Chapter 733: 722 You Should Rest

He thought that, but Zheng Ren's hand movements didn't pause at all.

After the thrombectomy catheter was withdrawn, he sent the guidewire to the vicinity of the stenosis in the second segment of the right coronary artery. Then, following the guidewire, he advanced a 2.5mm×20mm Crosssail balloon catheter to the stenotic lesion in the left anterior descending artery, inflated the balloon to 6–8 atmospheres for 5–8 seconds, and dilated the stenotic lesion.

"Is there a drug-eluting stent?" Zheng Ren suddenly thought of this question and asked.

At this moment, placing a drug-eluting stent in Director Jiang's coronary artery is the best choice.

Zheng Ren's vascular interventional surgery was practiced in the special care ward of the Karolinska Institute in Stockholm, Sweden, when he was preparing to operate on Dr. Mei Ha'er.

According to the external environment, the system, this Big Pig Trotter, equipped Zheng Ren with all the necessary supplies.

But the problem is that I am now at Pengxi Township Hospital, which is just a rural township hospital in the country.

For a hospital of this level, having an interventional surgery suite is already quite good; Zheng Ren thought it impossible to have drug-eluting stents.

Sure enough, the instrument nurse immediately said, "Doctor Zheng, there are no drug-eluting stents."

"What is there?"

"Only Boston Scientific's Express stent."

"Open." Zheng Ren looked at the screen and began to plan the procedure.

Soon, Su Yun had everything ready.

Zheng Ren immediately delivered the 2.75mm×12mm Express stent to the lesion, inflating the stent balloon to 6–12 atmospheres to expand the stent.

Repeat angiography showed antegrade flow distal to the lesion reaching TIMI III grade.

Zheng Ren expressed satisfaction with the surgical outcome and smiled slightly.

"Director Jiang, you have experience with postoperative medication, right? Without a drug-eluting stent, remember to take your medicine regularly." Zheng Ren asked.

Director Jiang was dumbfounded.

I can't do thrombectomy, but the speed of stent deployment is too fast. The position is standard, the stenotic segment is fully covered, there are no flaws, and nothing can be faulted.

Among the difficulties, Director Jiang has performed this surgery hundreds or thousands of times, but his skill is not particularly high; he knows this very clearly.

Due to lack of talent, Director Jiang's level has become difficult to improve.

Where exactly is the bottleneck? Director Jiang knows it's his insufficient three‑dimensional understanding of the images, plus a problem with his technique.

As the old saying goes, it's like feeling a heart through the belly skin.

That's not the literal meaning; it means that imaging findings and the actual situation can differ, and this currently has no solution.

At least for Director Jiang, it's an unsolvable problem.

The observed position differs somewhat from the actual position, and the amount of force applied also varies.

Watching Doctor Zheng's operation looks simple, but Director Jiang knows that if he were to deploy the stent and inflate the balloon, he either couldn't fully cover the plaque.

Or the process of expanding the stent could likely cause a tear in the severely atherosclerotic arterial intima.

It's not just possible; the likelihood is high.

In coronary heart disease patients, the vessels are inherently hard and brittle; if a force is applied to the intima and not controlled well, the intima will definitely tear.

But looking at the images, after Doctor Zheng placed the stent, there was not a trace of contrast agent residue.

This means there is absolutely no intimal tear or similar problem.

This feel, this skill—truly impressive!

Director Jiang lay on the operating table, watching the angiography process, and gradually became entranced.

Zheng Ren also saw for the first time a patient so intently watching the images here, which gave him a strange feeling.

He smiled, withdrew the guidewire and catheter, and applied local pressure.

"Director Jiang, don't go to the ward; just get an IV in the duty room." Zheng Ren said.

Director Jiang was still staring blankly at the angiographic images, not hearing Zheng Ren's words.

"Hey, Old Jiang! Wake up, step down!" Su Yun pushed Director Jiang.

"Huh? What's wrong?" Director Jiang came to his senses.

"You're really eager to learn." Su Yun laughed: "Both coronary arteries are fully open. Go back and take some medicine—I won't say what. Rest well lately; you don't need to worry about this side."

"I..." Director Jiang hesitated.

"Not worry? How could that be possible!"

How will we handle the wounded arriving steadily from the front? We've just reached the peak, and how can I not endure?

Countless negative emotions were about to coalesce, when Su Yun immediately said, "Old Jiang, cut it out! I'm telling you, your situation is barely okay—don't court death."

"..." Director Jiang felt helpless.

"You act as if the world would end without you." Su Yun scolded: "Even my boss wouldn't dare say that; what big garlic are you trying to show off?"

"Then what about this side..."

"Isn't there still Uncle Ning?" Su Yun said: "Uncle Ning works diligently and won't run himself into a heart attack like you."

Such harsh truths, coming from Su Yun's mouth, carry no burden.

"..." Director Jiang was speechless again.

"Uncle Ning is reasonable; rest assured, we're here on this side." Su Yun said, her tone shifting slightly: "I really envy you—being able to go home and sleep in. Boss, when are you planning to take a break?"

"As soon as we're done, hurry up and take him down, then bring up the next patient." Zheng Ren expressed his dissatisfaction with Su Yun using his blunt language.

How is this guy getting more and more naggy?

Zheng Ren is very tired, especially tired. If it weren't for the lead clothing that converts X‑ray radiation into "energy," plus the energy potion provided by the system, this Big Pig Trotter, Zheng Ren could not have persisted to now.

Nevertheless, even so, Zheng Ren has reached his limit.

He felt that the site of his left chest wall rib fracture was especially painful, and Zheng Ren even began to suspect he might also have a myocardial infarction, merely masked by the rib fracture pain.

The Big Pig Trotter is still not considerate enough; I can't even see my own system panel.

If I could see it, the system panel would probably be a pale red.

A rib fracture isn't a serious injury, and those bruises are nothing much. But could I have a myocardial infarction?

The more he thought this way, Zheng Ren felt increasingly chest tight and short of breath, with radiating pain in his shoulders and back……

Typical delusional disorder, Zheng Ren quickly dismissed all thoughts, stepped back a few steps, leaned against the wall, and took a moment to rest while they were moving Director Chiang.

Just a few Minute, but for Zheng Ren, it was also precious.

Director Chiang didn't leave the front line despite serious injury; even if he wanted to persist, nobody would agree.

Xie Ning arrived later, devoted part of his energy, and began to oversee the overall situation of the Interventional surgery Operating Room.

Everything continued, not stopping because Director Chiang left.

The Operating Room was brightly lit, one wounded after another was lifted onto the Operating table Shou Bing, then sent to various hospitals in Rongcheng, orderly.

The only difference was that Director Chiang lay in the Zhibanshi, snoring loudly.

He could finally sleep soundly; he couldn't not sleep.
