Why the study?
Does the pulse volume recorder accurately localize arteriosclerotic lesions in the lower limbs compared to clinical examination and simple pressure measurements?

The pulse volume recorder is an accurate tool for localizing isolated stenoses in lower limb arteriosclerosis, particularly when distal pulses are undetectable or severe medial sclerosis is present.

May aid localization of isolated lower-limb stenoses when distal pulses undetectable; hypothesis-generating, requires prospective validation.
The pulse volume recorder has been used in studying 62 limbs to assess its accuracy in localization of arteriosclerotic lesions of the lower limbs, realizing the limitations of clinical examination and simple pressure measurements. Its advantages over simple pressure measurements are illustrated. It was shown to be most accurate in locating isolated stenoses. The technique helps differentiate aorto-iliac from high superficial femoral artery obstruction. It can be used when severe medial sclerosis is present and is very helpful when distal pulses cannot be detected for technical reasons.
