Pre-operative therapeutic plasma Exchange and intravenous immune globulin for the treatment of heparin induced thrombocytopenia in a lung transplant recipient

Abstract

Lung transplantation surgery often relies on the use of intraoperative extracorporeal membrane oxygenation (ECMO) and necessitates the need for high dose anticoagulation. Heparin induced thrombocytopenia complicates intraoperative anticoagulation management during lung transplant surgery requiring ECMO. Though other anticoagulants such as argatroban and bivalrudin are utilized for the treatment of Heparin Induced Thrombocytopenia (HIT), the lack of reversal agents makes it difficult to use these agents intraoperatively in cases with high bleeding risk. This is especially true in patients with end stage fibrotic lung disease with calcified mediastinal lymphadenopathy and pulmonary hypertension undergoing lung transplantation. Here we describe a case of HIT in a patient with Sarcoidosis listed for lung transplant who was treated with Therapeutic Plasma Exchange and Intravenous Immune globulin preoperatively and successfully underwent lung transplantation with the use of intraoperative venoarterial ECMO and heparin anticoagulation.
