[Quantitative flow determinations in the superior femoral artery and the popliteal artery using angiodynography (color-coded duplex sonography) before and after percutaneous transluminal laser angioplasty]. / Quantitative Flussbestimmungen in der A. fem. sup. und A. poplitea mit der Angiodynographie (Farbkodierte Duplexsonographie) vor und nach perkutaner transluminaler Laserangioplastie.

The primary angiographic PTLA-success correlates with the angiodynographically measured blood flow. 24 hours after the treatment the measured flow values in the AFS and AP allow prognoses: 1. Flow volumes in the AP less than 15 ml/min do not allow successful PLTA-therapy. 2. Slight clinical improvement can be expected for flow values greater than 50 ml/min in the AFS and between 20 and 30 ml/min in the AP. 3. AP-values greater than 30 ml/min correlate in this pilot investigations with an excellent clinical result 4 months after intervention.
