Constant relationship of pulmonary artery and vein to airways. Aorta. Q: What is Curves anteriorly and superiorly over upper lobe bronchus. Divides into three.

What are the distinguishing characteristics between veins and arteries Course of veins is remote from artery Veins begin in lung periphery Arteries are in center of lobules Veins and arteries are separated by lungs Veins run lateral or inferior to respective arteries Horizontal topography of veins while arteries have a vertical course especially in lower lobes CT recognition Q: Click to look at the section at the level of Carina.


Identify the labeled structures. Artery lies just medial to bronchus Right superior pulmonary vein. Vein just lateral to bronchus Q: You are looking at section at the level of RUL bronchus at or just below carina. RUL bronchus originates more cephalad than LUL bronchus Above the right main pulmonary artery Posterior wall is in contact with either posterior segment of RUL or superior segment of RLL Truncus anterior first major branch of right pulmonary artery lies anterior to RUL bronchus Branch of right superior pulmonary vein lies at the angle between anterior and posterior segmental bronchi Anterior and medial to truncus anterior lies RUL vein the apical-anterior vein Q: The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration.


This is measured by inserting a catheter into the main pulmonary artery. The wedge pressure may be elevated in left heart failure[10]: Pulmonary hypertension is used to describe an increase in the pressure of the pulmonary artery, and may be defined as a mean pulmonary artery pressure of greater than 25mmHg. This may arise from a deep venous thrombosisespecially after a period of immobility.

A pulmonary embolus is a common cause of death in patients with cancer and stroke.

Further investigation to include more variant origins of benign lesions and different histologic types of malignancy is needed. Because we have difficulty tracing the pulmonary arteries at this region with confidence, this may cause the routine application of our results to have limitations in evaluating these very peripherally located small lesions.

Conclusion In this study, we have shown that the relationships of the pulmonary arteries to lung lesions and the degree of pulmonary arterial encasement could help in differentiating benignancy from malignancy in lesions, not only for central lung lesions, but also for peripheral lung lesions located below the 2nd-order bronchus to 2 cm away from pleura.
