The purpose of the study was to evaluate efficacy and safety of the new acute treatment of deep venous thrombosis by use of low-molecular-weight heparin compared with standard treatment using unfractionated heparin, especially concerning long-term morbidity.
Deep-venous thrombosis (DVT) remains a common clinical problem (annual incidence 0.10-0.16%) and long-term morbidity as chronic venous insufficience (CVI) in 10-30%.

As to recurrent DVT, initial treatment with Low-Molecular-Weight Heparin ( to-day's terminology Fractionated Heparin (FH)) and Unfractionated Heparin (UFH) has shown equal efficiency, whereas the efficacy concerning long-term morbidity has only more recently been published.

This study was initiated to compare the efficacy of UFH and FH concerning the incidence of CVI after symptomatic DVT at short-term and long-term follow-up.

Estimate

Drug unfractionated heparin

UFH: Continuous i.v. infusion 100 IU/kg/4hrs initially and then adjusted to maintain APTT value 1.5 - 2.5 the pre-treatment value

  • Other names: Heparin SAD 1000 IU/ml

Drug Tinzaparin (Leo)

FH (Tinzaparin): 175 iu/kg s.c. in the abdomen once daily

  • Other names: Innohep (Leo)

1 Active Comparator

UFH: patients treated with unfractionated heparin

2 Experimental

FH: patients treated with low-molecular-weight (fractionated) heparin

Criteria

Inclusion Criteria:

First DVT with or without known risk factors except overt cancer
Second DVT more than two years after the first if the patient was without clinical signs of CVI.

Exclusion Criteria:

Contraindication to anticoagulation therapy
Candidate to thrombectomy with arterious-venous fistula or thrombolytic therapy
Known cancer at the time of the DVT diagnosis
Patients unable to cooperate for anticoagulation therapy or manage the tests.
