Introduction
Pulmonary Embolism (PE) is a potentially life-threatening condition that occurs when a blood clot, typically originating from the deep veins of the legs, travels to the lungs and blocks one or more pulmonary arteries. This obstruction can disrupt blood flow to the lungs, leading to serious complications such as pulmonary infarction and even death if not promptly diagnosed and treated. Despite advances in medical knowledge and technology, pulmonary embolism remains a significant cause of morbidity and mortality worldwide.[1,2].
Several factors contribute to the development of pulmonary embolism. The most common cause is deep vein thrombosis where blood clots form in the deep veins of the legs or pelvis. These clots can break loose and travel through the bloodstream to the lungs, causing a blockage. Other risk factors for pulmonary embolism include prolonged immobilization, surgery, trauma, obesity, smoking, hormonal contraceptive use, pregnancy, and certain medical conditions such as cancer and inherited blood clotting disorders. Additionally, individuals with a history of previous venous thromboembolism or a family history of the condition are at higher risk.The symptoms of pulmonary embolism can vary widely depending on the size and location of the blood clot, as well as the individual's overall health status. Common symptoms include sudden onset of chest pain, shortness of breath, rapid heart rate, coughing (sometimes with blood), and dizziness or fainting. However, it's important to note that not all individuals with pulmonary embolism experience these classic symptoms, and the condition can present with subtle or nonspecific signs, especially in elderly patients or those with underlying medical conditions. This makes diagnosis challenging and underscores the importance of maintaining a high index of suspicion, particularly in high-risk individuals [3,4].
Diagnosing pulmonary embolism requires a combination of clinical assessment, laboratory tests, and imaging studies. A thorough medical history and physical examination can help identify risk factors and guide further evaluation. Laboratory tests such as D-dimer, a marker of blood clot breakdown, may be elevated in individuals with suspected pulmonary embolism but are nonspecific and require confirmatory imaging studies. The gold standard for diagnosing pulmonary embolism is contrast-enhanced computed tomography pulmonary angiography which allows for visualization of blood clots within the pulmonary arteries. Other imaging modalities, such as ventilation-perfusion scanning and echocardiography, may be used in certain clinical scenarios.[5,6].

The prognosis of pulmonary embolism varies depending on factors such as the size and location of the blood clot, the presence of underlying medical conditions, and the timeliness of diagnosis and treatment. In general, prompt recognition and appropriate management can significantly improve outcomes and reduce the risk of complications such as chronic thromboembolic pulmonary hypertension and recurrent venous thromboembolism. However, untreated or undertreated pulmonary embolism can lead to hemodynamic instability, respiratory failure, and death, underscoring the importance of early intervention and vigilant monitoring of high-risk individuals.[
