Compression treatment in acute symptomatic proximal deep venous thrombosis - Results of a worldwide survey.

The aim of this study was to illustrate how compression is performed worldwide in proximal DVT and if compression management has changed recently. A global online survey, consisting of 36 questions, was used. The survey was solicited from membership lists of Union Internationale de Phlébologie (UIP) membership societies. For differences between the continents in comparison to Western Europe odds ratios and 95% Confidence Intervals (95%CI) where calculated. We received 626 answers from 41 countries. Compression is routinely used in proximal DVT in all regions (82.8%). 81.4% start compression immediately after diagnosis. In the acute phase of DVT reduction of pain and swelling (91.7%) and PTS prevention (66.2%) are the main reasons for compression. 33.2% recently changed their compression management with 43.5% starting compression earlier and 7.0% later. Compression is still used routinely in proximal DVT in addition to anticoagulation. The changes in international guidelines towards the non-routine use of compression in proximal DVT have not caused significant changes in DVT management.
