Blood clots in the lungs usually refer to pulmonary embolism. Whether pulmonary thrombosis can be cured is related to the patient’s physical condition, the degree of embolism, etc. Generally, mild pulmonary embolism can be cured. Pulmonary embolism refers to a group of clinical syndromes caused by emboli blocking the pulmonary artery and its branches, including thromboembolism, fat embolism, amniotic fluid embolism, air embolism, etc., of which pulmonary thromboembolism (i.e., pulmonary embolism) is the most common. Patients with mild pulmonary embolism can usually be cured with medication (e.g. pethidine, dopamine, etc.), thrombolytic therapy (e.g. urokinase, etc.), and anticoagulant therapy (e.g. heparin, warfarin, etc.). The patient is advised to reduce activities and take more bed rest to avoid re-dislodging of thrombus. Severe pulmonary embolism can only relieve the symptoms caused by pulmonary embolism after the above treatment, and it is difficult to be cured. Surgery can be given if necessary, but surgical treatment is risky and should be chosen carefully according to the specific condition. If the diagnosis of pulmonary thrombosis is confirmed, it is recommended to carry out standardized treatment as early as possible in order to reduce the adverse effects of the disease. All of the above medications should be used under the guidance of a doctor, avoid self-medication.
