The abdominal aorta is one of the most important blood vessels in the human body and is responsible for the blood supply to most of our internal organs such as liver, spleen, kidneys, bladder, intestines and both lower limbs, so the blood flow in the abdominal aorta is high. It is not a tumor but a dilatation of the lumen of the abdominal aorta, like a thinning and bulging part of a bicycle tire. As the diameter of the abdominal aortic aneurysm increases, the arterial wall will become thinner and thinner, eventually leading to rupture. Once ruptured, a large amount of blood will flow from the rupture, and the loss of blood will soon become life-threatening, so the abdominal aortic aneurysm is called an “untimely bomb” in the human body. In December 1947, Einstein was found to have an abdominal aortic aneurysm by chance during surgery for a gastric ulcer, and at that time the medical level in 1947 could not cure the abdominal aortic aneurysm. He was admitted to Princeton Hospital, where doctors diagnosed him with “ruptured abdominal aortic aneurysm” and pointed out that the only way to save him was to operate. He died at the age of 76. After his death, an autopsy of the abdomen by a specialist revealed a large amount of blood in the retroperitoneum, which was confirmed to be a ruptured abdominal aortic aneurysm. On November 29, 1977, Mr. Wu Youxun, a famous Chinese physicist, felt unwell, and at eight o’clock the next morning, Wu Youxun suddenly felt a stabbing pain at the root of his thigh, followed by panic, dizziness, dizziness, and instantly turned pale, unable to speak a word. She found that her father’s pulse was gradually weakening, and not long after, the pupils began to spread, and Wu Xiru had sensed that this was a symptom of acute hemorrhage in the body. As a doctor, Wu Xiru, although not a vascular surgeon but a pediatrician, had also initially concluded that the arterial vascular rupture in the thigh near the abdomen had poured blood into the abdominal cavity, and it was too late to save him anyway. When the ambulance arrived the only thing the doctors could do was to try to make a final diagnosis: ruptured abdominal aortic aneurysm haemorrhage. Coincidentally, Wu Youxun’s old friend, the famous geologist Li Siguang, had the same disease and had also died in 1971 from a ruptured abdominal aortic aneurysm. Mr. Wu Youxun died at 10:50 a.m. in less than three hours from the time he had obvious symptoms. Can abdominal aortic aneurysms be detected normally? Because abdominal aortic aneurysms grow deep in the body, they are usually asymptomatic and difficult to detect unless there are serious symptoms, such as rupture. In fact, with the current medical level, abdominal aortic aneurysms can be easily detected with an ultrasound examination. Therefore, for middle-aged and elderly people with high-risk factors, such as hypertension, coronary heart disease, cerebrovascular disease, etc., an ultrasound examination of the abdominal aorta is recommended when performing a physical examination. Einstein lived at a time when the technology for treating abdominal aortic aneurysms was still very immature. Nowadays, there is a minimally invasive method to treat abdominal aortic aneurysm, which is much simpler, more effective and safer than surgical incision, and that is the endoluminal isolation of abdominal aortic aneurysm. After releasing the stent, the memory alloy stent automatically opens up against the wall and both ends are supported on the normal abdominal aortic wall at the upper and lower ends of the aneurysm, allowing blood flow to pass directly through the artificial vascular membrane and isolating the abdominal aortic aneurysm. Isolation. This prevents further enlargement or even rupture of the abdominal aortic aneurysm because there is no further blood flow into the aneurysm. Compared with traditional open surgery, this type of intracavitary isolation of abdominal aortic aneurysm does not require general anesthesia, opening and blocking of the aorta, but only a small incision near the femoral artery, which is very minimally invasive. Minimally invasive surgery. If this method had been available, Einstein would not have died of an abdominal aortic aneurysm.
