Consequently, this discrepancy can make the localization of small or subsolid nodules challenging during the operation.

Moreover, the optimal treatment for intermediate-risk patients remains undetermined. With the development of technology, a series of endovascular interventional treatments are widely used in patients with intermediate-high-risk or high-risk PE, such as standard catheter-directed thrombolysis (SCDT), ultrasound-assisted thrombolysis (USAT), pharmacomechanical catheter-directed thrombolysis (PM-CDT) and mechanical thrombectomy (MT). Current studies have shown that interventional therapy can effectively improve right heart function and reduce the incidence of cerebral hemorrhage. Future research should mainly focus on screening patients who benefit from interventional therapy, reducing mortality, and improving long-term sequelae.

This issue significantly hinders the availability of this life-saving procedure for patients in need. To alleviate this shortage, researchers have turned to ex vivo lung perfusion (EVLP) technology as a means to evaluate and potentially repair marginal donor lungs, thereby increasing the donor pool and improving access to transplantation. However, it is important to note that the current capabilities of EVLP technology are still somewhat limited, and further research, development, and optimization are necessary to maximize its potential. To advance this field of study, animal experiments play a crucial role in providing a controlled environment for exploring the possibilities and limitations of EVLP. Among the various animal models available, the small animal EVLP platform for rats stands out by virtue of its simplicity, convenience, and cost-effectiveness. This platform offers researchers a unique opportunity to gain valuable insights into the workings of EVLP and its potential applications in LTx. However, conducting these experiments is not without its challenges. The complexity of the procedure requires a deep understanding of the relevant considerations and operational skills. To ensure the success of these experiments, it is essential that researchers have a comprehensive grasp of the intricacies involved. Drawing upon our practical experience over the past 3 years, our Jiangxi team has systematically refined and summarized the specific details of a rat EVLP experiment in this paper. It encompasses a comprehensive overview of the experimental setup, procedural steps, and potential pitfalls that should be kept in mind.
