title: Photoplethysmography in the diagnosis of superficial venous valvular incompetence.
abstract: Photoplethysmography was compared with clinical investigation combined with Doppler ultrasonography in the diagnosis of superficial venous valvular incompetence of the lower limb. In 268 consecutive patients, 536 limbs were investigated. A total of 22.1 per cent of the photoplethysmographic investigations were uninterpretable because they did not allow reliable determination of the refilling time. Agreement between clinical investigation combined with Doppler ultrasonography and photoplethysmography was found to be poor (kappa = 0.30). These results suggest that photoplethysmography is not the non-invasive method of choice for routine evaluation of superficial venous valvular incompetence of the leg.
