Abstract

Heparin-induced thrombocytopenia (HIT) is an immune-mediated condition associated with thrombocytopenia and thrombotic complications. The condition is increasingly recognized in hospitalized patients including severely injured trauma patients. Because these patients may eventually be considered for organ donation, management of the HIT screen positive donor has become an important issue in transplant surgery. We describe the recent management of 2 cardiac allograft donors with HIT. At organ recovery, both male adult donors were hemodynamically stable with a normal appearing heart and no evidence of thrombosis. The donor underwent a routine multiple organ allograft recovery with argatroban infused over 15 minutes immediately before aortic cross-clamping after confirming activated clotting time (ACT) of greater than 400 sec. The cardiac allograft was flushed in the donor operating room with a total of 4 liters of cold Celsior solution. These hearts were transplanted in patients with dilated cardiomyopathy and cardiac sarcoidosis by modified bicaval anastomosis technique using heparin for anticoagulation therapy during cardiopulmonary support. Both were bridged with implantable left ventricular assist device (Heart Mate II and Jarvik 2000, respectively). This management strategy resulted in successful multiple organ transplants (Case 1: heart, two single lungs, liver, 2 kidney, case 2: heart, bilateral lung, liver, pancreas, 2 kidneys). Neither of the heart and other recipients demonstrated signs or symptoms of HIT, or neither had any postoperative thrombotic complications.. Based on this experience, a treatment algorithm for managing HIT donors using argatroban is proposed for heart donors as well as other organ donors [ABSTRACT FROM AUTHOR]
