Objective: This study was undertaken to determine the quantitative augmentation response in several veins examined in a cohort assembled to permit comparisons by sex, age, and ethnicity, under normal conditions and in the presence of obstruction, with and without trophic changes. Method: The common femoral vein, superficial femoral vein, sapheno-femoral junction, popliteal vein, sapheno-popliteal junction, and posterior tibial vein were studied with duplex ultrasonographic scanning. Augmentation response was elicited with use of an automated cuff inflator. Mean level of each response was analyzed according to patient sex, age, and ethnicity, each adjusted for the other two. Normal values were compared with those obtained from legs with venous obstructive disease, with or without signs of trophic changes. Results: Decreased augmentation response was noted only in the sapheno-femoral junction and sapheno-popliteal junction, and was smaller in women. Augmentation response was slightly increased in the oldest age group (>70 years) in the common femoral vein, superficial femoral vein, popliteal vein, and posterior tibial vein. The highest augmentation response was found in Asian subjects, in the common and superficial femoral veins and the sapheno-femoral and sapheno-popliteal junctions; and the smallest augmentation response was found in African American subjects, in these same veins and junctions. Differences in vein diameters may explain these findings, ie, smaller diameters in Asians and larger diameters in African Americans. Most important, compared with normal values, augmentation response was decreased in legs with venous obstructive disease only when trophic changes were present. Conclusion: Like quantification of reflux, quantitative evaluation of the augmentation response may help in diagnosis of venous obstructive disease when trophic changes are present.
