Abstract
This study was conducted to investigate the accuracy and agreement between clinical examination, continuous wave (cw)-Doppler ultrasound and colour-duplex sonography (CDS) in diagnosing incompetent perforating veins (ICPV). Observational cohort study. Nineteen patients with chronic venous insufficiency (CVI) were examined clinically, by hand-held cw-Doppler ultrasound in combination with tourniquet compression and CDS. The low accuracy of the clinical examination and the diagnosis of ICPV by cw-Doppler were surprising. The specificity was 15% and sensitivity 29%, when CDS was taken as the "gold standard". Furthermore the results show clearly that the application of a tourniquet cannot provide reliable results. In patients with CVI, clinical and cw-Doppler cannot accurately diagnose ICPV when compared to CDS.
