Zheng Ren seemed to hear the professor's prayer. The guide wire on the screen moved forward slowly but firmly, without any hesitation or pause, as it passed through.
Robin's eyes were as wide as eggs, but he didn't notice. Although his research direction is epidemiology, his professional quality is higher than 95% of circulatory interventionalists in the world.
Robin knew how difficult this level of surgery was.
Even if it was unclear, the final consultation opinions of experts from major European medical centers and the Karolinska Institute of Medicine and Surgery in Stockholm were there.
A disease that cannot be treated at all!
This is a disease that cannot be treated at all!
Rudolf Wagner, as stupid as a bull in heat, asked two young men to operate on the doctor.
This is absolutely ridiculous.
What's even more ridiculous is that they succeeded in the first step.
Robin was stunned as he watched the guide wire penetrate the "sighing wall".
The most difficult step has just been taken? He knew that as the completely occluded right coronary artery was opened, even just a little, Dr. Mehar's heart would be supplied with fresh blood.
Before that, the power that kept his heart beating came from the capillary network. How can that little arterial blood satisfy the beating of the heart
If it weren't for extracorporeal membrane lung, Professor Mehar would have gone to hell long ago.
The process of opening a blocked blood vessel is the most difficult and dangerous.
The fragile heart could stop beating at any time. On the operating table, the assistant next to the surgeon did nothing. He was posing there and preparing to defibrillate Dr. Mehar as soon as possible.
But he didn't move until a passage was opened.
The surgeon's operation was gentle, so gentle that he didn't even feel the heart that would collapse at the slightest exertion.
This is impossible! Robin looked at the screen in astonishment, his whole body stiff.
It's okay, it's okay, this is just the beginning. Robin comforted himself that before this, he had a full understanding of Dr. Mehar's condition and surgery.
Under such circumstances, no one could use rotational atherectomy to resolve the mountain of thrombus and calcification lesions in the doctor's coronary arteries.
Absolutely not!
Otherwise, the opinions of many experts across Europe and even the United States would not be so pessimistic after consultation.
No one recommended interventional surgery.
because,
No one can do it.
The guide wire was gently withdrawn, and then the rotational atherectomy probe was inserted.
The air in the entire operating room solidified, and everyone felt like there was a big stone pressing on their chest, making breathing a luxury.
The first step was successfully completed, which exceeded the expectations of all experts present. And the next step, who knows.
Professor Rudolf Wagner said that this young man had hands that had been kissed by God.
Looking at it now, it is indeed the case.
The action of just opening the right coronary artery was impeccable in every detail, perfect to the extreme.
But this is a routine operation to open blood clots. Many doctors have done it, but they have never done it as severe as Dr. Mehar's.
Next, the coronary rotational atherectomy will begin.
Dr. Mehar has all the contraindications for rotational atherectomy.
In the acute phase of thrombotic coronary artery disease or coronary heart disease, rotational atherectomy can aggravate the formation of thrombosis in the acute phase.
Moreover, Dr. Mehar's coronary angle has exceeded 90°, which is an absolute contraindication.
The large angle means that the space for rotational atherectomy during surgery is small, and the coronary artery may be leaked by rotational atherectomy at any time, causing coronary bleeding and pericardial tamponade.
Even if there is no leakage, if the intima of the blood vessel is ruptured by rotational abrasion, it will cause arterial dissection.
The people present, including the little doctors who recorded the values, were all the elites among the elites of their age. Everyone knows how difficult the operation is, and everyone's eyes are focused on the screen.
The rotational atherectomy head was sent into the right coronary artery without any attempts. The surgeon was extremely confident and went directly to the position and started rotational atherectomy.
Countless debris could be seen faintly appearing, but it was just vague because the speed was too fast and no one could see it clearly.
The debris is caught by the filter behind the rotational atherectomy probe, and larger debris is prevented from entering the coronary capillaries.
Tiny debris is harmless to the human body and will not cause embolism or necrosis.
Pieces of blood clots were cut and abraded away, turning into debris. Like drilling through a mountain to open a path, the rotary grinding probe moves forward, grinding out a passage of life.
The whole process is divided into two steps. The first step is what the surgeon is doing, which is simply polishing and rotary grinding to create a passage.
This step is so difficult that countless high-level professors dare not do it.
However, this is not the hardest part.
The most difficult step is the second step, which is to remove the thromboembolism and calcifications in the right coronary artery close to the vascular intima.
The staff at the Karolinska Institutet in Stockholm held their breath and watched the rotational atherectomy probe move forward step by step. In a few minutes, the access to the right coronary artery was basically opened.
Professor Rudolf Wagner did not relax, but became even more nervous.
The operation reached this stage, which was beyond his expectation.
However, the most difficult step is to rotate the area close to the intima of the blood vessel. It can be said that here, as long as the error of Zheng Ren's hand is less than 1mm, the operation can be declared a failure and Dr. Mehar can be declared clinically dead.
His palms were full of sweat, and the professor was staring at the screen intently, watching as the rotational atherectomy probe began to contact the intima of the blood vessel.
He subconsciously wiped his hands on his spotless white clothes to wipe away the sweat on his palms, but he could not wipe away the tension and anxiety deep in his heart.
Professor Rudolf Wagner's heart was beating very hard, as if there was a person beating a drum in his body. He was concentrating on watching the screen, but his body was shaking slightly with the strong heartbeat.
Robin, like Professor Rudolf Wagner, stared nervously at the screen. Because he breathed with his mouth open for a long time, he felt his mouth was dry. He swallowed hard, but felt a little pain.
Because of being too nervous, the oral glands have not secreted saliva for a long time.
Dehydrated mucous membranes rub together, causing damage, causing capillaries to rupture. For a moment, Robin felt the taste of blood in his mouth.
But he didn't pay attention to the changes in his body. Instead, he focused on looking at the screen, wrapping his fingers around his hands, pressing his nails tightly on the back of his hands, and his nail beds were pale.
The operation of the rotational atherectomy probe is precise to the millimeter level. The thrombus and calcified plaque adhering to the intima of the blood vessel are very finely rotated away, and the right coronary artery gradually takes on the shape that a blood vessel should have.
Half an hour later, Dr. Mehar, who was lying in the operating room, was in no problem at all. The expected fatal complications such as ventricular fibrillation, which was highly likely to occur, did not appear.
And with the opening of the right coronary artery, the blood supply to the myocardium improved, and the situation got better little by little.
It took half an hour for Zheng Ren to open the entire right coronary artery.
The moment he withdrew the rotary grinding probe, Su Yun let out a long breath.
"Boss, you scared me to death."
