The hospital is too busy, so I'm going to join the army and become a top soldier!

As blood flow resumed in the radial artery, the originally pale skin of the severed limb gradually regained some color.

Everyone in the operating room breathed a sigh of relief.

The attending physician on duty couldn't help but exclaim excitedly:

"It's connected!"

"The radial artery is really open!"

Shen Yan did not relax at this moment.

He looked down to observe the color and swelling of Han Dayong's right hand, and then checked the capillary reaction at the fingertips, his expression remaining serious.

"It's not over yet."

"Right now, only blood can get in."

"Venous return has not yet been established. If blood can enter but cannot return, the severed limb will quickly become congested and swollen."

"I still can't save this arm!"

The joy on the attending physician's face vanished instantly.

He realized he had been too happy too soon.

The restoration of blood flow in the radial artery only proves that the bridging anastomosis was successful.

However, the ulnar artery has not been treated, and the main venous return has not been reconstructed!

This surgery is just the beginning of the most dangerous hurdle; there are still many more challenges ahead!

Zheng Guoliang sat down in front of the microscope again.

But he stopped just as he reached out his hand.

He is getting old, and coupled with long hours of high-pressure work, his fingers are showing signs of fatigue.

The amplitude is very small.

It's difficult for ordinary people to even tell.

Microvascular anastomosis is an operation performed within millimeters.

Even the slightest tremor can damage the vascular endothelium and even cause problems at the anastomosis site again.

Zheng Guoliang looked down at his hands.

Then he looked at Shen Yan.

He did not continue to force himself to stay in the operating room just because he was the lead surgeon.

For a doctor, the patient's life and the outcome of the surgery always come first!

Whoever has the better skills should be the lead surgeon!

"Shen Yan".

Zheng Guoliang said in a deep voice:

"You handle the remaining anastomosis of the ulnar artery and the main vein!"

The attending physician on duty was stunned.

The operating room nurses couldn't help but look at Zheng Guoliang as well.

Zheng Guoliang had just asked Shen Yan to try to complete one end of the vein bridging.

Now, however, he has voluntarily handed over the most crucial subsequent microvascular anastomosis to Shen Yan.

What does this mean?

This means that Zheng Guoliang has completely approved of Shen Yan's actions!

A new recruit who just joined the army, and a freshman at Fudan University School of Medicine!

Incredibly, he earned the surgeon's absolute trust during this highly complex limb replantation surgery!

Does the concept of genius really exist in this world?

And they saw it with their own eyes!

Shen Yan did not refuse.

"yes!"

He sat back down in front of the microscope and began to treat the ulnar artery.

The ulnar artery is not damaged as extensively as the radial artery.

However, after the detachment was completed, Shen Yan still found that the inner lining of some blood vessels that appeared normal on the surface had been slightly bruised!

If anastomosis is performed directly to save time, blood flow may be restored in a short period of time.

However, once a blood clot forms, the consequences will be even more serious!

Shen Yan decisively removed the damaged portion and re-repaired the severed ends of the blood vessel.

The lengths of both sides are just right to allow them to align without tension.

Shen Yan's every movement was frighteningly steady.

The attending physician on duty next to him originally wanted to help remind him.

After looking for a long time, he still couldn't find anything that needed to be pointed out!

The stitch spacing is even, the edge distance is consistent, and the stitch strength is controlled just right.

It can ensure accurate alignment of the vascular intima without causing anastomotic stenosis due to overly tight sutures.

The entire procedure went so smoothly that it was as if Shen Yan had performed this surgery countless times before!

The attending physician on duty grew increasingly silent.

He is clearly an attending physician at a military hospital.

I have participated in countless surgeries, both large and small.

But after standing next to Shen Yan, he actually had the illusion that he was the intern!

This feels so outrageous!

The ulnar artery anastomosis was completed quickly.

The clamp slowly loosened, and the blood flowed smoothly through the anastomosis without any leakage!

