Description

A Pulmonary Embolism (PE) is a blockage of a pulmonary artery caused by a material that has travelled through the bloodstream from elsewhere in the body. Breathlessness, chest pain, especially while inhaling, and bloody coughing are all signs of a PE. Leg symptoms, such as a red, heated, swollen, and painful leg, may also be present in blood clots in the legs. Low blood oxygen levels, fast breathing, a quick heartbeat, and occasionally a minor temperature are symptoms of a PE. Severe cases can include obstructive shock, passing out, extremely low blood pressure, and rapid death. PE typically results from a blood clot in the leg that moves to the lung. Advanced age, cancer, extended bed rest and immobility, smoking, stroke, long-distance travel over four hours, specific hereditary diseases, estrogen-based medication, pregnancy, obesity, trauma or bone fracture, and after various forms of surgery all raise the risk of blood clots. Only a small percentage of instances are caused by the embolization of amniotic fluid, fat, or air. Venous thromboembolism is the collective name for deep Vein Thrombosis and PE (VTE). PE can be avoided by moving as soon as feasible following surgery, performing lower leg movements while seated, and using blood thinners after certain procedures. Anticoagulants like heparin, warfarin, or one of the Direct-Acting Oral Anticoagulants (DOACs) are used as a form of treatment. It is advised to use them for at least three months. Surgery and thrombolysis using drugs such as Tissue Plasminogen Activator (TPA) either intravenously or through a catheter may be necessary in severe cases. A temporary vena cava filter may be employed in place of blood thinners if necessary. Symptoms of pulmonary embolism usually appear suddenly and may include one or more of the following: dyspnea, tachypnea, "pleuritic" chest discomfort, cough, and hemoptysis. Cyanosis, collapse, and circulatory instability due to decreased blood flow via the lungs and into the left side of the heart are symptoms of more severe cases. A left parasternal heave, a loud pulmonary component of the second heart sound, and/or elevated jugular venous pressure are all signs of right ventricle strain. There could be a low-grade fever, especially if there is a pulmonary haemorrhage or infarction present. Smaller pulmonary emboli are more likely to result in lung infarction and minor effusions, both of which are uncomfortable, but not hypoxia, dyspnea, or hemodynamic instability like tachycardia since they have a tendency to lodge in more peripheral locations without collateral circulation.

A huge fragmented embolism that causes both large and tiny PEs is most likely what causes the characteristic PE presentation of pleuritic discomfort, dyspnea, and tachycardia. As a result, minor PEs are frequently missed because they only induce pleuritic pain and have no other symptoms, while large PEs are frequently overlooked because they are painless and frequently mirror other illnesses, resulting in ECG abnormalities, small increases in troponin levels, and small elevations in brain natriuretic peptide levels. According on the clinical signs and symptoms, PEs can be classified as large, submassive, or nonmassive. Although the precise definitions of these are unclear, hemodynamic instability is generally considered as a sign of large PE. Obstructive shock is caused by this, which manifests as persistently low blood pressure, a sluggish heartbeat, or pulselessness. An image of the pulmonary arteries is obtained during a CT Pulmonary Angiogram (CTPA), a medical diagnostic procedure that uses Computed Tomography (CT) angiography. Its primary use is to identify Pulmonary Emboli (PE). Due to the patient's minimally invasive nature the scan only requires an intravenous line it is a recommended option for imaging in the diagnosis of PE.

The gold standard for the detection of pulmonary embolism has been replaced by CTPA as a result of the ability of modern Multi- Detector CT (MDCT) scanners to quickly give images with appropriate clarity. Before, direct pulmonary angiography was the procedure of choice. An injector pump is used to administer a high-rate intravenous injection of an iodine-containing contrast material to the patient. In the pulmonary arteries, images are taken while radio-opaque contrast is at its strongest. On a typical CTPA scan, the contrast will be seen filling the pulmonary arteries and will look as dazzling white. Any mass filling inadequacies, such as an embolus, will appear black rather than contrasty and will fill or obstruct the region where blood should be flowing into the lungs. Typically, a CTPA is only requested when a clinical suspicion of pulmonary embolism exists. Depending on how likely PE is, a blood test called D-dimer may be required. CTPA or other scans are typically skipped if this test is negative and the risk of a PE is seen as minimal.
