肝移植术后手术部位曲霉菌及毛霉菌感染临床分析

Combined Aspergillus and Mucor infections in the surgical site after liver transplantation

目的 探讨原位肝移植术后手术部位曲毛霉菌感染的防治.方法 回顾性分析我院肝胆外科2例感染曲毛霉菌患者的临床资料,对其症状、诊断及治疗进行总结.结果 例1患者术后移植物动脉感染曲霉菌及毛霉菌,导致血管突发破裂出血,终因多器官功能衰竭死亡.另1例患者术后出现手术切口深部毛霉菌感染并合并肺曲霉菌感染,给予强效抗真菌支持治疗后无明显好转,最终死于全身严重感染及呼吸功能衰竭.结论 肝移植术后以手术部位为首发临床表现的曲毛霉菌混合感染临床表现隐匿,病情进展快,预后凶险.

Objective To report the combined Aspergillus and Mucor infections in surgical site after orthotopic liver transplantation. Methods We retrospectively analyzed clinical data of two liver transplantation recipients suffering from postoperative combined Aspergillus and Mucor infections and evaluate the symptoms, diagnosis and treatment. Results In the first patient the graft arteries suddenly ruptured on the 8th day postop caused by Aspergillus and Mucor infection failing an emergency surgical rescue. The patient eventually died of multiple organ failure. In the second recipient deep surgical site infection was diagnosed on the 10th day postop. Combination infection of Aspergillus and Mucor was identified by pathology. Despite of aggressive anti-fungal treatment and support, the general condition continued to deteriorate and the patient eventually died of systemic severe infection and respiratory failure. Conclusion Combined Aspergillus and Mucor infections in operative location is a rare complication of liver transplantation, which was usually occult in onset, and the prognosis is poor.
