Failure of quantitative venous photoplethysmography to assess venous insufficiency: a prospective clinical study.

摘要: The increase of deep venous reconstructive surgery necessitates reliable tests for evaluation the results, which requires quantization expelled volume. This could only be done with invasive measurements, but now it seems possible to calibrate photoelectric cells, and quantize results. Nineteen limbs patients disease seven healthy volunteers were evaluated, methods known from literature. In addition measurements in standing position, these used more patient-friendly sitting position. Invasively noninvasively measured recovery times correlated well (R = 0.83) position 0.86). However, volume did not significantly correlate. Also, differences between controls significant (P 0.006) as 0.004). noninvasive method. our opinion, cells still do offer an alternative results after surgery.
