简介：
Overview
This protocol describes a model of porcine orthotopic liver transplantation that does not utilize a veno-venous bypass during engraftment. The technique simplifies the surgical process and minimizes the anhepatic phase while managing volume and vasopressor requirements.
Key Study Components
Area of Science

What is the significance of using a porcine model?
Porcine models closely mimic human physiology, making them ideal for studying liver transplantation.
How does this technique improve surgical outcomes?
By minimizing the anhepatic phase and simplifying the procedure, it reduces complications and enhances recovery.
What are the implications of static cold storage for donor organs?
Static cold storage allows for extended preservation of donor organs, simulating conditions often encountered in clinical settings.
What challenges does this protocol address?
It addresses the logistical and technical complexities of traditional liver transplantation techniques.
Are there any specific preparations needed for the donor pig?
Yes, the donor pig must be anesthetized, positioned, and prepared with antiseptics before surgery.
What future research directions does this study suggest?
Future research may focus on validating the model and exploring its applications in clinical practice.
