One by one, they stretched their necks like a flock of geese scrambling to get through the leaded glass to take a closer look. They were counting in their hearts how many items were similar to the interventional surgeries in their cardiovascular department, and how many were strange that they had never seen before.
Xie Wanying also looked up and seized the precious opportunity to study hard.
The surgeon took a Y-shaped valve and connected it to a tube. One end was connected to normal saline, and he was ready to inject heparin to heparinize the patient's whole body. This is a routine step in many interventional surgeries. Since the tube entering the femoral artery is under pressure, not an intravenous drip, the saline bag needs to be infused under pressure. The nurse took a pressure 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 two hands, which was too laborious and difficult to control the pressure.
During the pressurized infusion of fluids, nurses need to keep a close eye to prevent accidents.
Whether it is traditional open surgery or interventional surgery, examinations must be done before treatment and the lesions must be identified during surgery. Today's patient is even more special. No aneurysm was found in the CT scan report. The doctor could not determine whether there was a tumor or its specific location before surgery. He could not determine whether there was any disease in the blood vessels in the brain. What I told the patient and family members before the operation is that they must first perform a whole-brain angiography to fully examine the blood vessels in the brain to see if relevant lesions can be found.
Create shadow media and shoot in various positions.
What appears on the monitor screen is the angiographic image of the cerebral blood vessels.
This is the most interesting thing about interventional surgery. The angiography of different organs of the human body in different specialized departments can clearly show the different and wonderful blood vessel distribution patterns of each organ. Each has its own characteristics and can be said to be unique.
Like the pulmonary angiography mentioned last time, the blood vessels of the lungs are like a lush tree branching left and right. In cardiovascular angiography, the cardiovascular system looks more like a cluster of horizontal twigs. The images presented by cerebral angiography are very bizarre. Each image looks like an abstract art painting. It may be two flowers growing on a bare branch, it may be a strange mess of tangled threads, it may be A few individual branches give off a sense of isolation.
The cardiologists at the scene were completely silent. They were completely confused and could hardly tell the difference between east, west and north.
Knowledge from different fields of expertise is as separated as a mountain. Even if you have to see and learn from 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 time, and you need to accumulate clinical practice over time.
Cardiology doctors 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 and independent knowledge points in anatomy.
The only thing they can confirm now after seeing it with their own eyes is that the distribution of blood vessels in the brain should be much more difficult than that of their heart blood vessels.
The top of surgery, the nerves at the top of surgery, are not just random words. The distribution of cerebral blood vessels is too wide, and the images taken are too fragmented. It is too slow to integrate it and just rely on the machine to do 3D mapping. The only way is for the neurosurgeon's brain to spin crazily first.
You can imagine that a doctor who is a neurosurgeon must have the best brain among all doctors.
The operating room was quiet, and the control room was silent.
Neurosurgeons' eyes are like cameras, seriously putting the images into their minds for detailed review and calculation.
