suddenly cooled down after the National Day work week, the first ward of the Cardiovascular Surgery Department of Xiangya Second Hospital of Central South University carried out 15 acute type A aortic dissection surgery through the aortic dissection green channel, setting a new record of the number of single-week aortic dissection surgery cases in the hospital, which is rare in domestic comprehensive hospitals. At present, all surgical patients have recovered well, and some patients have completed various postoperative re-examinations and are preparing to be discharged from the hospital.
aortic dissection green channel is coordinated by the Ministry of Medicine, and has been linked to multiple disciplines such as emergency medicine, surgery department, radiology department, laboratory department, anesthesiology department , and blood transfusion department. An efficient and standardized emergency treatment process has been established. Among them, the number of people who were admitted to acute A-type aortic dissection, which had the most dangerous condition, increased from 211 in 2016 to 309 in 2021, an increase of 46.4%, ranking first in in the central region of . While the number of admitted people and the number of surgeries have repeatedly hit new highs, the overall treatment rate of patients with aortic dissection has significantly increased, the mortality rate has been significantly reduced, the incidence of complications has gradually decreased, the average hospitalization day of has been greatly reduced, the patient's hospitalization cost has also decreased, and the patient's satisfaction has continued to increase. The patient's medical experience, happiness and gain have been significantly improved.
The aorta is the largest artery in the human body. The blood flow ejected from the heart first enters the aorta and then shunts it to each branch artery. The aortic wall is divided into three layers: inner membrane, middle membrane and outer membrane. The aortic dissection is caused by various pathological factors, such as hypertension , arteriosclerosis, congenital dysplasia, etc., causing the endometrium of the arterial wall to tear, and blood rushes from the rupture into the middle and outer membranes, forming a new outwardly protruding blood vessel lumen, called the "false lumen", while the original vascular lumen is called the "true lumen". There is only a thin layer of arterial outer membrane blocking the "false cavity". If the outer membrane cannot withstand the blood pressure in the body, the outer membrane will rupture, causing heavy bleeding, which is very likely to cause the patient to die. The aortic dissection is very dangerous and is called a "vascular bomb". Statistics show that if patients diagnosed with acute type A aortic dissection are not treated promptly after the onset of the disease, the mortality rate exceeds 50% within 48 hours.
The Department of Cardiovascular Surgery of Xiangya Second Hospital accepts more than 300 patients with type A aortic dissection every year, and the autumn and winter are at a high incidence period. One week after National Day this year, among the patients with aortic dissection admitted, 12 were typical of hypertension, and most of them did not pay attention to the stable control of blood pressure. The main causes of patients with aortic dissection include heavy work, emotional excitement, excessive force, and standing up while squatting. The symptoms of aortic dissection are sudden and severe tear-like chest pain, and some patients will experience shock. Professor Tang Hao, director of the ward of the first ward of the Cardiovascular Surgery Department of
, specifically reminded that patients with hypertension should control their blood pressure regularly and control their blood pressure heart rate within a normal range, especially in cold seasons, especially in winter and spring. Do a good job of keeping warm and not performing strenuous exercise. Once severe chest pain, back pain, abdominal pain and other discomforts occur, you must seek medical treatment in time to avoid adverse consequences.
