Mr. Wang, 90, lay calmly on the operating table while an X-ray monitor showed a 7-cm diameter abdominal aortic aneurysm in his abdominal aorta. In his groin, a catheter with a memory alloy stent and an ultra-thin artificial vascular composite was introduced into his abdominal aorta from the femoral artery through a small 1cm-long incision, and after reaching the intended site, the catheter slowly withdrew and the memory alloy stent slowly opened up. The surgery was over in just over an hour, and Mr. Wang was fortunate enough to witness a “time bomb” that had been tormenting him for three years being removed by the surgeon’s hands. On the third day after the surgery, Mr. Wang was discharged on foot. Feng Xiang, Department of Vascular Surgery, Shanghai Changhai Hospital This is a scene of the Department of Vascular Surgery of Shanghai Changhai Hospital treating abdominal aortic aneurysm with the most advanced minimally invasive endoluminal repair procedure in the world. Since Changhai Hospital was the first in China to carry out endoluminal repair for abdominal aortic aneurysm in March 1997, the technology has continued to advance and now the minimally invasive femoral artery dissection endoluminal repair has been developed into femoral artery puncture endoluminal repair for abdominal aortic aneurysm that can be performed under local anesthesia. Minimally invasive endoluminal repair has the characteristics of reliable efficacy, simple operation, small trauma and fast postoperative recovery compared with previous open surgery, which completely solved the shortcomings of previous open surgery with large trauma, complicated operation and high complication rate and mortality, thus it is called a technical revolution in the history of abdominal aortic aneurysm treatment, and the technique of puncture repair under local anesthesia makes the patient avoid even the risk of general anesthesia at present. In fact, Mr. Wang had been diagnosed with abdominal aortic aneurysm for 3 years and had sought medical help everywhere, but because he was old and frail and also suffered from various diseases such as hypertension, coronary heart disease and diabetes, the risk of surgery was too great and all major hospitals refused to operate on him, and it was the minimally invasive nature of endoluminal repair that gave him a chance to be cured. Abdominal aortic aneurysm should not be called “aneurysm”, it only looks like “aneurysm”, but is actually a local expansion of the abdominal aorta under pathological action, and is not a tumor in the usual sense, so it is a benign disease. There are many causes of abdominal aortic aneurysms, the most common being hypertension and atherosclerosis, while other causes include trauma, infection, and possibly congenital. The most common presentation of abdominal aortic aneurysm is a pulsating mass in the upper abdomen or around the umbilicus, sometimes with vague pain or compression of surrounding organs. After the formation of abdominal aortic aneurysm, the fluid will gradually expand and enlarge under the impact of arterial blood flow. According to physics, the larger the diameter of an abdominal aortic aneurysm, the greater the pressure on its wall. The greatest physicist of the 20th century, Albert Einstein, left the world of space and time that he led us to understand again because of a ruptured abdominal aortic aneurysm, and Professor Li Siguang, a famous geologist in China, also died because of a ruptured abdominal aortic aneurysm. Ruptured abdominal aortic aneurysms currently account for the tenth leading cause of death from disease in adult males in the United States, and the incidence of aortic aneurysms is rapidly increasing in China as our population ages and dietary structure changes. Surgical treatment of abdominal aortic aneurysms has been attempted by surgeons since the 18th century, but until the advent of artificial blood vessels in the 1950s, many of the surgical methods tried failed to achieve a complete cure for abdominal aortic aneurysms, and patients often died from ruptured abdominal aortic aneurysms even after receiving treatment, the most vivid example of which was Albert Einstein, who underwent an abdominal aortic aneurysm wrap in 1948 and died tragically from a ruptured abdominal aortic aneurysm in 1955. He unfortunately died of a ruptured abdominal aortic aneurysm in 1955. After the mid-1950s, the advent of artificial vessels made abdominal aortic aneurysm resection with artificial vessel replacement the classic treatment for abdominal aortic aneurysms. The procedure involves complete dissection of the abdominal aortic aneurysm under general anesthesia, blocking the aorta at both ends of the aneurysm, ligating the branch arteries of the aneurysm and then removing the aneurysm and anastomosing the artificial vessel to the dissected ends of the arteries at both ends of the aneurysm, which is very traumatic and the blockage of the aorta has a direct impact on important organs such as the heart, brain, lungs and kidneys, and the incidence of complications of organ failure after surgery is high. This surgery requires patients to have more sound internal organ function to withstand the blow of such a major surgery, but unfortunately, the average age of onset of abdominal aortic aneurysm is around 70 years old, and most of these patients have different coexisting diseases such as hypertension, coronary heart disease, diabetes, and pulmonary and renal decompensation, which makes the surgery much more dangerous, and many patients lose the chance to be cured because they cannot tolerate the surgery, and this contradiction is in the abdominal aortic aneurysm This paradox has plagued vascular surgeons and patients with abdominal aortic aneurysms for more than 40 years since the introduction of resection and prosthetic vessel replacement, often putting physicians and patients in a dilemma. This embarrassing situation in the surgical treatment of abdominal aortic aneurysms was fundamentally changed after the 1990s with the advent of endoluminal repair. It is worth mentioning that in addition to abdominal aortic aneurysms, minimally invasive endoluminal repair can also be used for the treatment of thoracic aortic aneurysms, thoracic aortic pseudoaneurysms, carotid aneurysms, etc.
