[Prevention of deep venous thrombosis in hip surgery]

The prophylactic effectiveness of aggregation inhibitors, low heparin dosage, and preoperative normovolaemic haemodilution was studied by the authors in the context of three comparable groups of patients with deep phlebothrombosis. All patients received hip joint substitutes, including artificial heads of the hip in cases of femoral collum fractures or total hip prosthesis in cases of arthrosis deformans. Patients were monitored by fibrinogen tests and ascending phlebography. Results are likely to produce evidence to the effect that haemodilution is an effective method for treatment of deep phlebothrombosis.
