OBJECTIVE: To evaluate the efficacy of intravenous ultrasound microbubbles for thrombolysis of arterial thrombus without using thrombolytic drugs.
METHODS: Twelve rabbit models of acute bilateral femoral artery thrombosis were established and 6 of them received transcutaneous ultrasound and intravenous albumin microbubble treatment for thrombosis on one side while only microbubble treatment for the other side. The other 6 rabbits received ultrasound treatment on one side but no treatment on the other to serve as the control group.
RESULTS: None of the 6 arteries treated with microbubbles alone and only 2 arteries treated with ultrasound alone in the 6 control rabbits were recanalized. All the 6 femoral arteries treated with microbubbles together with ultrasound were recanalized (P=0.014), with significantly shorter patent time and smaller residual thrombus cross-sectional area than those of the arteries with only ultrasound treatment (P=0.004 and P=0.003, respectively).
CONCLUSION: Treatment with intravenous microbubbles assisted by transcutaneous ultrasound effectively promotes arterial thrombolysis in vivo, and this technique can be of significance in clinical treatment of acute thrombotic occlusions.
