They stretched their necks like a flock of geese trying to get a closer look through the lead glass, counting in their minds how many of the objects were similar to the interventional surgeries in their cardiovascular department and how many were rare and had never been seen before.
Xie Wanying also looked up and seized the precious opportunity to study hard.
The surgeon took a Y-shaped valve and connected the tube, one end of which was connected to saline, ready to inject heparin to implement systemic heparinization of the patient, which is a routine step in many interventional surgeries. Since the tube enters the femoral artery with pressure, not intravenous drip, the saline bag connected needs to be pressurized for injection. The nurse took a pressurized bag and put it on the outside of the saline bag, and used an air bag to inflate and pressurize it, instead of the old method of squeezing and pressurizing with both hands, which is too laborious and difficult to control the pressure.
During the pressurized infusion, the nurse needs to keep his eyes open to prevent any accidents.
Whether it is a traditional open surgery or an interventional surgery, an examination must be done before treatment to identify the lesion during surgery. Today's patient is even more special. The CT scan report did not show an aneurysm. The doctor could not determine whether there was a tumor or the specific location of the tumor before the operation, and could not determine whether there was a lesion in the blood vessels in the brain. I also told the patient and his family before the operation that a whole brain angiography must be performed first to fully examine the blood vessels in the brain to see if the relevant lesions can be found.
Create contrast agent and take X-rays in various body positions.
The image that appears on the monitor screen is angiography of the cerebral blood vessels.
The most interesting thing about interventional surgery is this. Different specialist departments can clearly show the different and wonderful blood vessel distribution maps of different organs by performing angiography on different organs. Each has its own unique features.
As mentioned last time, the pulmonary angiography shows that the blood vessels of the lungs are like a lush tree with branches on the left and right. In cardiovascular angiography, the cardiovascular system is more like a cluster of small horizontal branches. The images presented by cerebral angiography are very bizarre. Each image looks a bit like an abstract art painting. It may be two flowers growing on a bare branch, a strange tangled thread, or a few branches showing a sense of loneliness.

The cardiologists at the scene were completely silent. They were so confused that they could hardly tell east from west.
Different specialties have different knowledge. Even if you learn about them in textbooks and internships as a medical student, if you really want to master the comprehensive knowledge of a specialty, you can't do it in a short internship period. You need clinical practice over a long period of time.
Cardiologists cannot infer the distribution of cerebral blood vessels from the distribution of coronary arteries in the heart. The two are completely different and independent knowledge points in anatomy.
The only thing they could confirm after seeing it with their own eyes was that the distribution map of cerebral blood vessels should be much more difficult than that of their heart vessels.
The pinnacle of surgery, the pinnacle of neurosurgery, is not an exaggeration. The distribution of cerebral blood vessels is too wide, and the images taken are too fragmented. It is too slow to integrate them by relying on machines to build 3D maps, so neurosurgeons can only think frantically.
It can be imagined that a neurosurgeon must have the best brain among all doctors.
The operating room was quiet and the control room was silent.
The neurosurgeons' eyes were like cameras, solemnly reviewing and calculating each image in detail in their minds.
