Abstract:
Objective To investigate the value of ultrasonography in evaluating the femoral artery thrombosis in rabbit. Methods Thrombosis was induced by external application with 10% ferric chloride and transient femoral artery-occlusion with bulldog clamp in twenty New-Zealand rabbits. The thrombosis was monitored by both Doppler flowmeter and ultrasonography. The histopathological result was used as the golden standard. The consistency of the above two results with the golden standard was analyzed. Results Thirty-two femoral arteries thrombosis were produced successfully. There was high consistency between the results of ultrasonic evaluation and histopathological examination (Kappa = 0. 720, P ＜ 0. 001 ), and moderate consistency between the results of Doppler flowmeter evaluation and histopathological examination (Kappa = 0. 546, P ＜0. 001 ). Within the thirty-two femoral arteries thrombosis, there were nineteen arteries with occlusive thrombus examined by histopathological means. Both the results of Doppler flowmeter and ultrasonography were highly consistent with the results of histopathological examination (Kappa = 0. 800 and 0.798 respectively, P ＜ 0. 001 ). Conclusions There is high consistency between the results of ultrasonic evaluation and histopathological examination for the common femoral artery thrombosis in rabbit.In the non-occlusive thrombus diagnosing,ultrasonography is better than Doppler flowmeter.
