Risk Factors of Venous Thrombosis Development at Primary Hip Arthroplasty

Abstract

The purpose of the work was to determine the factors responsible for the development of lower extremity deep vein thrombosis (DVT) after total hip arthroplasty in patients with aseptic femoral head necrosis and coxarthrosis. Complex clinical laboratory examination was performed in 56 patients aged 26 - 85 years (mean 59.11±2.42). At hospitalization stage 11 (19.64%) cases of DVT development were recorded. It was stated that more often thrombosis developed on the background of the lower limb veins pathology (varicose great saphenous vein, changes in deep veins after great saphenous vein thrombophlebitis). In group of patients with DVT statistically significantly more often the inflammatory reaction markers (leukocytosis and ESR), thrombocytosis as well as shortened APTT and increased fibrinogen levels. Besides, for DVT patients the more prolonged surgery, more marked blood loss and more often use of cement were typical. Such peculiarities may play a certain role in the development of thrombohemorragic complications after total hip arthroplasty and should be taken into consideration as a risk factor of venous thrombosis development at this type of surgical intervention.
