The purpose of this study is to see if a blood test (D-dimer) is as precise as the CT scan for the detection of clots.
A pulmonary embolism is an obstruction of the blood vessels in your lungs usually due to a blood clot that travels to the lungs usually from the leg. Research has shown that the results of a specific blood test (D-dimer) can be used instead of a CT scan to diagnose clots. D-dimer is a valuable diagnostic marker in either detecting the presence of or monitoring the progress of blood clots. D-dimer assays have proven to be a beneficial diagnostic tool in the evaluation of patients with suspected pulmonary embolism (PE).

To determine whether D-Dimer testing, using the MDA D-Dimer assay, can be used to simplify the diagnostic process for pulmonary embolism (PE). This will be assessed by performing a cohort...
Objective: To evaluate whether trimester specific d-dimer levels and brain natriuretic protein (BNP), along with the modified Wells score (MWS), is a useful risk stratification tool to exc...
The purpose of this study is to determine if the risk of recurrent venous thromboembolism (VTE) after stopping therapy is low and acceptable in patients with a first unprovoked proximal de...
The main objective of the trial is to determine whether D-dimer testing combined with assessment of Pre-Test-Probability (using a standardized clinical model) can be used to markedly simpl...
A multicentre multinational prospective management outcome study has recently proven the safety of a diagnostic strategy combining clinical probability assessment with an age-adjusted D-di...
A low D-dimer can exclude suspected pulmonary embolism (PE) in cases with low or intermediate clinical probability of disease. Yet D-dimer is nonspecific, so many cases without PE require imaging. D-d...
Measurement of a D-dimer level can be a powerful tool in the diagnosis of venous thromboembolism in the right context and with the right application. Used correctly, a clinical strategy combining pret...
We aim to clarify the incidence of deep venous thrombosis (DVT) before treatment in women with ovarian cancer and identify risk factors for DVT.In this prospective study, 110 women underwent venous ul...
To evaluate the value of conventional and age-adjusted D-dimer cut-off value combined with 2-level Wells score for diagnosis of suspected pulmonary embolism.
Gastric cancer metastasis to the lung can rarely manifest as solitary pulmonary nodule. The surgical strategies are different between metastasis from gastric cancer and primary lung cancer; therefore,...
Hypertrophy and dilation of the RIGHT VENTRICLE of the heart that is caused by PULMONARY HYPERTENSION. This condition is often associated with pulmonary parenchymal or vascular diseases, such as CHRONIC OBSTRUCTIVE PULMONARY DISEASE and PULMONARY EMBOLISM.
Excessive accumulation of extravascular fluid in the lung, an indication of a serious underlying disease or disorder. Pulmonary edema prevents efficient PULMONARY GAS EXCHANGE in the PULMONARY ALVEOLI, and can be life-threatening.
Narrowing below the PULMONARY VALVE or well below it in the infundibuluar chamber where the pulmonary artery originates, usually caused by a defective VENTRICULAR SEPTUM or presence of fibrous tissues. It is characterized by restricted blood outflow from the RIGHT VENTRICLE into the PULMONARY ARTERY, exertional fatigue, DYSPNEA, and chest discomfort.
A cancer registry mandated under the National Cancer Act of 1971 to operate and maintain a population-based cancer reporting system, reporting periodically estimates of cancer incidence and mortality in the United States. The Surveillance, Epidemiology, and End Results (SEER) Program is a continuing project of the National Cancer Institute of the National Institutes of Health. Among its goals, in addition to assembling and reporting cancer statistics, are the monitoring of annual cancer incident trends and the promoting of studies designed to identify factors amenable to cancer control interventions. (From National Cancer Institute, NIH Publication No. 91-3074, October 1990)
Backflow of blood from the PULMONARY ARTERY into the RIGHT VENTRICLE due to imperfect closure of the PULMONARY VALVE.
Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
