Abstract

Objective: The aim of this study is to determine the normal value of the subcarinal angle in the adult Thai population and whether there is a relationship between the subcarinal angle and the patient’s age, gender, and thoracic shape.
Methods: The chest radiographs of 163 healthy patients were retrospectively reviewed. The subcarinal angle was analyzed with consensus by two radiologists. Quantitative variables are expressed as the mean ± standard deviation of the mean. The relationship of the subcarinal angle with the patient’s age, gender, and thoracic index were analysed using the Pearson correlation method.
Results: A total of 163 patients (75 men and 88 women; age range 21-63 years; mean age 44 years) were enrolled. The mean subcarinal angle was 62o. There was no relationship between subcarinal angle and age, gender, and height or width of the thoracic cage.
Conclusion: There is wide range of normal values for the subcarinal angle. The mean subcarinal angle was 62o. There was no relationship of the subcarinal angle to age, gender, or thoracic shape.
