BACKGROUND Lung transplantation remains the gold standard treatment for patients with end-stage lung disease. Lobar lung transplantation allows for transplantation of size-mismatch donor lungs in small recipients; however, donor lung volume reduction represents a challenging surgical technique. In this paper we present our initial experience with bilateral lobectomy in donor lungs before lobar lung transplantation using normothermic perfusion on the Organ Care System (OCS) Lung. MATERIAL AND METHODS Specifics of the surgical technique for donor lung instrumentation on the OCS, lobar dissection on the OCS, and right and left donor lobectomies are presented in detail. RESULTS Potential advantages of the use of the OCS for lobectomy for lobar lung transplantation are described in this section. Donor lung volume reduction utilizing OCS appeared to be easier and safer compared to the conventional cold storage technique, due to continuous perfusion of the lungs with blood and well-distended vessels that offer the feel of live lobectomy. Moreover, the OCS represents a platform for donor organ assessment and optimization of its function before transplantation. CONCLUSIONS Donor lung volume reduction was safe and feasible utilizing the OCS, which could be a useful tool for volume reduction in cases of size mismatch. Further research is needed to evaluate early and long-term results after lobar lung transplantation using the OCS in clinical studies.
背景 肺移植仍然是终末期肺病患者的金标准治疗方法。肺叶移植能够在体型较小的受者中移植尺寸不匹配的供体肺;然而,供体肺减容是一项具有挑战性的外科技术。在本文中,我们介绍了我们在器官护理系统(OCS)肺上使用常温灌注进行肺叶移植前对供体肺进行双侧肺叶切除术的初步经验。
材料与方法 详细介绍了OCS上供体肺器械操作、OCS上肺叶解剖以及左右供体肺叶切除术的手术技术细节。
结果 本节描述了在肺叶移植中使用OCS进行肺叶切除术的潜在优势。与传统的冷藏技术相比,利用OCS进行供体肺减容似乎更容易且更安全,这是因为肺持续接受血液灌注且血管充分扩张,给人一种活体肺叶切除术的感觉。此外,OCS是供体器官评估以及移植前功能优化的一个平台。
结论 利用OCS进行供体肺减容是安全可行的,在尺寸不匹配的情况下它可能是一种有用的减容工具。需要进一步研究以评估在临床研究中使用OCS进行肺叶移植后的早期和长期结果。
