Pulmonary embolism is a relatively common acute disease in clinical practice. It usually occurs when blood clots from the veins in the legs or pelvis detach, travel through the bloodstream to the pulmonary arteries, and cause an embolism. The onset of this disease is often very sudden. Due to different triggers, the clinical symptoms vary. Typical symptoms of pulmonary embolism include difficulty breathing, chest pain, coughing up blood, and coughing. Coughs are often dry, and patients may also have a small amount of white sputum. Some patients might even experience wheezing and other clinical symptoms. Therefore, the occurrence of excessive sputum is rare in patients with pulmonary embolism.

Can pulmonary embolism cause bloating and abdominal distension?

Pulmonary embolism can, in rare cases, cause bloating and abdominal distension. The primary clinical manifestations of pulmonary embolism are chest tightness and difficulty breathing. Severe pulmonary embolism can also lead to a drop in blood pressure and sometimes may even cause the patient to faint. However, it is important to note that in severe cases of pulmonary embolism, patients may also experience abdominal distension. Patients with pulmonary embolism might also have acute pulmonary heart disease, which could include symptoms of gastrointestinal congestion. In such cases, patients may experience abdominal bloating. Additionally, there is a special condition known as chronic thromboembolic pulmonary hypertension, where patients may experience chronic pulmonary heart disease and chronic hypoxia, which can also lead to abdominal distension.

Is it good to place a filter for pulmonary embolism or not?

Whether it is good or not to place a filter for pulmonary embolism mainly depends on the cause of the pulmonary embolism and whether there are indications for placing a filter. Generally speaking, if pulmonary embolism is caused by the formation of blood clots in the lower limbs or the inferior vena cava, placing a filter can generally be beneficial. However, not all cases of lower limb venous thrombosis require a filter. Filters are usually only used for deep or large vein thromboses that are not suitable for thrombectomy or thrombolysis treatments. If a filter is placed under other conditions, it is very likely that thrombosis will re-form on the surface of the filter, potentially leading to some recurrent pulmonary embolisms or iatrogenic pulmonary embolisms. Therefore, the decision to place a filter is complex and requires a doctor to weigh the pros and cons before deciding whether or not to proceed.

What are the symptoms of a pulmonary embolism warning sign?

Pulmonary embolism is also very common in clinical settings, mainly seen in patients who have been bedridden for a long time, undergone various major surgeries, suffered from long bone fractures, pregnancy, etc. In the early stages of pulmonary embolism, patients generally experience varying degrees of chest pain, hemoptysis, and difficulty breathing, among others. If pulmonary embolism is suspected and the patient's condition permits, a pulmonary artery CTA scan should be immediately carried out to further confirm the diagnosis of pulmonary embolism. If the pulmonary embolism has already caused circulatory disturbances, thrombolytic therapy should then be considered.

The most common symptoms of pulmonary embolism.

Pulmonary embolism is also relatively common in clinical practice, primarily caused by an embolus blocking the pulmonary artery system, leading to a group of clinical syndromes. The clinical manifestations of pulmonary embolism mainly include the following points: The first is that patients may experience unexplained difficulty breathing and shortness of breath, especially after activity. The second is that patients experience significant chest pain. The third may be accompanied by hemoptysis, but usually, the amount of blood expectorated is not large. The fourth is that patients may experience restlessness, panic, and even a sense of impending doom. Clinically, there sometimes appears the so-called triad, which includes simultaneous occurrence of difficulty breathing, chest pain, and hemoptysis, etc. Pulmonary embolism is primarily diagnosed clinically through pulmonary artery CT.

How long does the treatment for pulmonary embolism take?

The timing of pulmonary embolism treatment mainly depends on the severity of the pulmonary embolism. The main goals of pulmonary embolism treatment are to save lives by addressing life-threatening right heart dysfunction and obstructive shock caused by the pulmonary embolism, to re-establish pulmonary vascular patency, restore lung tissue perfusion, and prevent the recurrence of pulmonary embolism. Main treatment methods include: respiratory and circulatory support, anticoagulation, thrombolysis, interventional or surgical removal of blood clots, placement of inferior vena cava filters, etc. General management: Patients who are highly suspected or diagnosed with pulmonary embolism should be closely monitored, tracking changes in respiration, heart rate, blood pressure, venous pressure, electrocardiogram, and blood gases to prevent the dislodgement of clots again. Absolute bed rest is required, and care should be taken not to overly bend the lower limbs, maintain bowel regularity, and avoid straining. For patients experiencing anxiety and panic symptoms, reassurance should be provided, along with appropriate use of sedatives. If there is chest pain, analgesics may be administered. For symptoms like fever and cough, corresponding symptomatic treatments should be given. To prevent lung infections and treat phlebitis, antibiotics may be used. Additionally, support treatments for respiratory and circulatory functions, as well as anticoagulation therapy, should be provided.
