The aim of this review is to try to explain the controversy by critical analysis of previously published randomized controlled trials on the value of elastic compression stockings in the treatment of acute proximal deep vein thrombosis in prevention of post-thrombotic syndrome, which forms the scientific basis for our present management. ⋯ Prescription of elastic compression stockings for the prevention of post-thrombotic syndrome is now in doubt. Immediate compression after diagnosis of acute deep vein thrombosis to prevent swelling and reduce pain, permitting early ambulation in combination with adequate anticoagulation has proven benefit, although a secondary analysis of the SOX trial refutes this belief. Continued long-term compression treatment is questioned. Two major questions remain:Is the lack of positive outcome on the development of post-thrombotic syndrome after proximal deep vein thrombosis due to the fact that there were a few patients with iliofemoral extension in the quoted randomized controlled trials who may benefit from prolonged medical compression treatment?Compliance is the major issue, and the two randomized controlled trials with excellent control of compliance showed significant reduction in the rate of post-thrombotic syndrome, but we know that in daily practice the adherence is closer to Kahn's data.
