The term venous thromboembolism refers to a spectrum of disease that includes deep venous thrombosis and pulmonary embolism. Both deep venous thrombosis and pulmonary embolism are often clinically silent and thus difficult to diagnose, which leads to a substantial delay in treatment that results in high rates of morbidity and mortality. The purposes of this article are to help physicians determ...

Objectives: Venous thromboembolis is a clinical condition that often occurs from deep vein thrombosis of lower extremity. The incidence of deep venous thrombosis in the etiology of pulmonary thromboembolism may be as high as 90%. Doppler ultrasonography of lower extremities is recommended generally to determinate the etiology of pulmonary thromboembolism. The aim of this study is to present the...

the objective of this study was to determine the prevalence and incidence of venous thromboembolism among critically ill medical surgical patients. in this cross sectional and retrospective study, we observed 243 patients who were first admitted at the intensive care unit. patients who were diagnosed with deep venous thrombosis or embolism either by clinical or paraclinical methods were enrolle...

Venous thromboembolism refers to thrombotic events in the venous system that are most commonly manifested as deep vein thromboses in the upper or lower extremity and/or pulmonary embolism. Venous thromboembolism is a common disorder that is associated with significant mortality, morbidity and health care-related cost. An array of hereditary and acquired risk factors are associated with venous t...

OBJECTIVE To estimate the incidence and determine the characteristic features of venous thromboembolism in the Hong Kong Chinese population. DESIGN Retrospective study. SETTING Regional hospital, Hong Kong. SUBJECTS AND METHODS Data were collected during a period of four years (1997-2000). Patients with duplex doppler ultrasonography or venography-documented venous thromboembolism and new...

Venous thromboembolism in pregnancy is a clinical emergency that has been associated with significant risk for maternal and fetal morbidity and mortality. The adaptation of the maternal hemostatic system to pregnancy predisposes women to an increased risk of thromboembolism. A timely diagnosis of deep venous thrombosis is crucial because up to 24% of patients with untreated deep venous thrombos...

international travel has become increasingly common and accessible, hence, about two billion passengers undertake international and domestic air travel each year. venous thromboembolism (vte) is a serious public health disorder which may occur following prolonged travel, especially after air travel. a direct relation between vte development and prolonged travels has been documented, while some ...

AIM The Authors describe diagnosis, treatment and therapy of deep venous thrombosis in Emergency Department following the last guidelines indications. DISCUSSION Deep venous thrombosis of the legs, ranges from asymptomatic, incidentally discovered emboli to massive embolism causing immediate death. Chronic sequelae of venous thromboembolism (deep venous thrombosis and pulmonary embolism) incl...

The authors evaluated the risk of venous thromboembolism associated with hormone replacement therapy in a cohort of 265,431 women aged 45-79 years who did not have major risk factors for venous thromboembolism. Through review of hospital charts, 171 cases were confirmed (pulmonary embolism = 77; deep venous thrombosis = 94). Ten thousand controls were randomly sampled. The risk of venous thromb...

STUDY OBJECTIVE Prediction rules for pulmonary embolism use variables explicitly shown to estimate the probability of pulmonary embolism. However, clinicians often use variables that have not been similarly validated, yet are implicitly believed to modify probability of pulmonary embolism. The objective of this study is to measure the predictive value of 13 implicit variables. METHODS Patient...
