Pregnant or planning to be pregnant recently
Acute deep vein thrombosis or tumor thrombus involving the study leg
Know history of thrombophilia (e.g. protein C or S deficiency, anti-thrombin III deficiency, etc )
Any concurrent disease, for example, heart failure, might make the patients unsuitable for surgery
