Artificially colored 3D rendering of a high resolution computed tomography of a normal thorax of a 37 year old man who presented with unspecific breathing problems, published with written informed consent. The anterior thoracic wall, the airways and the pulmonary vessels anterior to the root of the lung have been digitally removed in order to visualize the different levels of the pulmonary circulation.

The pulmonary trunk or main pulmonary artery (mPA) is the solitary arterial output from the right ventricle, transporting deoxygenated blood to the lungs for oxygenation.

Gross anatomy

The pulmonary trunk is approximately 50 mm long and 30 mm wide (most authors use 29 mm in males and 27 mm in females (axial width) as the cut-offs of normal ). It arises as a direct superior continuation of the right ventricular outflow tract, separated by the pulmonary valve. As it ascends it slants posteriorly and to the left of the ascending aorta. With the ascending aorta, the pulmonary trunk is invested in a common sheath of serous visceral pericardium, anterior to the transverse pericardial sinus.

At the level of the transthoracic plane, the trunk emerges from the fibrous pericardium and divides into the longer right and shorter left pulmonary arteries in the concavity of the aortic arch, anterior to left main bronchus and to the left of the carina.

The left coronary artery passes between the pulmonary trunk (on the left) and the auricle of the left atrium.
