Abstract: Objective: To investigate the clinical effects of SUT ultrasonic scanning therapeutic apparatus combined with atorvastatin in the treatment of the carotid plaque and low density lipoprotein(LDL). Methods: A total of 240 patients with carotid plaque diagnosed by carotid artery color ultrasound were randomly divided into the control group and combination group according to the random number table method(120 cases each group). The control group and combination group were treated with atorvastatin and SUT ultrasound scanner combined with atorvastatin, respectively. The carotid plaque property and area, and LDL level between two groups were analyzed before treatment, and after 3 and 6 months of treatment. Results: After 6 months of treatment in the combination group, the carotid plaque property tended to stabilize, the carotid plaque area reduced significantly and the LDL decreased significantly(P<0.01). The differences of the carotid plaque area and LDL between two groups were statistically significant after 6 months of treatment(P<0.01). Conclusions: The treatment of carotid plaque with SUT ultrasonic scanning therapeutic apparatus combined with atorvastatin can make carotid plaque stable and shrink, and effectively reduce the level of LDL.
