Limb Ischemia after Heart Transplantation: An Unusual Case of Tissue Embolism

摘要

Major complications of heart transplantation include graft rejection, infection, graft arteriosclerosis, malignancy, and drug toxicity. Among these complications, infections and thrombophilic disorders are of particular interest owing to their major contribution to morbidity and mortality among heart transplantation patients. Thrombophilic disorders are caused by imbalance between hypercoagulation and fibrinolytic states. In this report, we describe a 43-year-old man who had unusual complications of heart transplantation. We presume that the unusual postoperative complications of the patient might have been caused by a faulty surgical procedure, improper use of anticoagulant agents, and incomplete prophylaxis for infections. During the postoperative period, the patient suffered arterial obstruction three times, for which he underwent clot removal via embolectomy. In addition to arterial obstruction, the patient had a mobile mass in the left atrium that was removed by open cardiac surgery. The frozen sample of the cardiac mass was positive for Acinetobacter baumannii. After 7 days of observation in the hospital and proper antibiotic regimen, the patient was sent home with no additional complaints and normal physical examination. We conclude that in heart transplantation patients, the precise performance of the surgical procedure, postoperative care, and early removal of the embolus might reduce morbidities and mortality due to thrombophilic disorders.
