Endovascular Aortic Crossclamp: A Novel Way to Reduce Warm Ischemia Time in DCD Donors
Strategies like donation after cardiac death (DCD) have become more widely accepted to increase potential organ supply and decrease waiting list time. Warm ischemia time (WIT) is a key prognostic factor for organ function. Any process that can decrease WIT could decrease the number of discarded organs as well as improve graft and patient survival. A novel endovascular aortic crossclamping technique in DCD donors is described. Six kidneys and two livers were recovered from three donors. Mean WIT from extubation to aortic crossclamp was 25 ± 8 minutes. Time from initial glidewire placement to crossclamp was less than 2 minutes. All the organs were adequately flushed; back table examination confirmed clean venous effluent and no signs of thrombosis. Four kidneys were transplanted. Two kidneys were discarded after DCD was prolonged and WIT was 60 minutes. The two livers were not allocated. The WIT can be manipulated after cardiac activity has stopped. The endovascular crossclamp is a novel and feasible technique that can decrease WIT after cardiac death by reducing the surgical time to aortic crossclamp.
