To refine 1974 results on venous thrombosis and oral contraceptives (OCs) from a prospective study begun in 1968 comparing 23,000 women using OCs with 23,000 controls, women with known preexisting conditions relevant to thrombosis were excluded. Rates in each contraceptive category (users, ex-users, and controls) were indirectly standardized for age, parity, cigarette consumption, and social c...

Pulmonary embolism is a serious, life-threatening condition and most commonly derives from deep vein thrombosis of the lower extremities. Once deep vein thrombosis (DVT) reaches a proximal vein (i.e., popliteal vein or higher), pulmonary embolism reportedly occurs in up to 50% of patients. Case Presentation. We report on an inpatient with major depressive disorder in a catatonic state in whom a...

BACKGROUND Several diagnostic strategies using ultrasound imaging, measurement of D-dimer, and assessment of clinical probability of disease have proved safe in patients with suspected deep-vein thrombosis, but they have not been compared in randomized trials. METHODS Outpatients presenting with suspected lower-extremity deep-vein thrombosis were potentially eligible. Using a clinical model, ...

Background: Venous thromboembolism (VTE) is a significant complication in cancer patients which was found in 4-20% of the patients. This study was aimed to evaluate risk factors of deep vein thrombosis (DVT) in cancer patients in an oncology center in Indonesia.  Methods: This was a retrospective cohort study. Data were obtained from medical records of adult cancer patients with DVT referring ...

BACKGROUND There are limited reports of thrombosis among myelodysplastic syndrome patients exposed to erythropoiesis stimulating agents. It is not clear whether erythropoiesis stimulating agents are associated with an increased risk of thrombosis in myelodysplastic syndromes, as they are among patients with solid tumors. DESIGN AND METHODS The association between use of erythropoiesis stimula...

PURPOSE The purpose of this study was to identify the features, risk scores and risk factors for deep vein thrombosis in critically ill patients who developed deep vein thrombosis in their lower extremities. METHODS The participants in this prospective descriptive study were 175 adult patients who did not receive any prophylactic medication or mechanical therapy during their admission in the ...

OBJECTIVE To identify factors that predict a positive duplex scan examination result in patients with suspected deep vein thrombosis of the lower extremity. DESIGN Retrospective study. SETTING Vascular laboratory in a university teaching hospital. PATIENTS AND METHODS The results of 345 lower extremity duplex venous scans performed between August 1994 and November 1998 were reviewed. All ...

OBJECTIVE Post-thrombotic syndrome causes considerable morbidity. The Home-LITE study showed a lower incidence of post-thrombotic syndrome and venous ulcers after 3 months of treating deep vein thrombosis with the low-molecular-weight heparin tinzaparin versus oral anticoagulation. This systematic review examined whether long-term treatment of deep vein thrombosis using low-molecular-weight hep...
