Thrombophiliascreening in VTE disease?
Thrombophilia screening, timing? Factor V Leiden (APCR), factor II mutation, antibody (APL) titers can be performed at any time PC, PS influenced by: acute phase, pregnancy, estrogen, VKA (2months) AT UFH -> Perform testing 2-4 weeks following period off anticoagulation, no pregnancy, no estrogen
Thrombophilia: pro contra
PRO? From international angiology vol 32 n 2 April 2013
PRO?
CONTRA significant
Thrombophilia screening Age at first episode VTE Unprovoked >< provoked Family history 1st VTE< 40y Estrogen therapy or pregnancy as the only risk factor <60y unprovoked VTE except significant triggering factor Recurrent VTE Recurrent superficial vein thrombosis in the absence varicose veins VTE unusual sites <50y Warfarin induced skin necrosis or neonates purpura fulminans not related to sepsis Asymptomatic (female in childbearing age) with 1st degree proven symptomatic thrombophilia Patients should be advised and followed up by a specialist hematologist From international angiology vol 32 n 2 April 2013
Cancer screening? YES 10% patients unprovoked PE ->cancer, especially 1-2y after PE 854 pts Symptomatic unprovoked proximal DVT or PE Limited cancer screening: Basic blood testing, chest Xray, screening for breast> 50y, cervical 18-70y, prostate cancer >40y (psa) Limited cancer screening+ abdo pelvis CT (virtual colonoscopy gastroscopy included) No clinical benefit with abdo pelvis CT
Echocardiographyend of hospitalization? No recommendation No toxicity and can help to assess indirectly favorable evolution if massive or submassive PE
Clinical question How do youorganizethe followup of VTE disease? 1 GP 1st week and every month 2 Specialist 1st month and every 3 months 3 GP 1st week and every month + specialist 3 months later 4 GP 1st week and every month + specialist 1 month later
Clinical question But no clear recommendations How 3 monthsisthe do youorganizethe minimal followup duration for of VTE VTE disease? (provoked><unprovoked) 1 GP: ensureoac 1st week and adherence, every months clinicalevolution, 2 Specialist 1st month cancer and screening every 3 months 3 GP 1st week and every month + specialist 3 months later 4 GP 1st week and every month + specialist 1 month later
Clinical question How do youorganizethe followup for PE at 3 months? Echocardiography? 1: Yes 2: No
Echocardiography FOLLOW UP: Detection of chronic thromboembolic pulmonary hypertension CTEPH (incidence 0,1-9,1% 2Y post PE) Routine screening CTEPH after PE not systematically recommended but clinical symptoms and signs are non specific or absent in early CTEPH
Clinical question How do youorganizethe followup for PE at 3-6 months? Lung V/P scintigraphy? 1: Yes 2: No
Interest of lung scintigraphy for follow up PE: Resolution perfusion defect 6 months post PE ->depends on initial extension of perfusion defect ->impact to PE recurrence (47 m f up) ->small studies no recommendation
Clinical question How do youorganizethe followup for PE at 3-6 months? CT ANGIOGRAPHY? 1: Yes 2: No
Interest CT pulmonary angiography for follow up PE Thromb Haemost. 2015 Jul;114(1):26-34. doi: 10.1160/TH14-10-0842. Epub 2015 May 28.

Prospective, multi-center cohort study, 157 patients with acute PE diagnosed by CT pulmonary angiography CTPA-imaging after six months of anticoagulant treatment to assess residual thromboembolic obstruction Follow up 2,5y -> complete PE resolution at 6 m: 84% -> VTE recurrence: 10,2% -> residual obstruction not associated with VTE recurrence : HR 0,92 -> no routine use CTPA for PE follow up
Clinical question How do youorganizethe followup for DVT at 3-6 months? LegCUS DOPPLER? 1: Yes 2: No
OR 1,5 for all DVT (significant) but OR 1,2 for unprovoked DVT (ns)
Thromb Haemost. 2014 Jan;111(1):172-9. Prognostic significance of residual venous obstruction in patients with treated unprovoked deep vein thrombosis: a patient-level meta-analysis. Donadini MP 1, Ageno W, Antonucci E, Cosmi B, Kovacs MJ, Le Gal G, Ockelford P, Poli D, Prandoni P, Rodger M, Saccullo G, Siragusa S, Young L, Bonzini M, Caprioli M, Dentali F, Iorio A, Douketis JD. RVO was independently associated with recurrent VTE (HR = 1.32) (1.06-1.65). Associa-on if RVO was detected 3 months a0er DVT (HR = 2.17) (1.11-4.25), but non-significant if detected later, i.e. >6 months (HR = 1.19) ( 0.87-1.61).

Slide 36 2 for Muriel Sprynger; 9/04/2016
Clinical question How do youorganizethe followup for VTE disease at 3 months? Do you use recurrence VTE prediction models and/or bleeding risk model? 1: Yes 2: No
Patients with PE recur more frequently with a PE Mortality of PE 2-3x higher than DVT
Prediction scores for recurrence of VTE
Abnormal Ddimer (1month): +2points Age<50y: +1point Sex, male: +1point Hormone associated VTE: -2 points DASH SCORE 1 LOW RISK: stop anticoagulation? DASH SCORE >1 HIGH RISK: continuation anticoagulation?
HER D OO model for womenunprovokedvte HER under VKA D O O If 2 high risk recurrence for women Male -> high risk
Predictionscores for bleeding, OAC (VKA) in VTE disease
BLEEDING RISK VTE (1st 3month warfarin anticoagulation)
