pulmonary emboli), (2) elevated left atrial pressure (mitral stenosis), (3) thickening of pulmonary arterial and arteriolar walls (scleroderma), (4) derangement and destruction of alveolar walls with damage to pulmonary capillaries in proximity (interstitial lung disease), (5) left-to right shunting increasing blood flow in the pulmonary circulation
(congenital cardiac anomalies), and (6) pulmonary vasoconstriction caused by hypoxemia, hypercapnia, and acidemia (COPD).
In our case the thrombus migrated through the hypoplastic IVC to the level of the pulmonary circulation
and determined a minimum symptomatology, due to repeated microembolisms.
Anatomical shunts arise where there are arteriovenous malformations in the pulmonary circulation
and, outside the lungs, due to congenital heart malformations (eg patent ductus arteriosus or septal defects).
The drug exerts selective vasodilatory action on pulmonary circulation
and also prolongs and enhances the effects of inhaled iloprost (1).
Massive haemoptysis usually originates from the bronchial circulation (95%) rather than the pulmonary circulation
Role of endothelium-derived relaxing factor during transition of pulmonary circulation
He hypothesized that micro-emboli that originate on the device leads pass through the PFO and into the pulmonary circulation
, causing increased pulmonary-artery pressures during the year after device placement.
In many congenital heart diseases, the ductal patency is essential to maintain adequate systemic or pulmonary circulation
to sustain life after birth.
Thrombus can develop anywhere in the body; however, with VTE, the venous thrombi predominately originate within the venous valves of the calf veins and travel through the venous circulation to the right atrium, right ventricle, and then into the pulmonary circulation
where the thrombi eventually lodge in the pulmonary arteries (pulmonary emboli).
Membrane receptors, channels and transporters in pulmonary circulation
Oral prostaglandin E2 in ductus-dependent pulmonary circulation
In the centres of Islamic science, scientists discovered pulmonary circulation
, theorised about flight, invented algebra, calculated the world's circumference and fine-tuned everything from chemistry to optics.
