A straightforward guide to the swine left upper lobar transplant model: procedures and techniques.

Abstract

With the rising demand for lung transplants, especially for adults with smaller chest cavities and children, a significant donor-recipient size mismatch challenge exists. A solution is lobar lung transplants from deceased donors with otherwise unsuitable lungs due to local damage. Despite its promise, early post-transplant mortality rates are comparatively high, emphasizing the need for meticulous donor selection and graft evaluation. This video tutorial introduces a detailed methodology for a porcine left upper lobar lung transplant model, from preoperative measures to reperfusion. Steps encompass preoperative measures, donor and recipient preparations, graft procurement and specific anastomosis procedures for the bronchus, pulmonary artery and left atrium. This guidance, derived from rigorous translational research, not only contributes to the knowledge of safe lobar lung transplants in animals but also promises potential implications for clinical practice.
