Abstract:
[Objective] To analyze the clinical risk factors for the deep vein thrombosis(DVT)after the total hip arthoplasty(THA).[Methods]Fifty-one THA in 48 patients from February 2007 to July 2007 were evaluated.Color Doppler ultrasonography was used to detect DVT of bilateral lower extremities in all patients before operatioon and at 7 days after operation.Fifteen clinical factors were examined perioperatively in order to analyze their influences on DVT formation after surgery.[Results]Seventeen patients with DVT after operation were discovered through Color Doppler ultrasonic detection,and all of the DVT occurred at the calf intermuscular vein.The incidence of the DVT in all patients was 33.3%,and 41.7% of these DVT patients were asymptomatic.Logistic regression analysis indicated that patients older than 65(OR=116.597),large volume of blood transfusion(OR=1.01)and high level of triglycerides(OR=37.249)were the risk factors for the occurrence of DVT after the THA.[Conclusion]Female,old age,obesity,increase of the level of triglycerides and cholesteral,O blood type,large volume of blood transfusion and patients with diabetes or hypertension raised possibility the occurrence of DVT.Based on this research,it concludes that patients older than 65,large volume of blood transfusion and high level of triglycerides are the risk factors for the occurrence of DVT after the THA,doctors should control the total dose of blood transfusion,to reduce the dose per time and increase the times of massive blood transfusion.Besides these,both clinicians and doctors performing Color Doppler ultrasonography should pay attention to the calf intermuscular DVT.
