Chapter 720

Director Jiang has performed hundreds of circulatory interventional surgeries, and has seen more surgeries. Some are made by themselves; some are wearing lead coats, standing behind the teacher watching; some are sitting in the operating room watching the screen.

But this is the first time Director Jiang has seen this kind of perspective lying on the operating table.

In the upper left of the field of view, there is a screen, and the image on the screen is still the angiography of the previous wounded person after thrombectomy. He knew that soon there would be movement there, and it was his coronary artery that appeared.

Whether it is anterior wall myocardial infarction or not, you can tell at a glance.

Not only that, he suddenly found himself able to observe Zheng Ren's surgery from the patient's point of view.

Just thinking of this, Director Jiang suddenly realized one thing - Dr. Zheng, will he do circulatory interventional surgery?

As this thought rose, the spirit that had just been relieved suddenly became tense, and there was a tingling pain in the front of my heart.

"Expanding the crown!" Zheng Ren said immediately when he saw that the ECG oscilloscope displayed on the ECG monitor began to become disordered.

The nurse with the station immediately began to inject medicine to Director Jiang.

"Old Jiang, can't you be more honest?" Su Yun was a little impatient.

Mainly because he is familiar with Director Jiang. Su Yun knows that the more casual he talks on stage, the more nervous he will be relieved. After all, he had never seen Zheng Ren perform cardiac interventional surgery. If he looked like he was on the verge of an enemy, the consequences would be serious.

Unexpectedly, it was an acute myocardial infarction.

"I...I'm not...I wonder if Dr. Zheng will do it." After the injection of the drug was completed, Director Jiang felt that the pain in the precordial area had improved.

"Lie down, if he can't, no one will." Su Yun said contemptuously, "Nobel Prize judge, Dr. Mayhal..."

"Don't talk about this, as soon as he gets excited, the blood vessels will spasm, and it will be even more troublesome if he attacks again." Zheng Ren said calmly.

"Promising!" Su Yun glanced at Director Jiang and scolded.

After a few words, local anesthesia, an arterial sheath, and a guide wire catheter were placed in the radial artery of the wrist.

Zheng Ren began to step on the line, and the contrast agent was perfused into Director Jiang's coronary artery.

Director Jiang looked sideways at the screen, feeling emotional, this speed is as fast as ever. Me too, what are you worried about?

What did Brother Yun say about the Nobel Prize? Maybe, Director Jiang stopped thinking about these messy things and let himself go by watching the screen.

But before he could let himself go, his thoughts were immediately interrupted by the angiography on the screen.

Angiography revealed a localized severe concentric stenosis of the proximal left anterior descending coronary artery with almost 100% stenosis and a lesion length of about 10-15 mm.

There was no obvious abnormality in the circumflex branch. The moderate concentric stenosis of the second segment of the right coronary artery was about 50%, and the length of the lesion was about 15 mm.

The judgment is correct, this diagnostic level is really awesome! Director Jiang admired it.

The ECG can give some hints, but it is still difficult to judge so accurately.

"Boss, you said that it has been almost 200 years since Bernard first inserted a catheter into an animal's heart in 1844. I feel that there is no breakthrough in cardiac interventional surgery." Su Yun looked at Director Jiang's angiography. The image, with completely different words on his lips.

"It shouldn't be calculated like this." Zheng Ren said while removing the angiography catheter: "If we start to calculate, I think it was in 1929 that the German doctor Forssmann first inserted a urinary catheter from his cubital vein through the superior vena cava. Into the right atrium can be said to be the beginning of cardiac interventional surgery."

While speaking, Zheng Ren had already sent the 7F JL4.0 guide catheter through the vascular sheath to the left coronary ostium, and first sent the 0.014" PTCA guide wire to the distal end of the anterior descending branch.

"Thromb removal catheter." Zheng Ren said.

Wearing a lead coat, he followed the incoming equipment nurse and handed over a catheter. Su Yun opened the outer packaging, "You said that within 20 years, robotic surgery can be performed, and there will be no other progress except that the thread will not be eaten. General surgery using the Da Vinci robot is just taking off your pants and farting.”

"It is enough to treat the disease. If it is to be solved fundamentally, chemistry and genetics must be studied." Zheng Ren put the thrombectomy catheter into the vicinity of Director Jiang's anterior descending branch.

Director Jiang felt that this was the atmosphere of the operating room.

The surgeon and the assistant were chatting, it was simple and easy, not everyone was busy doing surgery before, and countless wounded were waiting for treatment, and people who were under great pressure would collapse at any time.

Suddenly he felt as if his whole life was back on track.

It's just that now I'm a patient lying on the operating table, other than that, everything is normal.

Oh, and there is something abnormal, that is Zheng Ren's hand speed, which is simply too fast!

After the thrombectomy catheter went in, he didn't see him thinking, and even Director Jiang didn't feel anything. The thrombectomy catheter on the screen started to walk out with a black thing.

Is this done?

Director Jiang is so confused.

This kind of fresh emboli, if he takes it himself... His technical level is not up to the level, so he can only accommodate tube thrombolysis.

If you can take it, you should also add a filter, and be careful, for fear of breaking the fresh emboli and causing more unpredictable complications.

Where is Zheng Ren, who carelessly sent the thrombectomy catheter to the location, clamped the thrombus, and walked out.

"Doctor Zheng, what technique are you using here?" Director Jiang asked blankly, looking at the screen.

Fresh emboli are as tender as tofu, and it is extremely difficult to remove them completely.

So Director Jiang has such a question.

Zheng Ren smiled and said, "This is not the time to discuss. The earthquake relief is over. If you have time, you can come to the 912 hospital to find me."

Director Jiang nodded, this is Dr. Zheng's promise to go to 912 for further study once again.

Only this time, his mood changed.

Dr. Zheng, that's a real bull, but it's not pretending or blowing it out.

Soon, the image of the thrombectomy catheter disappeared, and Su Yun caught the fresh thrombus with a piece of sterile gauze.

On the white gauze, the purple-black emboli of about 1cm looked so hideous.

It was it just now, blocking the coronary artery and almost killing Director Jiang.

"Old Jiang, take a look." Su Yun stood up the gauze block on its side, and Zheng Ren was afraid that the embolus would fall off at any time.

But Su Yun is generally accurate in his hands, so there should be no problem.

"You're already like a bear, and you're still screaming for rescue there. You talk about you and delay things." Su Yun's temper was endless, and his way of speaking did not change.

Director Jiang rarely sees fresh blood clots. As for his own, this is really the first time.

He smiled. It turned out that it didn't hurt when the bolt was removed.

"Boss, you said that the anterior descending branch is 100% blocked, why doesn't he respond?" Su Yun asked.

"I'm too nervous, too much lactic acid has accumulated in the body, and I don't feel the pain clearly... um, it doesn't seem right." Zheng Ren said, but he couldn't continue.

These are not reasons, and Zheng Ren himself felt that it was far-fetched.

In fact, what he thought in his heart was that what supported Director Jiang was a whole lot of blood.
