Feng Xiang: local repair of abdominal aortic aneurysm endovascular patients avoid general anesthesia risk health Sohu published: Feng Xiang deputy chief physician, associate professor, deputy director of the Department of general surgery of Changhai Hospital of Shanghai. Mr. Wang, 90, was lying on the operating table calmly, with a X- line monitor showing a abdominal aortic aneurysm with a diameter of about 7 cm in his abdominal aorta. In his groin, a catheter with memory alloy stent and ultrathin artificial vascular complex, through a 1 cm long incision from the femoral artery into his abdominal aorta, is scheduled to arrive at the site after the catheter slowly exit, memory alloy stent will slowly open, again showed abdominal aorta angiography of abdominal aortic aneurysm, his magic disappeared. The operation is only an hour ended, Mr. Wang had witnessed a "time bomb" torture him for 3 years by the doctor out of hand. Third days after surgery, Mr. Wang left the hospital on foot. It is the most advanced minimally invasive endovascular repair of abdominal aortic aneurysm in Changhai Hospital of Shanghai. Since March 1997 in Changhai Hospital since the country carried out the first endovascular repair of abdominal aortic aneurysm, technology progress, now the femoral artery cut open in minimally invasive repair and development can be performed under local anesthesia of the femoral artery puncture endovascular abdominal aortic aneurysm repair. Compared with minimally invasive endovascular repair and previous laparotomy, with reliable curative effect, simple operation, small trauma, fast postoperative recovery, completely solves the open surgical trauma, complex operation and complication rate and mortality rate high, so it is called the technological revolution of the abdominal aorta aneurysm treatment history, and puncture repair under local anesthesia to patients currently even general anesthesia but also to avoid the risk. In fact, Mr. Wang was diagnosed with abdominal aortic aneurysm has been 3 years, once around the doctor, but because he is frail, suffering from hypertension, coronary heart disease, diabetes and other diseases, the operation is too risky, the hospital refused to surgery is minimally invasive endovascular repair to enable him to obtain a cure the opportunity. In fact, abdominal aortic aneurysm should not be called "tumor", it is only the appearance of a "tumor", actually abdominal aortic pathological effects in local expansion of the bulge, and not in the usual sense of the tumors, so it is a benign disease. There are many causes of abdominal aortic aneurysm, the most common is hypertension and arteriosclerosis, other causes of trauma, infection, may also be congenital. The most common manifestations of abdominal aortic aneurysm is the upper abdomen or umbilicus pulsatile mass, sometimes there is pain or symptoms of oppression surrounding organs. After the formation of abdominal aortic aneurysm, under the impact of arterial blood flow, the fluid will gradually expand. According to the principle of physics, the greater the diameter of abdominal aortic aneurysm, the aneurysm wall pressure is larger, generally speaking, the probability of a ruptured aneurysm diameter greater than 5cm will be greatly increased, aneurysm rupture will cause the death of the patient because of massive bleeding, so the aortic aneurysm is referred to as "bomb patients".
