NCT01221805

Brief Summary

The purpose of this study is to demonstrate the ability of STA® Liatest® D-Di combined with a clinical pretest probability (PTP) to safely exclude pulmonary embolism (PE) or Deep Venous Thrombosis (DVT) in a 3 month follow-up.

Outcome Measures

Primary Outcomes (1)

  • To demonstrate the ability of STA Liatest DDi combined with a clinical pretest probability (PTP) to safely exclude pulmonary embolism or deep venous thrombosis in a 3 month follow-up

    Occurence of pulmonary embolism or deep venous thrombosis during the 3 month follow-up after negative diagnosis (i.e. patients with PTP low/moderate and negative STA Liatest D-Di test)

    at 3 months

Secondary Outcomes (1)

  • 1. To analyse results homogeneity (inter-centers) in the group "positive D-dimer result and negative diagnosis" (descriptive statistics only). 2. To determine prevalence of VTE in PTP high patients based on imaging results

    at 3 months

Sampling MethodNon-Probability Sample
Study Population

The study population will be recruited from prospective, consecutive, ambulatory outpatients (presenting at the emergency unit or outpatient clinic) suspected of having venous thromboembolism

You may qualify if:

  • Patient is \< 80 years old.
  • Patient presenting at least one of these symptoms indicative of proximal DVT or PE:
  • symptoms for proximal DVT: leg pain, tenderness (discomfort through palpation), leg swelling, and /or edema,
  • symptoms for PE: hemoptysis, lung related chest pain, dyspnea.
  • Patient provides written informed consent to participate in the study (or verbal no-opposition, as allowed by local regulations)
  • Patient is willing to comply with specified follow-up evaluation at 3 months and can be contacted by telephone

You may not qualify if:

  • Patient presenting with a condition that may be associated with increased D-dimer levels, even in the absence of VTE, such as:
  • Fibrinolytic therapy within the previous seven (7) days,
  • Bone fracture or surgery (with general anesthesia longer than thirty (30) minutes) within the previous one (1) month,
  • Deep hematoma diagnosed by imaging techniques within the previous one (1) month,
  • Disseminated malignancies and active cancer (active cancer defined as: cancer for which therapeutic or palliative treatment is either ongoing at the time of enrolment or has stopped less than six (6) months before enrolment),
  • Sepsis, severe infections, pneumonia within the previous 1 month,
  • Known liver cirrhosis,
  • Pregnancy or post-partum within the previous 1 month,
  • Atherosclerotic vascular disease thrombosis within the previous 1month (e.g. myocardial infarction, stroke, coronary syndrome, peripheral artery disease stage III or IV),
  • Sickle cell disease,
  • Patients presenting with a suspect thrombotic event related to catheter implantation
  • Ongoing therapeutic anticoagulants (curative and preventive treatment) starting twenty four (24) hours or more before the D-dimer is measured
  • Previous anticoagulant therapy stopped less than three (3) months before the D-dimer is measured
  • Patients with previous DVT/PE occurred less than three (3) months from screening.
  • Suspect thrombotic events in other locations at screening, including distal to the knee and upper extremity DVT (based on standard of care examinations)
  • +3 more criteria
