OBJECTIVE:The purpose of this study was to evaluate the long term clinical and ultrasonographic outcomes of thrombophilic patients with deep venous thrombosis (DVT).METHOD:Cohort study, retrospective case-control with cross-sectional analysis. Thirty-nine thrombophilic patients and 25 non-thrombophilic patients were assessed 76.3 ± 45.8 months after diagnosis. Demographic and family data were collected, as well as data from clinical and therapeutic progress, and physical and ultrasound examinations of the limbs were performed. Groups were matched for age and gender and the variables studied were compared across groups.RESULTS:Deep venous thrombosis was more frequent in women. The most common thrombophilias were antiphospholipid syndrome and factor V Leiden mutation. There was no difference between groups in terms of the number of pregnancies or miscarriages and the majority of women did not become pregnant after DVT. Non-spontaneous DVT prevailed. Proximal DVT and DVT of the left lower limb were more frequent, and the main risk factor was use of oral contraceptives. All patients were treated with anticoagulation. There was a higher frequency of pulmonary embolism in non-thrombophilic patients. Most patients considered themselves to have a normal life after DVT and reported wearing elastic stockings over at least 2 years. Seventy-one percent of patients had CEAP > 3, with no difference between groups. Deep venous reflux was more frequent in thrombophilic patients.CONCLUSION:There were no significant differences between groups with respect to most of the variables studied, except for a higher frequency of pulmonary embolism in non-thrombophilic patients and greater frequency of deep venous reflux in thrombophilic patients.
