This study assessed main pulmonary artery diameter of patients with anthracofibrosis. Patients with anthracofibrosis and CT scans were evaluated after exclusion of patients with co-existing disease. We measured the diameter of the main pulmonary artery (PAD) and ascending aorta (AD) and calculated the pulmonary artery to aorta ratio (APR). The upper reference limit for comparison of PAD was 29 mm. Cut-off values for PAD and APR indicating pulmonary hypertension were 33 mm and 1. We correlated the CT parameters with echocardiographic results. Total 51 patients were included in the analysis. The mean PAD, AD, and APR were 33 mm, 38 mm, and 0.87 respectively. The PAD was larger than the upper reference limit, 29 mm (P %26lt; 0.001). The PAD was %26gt; 33 mm in 30 (65%) and the APR was %26gt; 1 in 9 patients (18%). Of 21 patients with echocardiography, 11 (52%) were found to have pulmonary hypertension. There was no statistical difference in the diagnosis of pulmonary hypertension between echocardiography and CT (P = 1.000). In conclusion, main pulmonary artery is dilated in patients with anthracofibrosis more than in the healthy population.
