Dysfunction of oxidative phosphorylation and the mitochondrial respiratory chain leads to a heterogeneous group of pathogenic mitochondrial variations. The TRMU gene codes for transfer RNA 5- methylaminomethyl-2-thiouridylate methyltransferase and is essential for posttranscriptional modification of the mitochondrial transfer RNA, and alterations in the TRMU gene can lead to infantile liver failure at approximately 6 months of age. Orthotopic liver transplant is a curative option. We present a case of a patient with TRMU alteration who underwent liver transplant at 11 months of age to treat infantile end- stage liver disease. The patient had liver failure due to long-standing allograft rejection and required another liver transplant at age 24 years, and here we discuss the perioperative care of this patient. Coordination of the care team to prevent rhabdomyolysis or alternative negative catabolic effects was the cornerstone of management in addition to evaluation of unusual electrocardiographic findings in the immediate postoperative period. Although the patient's postoperative course was complicated by repair of a bile leak, liver retransplant successfully restored the patient's preoperative quality of life.
氧化磷酸化和线粒体呼吸链功能障碍导致一组异质性的致病性线粒体变异。TRMU 基因编码转移 RNA 5-甲基氨甲酰基-2-硫代尿嘧啶甲基转移酶,对于线粒体转移 RNA 的转录后修饰至关重要,TRMU 基因的改变可导致约 6 月龄婴儿发生肝衰竭。原位肝移植是一种有治愈希望的选择。我们报告了一例 TRMU 改变的患者,该患者在 11 个月大时接受肝移植以治疗婴儿终末期肝病。该患者因长期同种异体移植物排斥反应导致肝功能衰竭,在 24 岁时需要再次进行肝移植,在此我们讨论了该患者的围手术期护理。协调护理团队以预防横纹肌溶解或其他负面分解代谢作用是管理的基石,此外还需要评估术后即刻不常见的心电图发现。尽管患者的术后病程因胆漏修复而复杂化,但肝再移植成功恢复了患者术前的生活质量。
