Recently a special patient came to the ward – Lao Xu, a native of Shanghai, more than 60 years old, usually smoking, drinking a little wine, there has been no major problems, and from the surface look completely normal, but also very healthy, can not see the appearance of disease. Maybe he thought so before coming to the hospital, but what happened in the past few days really made him break out in a cold sweat, according to his words is “from the ghost of the gate to walk. In the end, what disease is so serious? The original a few days ago, the old Xu urine inadvertently found blood in the urine, as people are also quite vigilant, fear of any serious illness to go to the local hospital physical examination again, blood in the urine is not a big problem, but found an unexpected result, the physical examination of the abdominal ultrasound found abdominal aortic dilatation, and then checked the abdominal aortic CTA, suggesting a huge abdominal aortic aneurysm on the verge of rupture, the maximum diameter of the aneurysm 212.5px. As a knowledgeable person, he could see on the film: the upper part of the artery continued normally to the lower part, like a ball dilated open, such results do not need to tell the doctor, but also really scared old Xu ah! You know, the normal adult abdominal aorta internal diameter of about 1.8-47.5px, Lao Xu this expansion of more than four times ah, so that the arterial wall thickness from the original 2-3mm to paper as thin ah, we all know that the artery all the time with high pressure, high-speed impact on the vessel wall, imagine, once the aneurysm rupture, the consequences are unimaginable which. Fortunately, Lao Xu’s unintentional act detected the time bomb hidden in his body in time, and under the active intervention and treatment of all the medical and nursing staff of vascular surgery, the bomb was successfully defused and a life was successfully saved. I believe not only Lao Xu, but also many people would like to know what abdominal aortic aneurysm is. In fact, abdominal aortic aneurysm mainly occurs in older people over 60 years old, related to atherosclerosis, hypertension, long-term smoking damage to the quality of blood vessels, mainly refers to the expansion of the whole layer of the abdominal aorta expansion, after the occurrence of long-term impact with blood flow can gradually increase, as a balloon, its harm is mainly manifested in three aspects: compression of surrounding tissues, causing turbulence to form thrombus off, expansion rupture. However, since patients with abdominal aortic aneurysms are usually clinically asymptomatic, many patients are discovered unintentionally or are detected only after the onset of symptoms, which makes diagnosis and education about the disease very difficult, as Donel, president of the Austrian Society of Physicians, said: “At present, the diagnosis of abdominal aortic aneurysms in Austria is mostly arbitrary. Some experts estimate that about six out of seven patients with abdominal aortic aneurysms are not treated correctly.” The situation in China is not believed to be good either. The diagnosis of abdominal aortic aneurysm is not difficult at present, with the help of ultrasound, CT, arteriography, DSA, etc. The main purpose is to prevent the rupture of the aortic aneurysm, which is directly related to the size of the diameter of the aneurysm. Some studies have shown that the incidence of rupture is 10% when the diameter of the aneurysm is less than 4 cm, and 30% to 50% when the diameter of the aneurysm is greater than 5 cm and less than 10 cm. If the diameter of the tumor is larger than 1O cm, the incidence of rupture is 80%. Therefore, a tumor with a diameter of 5 cm is currently used as a uniform clinical standard for performing surgical treatment. However, even if the aneurysm is small, there is a risk of acute rupture. Therefore, patients with abdominal aortic aneurysms should still undergo surgery as early as possible. Patients with small aneurysms should have regular imaging examinations (e.g., ultrasound), and if there is a tendency for the aneurysm to increase in size, surgery should be performed to prevent serious consequences. In the current national situation, it is urgent to popularize knowledge about abdominal aortic aneurysm and do a good job of primary prevention, then in our daily life, we should pay attention to the prevention of atherosclerosis, prolong the life of blood vessels, ensure the quality of blood vessels, and prevent the occurrence of aneurysm; secondly, control blood pressure, reduce the impact damage of blood vessels, prevent arterial flow while reducing the occurrence of thrombosis; finally, regular physical examination, check the body Health condition, strive to maintain the best state, only in this way, we can timely detection of the disease, and timely defuse this time bomb.
