Venous thromboembolism (VTE) including deep vein thrombosis (DVT) and pulmonary embolism (PE) is commonly encountered in daily clinical practice. After diagnosis, its management frequently carries significant challenges to the clinical practitioner. Treatment of VTE with the inappropriate modality and/or in the inappropriate setting may lead to serious complications and have life-threatening consequences. As a result of an initiative of the Ministry of Health of the Kingdom of Saudi Arabia, an expert panel led by the Saudi Association for Venous Thrombo-Embolism (a subsidiary of the Saudi Thoracic Society) and the Saudi Scientific Hematology Society with the methodological support of the McMaster University Guideline working group, this clinical practice guideline was produced to assist health care providers in VTE management. Two questions were identified and were related to the inpatient versus outpatient treatment of acute DVT, and the early versus standard discharge from hospital for patients with acute PE. The corresponding recommendations were made following the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) approach.
CONTEXTE: Cet article porte sur le traitement de la maladie de TEV.
MÉTHODES: Nous avons généré une forte (Grade 1) et la faiblesse des recommandations (Grade 2) Sur la base (Grade A), (Grade B), et les preuves de haute qualité de qualité moyenne à faible qualité (grade C).
RÉSULTATS: Pour thrombose veineuse profonde aiguë ou d'embolie pulmonaire (EP), nous recommandons un traitement initial de l'anticoagulant par voie parentérale (Grade 1B) ou anticoagulation par rivaroxaban. Nous suggérons héparine de bas poids moléculaire (HBPM) ou le fondaparinux sur IV héparine non fractionnée (Grade 2C) ou sous-cutanée d'héparine non fractionnée (Grade 2B). Nous suggérons un traitement thrombolytique pour PE avec hypotension (Grade 2C). Pour TVP proximale ou une EP, nous recommandons un traitement de 3 mois sur des périodes plus courtes (Grade 1B). Pour une première thrombose veineuse profonde proximale ou EP qui est provoquée par une chirurgie ou par un facteur de risque transitoire non chirurgicale, nous recommandons 3 mois de traitement (1b année; Grade 2B si provoquée par un facteur de risque non chirurgicale et le risque faible ou modéré saignements), qui est sans provocation , nous vous proposons un traitement prolongé si le risque de saignement est faible ou modérée (Grade 2B) et nous recommandons 3 mois de traitement si le risque de saignement est élevé (Grade 1B), et qui est associée à un cancer actif, nous recommandons un traitement prolongé (Grade 1B, 2B grade en cas de risque élevé de saignement) et de proposer des HBPM sur les antagonistes de la vitamine K (Grade 2B). Nous suggérons des antagonistes de la vitamine K ou HBPM sur dabigatran ou rivaroxaban (Grade 2B.) Nous suggérons des bas de contention pour éviter le syndrome post-thrombotique (Grade 2B). Pour une thrombose veineuse superficielle, nous vous suggérons fondaparinux prophylactique à dose unique ou HBPM plus aucune anticoagulation (Grade 2B), et suggérons fondaparinux sur HBPM (Niveau 2C).
CONCLUSION: Des recommandations fortes s'appliquent à la plupart des patients, alors que les recommandations faibles sont sensibles aux différences entre les patients, y compris leurs préférences.
INTRODUCTION: Deep venous thrombosis (DVT) or pulmonary embolism may occur in almost 2 in 1000 people each year, with up to 25% of those having a recurrence. Around 5% to 15% of people with untreated DVT may die from pulmonary embolism. Risk factors for DVT include immobility, surgery (particularly orthopaedic), malignancy, pregnancy, older age, and inherited or acquired prothrombotic clotting disorders.
METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for proximal DVT? What are the effects of treatments for isolated calf DVT? What are the effects of treatments for pulmonary embolism? What are the effects of interventions on oral anticoagulation management in people with thromboembolism? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS: We found 45 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS: In this systematic review we present information relating to the effectiveness and safety of the following interventions: anticoagulation; compression stockings; low molecular weight heparin (short and long term, once or twice daily, and home treatment); oral anticoagulants (short and long term, high intensity, abrupt discontinuation, and computerised decision support); prolonged duration of anticoagulation; thrombolysis; vena cava filters; and warfarin.
