9. PAVM (Pulmonary Arteriovenous Dysfunction)
PAVM is a disorder that affects blood flow between the heart and lungs. Affected individuals have a defective pulmonary vein-to-pulmonary artery connection. The two main veins carrying blood from the lungs to the heart and from the heart to the lungs are the pulmonary vein and the pulmonary vein. This condition impairs oxygenation of the blood in the lungs.
The weak walls of the affected blood vessels occasionally enable blood to leak into the lung. This results in coughing up blood from the airways. In other instances, bacteria and clots present in the lung would become confined between small capillaries and then pass through the AVM to brain-supplying blood vessels. In such extreme cases, a stroke or brain abscess may result. AVM is identified through screening for cerebral arteriovenous malformation. Noting that AVMs do not resolve on their own and that medical intervention is required is essential.
