Chapter 243: 0237 The Surgery Is Rough (1/5)

Su Yun, note this position. Zheng Ren pointed to a branch of the superior vesical artery and said to Su Yun, who had been standing behind him.

Su Yun held a pen and paper, recording the position Zheng Ren mentioned.

The recorded text was neither Chinese nor English, but some special symbols that only he could understand.

Although he used the simplest symbols to record, an A4 sheet was already filled up, and it looked like he would need another page soon.

And he had already filled three sheets of similar paper.

"How is it? Any progress?" Su Yun noticed Zheng Ren's expression change slightly, seemed like a breakthrough, and asked.

"We should try it. If we had a finer microguidewire, the effect would be great; under the current conditions, we can completely follow what we said before and try using the neurology department's interventional guidewire to open the tiny branch artery."

In the neurology department's interventional surgery, the microguidewire has the smallest diameter, making it finer and harder to control.

Even so, it still cannot meet the needs of prostate interventional surgery.

But under the current conditions, we can only do this.

After exchanging a few words, they each went back to being busy.

Zheng Ren was still doing the reconstruction, occasionally telling Su Yun to record a certain position. The recorded anatomical locations were scattered, with no regularity at all.

Su Yun stood seriously behind Zheng Ren, for ten hours almost motionless. At this moment, Su Yun was the perfect assistant.

At 4:12 a. m., after completing the capillary network of the last blood vessel branch, Zheng Ren let out a breath, and a long‑absent smile appeared on his face.

"Done?"

"Almost. Next we'll test our two skill levels." Zheng Ren pointed at the screen and said: "The six major blood vessels branch out, then develop into a capillary network that supplies the prostate."

"Are you confident?" Su Yun didn't think Zheng Ren could do it; those fine, dense capillary networks would require super‑selective embolization, which is beyond current technical capability.

"Not at all." Zheng Ren spoke frankly.

Producing the 64‑slice CT three‑dimensional reconstruction was only the first step. It was like a wartime military map, merely letting him know what to do next.

The rest…… Zheng Ren calculated his remaining surgical training time and experience points.

Should he splurge? It seemed the time to splurge had come.

There seemed to be one or two golden treasure chests; could he have good luck? This thought just popped up, but Zheng Ren tossed it to the clouds.

As for relying on luck, it's better not to think about it.

A few hours earlier, after Zheng Ren created the capillary network for the first branch artery, he preliminarily worked out a surgical plan.

Because the vessels are too thin, a procedure similar to Lin JiaoJiao opening the ocular artery is needed—forcing a microguidewire through a vessel narrower than the guidewire itself, without exceeding the vessel's compliance, which would cause secondary bleeding from the manipulation.

Such an unconventional operation is rarely attempted; even when tried, it mostly ends in failure. If Zheng Ren hadn't once succeeded in opening Lin JiaoJiao's ocular artery, Su Yun and Director Kong would likely scoff at this surgical plan.

But even with that successful precedent, the two still weren't optimistic about the plan.

Performing the surgery this way is very difficult, but after discussion, the weakness of the domestic microguidewire in a specific period actually turned into an advantage.

The domestic microguidewire is relatively stiff, making its operation difficulty coefficient one level higher than that of imported guidewires.

A slightly stiffer guidewire is a drawback in ordinary surgery, but before Zheng Ren's "opening procedure," the drawback becomes an advantage. With a little care, the theoretical chance of success greatly increases.

So Director Kong went to inform Feng Xu Hui that they wanted to use their guidewires.

Saying this to Feng Xu Hui, it's uncertain whether he could keep the fruits of his victory.

Director Kong also meant well; seeing Feng Xu Hui following Zheng Ren closely these days, he did a sincere favor, letting Feng Xu Hui notify the higher‑ups of Longwind Micro‑creation to come and talk with him.

Zheng Ren neither knew nor wanted to know about these matters.

His entire spirit was immersed in the conception of the surgery, unable to extricate himself.

If the surgery isn't done well, doing a lot of other things is useless; Zheng Ren understands this principle.

"Take a rest." Zheng Ren woke Director Kong, who had been deeply asleep in the chair, and said softly.

"Go back to the Intervention Department, I'll nap a bit. If you still have energy, watch the surgery video of Professor Rudolf Wagner from Heidelberg University and see if there's anything worth learning from." Director Kong said.

Zheng Ren nodded.

For a body under thirty, pulling an all‑night is nothing special. Especially for clinical doctors and the inpatient chief of the Emergency Department, staying up late is a necessary skill. And as the senior chiefs grow older, their skill tree for staying up keeps withering.

This is an inevitable trend of human physiology.

Several people walked out of the CT room; Feng Xu Hui wasn't waiting outside this time, presumably gone to the airport to pick up his family's big boss.

Arriving at the teaching room of the Intervention Department, Director Kong opened the video, already extremely drowsy, he yawned and went to his office for a quick nap.

Who knows what else might happen today; being able to rest a bit is a rest.

Zheng Renze and Su Yun watched Professor Rudolf Wagner's surgery recording together.

Just like when other professors watched the recording the previous night, the skilled technique together with the handy microguidewire and microcatheter built a surgery that could be called perfect.

Su Yun felt a sigh inside, somewhat helpless.

To him, who is already familiar with interventional surgery, Professor Rudolf Wagner's operation is slightly stronger than Zheng Ren's, and with the handy microguidewire and microcatheter, this surgery can be said to be beyond Zheng Ren's current ability to surpass.

To surpass, it's actually not difficult.

Zheng Ren is still under thirty; at most five years… no, maybe three years will suffice, Zheng Ren's level will surely surpass Professor Rudolf Wagner's.

But saying this now means the failure of this research.

Whether success or failure, Su Yun doesn't care about the consequences; he just feels the burning fire of his strong competitive spirit, and without overcoming Professor Rudolf Wagner's great mountain, his spirit feels uneasy.

The surgery went very smoothly; after removing the pre‑ and post‑operative procedures, Professor Rudolf Wagner completed the entire prostate embolization process in a little over an hour.

Almost perfect.

"Boss, what do you think?" Su Yun glanced at Zheng Ren, who was fully focused on watching the video playback, reverted to his previous sharp‑tongued manner, and asked teasingly.

"The surgery was done very crudely." Zheng Ren said.

"……" Su Yun hadn't expected Zheng Ren to answer like that; in an instant he was stunned, looking at Zheng Ren as if he were a monstrous outsider.

This guy, does he still have a bit of conscience inside?
