Carbapenem-resistant Klebsiella pneumoniae infection causing rupture of graft artery in solid organ recipients

Rationale: Donor-derived bacterial infection is a rare cause of morbidity after solid organ transplantation (SOT) but associated with significant morbidity and mortality, deaths caused by carbapenem-resistant Klebsiella pneumoniae (CRKP) infection account for a considerable proportion of postoperation mortality rate in liver and kidney recipients. The arterial rupture as a result of fungal arteritis is occasionally described, while the rupture of graft vascular anastomosis after SOT due to donor-derived CRKP infection is rarely reported. Patients concerns: We reported 1 patient with donor-derived CRKP infection following liver transplantation and 2 patients following renal transplantation (1 liver and 2 kidneys were from the same donor), who experienced sudden abdominal pain and abdominal hemorrhage almost at the same time after organ transplantation. Diagnosis: The patients were diagnosed as graft arteries rupture due to corrosion caused by CRKP infection based on computed tomography scan, blood culture, laparotomy, and pulse-field gel electrophoresis. Interventions: Anti-shock treatment, exploratory laparotomy, broad-spectrum antibiotics, and abdominal puncture and drainage were given. Outcomes: The liver recipient survived as well as the liver graft, still under treatment of multiple abdominal infections. The 2 renal recipients were alive after resection of the renal grafts and underwent hemodialysis. Lessons: Rupture of graft artery should be foreseen when donor-derived CRKP infection was confirmed and broad-spectrum antibiotics and other interventions need to be considered.
