[Ultrasonographic aspects of liver segmentation]

Area of Science:

• Hepatobiliary Surgery
• Medical Imaging
• Anatomy

Background:

• Advances in hepatobiliary surgery and imaging drive research into liver segmental anatomy.
• Couinaud's classification is standard for identifying liver pathology.
• Ultrasonography is increasingly utilized for detailed liver segment assessment.

Purpose of the Study:

• To describe the clinical features of liver segment identification using ultrasonography.
• To detail the morphological characteristics of liver segments as defined by Couinaud's classification.
• To highlight the role of ultrasonography in preoperative liver assessment.

Main Methods:

• Review of current literature on liver segmentation and ultrasonography.
• Detailed description of ultrasonographic identification of liver segment boundaries.
• Morphological analysis of liver segments via ultrasound imaging.

Main Results:

• Ultrasonography enables clear visualization of anatomical boundaries for all eight liver segments.
• The review provides detailed morphological descriptions of each segment.
• Ultrasonography offers a comprehensive view of liver segment anatomy.

Conclusions:

• Ultrasonography is a valuable, non-invasive tool for examining liver morphology.
• Routine use of Couinaud's liver segmentation with ultrasonography can enhance surgical planning.
• Accurate topographic assessment of hepatic lesions is crucial for successful radical liver surgery.
