Introduction

This review delves into how machine perfusion (MP) is revolutionizing liver transplantation by offering enhanced assessment and viability for donor organs.

Description

Recent extensive reviews summarize the latest breakthroughs in organ preservation, including advanced machine perfusion (MP) techniques and innovative preservation solutions [6]. These advancements encompass advanced machine perfusion (MP) techniques and innovative preservation solutions. The goal is clear: extend donor organ viability, reduce ischemia-reperfusion injury, and enable the use of more marginal grafts, thereby directly addressing the global organ shortage. In liver transplantation, machine perfusion is actively revolutionizing practices by offering enhanced assessment and viability for donor organs. It outlines current MP techniques, emphasizing their role in expanding the donor pool and improving transplant outcomes. The field also anticipates future directions and tackles hurdles in integrating MP into standard clinical practice for liver grafts [1]. Furthermore, a systematic review and meta-analysis examining hypothermic machine perfusion (HMP) in liver transplantation shows that HMP can reduce post-reperfusion syndrome and significantly improve early graft function when compared to static cold storage. This is especially true for grafts obtained from extended criteria donors, solidifying HMP's role as a valuable technique in liver preservation [8].

Focusing on kidney transplantation, a systematic review and meta-analysis extensively evaluates the effectiveness of normothermic machine perfusion (NMP). The compelling findings suggest that NMP can notably enhance graft function and considerably decrease the incidence of delayed graft function, proving particularly beneficial for marginal kidneys. This positions NMP as a promising and superior preservation method [2]. Beyond the preservation method itself, research is investigating the utility of biomarkers identified during kidney machine perfusion for predicting post-transplant graft outcomes. This systematic review highlights the considerable potential for these biomarkers to objectively assess organ quality, to refine current preservation strategies, and ultimately, to improve the selection and utilization of donor kidneys, leading to superior long-term results for recipients [7].

Ex vivo lung perfusion (EVLP) represents a transformative technique for lung transplantation. This method enables the crucial assessment, reconditioning, and even repair of marginal donor lungs prior to transplantation. The paper emphasizes EVLP's critical role in expanding the donor pool and enhancing post-transplant success by actively reducing ischemia-reperfusion injury and boosting overall graft quality [4]. Alongside this, optimizing donor lung management, which includes employing the latest preservation techniques, is vital. This involves thorough donor evaluation and the application of modern preservation methods, such as EVLP, to improve both the quality and utilization of donor lungs, culminating in better outcomes for lung transplant recipients [9]. Moving to cardiac transplantation, current heart preservation techniques are undergoing a deep dive, focusing on innovations in both static cold storage and machine perfusion. This analysis addresses the known limitations of conventional approaches and underscores the significant potential of ex vivo heart perfusion to extend critical preservation windows and improve donor heart utilization, all with the aim of achieving better transplant outcomes [3].

The evolving landscape of pancreas preservation for transplantation is also thoroughly mapped out. This includes reviewing both established static cold storage techniques and innovative machine perfusion methods. The challenges related to pancreatic graft viability are pinpointed, and the article explores how advanced preservation strategies can effectively mitigate ischemia-reperfusion injury, ultimately aiming to improve post-transplant outcomes and significantly broaden the donor pool for pancreas grafts [5]. Moreover, a systematic review and meta-analysis evaluates the impact of normothermic regional perfusion (NRP) in donors after circulatory death (DCD) on transplant outcomes. The compelling findings suggest that NRP can significantly enhance the quality and viability of organs from DCD donors, successfully reducing delayed graft function and expanding the pool of transplantable organs, particularly for kidneys and livers [10].

Conclusion

Organ preservation for transplantation is undergoing a significant transformation, moving beyond traditional static cold storage to embrace advanced machine perfusion (MP) techniques. These innovations are crucial for extending donor organ viability, reducing ischemia-reperfusion injury, and enabling the utilization of more marginal grafts, directly addressing the global organ shortage. For instance, machine perfusion is revolutionizing liver transplantation by enhancing the assessment and viability of donor organs, expanding the donor pool, and improving transplant outcomes, though integration into standard clinical practice presents ongoing hurdles. Similarly, normothermic machine perfusion (NMP) has shown efficacy in kidney transplantation, improving graft function and lowering the incidence of delayed graft function, particularly beneficial for marginal kidneys, positioning NMP as a superior preservation method. New heart preservation techniques, including ex vivo heart perfusion, are extending preservation windows and boosting donor heart utilization for better outcomes. Ex vivo lung perfusion (EVLP) is also proving transformative for assessing, reconditioning, and repairing marginal donor lungs, critically expanding the donor pool and enhancing post-transplant success by mitigating ischemia-reperfusion injury. The evolving landscape of pancreas preservation also highlights the role of advanced strategies in mitigating ischemia-reperfusion injury and broadening the donor pool. Furthermore, identifying biomarkers during kidney machine perfusion offers potential for objective organ quality assessment and refining preservation strategies for superior long-term recipient results. Hypothermic machine perfusion (HMP) in liver transplantation has shown promise in reducing post-reperfusion syndrome and improving early graft function, especially for extended criteria donors. These advancements collectively aim to optimize donor organ management across various organs, leading to improved outcomes for transplant recipients.
