[The pulmonary artery size variability during various stages of post-fetal life in man]

Fresh lungs (45 right and 40 left) from dead bodies of 50 (30 male and 20 female) people from 1 to 80 years were examined. The pulmonary arteries were injected for 65% duracryl solution (Spofa-Dental firm) and after maceration the preparations were measured. Pulmonary arteries indices were also calculated. Pulmonary arteries diameter in male measured from 9.0 to 24 mm, average 17.0 mm, in female--from 7.4 to 28 mm, average 18.7 mm. The difference between the right and left pulmonary artery size was statistically significant, both in male and female persons. The correlation indices between size of male right pulmonary artery and age, length and body weight amounted to 0.70, 0.61 and 0.53, while for left pulmonary artery--0.58, 0.55 and 0.49. The same indices of female specimens valued for right pulmonary artery 0.72, 0.58 and 0.51. The size of the left pulmonary artery was correlated only with age (index 0.65).
