Pulmonary artery stenosis (PAS) is a narrowing of the pulmonary artery.The pulmonary artery is a blood vessel moving blood from the right side of the heart to the lungs. . This narrowing can be due to many causes, including infection during pregnancy, a congenital heart defect, a problem with blood clotting in childhood or early adulthood, or a genetic ch
The outcome of treatment is dependent on causality. Pulmonary Hemorrhage is present in 7 to 10% of neonatal autopsies, but up to 80% of autopsies of very preterm infants. [1] The incidence is 1 in 1,000 live births. [1] Pulmonary hemorrhage has a high mortality rate of 30% to 40%. [1]
The current clinical classification system for tuberculosis (TB) is based on the pathogenesis of the disease. [1] Health care providers should comply with local laws and regulations requiring the reporting of TB. All persons with class 3 or class 5 TB should be reported promptly to the local health department. [2]
The causes of pulmonary heart disease (cor pulmonale) are the following: Acute respiratory distress syndrome (ARDS) [10] COPD [2] Primary pulmonary hypertension [2] Blood clots in lungs/Pulmonary embolism [2] Kyphoscoliosis [2] Interstitial lung disease [2] Cystic fibrosis [2] Sarcoidosis [11] Obstructive sleep apnea (untreated) [2] Sickle cell ...
[2] A majority of tuberculosis infections affect the lungs, and extra-pulmonary tuberculosis infections account for the remainder; these most commonly involve the lymphatic system. [3] Although the cervical region is most commonly affected, tuberculous lymphadenitis can occur all around the body, including the axillary and inguinal regions. [4]
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 ...
A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
It can be attributed to various etiologies including pulmonary embolism, pneumothorax, pericarditis, and viral pleurisy. [18] Tuberculosis: Tuberculosis is caused by Mycobacterium tuberculosis, which primarily infects the lungs, leading to Granuloma formation as the immune system walls off the bacteria. Symptoms include chronic cough, fever ...