There was no vasospasm or anastomotic stenosis!

"The ulnar artery is clear!"

Shen Yan did not stop and immediately began to treat the main veins.

Compared to arteries, veins have thinner and softer walls.

Under a microscope, even slight overstretching can cause collapse, curling, or twisting.

Insufficient venous return can also lead to rapid congestion and swelling of the severed limb.

Shen Yan first confirmed the location and extent of damage of all major reflux veins before starting to anastomose them one by one.

By this time, the surgery had been going on for a long time.

The operating room nurses' legs were a little sore.

The attending physician on duty also began to experience stiffness in his neck and shoulders.

Zheng Guoliang maintained a high level of mental concentration throughout, and his eyes became bloodshot.

Even while sitting in front of the microscope, Shen Yan's hands remained steady!

Even after completing multiple vascular anastomoses in succession, his movements did not show any obvious distortion.

As the main venous return gradually established, the color and temperature of Han Dayong's right hand began to recover further.

The previously sluggish capillary reflex in the fingertips gradually became more pronounced!

The attending physician on duty immediately brought the Doppler equipment for inspection.

A clear blood flow signal was transmitted.

"Arterial blood flow is present!"

"Venous return is temporarily stable!"

Only at this moment did Zheng Guoliang truly breathe a sigh of relief.

The most dangerous phase of ischemia is finally over!

Too much time has passed since Han Dayong was injured.

If the delay continues, the damaged muscle and nerve tissue will become even more inactive.

Fortunately, they didn't wait for the experts!

Even more fortunately, Shen Yan completed the most crucial microvascular anastomosis!

Han Dayong's right arm finally has a real chance of being saved!

However, the restoration of blood flow does not mean the surgery is over.

While bones and blood vessels are being reconnected, the numerous severed muscles, tendons, and nerves still require further repair.

If these structures cannot be restored, even if the right hand eventually survives, it will be difficult to regain normal motor and sensory functions.

"Continue the surgery!"

Zheng Guoliang quickly made arrangements for personnel.

The attending physician on duty is responsible for assisting in the treatment of flexor and extensor tendons.

Zheng Guoliang reconfirmed the fixed bones and major muscle tissues.

Shen Yan then continued to cooperate in completing the tendon alignment.

Tendon repair cannot simply involve suturing.

Tension, length, and subsequent sliding function also need to be considered.

If the stitches are too tight, it may affect joint movement.

If the stitching is too loose, it will not be able to effectively transmit muscle power.

Every time Shen Yan treats a tendon, he reconfirms the position and tension at both ends.

He was very fast, but he didn't skip any necessary steps in pursuit of speed!

The attending physician on duty was initially worried that Shen Yan was only good at vascular anastomosis.

But after seeing his tendon repair, that worry completely disappeared.

He was very puzzled. What was there that this kid couldn't do?

At the same time, he began to doubt whether he was already outdated!

Could it be that top medical schools are now teaching limb replantation in their first-year courses?

Even if the school were to actually teach it, no first-year student could possibly learn to that level!

"Does this kid have a system?"

Suddenly, an absurd conjecture popped into the mind of the attending physician on duty.

But then he thought about it again and rejected the idea!

After all, if he had a system, why wouldn't this kid just come to the hospital instead of becoming a soldier?

Unless he's out of his mind!

……

After the major tendon repair is completed, the surgery enters the nerve repair phase.

The median nerve, ulnar nerve, and radial nerve branches had already been marked during the debridement process.

Shen Yan sat down in front of the microscope again.

He reshaped the severed nerve ends and then precisely aligned them according to the course of the nerve bundle.

Under a microscope, nerve repair is also an extremely delicate process.

Any significant misalignment could affect Han Dayong's future sensory and motor recovery in his right hand.

Shen Yan controlled the equipment and steadily completed the operation.

Time passed second by second.

