Although ligustrazine was equally potent in inducing dilatation of pulmonary and bronchial arteries, it was about 10 times more potent in relaxing small pulmonary arteries (300–500 μm i.d.) compared with lobar pulmonary arteries (7–8 mm i.d.). By contrast, the relaxant responses of ...
The human bronchial arteries and their anastomoses with pulmonary vessels were studied on normal and diseased lungs in 30 adult and infant cadavers under a magnification of 3～40 times.The bronchial arteries pursue a tortuous serpentine course along the surface of the bronchi. They divide either bef...
In particular, CCT showed a large vascular malformation (17x17x9 mm) constituted by multiple fistu-lous communications between coronary arteries, bronchial arteries, and the pulmonary (Panels A–I; Supplementary material on line, Video S1–3). Coronary angiography confirmed the presence of numerous...
Answer to: Blood supply to the lungs is derived from: (a) Pulmonary arteries (b) Pulmonary veins (c) Bronchial arteries (d) Bronchial veins. By...
The segmental arteries are seen near the accompanying branches of the bronchial tree and are situated either medially (in the upper lobes) or laterally (in the lower lobes, lingula, and right middle lobe). View Image The pathophysiology of pulmonary embolism. Although pulmonary embolism can arise...
A patient with long-standing thrombosis of the left main pulmonary artery complicated by unilateral pulmonary disease and bronchial-pulmonary arterial shunt is described. The benign clinical course, roentgenologic findings of equal density of both lung fields and elements resembling a unilateral hyperlucen...
Embolization of bronchial arteries in patients with hemoptysis: Influence of underlying pathology on outcome Purpose: To evaluate the influence of underlying pathology on the control of hemoptysis by transcatheter embolization of bronchial arteries. Methods: Trans... J García-Medina,M Casal,A Fernández...

In addition, there is hypertrophy of the muscular coat of the intra-acinar arteries and veins (see Chapter 7). It is not entirely clear why growth of the lungs, and proliferation of pulmonary vessels, is limited. Muscular hypertrophy of the walls of the vessels is probably secondary to the...
In the upper lung zones, the pulmonary artery diameter in an erect film is 85% of the adjacent bronchial diameter. In the lower lung zones, the pulmonary arteries are one-third bigger than the nearby bronchus. Pattern Recognition The first step in analyzing the pulmonary vasculature is to ...
