Chapter 241: with translation of chapter title

"Manager Feng, what's wrong?" Zheng Ren asked.

"Chief Zheng... I, I... did I make a mistake?" Feng Xu Hui asked hesitantly.

"Where did I make a mistake? What's wrong?" Zheng Ren regained his previous clueless expression and asked, bewildered.

Su Yun looked at Zheng Ren with contempt, an expression that said you were just pretending to be naive.

"At noon..."

"Oh oh, that thing." Zheng Ren suddenly realized, "I have a few words to say with Su Yun; it's not convenient for you to follow. It's fine, it's fine."

Feng Xu Hui wouldn't believe it, his face grim. But he didn't dare say more, following Zheng Ren and Su Yun all the way to the Intervention Department.

After meeting with Director Kong, Doctor Shen stayed by his side, and everyone went all the way to the Urology Department.

The patient is 87 years old, with severe heart disease; after the coronary stent, the anterior descending branch remains 70% blocked, with occasional premature atrial contractions. Lung ventilation function is relatively poor, and coagulation function is also not good because oral warfarin is required after the stent procedure.

One could say this elderly gentleman has relatively severe surgical contraindications.

Even just removing the prostate carries the risk of the patient suffering a sudden heart attack and dying on the operating table.

But if the prostate isn't removed, it has already enlarged to a certain degree, causing urinary difficulty or even inability to urinate, requiring long-term catheterization—or, as for bladder surgery, the Urology Department would have to perform it despite the risk of death.

In other words, although the old man doesn't have a terminal illness, his basic quality of life has been lost.

The patient's sons are also in their sixties; three or four old men gathered together look like a retired officials' bureau holding a meeting.

After being informed of the old man's condition, the family members who were more agreeable consented to the experimental surgery.

The success or failure of the surgery is still uncertain, but at least it offers some hope—better than long-term catheterization, which causes inconvenience, urinary tract infections, severe cases can lead to retrograde urinary tract infection and abdominal complications.

After examining the patient, as expected, the surgical technique must be very gentle.

Zheng Ren had already prepared himself mentally, so he didn't say anything and simply took the patient to do a retrograde reconstruction with the 64-slice CT, also calling Qin Liren to join.

After all that, it was also time to get off work.

Zheng Ren happened to be free, so he did the 3D reconstruction himself, then looked for the capillary vessels on the prostate that had thickened like hairs after hyperplasia.

This difficulty is far greater than finding the feeding vessels of liver cancer.

Director Kong kept sitting beside Zheng Ren, watching him operate, feeling moved as he watched.

Previously, we thought Zheng Ren specialized in the liver, which is why his retrograde 64-slice CT three-dimensional reconstruction looked so beautiful.

But who would have thought—Zheng Ren seems to be more familiar with the prostate's anatomical structure.

You say you're a general surgeon, why are you so familiar with prostate anatomy? Although Director Kong had long been accustomed to the surprises brought by Zheng Ren and Su Yun's surgical partnership, seeing this scene still made his glasses shatter to the floor.

The prostate's 3D reconstruction is harder than the liver's because its vascular network consists of capillaries, which a regular CT cannot show at all; even with 3D reconstruction, one must choose a specific contrast phase to properly capture the capillary image.

Just as they were engrossed in watching, Director Kong's phone rang.

"Hello, it's me." Director Kong was a bit impatient, but upon hearing the next sentence, he immediately stood up.

"I'll be right there."

"Director Kong, what's wrong?" Zheng Ren asked while skillfully operating the retrograde 3D imaging.

"Nothing, just an emergency—keep doing your work." Director Kong's words were somewhat harsh and hoarse.

After saying that, he turned and left the CT Shi.

"Did you hear that clearly?" Zheng Ren asked.

"I didn't hear it clearly, but I guess the German professor's surgery over in Modu is probably finished." Su Yun said.

"Hmm." Zheng Ren continued working.

"Is there still any meaning to it?"

"I don't know, but we have to do something—otherwise what will happen to this patient? Should we invite the German professor again?" Zheng Ren wasn't discouraged; instead, he kept pressing forward against the indescribable difficulty.

……

……

In the institute's meeting room.

Wu Haishi, Wu Lao, Professor Pei and others arrived one after another; Li Haitao frowned with worry, and when Director Kong arrived, they were about to play the surgery video.

"Little Li, is it really true?" Director Kong still held a sliver of hope.

"Director Kong, the surgery over there officially ended at 4:15 p. m." Li Haitao said: "Please have a seat; let's assess whether there's still a need to continue this surgery."

Director Kong's expression was grave; he picked a seat near the front and sat down.

He didn't ask where the video came from; if they couldn't even get hold of that surgery footage, everyone present could collectively jump off a building.

"Hello everyone, let me introduce again. At 2 p. m. today in a certain hospital in Modu, Professor Rudolf Wagner of Heidelberg University in Germany performed a prostate interventional embolization, and the surgery began. At 16:15, the surgery was declared successfully completed. Now let's watch the surgery recording."

Li Haitao simply finished speaking and then opened the video.

The video playback is not the surgery itself; after cutting out the preliminaries in a short time, what appears is the image of a prostate angiogram.

The guidewire entered the abdominal cavity smoothly, then reached the common iliac and internal iliac arteries, after which angiography began.

The dense vascular network immediately appeared faintly.

Because the surgical video's resolution wasn't high enough, many professors present didn't see which artery led to the prostate's capillary network.

Under Professor Rudolf Wagner's control, the microguidewire was extremely nimble; after entering the internal iliac artery, it continued with super-selective navigation, proceeding along a side branch vessel.

Advancing the microguidewire wasn't particularly difficult, especially at certain bends where it handled with ease.

"Old Wu, is the guidewire specially made?" Director Kong turned his head to ask Wu Haishi, Wu Lao, for his opinion.

"Hmm, looks like it—it's not an ordinary microguidewire." Wu Lao said.

Director Kong shook his head; facing world‑top professors and virtually unlimited financial support, their efforts over this period seemed to have lost meaning.

Perhaps, as Li Haitao said, this line of research no longer needs to continue.

Super-selective, successful.

Between the upper end of the capillary network and the superior vesical artery, Professor Rudolf Wagner, after several attempts, found that he had reached the limit of the microguidewire; it could advance no further, so he introduced a microcatheter and then performed the embolization.

The procedure itself is quite simple; but if you say it's difficult, it's difficult to the extreme.

This is a huge challenge to the operational technique and application of consumables for Interventional surgery.

Wu Haishi Wu Lao sighed to the side, and Director Kong also felt the same.

But just thinking about giving up, he suddenly recalled the back view of someone sitting in CT Shi, wholeheartedly doing CT three-dimensional reconstruction.
