Thrombosis is clearly a common cause of death in the US. It is obviously of major importance to define the aetiology of deep vein thrombosis (DVT) as (i) many of these events are preventable if appropriate therapy, dependent upon the risk factors known is utilised; (ii) appropriate antithrombotic therapy will decrease risks of recurrence; (iii) the type of defect(s) and risk(s) will determine length of time the patient should remain on therapy for secondary prevention and (iv) if the defect is hereditary appropriate family members can be assessed. Aside from mortality, significant additional morbidity occurs from DVT including, but not limited to, stasis ulcers and other sequelae of post-phlebitic syndrome. ⋯ However, if the ongoing risk of DVT remains high or if a history of recurrent DVT dictates, lifelong therapy might be indicated. The recommendations presented are based upon published controlled trials; however, indications for therapy and therapeutic agents of choice will continually evolve. By applying the principles outlined in this review, substantial cost savings, reduction in morbidity and reductions in mortality should occur.
