687 Signal Issues
In the live broadcast of the operation, the shape of the patient's brain appeared.
Macroscopic thickening of the arachnoid membrane, atrophy of the brain, and may be polycystic.
The patient's brain atrophy is extremely severe, and the gap between the brain and the skull in the skull on the operative side is very large, Huang Tianci estimates that if the patient has cerebral hemorrhage, there will be no autonomic symptoms within 100ml.
100ml is a conservative estimate, and 200-300ml will not be a problem.
Although the brain is atrophied as a whole, the temporal lobe is somewhat abnormally "developed", Huang Tianci couldn't figure out why, he asked in a low voice, "Old director, have you ever seen this situation?"
Director Zhai frowned and looked at the live broadcast screen, and shook his head slightly, "It is said that it should not only be so developed in the temporal lobe, it should be the same as the atrophy of other tissues." Could it be that Wu Mian's kid delayed the operation just now because he found that there was a problem with the temporal lobe?"
"Probably not, the preoperative video data was not sent, but I feel that Wu Mian and Chu Zhixi should have watched the film many times before the operation, and they know it in their hearts. Huang Tianci said, "In particular, the neuronavigation equipment to set the surgical approach must have been tempered." ”
Director Zhai nodded and continued to concentrate on the operation.
During the live broadcast, Chu Zhixi released cerebrospinal fluid during ventricular puncture in order to facilitate the operation, causing the brain on the affected side to further collapse.
Expose the lateral fissure, tear the arachnoid membrane, carefully retract the frontotemporal lobe, and examine it parasalamella.
The two tiny neurosurgical microforceps were free little by little, and the middle cerebral artery was gradually clearly exposed.
This step was done very cautiously by the surgeon Chu Zhixi and his assistant Wu Mian, the speed was not fast, and every small branch was exposed as much as possible to reduce secondary damage.
The screen is not like an operation, but a live view of a specimen of local anatomy. Chu Zhixi and Wu Mian's microscopic operations are very subtle, and every action is difficult to distinguish on the big screen.
Fortunately, the Jianxie Hospital was very well prepared, and at the moment of microscopic operation, two fields of vision were opened on the right side of the screen, and one was Wu Mian's microscopic field of view and the other was Chu Zhixi's microscopic field.
The scope of the surgery is only a millimeter, and there is nothing special about the free process, no matter who does it, it is the same free process. It's just that Chu Zhixi and Wu Mian cooperate tacitly, and there is no interference or influence on each other.
The internal carotid artery, the middle cerebral artery, the anterior cerebral artery, and their bifurcations appear little by little in the surgical field.
It wasn't until the distal end of the middle cerebral artery dividing the lenticular artery was double-clamped and cut off with a silver clip, and the distal end of the anterior cerebral artery branching out of the anterior communicating artery was clamped and cut off with a silver clip, that the doctors in the conference room breathed a sigh of relief.
It's good that there is no heavy bleeding, but if you are not careful here, and there is a slight mistake, a small branch blood vessel will be broken and bleeding, and the entire surgical field will become a red color, and nothing can be seen.
Hemorrhage has always been a major problem for neurosurgery.
Unlike thoracic and general surgery, as long as you don't catch up with extreme cases, no amount of blood will affect the surgical field. After all, it is no problem for the chest cavity to hold 3000ml of blood, and the volume of the abdominal cavity is larger.
The suction device is inserted, and the blood is sucked out. In this case, the surgeon does not consider the surgical field, but the patient's hemorrhagic shock.
However, the scope of neurosurgery is intracranial, and the atrophy of one side of the brain of the patient in front of him can only "hold" 2-300ml of blood.
The operation was really fine, and Huang Tianci sincerely sighed in his heart. He glanced at the time, and it took 42′22 to free the middle cerebral artery and the anterior cerebral artery.
The surgery is also very general, although it is delicate, but it is too slow...... Thinking about it, Huang Tianci suddenly fell into a trance.
He realized what he had forgotten.
From the beginning of the free until the distal artery was clamped with a silver clip, there was no bleeding at all!
The surgical area is extremely clean, there is not even a trace of blood, and it does not look like a neurosurgery at all!
Huang Tianci was familiar with the neurosurgery all the way carefully, but he didn't know which blood vessel was broken, and the blood that came out stained all the surgical fields red, and he couldn't see anything in the microsurgical field for an instant.
Alas, how important it is to have a good assistant, Huang Tianci sighed in his heart.
If he had an assistant of Wu Mian's level, he would definitely be able to achieve this level of finesse in the operation!
Sure!!
Sure...... Perhaps.
The operation continued, slowly but surely advancing.
After 22′, the surface of the cerebral cortex, which enters the drainage vein next to the sagittal sinus, that is, the superior cerebral vein, is separated, and subsequently cut off by bipolar electrocoagulation.
Next, it's time to lift the posterior part of the temporal lobe and free the labbé vein and the draining vein on its occipital lobe, Huang Tianci thought to himself.
Chu Zhixi and Wu Mian's operations were carried out step by step, like a textbook.
There is no sensationalism, from the beginning to the present, all the operations are simple and plain, plain and peaceful, not like watching a hemispherectomy that is beyond the sky.
Each step seems to give a hint to the person watching the surgery that it will be a success.
Huang Tianci knows that as long as the surgeon's energy consumption is too great because of the time of the operation, and the operation has been done at the current stable level, success is inevitable.
But herein lies the problem.
Can anyone concentrate for 12 hours, or even 15 hours? Impossible.
Maybe there will be a mistake in the next step, Huang Tianci looked at the video screen intently, and kept using his own experience to compare the surgical process of Chu Zhixi and Wu Mian.
A hand wearing a white sterile glove lifted the back of the patient's temporal lobe, but at that moment, the live signal began to flash.
Like the old TV in the eighties of the last century, the signal is not good, and the signal receiver has to be adjusted. The jutsu field on the screen began to distort, and a faint sound came from the stereo.
What's going on? Even if there is a problem with the network signal transmission, it is a lag, it is a delay, and it will not be like it is now.
Huang Tianci looked at the picture suspiciously.
Fortunately, the screen was not distorted for a long time, and after about 20", the screen signal returned to normal.
Huang Tianci didn't care, after all, it was a remote transmission, and no matter which link went wrong, it would lead to an abnormal situation. I'm just a doctor, not a network engineer, so I can't figure it out.
But the hand in the operating room seemed to sense something, and instead of immobilizing the patient's temporal lobe with a retainer, he slowly shifted another direction.
There was another problem with the signal transmission, and the noise was distracting.
Can the movement of the temporal lobe affect the network signal? Huang Tianci was a little puzzled.
But when the signal improved, the posterior part of the patient's temporal lobe had been fixed, and Chu Zhixi and Wu Mian began to free the Labbé vein and the draining vein on the occipital lobe.
The scene just now seemed to be just an illusion of Huang Tianci, and it didn't exist at all.
