not fully account for the liver's position within the abdominal cavity.
Purpose:
- To introduce a topographical liver nomenclature that incorporates anatomical position.
- To provide a practical classification system for surgeons and radiologists.
- To offer a compromise between Anglo-Saxon and Couinaud's classifications.
Summary:
- A topographical nomenclature is proposed, utilizing columns (right posterior, right lateral, right paramedian, left lobe, dorsal) based on J. Hureau's classification.
- This system correlates with Couinaud's segments but emphasizes the liver's spatial orientation.
- It highlights the posterior aspect of the right lateral sector, the lateral position of the right paramedian sector, and the anterior position of the left lobe sectors.
Impact:
- Facilitates more precise localization of liver lesions.
- Improves guidance for segmental liver resections.
- Enhances understanding of liver sectorial anatomy in relation to abdominal topography.
