Abstract
A method of measuring column interruption duration in a selected lower leg vein of a patient without undertaking dorsal foot measurements. The method includes the step of selecting a vein in the lower leg to be examined and selecting a valve in the vein to be observed. The valve's actions will be observed with Duplex ultrasound and timed. The method then effects calf muscle ejection and observing the action of the selected valve in the respective vein selected. The valve can be observed for opening or closing action, or action of blood flow (or lack of flow) through the valve. The CID is then determined calculated based on the timing of events observed with ultrasound. The ultrasound can be Duplex ultrasound; invasive measurements are not required.
