Pulmonary thromboembolism (PTE) is a medical emergency that occurs when a blood clot (thrombus) travels from another part of the body and lodges in the pulmonary arteries, which supply blood to the lungs. This can lead to impaired blood flow to the lungs, reduced oxygenation, and potentially life-threatening complications such as pulmonary infarction, pulmonary hypertension, or even death.
PTE is often caused by deep vein thrombosis (DVT), which occurs when a blood clot forms in a deep vein, typically in the legs or pelvis. The clot can break free and travel to the lungs, where it becomes lodged in the pulmonary arteries. Other risk factors for PTE include surgery, immobility, cancer, pregnancy, smoking, and certain medical conditions such as heart failure or atrial fibrillation.
Symptoms of PTE can vary depending on the size and location of the blood clot, and may include sudden onset of shortness of breath, chest pain, cough, rapid heart rate, and lightheadedness or fainting. Diagnosis of PTE typically involves a combination of imaging studies, such as CT scan or pulmonary angiography, and blood tests to assess for markers of clotting.
Treatment of PTE usually involves the use of anticoagulant medications, such as heparin or warfarin, to prevent further clot formation and allow the body to break down the existing clot. In more severe cases, thrombolytic therapy may be used to dissolve the clot more rapidly. Surgery may also be necessary in some cases to remove the clot or repair damage to the pulmonary arteries.
Prevention of PTE is important, particularly in high-risk patients. This may involve the use of prophylactic anticoagulation, early mobilization after surgery, and lifestyle modifications such as smoking cessation and regular exercise.
