Chapter 732: 721 A Heart Full of Hot Blood

Director Jiang has performed several hundred to over a thousand circulatory interventional surgeries, and has seen even more surgeries. Some he performed himself; some he watched wearing lead clothing while standing behind the teacher; some he sat in the control room watching the screen.

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

In the upper left of his field of view is the screen; the image on the screen is still the angiography from the previous patient's thrombectomy. He knows it will soon change, showing the condition of his own coronary arteries.

Whether it's an anterior wall myocardial infarction can be told at a glance.

Moreover, he suddenly realized he could observe Director Zheng's surgery from the patient's perspective.

Just as he thought this, Director Jiang suddenly realized—would Doctor Zheng be able to perform circulatory interventional surgery?

As this thought arose, his recently relaxed spirit suddenly tensed, and a sharp pain came from his precordial area.

"Dilate the coronary!" Zheng Ren said immediately upon seeing the ECG waveform on the monitor begin to become chaotic.

The instrument nurse promptly started administering medication to Director Jiang.

"Old Jiang, can't you just be honest?" Su Yun said, somewhat impatient.

Mainly because she was familiar with Director Jiang, Su Yun knew that speaking casually on the table would greatly ease his tension. After all, he had never seen Zheng Ren perform cardiac interventional surgery; if he acted like facing a formidable enemy, the consequences could be serious.

But unexpectedly, he still suffered an acute massive myocardial infarction.

"I... I'm not... just wondering if Doctor Zheng will be able to do it." As the medication injection finished, Director Jiang felt the precordial pain ease somewhat.

"Just lie still; if he can't do it, nobody can." Su Yun said contemptuously, "Nobel Prize committee, Dr. Mei Ha'er..."

"Don't say that; if he gets excited, his vessels will spasm, and another episode would be even more troublesome." Zheng Ren said calmly.

"What a prospect!" Su Yun glanced at Director Jiang and rebuked.

In the time it took to exchange a few words, local anesthesia at the wrist radial artery, arterial sheath placement, and guidewire and catheter insertion were completed.

Zheng Ren began threading the wire, injecting contrast agent into Director Jiang's coronary arteries.

Director Jiang turned his head to look at the screen, feeling moved; this speed, as always, is fast. As for himself, what is he worried about?

Yun Ge'er mentioned the Nobel Prize, perhaps; Director Jiang stopped thinking about all those miscellaneous things, staring at the screen and blanking his mind.

But before he could blank his mind, his train of thought was immediately interrupted by the angiography on the screen.

The angiography revealed a limited, severe concentric stenosis in the proximal left anterior descending coronary artery, nearly 100% stenotic, with a lesion length of about 10–15 mm.

The circumflex branch showed no significant abnormality; the second segment of the right coronary artery had a moderate concentric stenosis of about 50%, with a lesion length of about 15 mm.

The diagnosis is correct—this diagnostic level is truly awesome! Director Jiang admired it in his heart.

The ECG can give some hints, but making such an accurate judgment is still difficult.

"Boss, you said from when Bernard first inserted a catheter into an animal's heart in 1844 until now, it's almost two hundred years; I feel there hasn't been any breakthrough progress in cardiac interventional surgery." Su Yun looked at Director Jiang's angiography image, saying something completely different.

"That's not how it should be calculated." Zheng Ren said while removing the angiography catheter: "If we start counting, I believe it began in 1929, when German doctor Forssmann first inserted a urinary catheter from his own elbow vein into the right atrium via the superior vena cava, which can be considered the start of cardiac interventional surgery."

In the time it took to speak, Zheng Ren had already sent a 7FJL4.0 guide catheter through the vascular sheath to the ostium of the left coronary artery, then advanced a 0.014-inch PTCA guidewire to the distal LAD.

"Thrombectomy catheter." Zheng Ren said.

Wearing lead clothing, the instrument nurse who followed him in handed over a catheter; Su Yun opened the outer packaging, saying, "You said that within twenty years we could launch robotic surgery, but aside from not eating sutures, there's really no other progress. Using the Da Vinci robot for thoracic and general surgery is pure nonsense."

"As long as it can treat the disease, that's enough; if we truly wanted to solve it at the root, we'd need to study biochemistry and genetics." Zheng Ren sent the thrombectomy catheter near Director Jiang's LAD.

Director Jiang felt, this is the atmosphere of the operating room.

The surgeon and assistant chatted casually, simple and relaxed, unlike before when everyone was silently focused on surgery, with countless casualties awaiting treatment, the pressure making people ready to collapse at any moment.

Suddenly he felt as if his whole life had returned to the right track.

Except that now he himself is the patient lying on the operating table; otherwise, everything is normal.

Oh, and there is something abnormal: Zheng Ren's hand speed is incredibly fast!

After the thrombectomy catheter went in, he didn't seem to think about anything; Director Jiang even felt nothing, as the screen showed the thrombectomy catheter carrying a dark object beginning to move outward.

Is that it?

Director Jiang was quite bewildered.

For such a fresh clot, if he were to remove it himself... his technical skill falls short; he could only use catheter-based thrombolysis.

Assuming it could be retrieved, one would also need to add a filter, proceeding with extreme caution, fearing that touching the fresh clot would shatter it, causing more unpredictable complications.

Unlike Zheng Ren, who nonchalantly positions the thrombectomy catheter, grasps the clot, and pulls it outward.

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

A fresh clot is as soft as tofu; to extract it intact is extremely difficult.

Thus Director Jiang had this question.

Zheng Ren smiled and said, "Now is not the time to discuss; after the earthquake relief ends, if you have time, come find me at Hospital 912."

Director Jiang nodded; this was Doctor Zheng once again promising him further training at Hospital 912.

But this time, his mood had somewhat changed.

Doctor Zheng, he's truly impressive—not just putting on a show or bragging.

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

On the white gauze, a purple-black clot about one centimeter in size appeared so menacing.

Just now it was that, blocking the coronary artery, nearly costing Director Jiang his life.

"Old Jiang, take a look." Su Yun stood the gauze piece upright; Zheng Ren feared the clot might fall off at any moment.

But Su Yun usually has a steady hand; there should be no problem.

"You're in such a state, yet you're still shouting and carrying on with the rescue; you're just delaying things." Su Yun's temper knows no bounds, and her manner of speaking hasn't changed.

Director Jiang rarely sees fresh thrombi; as for his own, this is truly the first time.

He smiled; it turned out that thrombectomy doesn't hurt.

"Boss, you said the LAD is 100% blocked; how could he have no reaction?" Su Yun asked.

"He's too tense; his body has built up too much lactate, making pain perception less noticeable... uh, actually that might not be right." Zheng Ren said, trailing off.

These aren't reasons; saying them out, Zheng Ren himself also feels it's far-fetched.

Actually what he was thinking was that what supported Director Jiang was a heart full of hot blood.
