Summary
This study introduces a novel double cuff technique for rat liver transplantation, significantly reducing portal vein clamping time. The simplified surgical approach achieved an 83.1% success rate, demonstrating its clinical viability.
Area of Science:
- Surgical innovation in transplantation
- Experimental animal models in surgery
Background:
- Portal vein clamping time is a critical factor in liver transplantation outcomes.
- Existing techniques may involve prolonged clamping, increasing ischemia-related complications.
Purpose of the Study:
- To develop and evaluate a double cuff method for rat liver transplantation.
- To shorten portal vein clamping time by excluding the
- phrenic ring
- during the procedure.
Main Methods:
- A double cuff technique was employed in rat liver transplantation.
- The
- phrenic ring
- was completely excluded from the donor liver.
- End-to-end anastomosis of the suprahepatic inferior vena cava was performed.
Main Results:
- The portal vein clamping time was reduced to an average of 10.6 minutes.
- The overall successful transplantation rate achieved was 83.1%.
Conclusions:
- The developed double cuff method simplifies the surgical procedure for rat liver transplantation.
- This technique effectively shortens critical portal vein clamping time, potentially improving outcomes.
