title: The prevention of postoperative deep vein thrombosis.
abstract: Numerous recent reports have appeared dealing with the prevention of postoperative deep vein thrombosis. Simple mechanical measures are inadequate, electrical stimulation has complications, but  the motorised foot mover and pneumatic compression appear effective. Drugs such as coumadin, aspirin and dipyridamole are ineffective, but dextran and sodium pentosan polysulphate appear to have a place. However, if the efficacy and safety of low-dose subcutaneous heparin is statistically confirmed in a multicentre trial, it may lead to the elimination of the morbidity and mortality of postoperative thrombo-embolism.
