General medicine management of superficial venous thrombosis of the lower limbs: A survey in Saône-et-Loire]

For a long time, superficial venous thrombosis (SVT) of the lower limbs was considered as benign. Due to lack of clear scientific evidence, its treatment was heterogeneous and even potentially deleterious. Since 2010, several major studies have highlighted the seriousness of SVT, and prophylactic doses of fondaparinux have proven their efficacy for this indication. While the French recommendations have not yet taken on board all this data, has practice already changed?To describe in general practice the usual management of suspected SVT.A descriptive cross-sectional study of general practitioners in Saône-et-Loire. Each doctor taking part was asked to note on a paper questionnaire the details of the last patient in whom they suspected SVT. Data collected included: clinical presentation, diagnostic and therapeutic management and follow-up of the patients.Between 01/01/2014 and 31/03/2014, 88 doctors out of 443 contacted (20%) completed the questionnaire. According to the information they provided, 36 physicians (40.9% [95% CI: 30.6-50.2]) searched for an associated pulmonary embolism. Eighty-two physicians (93.2% [95% CI: 87.9-98.4]) prescribed a venous compression ultrasound (CUS) exploration. Twelve etiological assessments were carried out (13.6% [95% CI: 6.5-20.8]) of which 6 (6.8%) appeared to be justified. 64 (72.7%) of the patients were given an anticoagulant therapy (heparin or fondaparinux), including 15 (17%) at a prophylactic dose and 49 (55.7%) at a curative dose. Forty-nine doctors (55.7% [95% CI: 45.3-66.1]) prescribed a CUS follow-up.General practitioners seem to have adapted their diagnostic practices to the data highlighting the potential seriousness of SVT. The treatment they give, however, remains very variable and potentially deleterious, in particular due to a high rate of treatments given at curative doses.
