Abstract
Percutaneous transluminal angioplasty (PTA) is now an established technique, and is particularly useful for the dilatation of iliac stenoses. One of the problems encountered is that the femoral artery to be punctured may not have a palpable pulse because of proximal disease. (Cumberland, 1982). We describe the use of a Doppler ultrasonic flow detector as a non-invasive and accurate method of detecting the position of a “pulseless” femoral artery.
