(seep. 6). The major pulmonary arteries are elastic vessels and at birth the pattern of their elastic laminae closely resembles that of the aorta. Within the first few months of life there is fragmentation of theelastic fibresand an irreversible ‘adult pattern’ is reached by about the age ...
Blood must always circulate to sustain life. It carries oxygen from the air we breathe to cells throughout the body. The pumping of the heart drives this blood flow through the arteries, capillaries, and veins. One set of blood vessels circulates blood through the lungs for gas exchange. Th...
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...
The LigaSure device has been demonstrated to be safe for systemic vessels up to 7 mm in diameter, although its use in thoracic surgery remains understudied. We aimed to evaluate the safety of LigaSure for pulmonary artery sealing. In 30 cases of open lung lobectomy, 15 small pulmonary arteries...
Descending or interlobar pulmonary artery, supplies left lower lobe and lingula – Peripheral pulmonary arteries located medial to bronchi in anterior and apicoposterior segments of left upper lobe and lateral to bronchi in lingula and lower lobe ...
genetic mutations. In these situations, the process begins with damage to the endothelial cells lining the pulmonary arteries. Once that happens, the damaged endothelial cells release chemicals like endothelin-1, serotonin, and thromboxane. These chemicals make the pulmonary arterioles constrict and ...
Fibrosing mediastinitis have been mainly reported in sarcoidosis, tuberculosis, histoplasmosis and after radiotherapy. Fibrosing mediastinitis may be associated with severe PH due to compression of both pulmonary arteries and veins. Lastly, PH has been reported in patients with end-stage renal disease mai...
Coronary to pulmonary artery fistula associated with significant coronary atherosclerosis and severe aortic valve stenosis: A Case Report Coronary artery fistulas are anomalous connections between one or two coronary arteries with either a cardiac chamber or any major blood vessels (coronary ... X Krasni...
In PAH lungs without PLs, we analyzed remodeled arteries, which showed concentric laminar intimal proliferation and fibrosis (“concentric lesions” with a diameter of ≤500 μm). Unagitated arterial vessels from downsized lung tissue of donor lungs served as controls. Inflammatory cells in PLs and...
1 Previous studies have shown that idiopathic PAH (IPAH), and PAH occurring in association with congenital heart disease (CHD-PAH) and connective tissue disease (CTD-PAH) have similar pathologies such as medial hypertrophy of muscular and elastic arteries, dilation and intimal atheromas of elastic...
