Abstract:

BACKGROUND: At present, many methods for inducing lower limb venous thrombosis lack of unified standards.
OBJECTIVE: To establish rabbit models of lower limb venous thrombosis after hip facture
METHODS: Hip fracture was induced in rabbits by impacting the root of left leg by a dropping object from a height of 28 cm. The right leg was not impacted and served as the control side. After 4 weeks, the iliac and femoral veins of the lower limbs were selected for color Doppler ultrasonography and blood coagulation examination.
RESULTS AND CONCLUSION: Color Doppler ultrasonography showed that there was a thrombosis area with a length of (124±37) mm in the lower limb deep veins. No lower limb deep venous thrombosis was found in the control side. Thrombosis rate was 81.8% and death rate was 9.1%. These findings suggest that rabbit models of lower limb deep venous thrombosis after hip fracture could be successfully established, and the method is simple and feasible.
