  2. Pulmonary artery - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_artery

    A pulmonary artery is an artery in the pulmonary circulation that carries deoxygenated blood from the right side of the heart to the lungs. The largest pulmonary artery is the main pulmonary artery or pulmonary trunk from the heart , and the smallest ones are the arterioles , which lead to the capillaries that surround the pulmonary alveoli .

  3. Pulmonary circulation - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_circulation

    Pulmonary embolism is occlusion or partial occlusion of the pulmonary artery or its branches by an embolus, usually from the embolization of a blood clot from deep vein thrombosis. [10] It can cause difficulty breathing or chest pain, is usually diagnosed through a CT pulmonary angiography or V/Q scan , and is often treated with anticoagulants ...

  4. Pulmonary angiography - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_angiography

    Selective pulmonary angiogram revealing significant thrombus (labelled A) causing a central obstruction in the left main pulmonary artery. Pulmonary angiography (or pulmonary arteriography,conventional pulmonary angiography, selective pulmonary angiography) is a medical fluoroscopic procedure used to visualize the pulmonary arteries and much less frequently, the pulmonary veins.

  5. CT pulmonary angiogram - Wikipedia

    en.wikipedia.org/wiki/CT_pulmonary_angiogram

    A CT pulmonary angiogram (CTPA) is a medical diagnostic test that employs computed tomography (CT) angiography to obtain an image of the pulmonary arteries. Its main use is to diagnose pulmonary embolism (PE). [ 1 ]

  6. Angiography - Wikipedia

    en.wikipedia.org/wiki/Angiography

    One of the most common angiograms performed is to visualize the coronary arteries. A long, thin, flexible tube called a catheter is used to administer the X-ray contrast agent at the desired area to be visualized. The catheter is threaded into an artery in the forearm, and the tip is advanced through the arterial system into the major coronary ...

  7. Major aortopulmonary collateral artery - Wikipedia

    en.wikipedia.org/wiki/Major_aortopulmonary...

    Major aortopulmonary collateral arteries (MAPCAs) develop early in embryonic life but regress as the normal pulmonary arteries (vessels that will supply deoxygenated blood to the lungs) develop. [2] In certain heart conditions the pulmonary arteries do not develop. The collaterals continue to grow, and can become the main supply of blood to the ...

  8. Pulmonary wedge pressure - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_wedge_pressure

    Diagram of a pulmonary artery catheter in position. The pulmonary wedge pressure (PWP) (also called pulmonary arterial wedge pressure (PAWP), pulmonary capillary wedge pressure (PCWP), pulmonary artery occlusion pressure (PAOP), or cross-sectional pressure) is the pressure measured by wedging a pulmonary artery catheter with an inflated balloon into a small pulmonary arterial branch. [1]

  9. Artificial ventilation - Wikipedia

    en.wikipedia.org/wiki/Artificial_ventilation

    Artificial ventilation or respiration is when a machine assists in a metabolic process to exchange gases in the body by pulmonary ventilation, external respiration, and internal respiration. [1] A machine called a ventilator provides the person air manually by moving air in and out of the lungs when an individual is unable to breathe on their own.
