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 a pulmonary embolism be detected by a CT scan?

CT can detect acute pulmonary embolism, using CT angiography, which is the preferred imaging method for diagnosing pulmonary embolisms. It mainly shows central filling defects, as well as eccentric and abdominal wall filling defects, and complete filling defects. A diagnosis of pulmonary embolism can be made through the visualization of these filling defects on a CT scan. Additionally, some indirect signs, such as pulmonary hypertension, right ventricular enlargement, and the common mosaic sign, can also be observed. These are characteristic CT manifestations of acute pulmonary embolism.

Is pulmonary embolism related to pneumonia?

If unexplained shortness of breath, pleuritic chest pain, tachycardia, and decreased oxygen saturation occur, one should be highly vigilant about pulmonary embolism. Generally, pulmonary embolism has no direct relationship with pneumonia. High-risk factors for pulmonary embolism include obesity, prolonged immobilization, stroke, congestive heart failure, malignant tumor, inflammatory bowel disease, lower limb fracture, anesthesia time exceeding 30 minutes, and acquired or genetic hypercoagulable state. It usually manifests as difficulty breathing, rapid breathing, and pleuritic chest pain.

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.

The difference between pulmonary embolism and pulmonary congestion

Pulmonary embolism and pulmonary congestion are two completely different diseases. Pulmonary embolism is mainly caused by the thrombosis of the venous vessels entering the pulmonary artery, thereby causing restricted blood flow in the pulmonary artery and leading to pulmonary embolism. Pulmonary congestion is often due to left heart failure, where the blood flow in the lungs cannot return to the left heart, causing the blood to be retained and congested in the lungs, forming this disease. However, they do have some similarities, such as presenting symptoms of difficulty breathing, shortness of breath, low blood pressure, shock, etc. But through diagnosis and additional examinations, these two diseases can be clearly differentiated. Therefore, careful differentiation is required in clinical practice because the treatments for the two diseases are completely different. If misdiagnosed, the treatment could be incorrect, leading to serious consequences from mistreatment.

Can I eat lamb if I have pulmonary embolism?

Patients with pulmonary embolism can appropriately eat mutton, as it is acceptable in their case. For pulmonary embolism, it is advocated to follow a light diet, avoiding spicy, irritating food, and excessively greasy food to prevent aggravating the gastrointestinal burden of the patient. Additionally, it is acceptable for patients with pulmonary embolism to consume some meat, as long as it is not fatty meat. Once diagnosed with pulmonary embolism, patients should receive active treatment, which often requires anticoagulant therapy. If the condition is not too severe, simple anticoagulant treatment may allow the patient’s condition to recover. However, if the pulmonary embolism is more severe, thrombolytic therapy may be necessary. After thrombolytic treatment, vascular anticoagulant therapy is given to manage the patient's condition.
