Summary
This study examined 60 livers to understand hepatic artery anatomy for split-liver transplantation. Variations in hepatic artery anatomy are crucial for successfully dividing the liver into right and left lobes for two recipients.
Area of Science:
- Anatomy
- Surgical Techniques
- Transplantation
Context:
- The demand for liver transplants necessitates innovative surgical approaches.
- Split-liver transplantation allows two recipients to benefit from a single donor liver.
- Understanding liver anatomy is critical for successful organ division.
Purpose:
- To investigate the extra-hepatic arterial distribution and anatomy of the liver.
- To analyze anatomical variations relevant to split-liver transplantation.
- To correlate hepatic artery anatomy with the division of the liver into right and left lobes.
Summary:
- Sixty cadaveric livers were dissected to map hepatic artery variations.
- Key measurements included total liver weight and lobe weights (Right: 890.3g, Left: 649.3g).
- Variations in the origin and branching of hepatic arteries were documented, with the right hepatic artery originating from the celiac trunk in 73.3% and the superior mesenteric artery in 25%.
Impact:
- Provides essential anatomical data for surgeons performing split-liver procedures.
- Highlights the importance of pre-operative anatomical assessment for liver transplantation.
- Contributes to optimizing the utilization of donor livers through advanced surgical techniques.
