Terms in this set (17)

B. Venous Reflux
A venous Doppler exam of the popliteal vein reveals a sustained flow signal upon release of distal compression. This would indicate which of the following?

C. High cardiac output and intimal injury
D. Intimal injury, hypercoagulability and poor stroke volume
D. Iliac Vein obstruction
Continuous, non-phasic venous flow unilaterally in a common femoral vein suggests which of the following conditions?

Perforating veins exceeded this diameter have a high predictive value for being incompetent.

A. >1.5 mm
B. >2 mm
C. >2.5 mm
D. >3.5 mm
