Abstract While the haemorrhagic consequences of anti-coagulants are well and frequently described in the surgical literature the paradoxical prothrombotic tendencies of these drugs tend to be underrecognised due perhaps to their clinical infrequency. However when these effects pertain their consequences can be devastating. Here we present a postoperative oncology patient who suffered a massive recrudescence of his lower limb venous thrombosis immediately after discontinuation of his heparin infusion despite seemingly being adequately anticoagulated by warfarin therapy INR . We intend this case to graphically illustrate the theoretical considerations that must govern the perioperative use of these drugs in high-risk patients. Introduction Despite increasingly effective regimens for its prophylaxis and prevention venous thrombo-embolic disease remains a common and serious cause of both morbidity and mortality in surgical patients. 1 As predisposing and precipitating factors .
