Flow-augmentation device for peripheral vascular Doppler US.
To augment venous blood flow at Doppler ultrasonography (US) of the extremities, a device comprising a blood pressure cuff connected to an external reservoir was tested. Constant and easily controlled pressure was delivered with each compression by the same operator performing US. In 10 patients (four men and six women, aged 54-86 years), discomfort was reduced compared with discomfort during manual compression, which requires two operators.
