BACKGROUND AND PURPOSE The optimal duration of venous thromboembolism prophylaxis in acute stroke patients is unknown. This subanalysis of the Extended Prophylaxis for Venous ThromboEmbolism in Acutely Ill Medical Patients With Prolonged Immobilization (EXCLAIM) study investigated extended-duration thromboprophylaxis with enoxaparin, compared with placebo following standard-duration enoxaparin,...

BACKGROUND AND OBJECTIVES Venous thromboembolism is a frequent and serious disorder influenced by numerous factors. As the first step in creating a tool to assess an individual patient's risk of venous thromboembolism, we carried out a literature review in order to quantify risk factors for venous thromboembolism. EVIDENCE AND INFORMATION SOURCES Risk factors were identified as being either p...

Hyperhomocysteinemia is a risk factor of venous thromboembolism. The risk of recurrence in patients with hyperhomocysteinemia is unknown, and the optimal therapy for these patients after acute venous thromboembolism is uncertain. In a multicenter study, 264 patients with an objectively documented single episode of idiopathic venous thromboembolism were prospectively followed after discontinuati...

OBJECTIVE The aim of this study was to quantify the magnitude of risk reduction for venous thromboembolism events associated with an estradiol transdermal system relative to oral estrogen-only hormone therapy agents. METHODS A claims analysis was conducted using the Thomson Reuters MarketScan database from January 2002 to October 2009. Participants 35 years or older who were newly using an es...

BACKGROUND AND OBJECTIVES The rate of post-operative asymptomatic deep-vein thrombosis in Asian patients remains uncertain. The aim of this study was to estimate the rate of venous thromboembolism, including asymptomatic deep-vein thrombosis, undergoing hip or knee surgery and not receiving pharmacological thromboprophylaxis. DESIGN AND METHODS This was a prospective observational study of a ...

During the past decade idiopathic venous thromboembolism has become a separate entity, a chronic illness which has required prolonged anticoagulation and other prevention strategies to avoid recurrences. This article reviews recent developments regarding unprovoked venous thromboembolism and its relation with thrombophilia. In the beginning, the latest definition of idiopathic venous thromboemb...

background: inherited thrombophilic gene polymorphisms have been related to the pathogenesis of venous thromboembolism and its outcomes. considering the scarcity of data on the frequency of the thrombophilic gene polymorphisms in iranian populations, the aim of this study was to assess such polymorphisms in healthy individuals. materials and methods: this cross-sectional study was performed on ...

Diagnostic algorithms for venous thromboembolism exist, but most do not provide detailed guidance as to which patients, if any, may benefit from screening for thrombophilia. This article provides an overview of the optimized diagnosis of venous thromboembolism, with a focus on the appropriate use of thrombophilia screening.

Background: There are extensive studies indicating that deep venous thrombosis and pulmonary embolism contributes to significant morbidity and mortality after acute ischaemic stroke in the West, with established guidelines for prophylaxis. The situation is less clear in Asia. Accordingly, a literature search was performed to review the available evidence. Methods: A search was performed with al...
