摘要
Lung transplantation is the treatment of choice for patients with end-stage lung disease.Currently,just under 5000 lung transplants are performed worldwide annually.However,a major scourge leading to 90-d and 1-year mortality remains primary graft dysfunction.It is a spectrum of lung injury ranging from mild to severe depending on the level of hypoxaemia and lung injury post-transplant.This review aims to provide an in-depth analysis of the epidemiology,pathophysiology,risk factors,outcomes,and future frontiers involved in mitigating primary graft dysfunction.The current diagnostic criteria are examined alongside changes from the previous definition.We also highlight the issues surrounding chronic lung allograft dysfunction and identify the novel therapies available for ex-vivo lung perfusion.Although primary graft dysfunction remains a significant contributor to 90-d and 1-year mortality,ongoing research and development abreast with current technological advancements have shed some light on the issue in pursuit of future diagnostic and therapeutic tools.
