    Abstract:
    AIM: To compare effects of prolongation of the treatment with therapeutic doses of enoxaparin to 1 month on recanalization of occlusively thrombosed deep veins (OTDV) of the limbs with results of standard therapy with unfractionated heparin (UFH). Both treatments were followed by warfarin administration. MATERIAL AND METHODS: Thirty patients were selected from 111 patients with a history of deep vein thrombosis (DVT) and/or pulmonary artery embolism according to the following criteria: the presence of occlusive thrombosis of one deep vein minimum; the absence of DVT for 12 months of follow-up. Patients of group 1 (n = 15) received standard therapy (UFH for at least 5 days) with switch to warfarin. Patients of group 2 (n = 15) received therapeutic doses of enoxaparin (1 mg/kg each 12 hours) for 30 days minimum with switch to warfarin. Follow-up was 12 months. Ultrasonic duplex angioscanning of the limbs was made at baseline, 1, 3, 6 and 12 months after treatment start. RESULTS: After follow-up month 1, 3 and 6 number of patients with occlusive DVT was significantly less in group 2. All the patients given enoxaparin achieved recanalization of OTDV within 3 months of treatment. OTDV recanalization was not achieved in 20% patients of group 1 even 12 months after treatment start. CONCLUSION: Prolongation of enoxaparin treatment to 1 month followed by warfarin treatment is superior to standard UFH treatment followed by warfarin in providing recanalization of OTDV within 3 months of treatment. Moreover, this treatment predicts persistence of recanalization within 12 months of anticoagulant therapy.
