Sonodynamic Therapy Manipulates Atherosclerosis Regression Trial on Patients With PAD and Claudication

OMC is established according to the 2016 ACC-AHA Guidelines for the Management of Patients with PAD. Pseudo-SDT combines saline injection and obstructed ultrasound exposure on targeted lesions to simulate real SDT progression.

OMC is established according to the 2016 ACC-AHA Guidelines for the Management of Patients with PAD. SDT treatment is the combination of sonosensitizer administration and target atherosclerotic lesions ultrasound exposure. Sinoporphyrin sodium (DVDMS) as sonosensitizer, is dissolved in 0.9% sodium solution for following skin test and intravenous injection. 0.01mg/ml DVDMS solution (0.1ml) is prepared for skin test followed by 0.04 mg/ml.DVDMS solution intravenous injection (0.2mg/kg). The target atherosclerotic lesions are marked on the corresponding skin with ultrasound guidance and underwent ultrasound exposure after 4 hours incubation. The therapeutic ultrasonic transducer is fixed to the marked skin site of each lesion.
