Introduction
Renal allograft thrombosis is responsible for approximately 27% of early allograft loss [13]. Data from the Australian and New Zealand Dialysis and Transplant Registry demonstrate a constant rate of grafts lost due to thrombosis over the last 10 years [4]. Graft thrombosis is characterized by sudden anuria and almost inevitable irreversible loss of function. Venous thrombosis is more common, usually occurs within the first 2 weeks, and is accompanied by graft pain and swelling, frequently with allograft rupture. Arterial thrombosis may be painless and without swelling or rupture; however, thrombosis of both arterial and venous conduits can occur, and distinguishing the site of origin of thrombus may be impossible. Until recently, mechanisms for this catastrophic event were considered to reflect general and non-specific perturbations of coagulation associated with or exacerbated by the dialysis or surgical procedure, immunosuppressive drugs, technical errors, donor vessel abnormalities, vascular
