The patient underwent a pulmonary CTA examination at a secondary hospital in the province due to " pulmonary infection " and was diagnosed with large-scale pulmonary artery embolism. He was transferred to the Department of Peripheral Vascular Disease Intervention of our hospital one by one for emergency interventional surgery treatment.
According to Du Zizhong, director of the Department of Interventional Peripheral Vascular Disease, acute pulmonary embolism has the characteristics of high misdiagnosis rate, high mortality rate and high disability rate. The techniques of local pulmonary artery thrombolysis, thrombus fragmentation, and thrombectomy used in the surgery are very mature, but the risk of surgery is very high when the patient is confused and has difficulty breathing in a critical condition. The main concern is that the patient is in a state of long-term hypoxia, especially cardiopulmonary function damage. The heart may stop beating again at any time during the operation, which is a life-threatening risk. At the same time, the patient also has pulmonary infection, anemia, hypoalbuminemia and other factors, and the recovery during and after the operation is The situation is unpredictable. In addition, when the patient is restless, how to safely pass the catheter through the atrioventricular valve into the main pulmonary artery in the diastolic valve opening gap is also a big test. With the active cooperation of Director Du's team of medical staff at all levels, and after strenuous efforts to rescue the patient, the operation was successful and the patient was finally out of danger.
Pulmonary embolism is not far away
Pulmonary embolism is generally a thrombus in the venous system (mostly a thrombus in the lower limbs) that breaks off and flows back along the blood, reaches the right heart through the inferior vena cava, and then enters the blood vessels of the lungs. The pulmonary arteries are like tree root-like ends, and the blood vessels are getting thinner and thinner. If the emboli fall off into the pulmonary arteries, they will easily block the pulmonary blood vessels. Pulmonary embolism is one of the most dangerous emergencies. 70%-80% of patients with pulmonary embolism cannot reach the hospital for treatment after onset. Fundamentally, the lungs are the organs that supply oxygen to the whole body and discharge carbon dioxide , ensuring the exchange of inhaled oxygen and carbon dioxide in the blood. Once the pulmonary artery is blocked, there is no gas exchange, oxygen cannot be inhaled, carbon dioxide cannot be exhaled, and the blood vessels cannot be cleared immediately. All organs in the body will fail and die due to hypoxia, especially the brain's tolerance to hypoxia. The sex is the worst. Stopping breathing for more than 5 minutes will cause irreversible damage to the brain and eventually lead to disability or death.
