|Color coded Duplex Sonography
The color coded duplex sonography allows for a visible projection of the surface- and deep vein systems without a contrast agent and reveals venous valve damages, vascular dilation and constrictions as well as calcium deposits. With this diagnostic method, arteries and veins can be projected in color. This allows for an exact thrombosis diagnosis, the pain free identi-fication of circulatory disorders as well as progress- and post-operative monitoring.
The ultrasound-Doppler Sonography is used to recognize arterial and venous circulatory dis-orders as well as arterial blood pressure. Furthermore, the extent of venous valve damages and blood flow direction can be measured.
The LRR-method is necessary for basic diagnostic purposes. It measures the venous return flow and indicates how fast the venous blood is settling in the leg. This method has been de-signed to determine if surgery is necessary to improve the venous return flow. Sometimes an X-ray projection of the vessels with a contrast agent (Phlebography) becomes necessary prior to a scheduled operation in order to exactly determine the expansion of the varicose veins, especially if an earlier similar procedure has been performed.
Vein Occlusion Plethysmography
The vein occlusion plethysmography is used to measure the vein capacity and shows the venous backflow as well as possible outflow blockages.
