[Efficacy and tolerance of low molecular weight heparin in the prevention of deep venous thrombosis during non-emergent total hip arthroplasty. A prospective, multicenter trial].

A multicenter prospective trial was conducted on 149 patients to test the efficacy and tolerance of low molecular weight heparin (LMWH) in the preventive treatment of deep venous thrombosis consecutive to total hip arthroplastic surgery. An original dose-adjusted protocol was tested, whereby the patients were injected a single dose of LMWH daily, determined on a weight and operation date basis; the prophylactic efficacy of this protocol was assessed by bilateral phlebography performed systematically on the 10th postoperative day. Only 12.9% of patients developed deep venous thrombosis of the lower extremities, and the thrombus formation site was proximal in 3.6% of cases. These rates are low compared with published data and considering the diagnostic criterion used. The low incidence of premature treatment withdrawal and hemorrhagic complication (2%) cases is indicative of the good tolerance of this preventive treatment.
