The decreased transmural pressure increases the intraluminal pressure, which "pushes" the blood from pulmonary vessels
into the left ventricle and increases left ventricular preload.
In addition, studies have shown a 50% reduction in prostacyclin synthase activity in the small pulmonary vessels
of patients with pulmonary arterial hypertension.
The effects by the water-soluble fraction would be more biologically relevant because components in this fraction are more likely than the whole particles or the insoluble fraction to gain access to the pulmonary vessels
quickly by diffusion after the particles are inhaled into the lung.
In this condition, embolic tumor cells obstruct pulmonary vessels
, activate the coagulation cascade (24), and produce inflammatory mediators promoting thrombosis and intimal proliferation (23).
Infants with cardiac shunt lesions develop pulmonary oedema due to the increased hydrostatic pressure in the engorged pulmonary vessels
NO is exceptionally selective as it vasodilators areas of the pulmonary vessels
that are ventilated to the greatest degree.
are of uniform calibre throughout the lung.
To date its application within the pulmonary vessels
has been predominantly described in the treatment of arteriovenous malformations (5).
In old times, the "angiogram sign," in which branching pulmonary vessels
could be visualized normally within areas of consolidation on contrast-enhanced CT, was reported as a specific sign of the pneumonic type of bronchoalveolar cell carcinoma, (70) however, it also can be seen in pneumonia.
7) In a study by Rowley et al, (8) high numbers of IgA plasma cells were found in pulmonary vessels
, the trachea, and peribronchial tissue.
4] was primarily due to constriction of upstream pulmonary vessels
In contrast to pulmonary arterial hypertension, all of the pulmonary vessels
are enlarged in pulmonary overcirculation.
