  Xie Wanying looked at her head and seized the precious opportunity to study hard.

  The surgeon took a Y-shaped valve, connected a tube, one end was connected to saline, and was ready to inject heparin to implement heparinization of the patient\'s whole body, which is a routine procedure for many interventional operations. Since the tube enters the femoral artery under pressure, not an intravenous drip, the connected saline bag needs to be injected under pressure. The nurse took a pressurized bag over the saline bag, and used a balloon to inflate and pressurize, instead of the old way of squeezing and pressurizing with both hands, which was too laborious and difficult to control the pressure.

   During pressurized infusion of fluids, nurses need to keep an eye on them to prevent accidents.

  Whether it is traditional open surgery or interventional surgery, an examination must be done before treatment to determine the lesion during surgery. Today this patient is even more special. There is no aneurysm in the CT scan report. The doctor cannot determine whether there is an aneurysm or the specific location of the aneurysm before the operation, and it is impossible to determine whether the blood vessels in the brain have lesions. What I said to the patients and their families before the operation is that a whole-brain angiography must be performed first, and the blood vessels in the brain must be thoroughly checked to see if relevant lesions can be found.

   Create a contrast agent and shoot in various positions.

   The angiography image of the cerebral blood vessels appears on the monitor screen.

This is the most interesting point of    interventional surgery. The imaging and imaging of different organs of the human body by different specialist departments can clearly show the different and wonderful blood vessel distribution diagrams of each organ, and each has its own characteristics and can be called unique.

  Like the pulmonary angiography mentioned last time, the blood vessels in the lungs are like branches of a lush tree left and right. Cardiovascular angiography, cardiovascular more like a cluster of lateral twigs. The images presented by cerebral angiography are very bizarre. Each image is like an abstract art painting. It may be two flowers growing on a bare branch, or it may be a strange mess of twine, or it may be A few branches alone give a sense of loneliness.

  The cardiologists at the scene were completely silent, they were completely dizzy, and they could not tell the difference between east, west, north and west.

  Different specialized knowledge is interlaced like mountains. Even if the medical students had to see and study in textbooks and internships, but in the end, if you really want to grasp the comprehensive knowledge of a specialist, you can\'t do it in a short internship time, and you need to accumulate clinical practice over time.

   Cardiologists cannot infer the distribution of cerebral blood vessels from the distribution of blood vessels in the coronary system of the heart. The two are completely different independent knowledge points in anatomy.

  The only thing they can confirm after seeing it with their own eyes is that the cerebral vascular distribution map should be much more difficult than their cardiovascular blood vessels.

   The top of surgery, outside the nerves of the top of surgery, is not blown away. The cerebral blood vessels are too widely distributed, and the images taken are too fragmented. To integrate it, it is too slow to rely on the machine to do 3D mapping by itself. It can only be that the brain of the neurosurgeon is going crazy first.

   You can imagine a doctor who is a neurosurgeon. This brain must be the best brain of all doctors.

  The operating room is quiet, and the control room is quiet.

   Neurosurgeons look like cameras, seriously putting images scene by scene into their minds for detailed review and calculation.
