A patient is having segmental pressure measurements conducted to help diagnose peripheral vascular disease. What finding would indicate the presence of this disorder?
1. thigh pressure higher than the arm
2. calf pressure higher than the arm
3. calf pressure lower than the arm
4. no difference between the arm or leg
Correct Answer: 3
Noninvasive studies often are sufficient to diagnose peripheral vascular disease. Segmental pressure measurements use sphygmomanometer cuffs and a Doppler device to compare blood pressures between the upper and lower extremities and within different segments of the affected extremity. In peripheral vascular disease (PVD), the blood pressure may be lower in the legs than in the arms.
