Chapter 674: 664 The Skill Still Isn

The guidewire went down again.

This time the wire‑tracking took longer; even Zheng Ren couldn't blindly advance into one of the many branches of the distal anterior tibial artery.

Looking at the blurry image, Su Yun narrowed his eyes to a slit. Artifacts were everywhere, the image was so blurred it couldn't be recognized, and the tiny microguidewire inside overlapped with other images, making it impossible to discern.

How did Zheng Ren confirm the microguidewire's position?

Su Yun didn't know; even with his skill he could only roughly guess… maybe… approximately where the microguidewire was. To actually manipulate it to perform a super‑selective vessel maneuver—that was simply impossible.

But just knowing roughly where the microguidewire was was enough.

Su Yun's level wasn't enough to perform Shou Bing, but it was enough to watch Shou Bing.

In the blurry image, the microguidewire that Su Yun "saw" steadily advanced distally, super‑selectively entering the dorsal foot artery, after which the thrombectomy catheter entered.

During this time, Su Yun mistook artifacts for the microguidewire twice.

This guy…… Su Yun was speechless.

When did the threshold for watching Shou Bing become so high? Su Yun felt a little odd. He didn't think his skill was lower than Professor Rudolf Wagner's, and as for Gao Shaojie… he was sure he was just a bit stronger than Old Gao.

This isn't self‑praise; during the Di Du earthquake, super‑selective cannulation of the internal mammary artery had already been proven.

But with his level, not to mention doing it, even trying to understand Shou Bing was this troublesome?

It must be that I haven't rested well these past two days, constantly teetering on the brink of life and death, causing severe fatigue.

My vision's gone blurry; that must be it.

Su Yun gave himself a reasonable explanation, and his mind felt a bit better.

Yes, it must be this way, it has to be this way.

The thrombectomy catheter was withdrawn again, and a black‑purple clot was placed on sterile gauze.

"That'll do," Zheng Ren said, letting out a breath.

Su Yun didn't speak, just stared silently. Not even understanding Shou Bing, whatever he said now would only earn a cold retort from Zheng Ren—how boring.

The angiogram showed vascular signals present in half of the dorsal foot.

"That's pretty good," Su Yun said with a smile.

There's no way to put it more plainly: a fifteen‑year‑old in the prime of youth faces amputation, and her life thereafter will be considerably harder.

Although they'd done the best possible—better than anyone expected—saving the lower leg, ankle joint, and even half the foot, it was still a harm to the little girl.

Zheng Ren nodded, called outside, and helped lift the little girl out.

The narrow ventilation opening had been enlarged a bit, but no one had widened that hole. Further demolition—who knew if knocking out a certain section of wall would trigger the collapse of the whole dangerous building.

So as long as it works, it's fine—just a bit of trouble, nothing serious.

Zheng Ren and Su Yun lifted a door‑panel makeshift stretcher, placed one end on the ventilation opening, and shoved the little girl out.

"Uncle, thank you," the little girl waved from the stretcher, rain streaking across her fingertips and landing on her face.

Zheng Ren watched the little girl being swiftly carried away from the dangerous building to a tent, and he stared blankly.

"What are you thinking about, Boss?" Su Yun had wanted to ask Zheng Ren how he judged artifacts versus microguidewire images, but seeing Zheng Ren dazed, he also grew curious and asked.

Zheng Ren sighed and said, "If my skill were a bit higher, I could super‑selectively enter that branch of the dorsal foot artery; the preserved area might be larger. Sigh, the thrombectomy catheter is still too thick."

"……" Su Yun knew Zheng Ren wasn't showing off; he was speaking from genuine feeling.

Zheng Ren's words were full of regret, even a bit of self‑blame.

But precisely because of that, Su Yun felt he'd suffered an even heavier blow.

I could barely manage to see Shou Bing clearly, while Zheng Ren had already identified his shortcomings and was preparing to climb higher.

Damn…… really damn!

"Just thrombectomy isn't enough," Su Yun said.

"I believe in Huaxi Orthopedics Department's level," Zheng Ren said. "All our efforts won't be in vain."

Su Yun fell silent, then nodded.

The hundred‑year‑old Huaxi Medical College and Huaxi Hospital are top‑ranked in the southwest; even nationwide they are colossal institutions.

Huaxi's overall standard is very high—something even Su Yun can't fault—yet in his heart he thinks only Xiehe is the strongest.

Such massive, heritage‑laden medical schools all carry an pride that emanates from their very bones.

Take Xiehe, for example—if someone from Bei Med comes to work, the first department will surely be loudly scolded by the leader welcoming the new colleague: "You Bei Med folks have weak foundations, so you must work harder, or else you'll be left in the dust by Xiehe's staff."

Everyone knows this is the goad tactic, aimed at high‑IQ, highly educated people.

But once those words are spoken, every Bei Med person shouts and studies desperately.

At least five years, there's no need to worry about unstable hearts wanting to go to private hospitals; once they mature, they'll already have been assimilated by Xiehe, constantly saying "we Xiehe" this and that.

All this gossip…… turns out the Boss likes Huaxi—you, an undergrad, claim to be a Huaxi grad, but the school can't even be bothered to acknowledge it, and so on.

Su Yun muttered to himself.

The next patient brought in was that pregnant woman.

Her lower leg was fractured, compressed for a long time, until a jack arrived from behind, lifting the prefabricated slab and freeing her.

But below the lower‑leg's two‑thirds, everything was necrotic black; from the lower leg up to halfway up the thigh, severe swelling developed, accompanied by compartment syndrome.

This necrosis can't be treated with thrombectomy. What Zheng Ren needs to do is properly manage the tissue above the necrotic area, reduce swelling, enrich blood flow, and try to preserve the knee joint.

When it comes time to fit a prosthesis later, missing a joint makes the prosthesis crucially important for the victim.

Just as with the little girl's Shou Bing, Su Yun and Zheng Ren were busy with preoperative prep.

Shou Bing, Su Yun still couldn't get his hands on it.

But that doesn't matter—if someone can do it, that's enough. The ever‑proud Su Yun seems to have found his niche in this rubble, focusing on doing all the chores well so Shou Bing can go faster, even faster.

Thirty thrombectomy catheters really aren't holding up.

Before the generator's diesel ran out, all the thrombectomy catheters had already been used up.
