Summary
This study demonstrates that pigs are a viable model for single lung transplantation surgical technique development. The use of a silicon cuff to occlude the pulmonary artery allowed for successful perioperative functional evaluation of the transplanted lung.
Area of Science:
- Veterinary Surgery
- Thoracic Surgery
- Transplantation Research
Context:
- Developing and refining surgical techniques for single lung transplantation is crucial for improving patient outcomes.
- Previous research has utilized canine models, but exploring alternative animal models can offer distinct advantages.
- Standardization of surgical procedures and perioperative evaluation methods is essential for reproducible research in transplantation.
Purpose:
- To establish and validate a surgical technique for single lung transplantation in pigs.
- To develop a method for perioperative functional assessment of an isolated transplanted lung in a porcine model.
- To evaluate the feasibility and advantages of using pigs for single lung transplantation research.
Summary:
- Twenty-two pigs underwent single lung transplantation, with initial experiments focusing on smaller animals (8-12 kg) and subsequent trials using larger animals (>20 kg) to overcome technical challenges.
- A key innovation involved using an inflatable silicon cuff around the right pulmonary artery to achieve complete occlusion, enabling functional evaluation of the isolated transplanted lung.
- Perioperative functional assessments were conducted up to postoperative day three, consistently documenting the good status of the transplanted lung, mirroring successful techniques in canine models.
Impact:
- This research validates pigs as a cost-effective and practical animal model for advancing single lung transplantation surgical techniques.
- The developed methodology for isolating and evaluating lung function post-transplantation provides a robust platform for future preclinical studies.
- The findings support the translation of successful canine transplantation protocols to a porcine model, potentially accelerating innovation in thoracic surgery.
