Nine a.m.

Operating Room 3.

At this moment, Sun Xinxin was already lying on the hospital bed, Zhao Heng was under preoperative anesthesia, the chief surgeon was naturally Liu Ziang, and he also brought two resident doctors, the instrument nurse was Sun Li, and Tian Zhen was the itinerant nurse who cooperated with Zhao Heng.

The hospital attached great importance to this operation, and a discussion meeting was held before the operation.

At this seminar, different opinions were also put forward on what kind of surgery Sun Xinxin would take.

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

The first is clipping of the aneurysm neck, which is the most commonly used and most thorough method of cerebral aneurysm surgery. The doctor separates the aneurysm neck from the surrounding tissues and uses an aneurysm clip to clip the neck of the aneurysm.

The second method is intervention, that is, the treatment is carried out by vascular intervention, and the intracranial aneurysm is effectively tamponade with a yellow circle, so as to achieve the purpose of treatment.

In general, aneurysm clipping is definitely used, which is more thorough, but this method is very likely to cause permanent damage to brain tissue.

For Sun Xinxin, once this method is adopted, it means that she will never be able to continue to be an athlete in the future.

Therefore, after discussing with Liu Ziang, Zhao Heng decided to use the interventional method, that is, to use interventional embolization first, that is, to use high-resolution three-dimensional reconstruction of DSA and modification of elastic yellow circles, auxiliary balloons, special stents for intracranial aneurysm treatment and blood flow diversion devices to directly embolize the aneurysm and close the blood flow of the aneurysm.

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

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

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

The most important thing is that the location of the first surgery, that is, interventional embolization, must be extremely precise, otherwise, the second revision surgery will not be able to achieve the desired effect.

Therefore, this time the operation is actually quite difficult.

Just when Zhao Heng finished the anesthesia and sat next to him and waited for the anesthesia to take effect, Liu Ziang came to Zhao Heng's side and stood still, and said, "Senior brother, this embolization, I'm afraid I need your cooperation later." ”

No matter how good a doctor is, he can't perform an operation alone, especially for such a difficult brainstem aneurysm surgery.

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

"Hmm."

Zhao Heng nodded, and Liu Ziang had surgery together, he had to do anesthesia again, and at a critical time, he had to go to the stage for surgery, although it looked strange, but he was already very used to it.

"I work both anesthesia and surgery, and I work two jobs, should I receive two subsidies?"

Zhao Heng jokingly said to Liu Ziang again.

"I'm going to have a big dinner in the evening."

Liu Ziang smiled and said.

Hearing this, Zhao Heng was a little interested, and even a person like Liu Ziang, who could spend money to buy more than 10,000 coffee machines and put them in the office, said that it was a big meal, so he was still looking forward to it.

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

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

First of all, two people must cooperate to perform routine transfemoral artery puncture in the Seldinger method, insert the 6F catheter sheath and 6F catheter in turn, and send the catheter to the carotid artery on the affected side under the guidance of the real-time light catheter transmission.

This step, as simple as it is said, is nothing more than sending a catheter from the femoral artery to the carotid artery.

However, the location of this pathway is the main artery of the human body, as long as there is a little shaking, if the artery is damaged, this operation will not need to be done, and the consequences are even more unimaginable.

Crucially, this procedure 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 in.

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

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

Looking at the incomparably tacit cooperation between Zhao Heng and Liu Ziang, this scene is like an art performance.

At this time, Liu Ziang's brows furrowed slightly, and his movements stopped.

"Senior, what's wrong?"

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

"Look at the middle of the picture."

Liu Ziang said.

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

Because, in the middle of the electronic picture, near the carotid artery, he saw a small embolus attached to the carotid artery wall, and this embolus was still washing with the flow of blood, constantly shaking.

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

Once these conditions occur, the 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 work.

"Senior, use the Rotarex to suction the plug, I'll do it."

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

Zhao Heng's Rotarex thrombus aspiration system is a new type of guidewire-guided thrombus aspiration device, which is safe, fast and effective in thrombectomy.

It mainly uses a spiral-shaped cutter head that rotates at high speed in the side hole at the end of the catheter tip to generate negative pressure to suck thrombus and plaque into the side hole, which is crushed and withdrawn from the body by the rotating cutter head.

"With Rotarex, then you have to do it with one hand, can you?"

As soon as Zhao Heng's words came out, Liu Ziang also asked with some concern.

Zhao Heng is still doing fixed work, and if he removes the thrombus, he will have to do it with one hand.

This is not only a distraction, but also the requirement for stability is even more outrageous.

"I'm confident, senior, if you don't, it's too late."

Zhao Heng nodded and said with certainty.

The time of interventional treatment is limited, and the catheter stays in the artery, which can have a great impact on the arterial blood flow, and once the time is processed, there will be an unpredictable chain reaction.
