It is usually caused by a blood clot that originates in the deep veins of the lower extremities or elsewhere in the body.
1. Symptoms of pulmonary embolism
The most common symptoms of pulmonary embolism, which usually have an acute onset, include:Chest pain: The pain is often described as pleuritic, with muscle pain that gets worse or sharp when the person takes a deep breath. Shortness of breath: The person may have difficulty breathing at rest and the shortness of breath may be worse with activity. Hypoxia: Decrease in blood oxygen levels Signs such as: Blood pressure, heart rate, breathing rate, and oxygen saturation can be normal or abnormal, depending on the size of the clot causing the embolism and the extent of the blood clot. effect on lung tissue. The larger the clot, the less stable the vital signs. Abnormal vital signs may include:
Tachycardia Tachypnea Low blood pressure Hypoxia: Decreased SaO2 levels. Oxygen saturation describes how many hemoglobin molecules are carrying oxygen. Normal oxygen levels are usually greater than 92%-93%.

2. Complications of pulmonary embolism
Because the organs are deprived of the oxygen needed to function, the person suffers from anxiety, fatigue, and dizziness. If the clot is large enough, it can make it harder for the heart to pump blood through the blocked pulmonary arteries, increasing the burden on the heart, increasing pressure inside the heart, and straining the heart muscle. Sudden death is a common complication of pulmonary embolism. The patient collapses, stops breathing, and goes into cardiac arrest without any prior warning symptoms.3. The role of chest X-ray in the diagnosis of pulmonary embolism
A chest X-ray is done to create pictures of your heart, lungs, blood vessels, airways, chest bones, and spine. A chest X-ray may also show fluid in or around the lungs or air around the lungs. If you have symptoms of chest pain, chest trauma, or difficulty breathing, you will have a chest X-ray first. Chest X-ray images will help your doctor determine if you have heart problems, collapsed lungs, pneumonia, broken ribs, emphysema, cancer, or any other condition. However, chest x-ray cannot confirm a diagnosis of pulmonary embolism and even chest x-ray may appear normal while patient has pulmonary embolism, but chest x-ray can be helpful. effective in helping doctors rule out certain conditions with symptoms similar to pulmonary embolism.

Blood tests Computed tomography computed tomography scintigraphy, pulmonary perfusion scintigraphy (V/Q scans) Pulmonary angiogram MRI . This may be a good option if you are pregnant or if your doctor is concerned that a diagnostic technique that uses contrast material could be dangerous for the patient. Echocardiography . Although echocardiography does not detect pulmonary embolism, the technique is useful for detecting cardiac overload. Pulmonary embolism can be difficult to diagnose, especially in people with a history of heart or lung disease. For that reason, your doctor will ask about your medical history, do a physical exam, and, especially, will order certain types of tests or imaging techniques such as X-rays, blood tests, etc. CT scan...
Currently, at Vinmec International General Hospital, fibrinolysis is being applied to emergency treatment of patients with pulmonary embolism. With modern imaging equipment, CT perfusion results are available within 7 minutes and performed routinely.
The technique is performed by a team of qualified and experienced medical doctors at Vinmec medical system nationwide.
