This miracle doctor just wants to be fired!

"Severe Z-shaped necrosis, completely locked, blood vessels already spasmed, conventional methods are ineffective!"

Zou Liqian's tone was extremely solemn.

Without wasting any words, he immediately took over the operation and personally went on stage to fix the problem.

As the department director and one of the top surgeons in China, Zou Liqian has been deeply involved in interventional clinical practice for more than 20 years. He has seen countless intraoperative complications and instrument accidents, and his experience far surpasses that of younger surgeons like Lin Feng.

After Director Zou got the hang of it, his technique was far more steady and experienced than Lin Feng's.

He first made precise adjustments to the catheter angle, and then tried a variety of advanced conventional remedial measures, such as guidewire support, intraluminal relaxation, and slow torque repositioning.

An ultra-slippery guidewire is inserted to attempt to pass through the bent catheter lumen, using the guidewire to support and open the bend, thus reshaping the catheter's shape.

failure

Then, use a segmented, gentle twisting and gradual loosening method to try to stretch the Z-shaped angle.

Another failure!

He then replaced the guidewire with a rigid one for added support and slowly adjusted the catheter position, but still could not budge the stuck catheter even slightly.

Still failed!

……

With each attempt, Lin Feng and the medical staff around him stared intently at the screen.

He could clearly see that with repeated fine-tuning and traction, the patient's vasospasm became more and more obvious.

The blood pressure reading on the monitor was still slowly dropping, the heart rate was fluctuating, and the heart rhythm was becoming irregular.

More and more warning signs are emerging!

Time passed by, and every second was excruciating.

For a full fifteen minutes, Zou Liqian used every routine and advanced catheter rescue technique available in clinical practice.

All invalid!

"well……"

Zou Liqian stopped operating, released the instrument in his hand, let out a long breath, and his eyes were full of solemnity and helplessness.

The lead apron was heavy and stuffy, and the continuous high-pressure operation made even the most experienced department head physically and mentally tense.

"It's stuck, there's absolutely no room to loosen it." Zou Liqian shook his head. "We've exhausted all conventional interventional endovascular techniques. Continuing with endovascular procedures will most likely rupture the blood vessel or induce massive bleeding. The risks are completely uncontrollable."

Lin Feng's heart sank, and he asked in a low voice, "Director, what do we do now?"

The catheterization lab fell into complete silence, with all eyes fixed on Zou Liqian.

He stared at the tightly bent catheter on the screen, then glanced at the continuously declining vital signs data, remained silent for a moment, and then spoke with difficulty.

"The only alternative at present is to perform emergency surgery to open the chest, remove the bent catheter under direct vision, and treat the myocardial infarction lesions at the same time."

Upon hearing these words, Lin Feng felt a chill run down his spine.

Everyone understood what this plan meant.

The patient had an acute, widespread anterior wall myocardial infarction, was extremely hemodynamically unstable, and had very poor physical tolerance.

Emergency thoracotomy at this moment is extremely invasive and carries a very high risk, with a probability of more than 80% of patients developing serious complications after the surgery.

They might even be unable to back down!

If surgery involves opening the chest, it's like pushing the patient to the brink of death.

"If it can be resolved with minimally invasive endoscopic surgery, no one wants to upgrade to open-chest surgery. But right now all interventional methods have failed, the catheter cannot be removed, the blood vessels are blocked, and the foreign body is stuck. Without open-chest surgery, the patient will most likely not survive the night."

Zou Liqian made the final conclusion.

A dilemma, a dead end.

"Contact the cardiothoracic surgery department immediately and prepare for emergency open-chest surgery. Make sure the preoperative coordination is in place," Zou Liqian ordered in a low voice. "Prepare to communicate with the patient's family first."

The nurse immediately prepared to call the surgery department; the atmosphere was extremely tense.

Lin Feng stood aside, looking at the dead conduit on the screen, feeling utterly defeated.

His first high-risk emergency surgery, which he led independently, resulted in this extremely serious complication, forcing the patient to undergo open-chest surgery to save their life.

The pressure and self-blame were suffocating him.

……

Just as the nurse was about to dial the phone, the door to the catheterization lab suddenly opened.

A calm and clear voice came from the doorway.

"Don't contact surgery yet, wait a bit."

Lin Feng suddenly turned his head.

Zhou Cheng stood at the entrance of the catheterization lab, dressed in a simple home outfit of short-sleeved shirt and trousers, his hair slightly disheveled, indicating that he had just rushed over.

He was standing at the door without wearing a lead apron or changing into surgical scrubs.

But the appearance of this figure instantly calmed the anxiety in the room, making everyone's tense nerves feel a little more at ease.

"Zhou Cheng? Why are you back?" Zou Liqian turned around in surprise. "You're resting tonight, you don't need to rush over."

"I got a call, so I had to come over." Zhou Cheng strode in, his gaze sweeping over us and landing on the X-ray screen. "Let me take a look at the footage."

He walked to the control panel and quickly scanned the shape of the bent tubing.

After a moment, Zhou Cheng slowly said, "We don't need to open the chest yet; we should be able to remove it from inside the cavity."

He said this without the slightest hesitation.

Zou Liqian paused for a moment, then subconsciously said, "I've tried all the conventional and advanced endovascular methods. The Z-shaped dead fold is completely locked, there's no room for loosening, and it's impossible to remove. If we delay any longer, the patient might not be able to hold on."

"If conventional methods don't work, we need to try unconventional approaches," Zhou Cheng said immediately. "This isn't a catheter knot; it's a structural Z-shaped bend caused by the tortuous anatomy of the blood vessel combined with the torque of the instruments. What's stuck is the shape, not the location. Forcing it will only tear the blood vessel. If we use a loop to assist in endovascular repositioning, we can first fix the distal end, and then gradually correct the shape, allowing for controlled loosening."

This plan was something that no one present had ever heard of before.

Zou Liqian also frowned slightly. In interventional procedures, when dealing with catheter bending, the method is always to support the catheter with a guidewire, release the torque, or gradually push and pull it back.

The idea of ​​using rings to assist in resetting has never been used before, completely breaking away from the framework of traditional interventional remedies.

"Prepare the instruments first." Zhou Cheng didn't explain the theory in much detail. "Prepare the vascular loops, the ultra-fine and ultra-slippery guidewire, and oh right, the 2.0 balloon."

Without hesitation, the nurse immediately followed the doctor's orders and quickly prepared all the necessary special equipment.

Seeing this, Zou Liqian also began to cooperate.

Zhou Cheng quickly put on his lead apron.

"Lin Feng, you assist me." Zhou Cheng stepped into the main surgical position.

The two of them worked together incredibly well, far better than when he worked with Director Zou Liqian.

"Okay!" Lin Feng immediately calmed himself down and suppressed all the panic in his heart.

Being able to learn life-saving strategies from Zhou Cheng in such a desperate situation was a once-in-a-lifetime opportunity for him.

It was 7:50 p.m., nearly 20 minutes had passed since the catheter became stuck.

The patient's blood pressure had dropped below 90, and his heart rate was fluctuating continuously. He was at risk of sudden cardiac arrest at any moment, and they had very little time left to save him...
