Ten years ago, with cholecystitis, almost all of them cut a knife in the stomach, and then cut off the gallbladder; today, ten years later, only 3 holes in the stomach can be removed gallbladder; ten years ago, with pituitary tumors, you need to open a window of bone in the head, and then pulling open the brain tissue to remove the tumor; and today, only need to insert a mirror in the nostrils can be pulled out of the tumor; ten years ago, with ureteral calculi, it is necessary to stop the waist Ten years ago, if you had a ureteral stone, you would need to cut your waist to remove the stone, but nowadays, you can get it done by wound-free extracorporeal shock wave lithotripsy or ureteroscopy. These new methods are not only less painful, less traumatic, rapid recovery, and brain aneurysm, there are also minimally invasive methods? There is! It is a neurointerventional procedure in the endovascular category. The method is to puncture the femoral artery on one side, and then insert a catheter with an inner diameter of 2 millimeters into the carotid artery or vertebral artery through the aorta under the supervision of x-ray television. A very soft microcatheter with an inner diameter of 1 mm or thinner is then selectively fed into the aneurysm through the catheter, through which removable spring coils are filled into the aneurysm one by one to occlude it, thus achieving the same effect as craniotomy. The traditional treatment method is to saw open the patient’s skull first, dissect the natural gap of brain tissue under the microscope, and pull open the brain tissue to expose the aneurysm and clip it. Obviously, neuro-interventional therapy has the advantages of light damage, less pain and faster recovery. After the introduction of this method, it immediately set off a revolution in aneurysm treatment in developed countries in Europe and the United States. The vast majority of aneurysm patients choose interventional surgery rather than craniotomy. In Britain, France and other countries, there is almost no craniotomy for aneurysm treatment at all. Due to the relative economic backwardness of our country, there are not many units with endovascular intervention technology and equipment, and the consumables required for interventional therapy basically rely on imports. Therefore, at present, only a few large medical units can carry out, the proportion of interventional procedures in economically developed areas such as Beijing and Shanghai is higher than that in other areas, and in economically relatively backward and impoverished areas, craniotomy is still the mainstream. It is believed that in the near future, with the development of economy, the improvement of people’s cognitive level, the reduction of the cost of interventional therapy and the rapid development of new technology and new materials, the replacement of traditional craniotomy by interventional therapy will not be far away. This is the gospel of aneurysm patients.
