Understanding Couinaud Classification of Liver Segments

Gastroenterology & Endoscopy

The Couinaud classification is a vital tool in the field of hepatic surgery and diagnoses. It offers a comprehensive understanding of the functional anatomy of the liver by dividing it into eight independent segments. Unlike other classification systems, Couinaud classification focuses on the liver's functional aspects rather than its external appearance.

Key Takeaways:

• The Couinaud classification divides the liver into eight independent functional units called segments.
• The classification aids in precise surgical resections and accurate diagnoses.
• Each liver segment has its own dual vascular inflow, biliary drainage, and lymphatic drainage.
• The Couinaud classification is widely accepted and used in clinical practice.
• It is important for healthcare professionals involved in hepatic surgery, diagnoses, and radiology to understand and apply the Couinaud classification.

Couinaud's innovative approach to liver segmentation has become a cornerstone in modern hepatic surgery, guiding surgeons in planning and executing procedures with utmost accuracy. By preserving the functional integrity of individual liver segments, surgical resection can be performed with optimal outcomes, enhancing patient recovery and long-term prognosis.
