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.

Pulmonary Embolism Interventional Treatment Methods

Interventional treatment for pulmonary embolism is mainly used for large pulmonary embolisms in the main trunk or major branches of the pulmonary artery. It is applicable in the following scenarios: contraindications to thrombolysis and anticoagulation therapy, inefficacy after thrombolysis or aggressive medical treatment, or lack of surgical conditions. Interventional therapy for pulmonary embolism can involve removing the embolus or breaking it into fragments, allowing it to move to the distal pulmonary arteries, thereby opening the central pulmonary arteries, rapidly reducing pulmonary artery resistance, significantly increasing total pulmonary blood flow, improving cardiopulmonary hemodynamics, and right ventricular function. The treatment involves catheter fragmentation and suction of large clots in the pulmonary artery or performing balloon angioplasty, and it also enables local administration of small-dose thrombolysis. These are the primary methods of interventional treatment for pulmonary embolism.

Why does pulmonary embolism cause cardiac arrest?

The mechanisms causing cardiac arrest due to acute pulmonary embolism mainly encompass several aspects. One is a large-scale acute extensive pulmonary embolism, which prevents the blood from being ejected from the right heart, potentially leading to acute right heart failure. At this time, the entire body's blood circulation will encounter issues. Another scenario is that following the pulmonary embolism, it causes severe hypoxia. This hypoxia can lead to oxygen deficiency in all organs of the body, including the heart. The coronary arteries that supply nutrients to the heart can also become ischemic. Both of these factors can cause the heartbeat to lead to sudden cardiac arrest. These are the primary mechanisms that can cause a sudden stop in the heartbeat.

Pulmonary embolism belongs to which department?

Pulmonary embolism mainly refers to the detachment of thrombi in the blood, leading to the obstruction of the main trunk of the pulmonary artery and its branches, causing a series of syndromes. Pulmonary embolism is an emergency in clinical practice. If the patient's circulation becomes unstable after the embolism, thrombolytic therapy should be considered. If the patient's respiratory circulation remains stable after the embolism, anticoagulation therapy can be considered. In clinical practice, pulmonary embolism is primarily diagnosed through pulmonary artery CTA examination to further clarify the diagnosis, and patients generally consult the respiratory medicine department.

Early symptoms of pulmonary embolism

In the early stages of pulmonary embolism, symptoms such as difficulty breathing, chest tightness, shortness of breath, and decreased oxygen saturation can occur. Early signs may include chest pain, as chest pain is often an initial symptom of pulmonary embolism. Sometimes the pain can be severe, and some patients may experience coughing, dry cough, and even cough up blood. There may also be symptoms of short exhalation and difficulty breathing, especially in patients with main trunk blockages, where the difficulty in breathing can be very pronounced. In more severe cases, some may experience fainting, suddenly collapsing while walking.
