What are the symptoms and diagnosis of pulmonary embolism in children?

Symptoms of pulmonary embolism in children include chest pain, hemoptysis, dyspnea, etc. It can be diagnosed by clinical manifestations, radionuclide pulmonary ventilation/blood perfusion imaging, pulmonary angiography, etc.

, hemoptysis

pulmonary embolism can lead to alveolar wall and endobronchial wall rupture, resulting in bronchial varices, causing bleeding, blood through the oral discharge will be manifested as hemoptysis.

3, dyspnea

pulmonary embolism can cause bronchospasm, reduce ventilation. At the same time, pulmonary embolism, pulmonary capillary permeability will also increase, so that pulmonary interstitial and alveolar fluid increase, affecting the ventilation area, and then lead to dyspnea.

2. Radionuclide pulmonary ventilation/blood perfusion imaging

This examination can understand the blood supply of the lungs and is of great significance for the diagnosis of pulmonary embolism.

3. Pulmonary arteriography Pulmonary

arteriography can clearly observe whether there is stenosis and blockage in the pulmonary artery, and the degree of stenosis and blockage, which can help diagnose pulmonary embolism.
