Doppler waveform analysis and percutaneous dilatation of arteries in ischaemia of the lower limb.

: Percutaneous transluminal dilatation of narrowed atheromatous arteries using the inflatable Gruntzig catheter is becoming an accepted non-surgical treatment for patients with disabling intermittent claudication of the lower limb. The use of doppler ultrasound to study limb blood flow in a group of patients having aortic or iliac dilatation is described.
