Doctor: I picked up attributes in the hospital

Chapter 211 Surgery - Encountering Arterial Embolism!

The next day.

nine in the morning.

Operating room No. [-].

At this moment, Sun Xinxin was already lying on the hospital bed, and Zhao Heng was undergoing preoperative anesthesia. The chief surgeon, of course, was Liu Ziang, and he was accompanied by two residents. .

This time, the hospital attached great importance to the operation. Before the operation, an expert discussion meeting was held.

At this discussion meeting, there were also different opinions on what kind of surgery Sun Xinxin should adopt.

In general, there are two main surgical methods for brain aneurysms.

One is the clipping of the neck of the aneurysm, which is the most commonly used and most thorough method of cerebral aneurysm surgery.The doctor will separate the neck of the aneurysm from the surrounding tissue, and then use aneurysm clips to clip the neck of the aneurysm.

The second method is the interventional method, that is, the treatment is performed by means of vascular intervention, and the intracranial aneurysm is effectively packed with coils, so as to achieve the purpose of treatment.

For normal patients, clipping of the aneurysm must be used, which is more thorough, but this method is very likely to cause permanent damage to the brain tissue.

For Sun Xinxin, once this method is adopted, it means that she will no longer be able to continue to be an athlete in the future.

Therefore, after discussing with Liu Ziang, Zhao Heng and Liu Ziang decided to use the interventional method, that is, to use interventional embolization first, that is, to use high-resolution [-]D reconstruction DSA and modified coils, auxiliary balloons, special stents for intracranial aneurysm treatment and blood flow. A guide device that directly embolizes the aneurysm, shutting off blood flow to the aneurysm.

The aneurysm loses its blood supply, and it will naturally shrink slowly, and then to a certain extent, a complete resection is performed to repair the part of the artery wall occupied by the aneurysm.

Only in this way can Sun Xinxin have the hope of continuing to be an athlete.

However, although this is the best way for Sun Xinxin, for the chief surgeon, this is equivalent to increasing the complexity of the operation, which is equivalent to dividing one operation into two.

The most important thing is that the location of the first operation, that is, interventional embolization, must be selected extremely accurately, otherwise, the second repair operation will not be able to achieve the expected results.

Therefore, this operation is actually quite difficult.

Just when Zhao Heng finished the anesthesia and was sitting beside him waiting for the anesthesia to take effect, Liu Ziang came to Zhao Heng's side and stood still, and said, "Student, this embolization operation will probably require your cooperation later."

No matter how powerful a doctor is, he cannot complete a single operation, especially such a difficult brainstem aneurysm operation.

And in order to achieve the best effect, the position of the embolism must be precise, so there must be no error at all. In this case, even Liu Ziang needs the cooperation of a master like Zhao Heng.

"Ah."

Zhao Heng nodded, he was undergoing surgery with Liu Ziang, he had to be anesthetized, and at a critical moment, he had to perform surgery on stage again, although it seemed strange, but he was already used to it.

"I do anesthesia and surgery, and I work two jobs. Should I receive two subsidies?"

Zhao Heng said to Liu Ziang jokingly again.

"I invite you to dinner tonight."

Liu Ziang said with a smile.

Hearing this, Zhao Heng became a little interested. Even Liu Ziang, who can spend more than 1 coffee machines in his office, said it was a big meal, so he was looking forward to it.

After a while, the anesthesia took effect and the operation officially began.

At the beginning of the operation, Zhao Heng stood on the operating table. He had to follow the intracranial artery embolization from beginning to end.

First of all, two people must cooperate to carry out the conventional transfemoral artery puncture by Seldinger method, insert the 6F catheter sheath and 6F guide tube in sequence, and send the catheter into the carotid artery of the affected side under the guidance of the real-time light catheter transmission screen.

This step is simple to say, nothing more than sending a guiding tube from the femoral artery to the carotid artery.

But the location of this pathway is the main artery of the human body. As long as there is a little trembling and the artery is damaged, this operation is unnecessary, and the consequences are even more unimaginable.

The most important thing is that this operation must be performed by two people at the same time, one person is responsible for fixing, and the other person is responsible for feeding the catheter.

And Zhao Heng is naturally the one who is responsible for fixing it, because to a certain extent, a fixed position is one that cannot be moved at all.

This also shows that Zhao Heng's hands are actually more stable than Liu Ziang's, which is why Liu Ziang asked Zhao Heng to cooperate.

Looking at Zhao Heng and Liu Ziang's incomparable cooperation, this scene was almost like an art performance.

At this moment, Liu Ziang frowned slightly, and his movements stopped.

"Senior, what's the matter?"

Seeing that Liu Ziang's movements stopped, Zhao Heng asked with some doubts.

"Look at the middle of the picture."

Liu Ziang said.

Hearing Liu Ziang's words, Zhao Heng looked up, and his expression suddenly became serious.

Because, in the middle of the electronic screen, close to the carotid artery, he saw a small embolus attached to the wall of the carotid artery. This embolus was still swaying with the flow of blood.

Although it is a small embolus, if it is washed away by the blood flow, it will enter the blood circulation. If it blocks the lungs, it is a pulmonary embolism. If it blocks the heart vessels and cerebral vessels, it is a heart embolism and cerebral embolism.

Once these conditions occur, surgery can no longer be performed.

Moreover, now that the catheter has finally entered the carotid artery, if the catheter is withdrawn and re-entered, it will be a waste of all previous efforts.

"Senior, use the Rotarex suction plug, I will operate it."

Time waits for no one, Zhao Heng thought for a while and said to Liu Ziang.

The Rotarex thrombus aspiration system that Zhao Heng said is a new type of guide wire-guided thrombus rotary cutting device, which is safe, fast and effective in thrombectomy.

It mainly uses the high-speed rotating helical cutter head in the side hole of the catheter head to generate negative pressure to suck the thrombus and plaque into the side hole, crush it by the rotating cutter head and extract it out of the body.

"If you use Rotarex, then you have to operate it with one hand, can it work?"

As soon as Zhao Heng said this, Liu Ziang also asked with some concern.

Zhao Heng is still doing a regular job now, if he wants to remove the bolt again, he has to do it with one hand.

This is not only a dual-use distraction, but also requires an extremely high level of stability.

"I have confidence, senior, otherwise, the time will be too late."

Zhao Heng nodded and said with certainty.

The time of interventional therapy is limited, and the stay of the catheter in the artery will have a great impact on the arterial blood flow. Once time passes, an unpredictable chain reaction will occur.
