Ms. Li became a mother, after a week in bed, she could get out of bed, only after two steps, she suddenly fainted, her family brought her to the first hospital, but no lesion was found in neurology and cardiovascular medicine, the experienced doctors considered respiratory diseases, and after a series of examinations, the cause of fainting was finally diagnosed by pulmonary arteriography as pulmonary embolism, and she was out of danger only after active thrombolytic anticoagulation treatment. The patient was rescued only after aggressive thrombolytic and anticoagulant treatment. Due to various reasons, deep vein thrombosis and dislodgement occur in human body, and the dislodged embolus blocks the pulmonary artery and its branches with blood flow through the right heart, causing the patient’s pulmonary circulation and respiratory dysfunction. According to the data, deep vein thrombosis occurs mostly in stroke patients, hip replacement patients, and pregnant women. In addition, people over 40 years old, obese, hyperlipidemia, trauma or surgery, long-term bed rest or braking, and malignant tumor are the high incidence of deep vein thrombosis, which is also the high incidence of pulmonary embolism. The clinical symptoms of pulmonary embolism are diverse and can be manifested as dyspnea, shortness of breath, chest pain, syncope, hemoptysis, cough, palpitation, irritability, panic and even near-death feeling, and different cases often have different combinations of symptoms, and the severity of the symptoms manifested in each case also varies greatly. Pulmonary embolism The diagnosis of suspected pulmonary embolism is confirmed by spiral CT pulmonary angiography or DSA pulmonary angiography, and the patient’s condition is evaluated to select thrombolytic and anticoagulant therapy. Thrombolytic therapy can rapidly dissolve the thrombus and reduce the death rate and recurrence rate of patients with severe pulmonary embolism, either systemic intravenous drug or selective pulmonary artery thrombolysis under DSA. Anticoagulation is the basic treatment for pulmonary embolism, which can prevent the re-formation and recurrence of thrombus, while the body’s own fibrinolytic mechanism dissolves the formed thrombus. For mild to moderate patients, our hospital often uses simple anticoagulation, which is safer and more economical. Our hospital has accumulated rich experience in the diagnosis and treatment of pulmonary embolism, and doctors in the emergency room also tighten the string of pulmonary embolism when they receive treatment, and promptly ask respiratory doctors for early diagnosis and correct treatment, and the cure rate is over 90%.
