Handheld vascular Doppler
A handheld pocket device with an ultrasound probe that emits an audible signal upon detecting pulsatile blood flow.
How it is used
Used intraoperatively and in vascular examination to confirm the patency of a vessel or anastomosis when the pulse is not palpable.
Clinical tip
A normal triphasic signal indicates healthy arterial flow, while a monophasic signal suggests significant proximal stenosis.
