Abstract Number: PB2449
Meeting: ISTH 2020 Congress
Background: Venous thromboembolic disease (VTED) is a common and multifactorial disease. The determination of the optimal duration of anticoagulation is a challenge for clinicians.
Aims: The aim of this study was to assess the prevalence of recanalization in control imaging of patients followed for VTE at the end of treatment with vitamin K antagonists (VKA).
Methods: A prospective, longitudinal and descriptive study involving patients with VTE treated by VKA was conducted in an internal medicine department between January 2015 and December 2017. Control imaging was performed for each patient at the end of the agreed period of anticoagulation. The studied population was subsequently divided into two groups according to the absence or presence of venous recanalization in the control imaging in order to investigate its influencing factors.
Results: Sixty patients were included whose average age was 56 years. Twenty-nine patients were male. Eighty percent (n=53) of patients lived in urban areas and 12% (n=7) lived in rural areas. Fifty (83%) patients had deep vein thrombosis, 9 (15%) had pulmonary embolism, and one had superficial thrombophlebitis. Twenty one (35%) were smokers and 19 (32%) were obese. Two patients had a family history of VTED and 3 had a personal history of VTED. 17% of patients had varicose veins in the lower limbs. Hypothyroidism was noted in 4 (7%) patients and active cancer in 2 (3%) patients. 22% (n=13) of patients had recent surgery and 3 (5%) patients had an orthopedic cast. At the control imaging, 65% (n=39) of the patients had totally recanalized and 33% (n=20) had partially recanalized. A complete absence of recanalization was noted in one case. Only the urban / rural living environment had a statistically significant effect on venous recanalization.
Conclusions: Control imaging is not common during therapeutic follow-up of VTE cases. However, it may help to optimize the duration of anticoagulation.
