The size comparison of the diameter of anterior segmental bronchus and that of anterior segmental artery

Abstract

It is thought to be reliable roentgenologic sign of pulmonary plethora that the diameter of anterior segmental artery(d-ASA) is larger than that of anterior segmental bronchus(d-ASB). To evaluate the reliability of this sign, we compared d-ASA with d-ASB on chest rentgenograms of 100 normal adults. Of the total 105 cases. d-ASA was larger than d-ASB in 40 cases (38.1%), smaller than d-ASB in 34 cases(32.4%) and equal to (d-ASA and) d-ASB in 31 cases(29.5%). The ratio(ABR) and difference between d-ASA and d-ASB ranged from 0.70 to 1.58(mean, 1.05±0.30) and from -1.85mm to +2.45mm(mean of absolute value, 0.75mm±0.57). These results showed that the relationships between d-ASA and d-ASB were variable. Conclusively, d-ASA may be larger than d-ASB in even normal adults and mild degree of pulmonary plethora cannot exectly evaluated with this findings only.
