Dissection study and mensuration of the pulmonary arteries in man

Abstract Descriptions are given of the main pulmonary arteries and of their lobar branches in man. The numbers of lobar branches and certain dimensions (mainly external diameters) of parent vessels (at specified fixed points) and of branch vessels (at their origins) are also given. This information has been obtained from studies made in living subjects. Attention is drawn to the relative frequency of incidence of a large proximally sited branch to the upper lobe in both lungs, also to the site of origin of the lower lobe apical artery, relative to the middle lobe artery or lingular artery. Certain anomalous and small arterial branch arrangements are described.
