Evaluation of indirect blood pressure measurement as a method of assessment of peripheral vascular disease. 1977

R O Quin, and D H Evans, and T Fyee, and P R Bell

In over 200 patients with peripheral vascular disease, pressure index (formula: see text) was compared with radiological grade; although calf P.I. had a better correlation, there was wide overlap between the groups. In 28 patients, resting calf P.I. was compared with functional impairment measured on a treadmill. At two rates of exercise, calf P.I. correlated poorly with functional impairment. In 35 patients, reproducibility of indirect pressure measurement was assessed; coefficients of variation ranged 0-10%; coefficient of variation of calf P.I. ranged 0-8%; coefficient of variation of calf P.I. ranged 0-8%. In 12 patients, indirect thigh systolic pressure was compared with and nearly always exceeded direct common femoral artery pressure; this was due to an effect of the cuff which reduced blood flow and reduced the pressure gradient. This methodological error has not previously been described and reduces the clinical value of the measurement.

UI	MeSH Term	Description	Entries
D007383	Intermittent Claudication	A symptom complex characterized by pain and weakness in SKELETAL MUSCLE group associated with exercise, such as leg pain and weakness brought on by walking. Such muscle limpness disappears after a brief rest and is often relates to arterial STENOSIS; muscle ISCHEMIA; and accumulation of LACTATE.	Claudication, Intermittent
