Auscultation shows slight decreased mumure in the right base of the thorax, no rales, no crackles. Auscultation shows slight decreased mumure in the right base of the thorax, no rales, no crackles.

13 DVT & Pulmonary Embolism 117 cases / 100.000 persons in USA (increases with the age) 117 cases / 100.000 persons in USA (increases with the age) Importance of risk factors (immobilization, contraceptive drugs, flight travel, familial or personal past history) Importance of risk factors (immobilization, contraceptive drugs, flight travel, familial or personal past history) Most clinical PE originate from a proximal DVT from the legs above the knee (popliteal, femoral or iliac vein) Most clinical PE originate from a proximal DVT from the legs above the knee (popliteal, femoral or iliac vein) As many patients have intermediate probability of venous thrombosis, clinical jugement is still the cornerstone of the diagnosis. As many patients have intermediate probability of venous thrombosis, clinical jugement is still the cornerstone of the diagnosis.

14 Risk factors

15 D-Dimer tests D-Dimer are very sensitive but have a very low specificity (Good negative predictive value) D-Dimer are very sensitive but have a very low specificity (Good negative predictive value) D-Dimer can rule out the diagnosis of PE in only 5% of patients aged > 80 years (60% in young patients 80 years (60% in young patients < 40 years old) Low risk of DVT assessment by validated prediction score and a negative D-dimer test (Latex agglutination) is deemed to rule out the diagnosis of DVT. Low risk of DVT assessment by validated prediction score and a negative D-dimer test (Latex agglutination) is deemed to rule out the diagnosis of DVT. D-Dimer positive result does not raise the likelihood of DVT and has therefore limited clinical value alone. D-Dimer positive result does not raise the likelihood of DVT and has therefore limited clinical value alone.

16 Clinical probability score (Geneve Score)

17 Wells score of probability for PE

18 Assess clinical probability

19 Use of d-dimer and angio-CT for the diagnosis of Pulmonary Embolism

20 Decisional algorithm for the diagnosis of PE

23 Principle of PE treatment Immediate full anticoagulation is mandatory for all patients suspected of having have DVT or pulmonary embolism. Immediate full anticoagulation is mandatory for all patients suspected of having have DVT or pulmonary embolism. Diagnostic investigations should not delay empirical anticoagulant therapy. Diagnostic investigations should not delay empirical anticoagulant therapy. Current guidelines recommend starting unfractionated heparin (UFH), low–molecular weight heparin (LMWH), or fondaparinux (all grade 1A) in addition to an oral anticoagulant (warfarin) at the time of diagnosis Current guidelines recommend starting unfractionated heparin (UFH), low–molecular weight heparin (LMWH), or fondaparinux (all grade 1A) in addition to an oral anticoagulant (warfarin) at the time of diagnosis Discontinue UFH, LMWH only after the international normalized ratio (INR) is 2.0 for at least 24 hours, but no sooner than 5 days after warfarin therapy has been started (grade 1C recommendation). Discontinue UFH, LMWH only after the international normalized ratio (INR) is 2.0 for at least 24 hours, but no sooner than 5 days after warfarin therapy has been started (grade 1C recommendation).

24 Curative Treatment Low molecular weight heparin (LMWH) Low molecular weight heparin (LMWH) LOVENOX 0.1ml/10Kg sub-cut twice a day LOVENOX 0.1ml/10Kg sub-cut twice a day Early relay with anti-vitamin K by mouth Early relay with anti-vitamin K by mouth INR after 48-72h of treatment INR after 48-72h of treatment Stop Heparin when INR 2< <4 at 2 times Stop Heparin when INR 2< <4 at 2 times Duration of efficient anticoagulation minimum 3 to 6 months (according persistent risk factors) Duration of efficient anticoagulation minimum 3 to 6 months (according persistent risk factors)
