IntroductionVenous thromboembolic disease is a multifactorial, frequently recurrent pathology, whose treatment is based on anticoagulation. As part of the etiological investigation, screening for an inherited thrombophilia is framed by French guidelines published in 2009. The aim of the study is to assess the contribution of inherited thrombophilias testing in common practice.MethodThis is a retrospective single-center observational study. Over a period of a year, all records of patients who were screened for a hereditary thrombophilia were analyzed. The conformity of the indication of hereditary thrombophilia workup in balance with the guidelines, its completeness and therapeutic impact were studied.ResultsOf the 494 records analyzed, 225 were related to venous thromboembolism. Among them, there were 162 pulmonary embolisms or deep vein thrombosis of the lower limbs. In this subgroup, 57 % of records complied with guidelines and 69 % were complete. Thirty-four thrombophilias were highlighted: 4 protein S deficiencies, 1 protein C deficiency, 4 combined deficiencies, 17 factor V Leiden mutations and 8 factor II G20210A mutations. For one patient, hereditary thrombophilia diagnosis had profoundly changed the curative therapeutic approach.ConclusionAdherence to French guidelines remains limited. In clinical practice, diagnosis of hereditary thrombophilia has little impact on the curative therapeutic approach in venous thromboembolic disease.Copyright © 2016 Société Nationale Française de Médecine Interne (SNFMI).