The only sounds in the operating room were the regular beeping of the monitors and the occasional exchange of instruments and reports on patients' conditions.

Just as the surgery was in its second half, the operating room door was pushed open.

Zhou Jingshan, director of the microsurgery department of the PLA XX Hospital, who was away attending a meeting, finally returned to the military hospital!

After receiving the news, he urged the driver to hurry back.

Upon arriving at the hospital, without even having time to go back to the office to change clothes, I rushed directly to the operating room to find out what was happening.

Upon learning that the surgery had already progressed far beyond what was intended for him, Zhou Jingshan's expression immediately changed.

He had already seen the medical records on the way.

Han Dayong's injury was not a simple cut, but a complete amputation of his right forearm caused by machinery!

Blood vessels, nerves, tendons, and muscle tissue all showed varying degrees of contusion!

Even if he were to perform the surgery himself, he couldn't guarantee that the replantation would be successful given the complexity of the injury!

The attending physician on duty today is his apprentice. Although he has a background in microsurgery, he is also very familiar with the techniques.

Although Zheng Guoliang is an experienced surgeon, even if the two of them combined their skills, they wouldn't be able to complete this operation!

"Has the blood flow been restored?"

After changing his clothes, Zhou Jingshan washed his hands and asked his assistant a question.

The assistant replied immediately:

"The reconstruction is complete. The radial artery underwent an autologous vein graft, and the ulnar artery and main veins have also been anastomosed!"

"The surgery was performed so perfectly that the video could easily be used as an instructional video!"

Upon hearing this, Zhou Jingshan abruptly stopped moving!

"Is it really all cleared?"

"Currently, the blood flow signal in the Doppler ultrasound is normal, and the color and temperature of the right hand are recovering."

Zhou Jingshan was completely stunned.

He was prepared to rush back to the hospital to take over the aftermath and even redo the anastomosis.

Before I even entered the operating room, I was told that the most difficult part, blood flow reconstruction, had already been completed?

What's going on?

He was very clear about his apprentice's and Lao Zheng's abilities.

When did the two of them reach this level of surgical skill?

Did they secretly evolve without our knowledge?

He immediately changed into his surgical gown and entered the operating room.

The first thing Zhou Jingshan looked at wasn't the operator, but Han Dayong's right hand lying on the hospital bed.

The skin color on my right arm is returning, and there is a capillary reaction at my fingertips.

Although the severed limb still had some swelling, there was no obvious venous congestion!

Doppler equipment can also detect clear blood flow signals!

It's really connected!

Moreover, the blood flow recovery was better than he had expected!

Zhou Jingshan immediately went to the microscope and began to examine the completed vascular anastomosis.

The ulnar artery anastomosis is smooth.

The stitches are evenly distributed.

The blood vessels were not twisted or significantly narrowed.

Major venous return is also unobstructed!

When he saw the autologous vein bridging segment of the radial artery, his eyes changed completely!

The transplanted vein was in the correct direction, and there was no obvious leakage at the anastomosis sites at both ends.

The vascular intima was neatly aligned, and the length and tension of the entire bridging segment were controlled almost perfectly!

This is not a case of forcibly reconnecting the blood vessel!

It is a result that is so accurate that it can be presented as a classic case at a microsurgery academic conference!

Zhou Jingshan asked subconsciously:

Who performed the radial artery grafting?

The operating room fell silent for a moment.

The attending physician on duty raised his hand with a complicated expression and pointed to Shen Yan, who was repairing nerves in front of the microscope.

"he."

Zhou Jingshan looked in that direction.

Shen Yan was wearing a mask and a surgical cap, so all that could be seen was that she was very young.

Zhou Jingshan's first thought was that the hospital had transferred a young microsurgeon from elsewhere.

"Which hospital did you come from for further training?"

Zheng Guoliang replied:

"Shen Yan is not a doctor yet."

"He's a new recruit who just joined our regiment this year!"

"He...is a medical genius!"
