Under the shadowless lamp, Xu Qiu's hand speed became faster and faster, and in the end almost all the afterimages appeared.

His voice was still slow and not urgent.

"Elephant trunk stenting can stabilize the dissecting descending aorta around the stent graft, allowing rapid closure of the false lumen.

In the past, clinicians selected the type of artificial blood vessel based on the diameter of the true lumen.

However, problems were discovered later. Doing so could easily lead to distal endoleakage or unblocking of the false lumen, so doctors could only hope that thrombus would form in the false lumen during follow-up, leading to closure of the false lumen...

If there is still no closure during the follow-up period, endoluminal repair surgery will be necessary.

Therefore, after that, the surgeon will choose the size of the stent graft based on the total diameter of the aorta at the level of the left atrium. The best preoperative auxiliary examination...

What is it?"

When the last question came out, everyone's hearts suddenly tightened.

Many eyes fell on Yang Yuen.

After all, in the operating room, there are either famous doctors like Joseph or Director Zheng, and only Yang Yuen has the lowest professional title.

"Yes... yes, CT angiography?" Yang Yuen blurted out.

Xu Qiu nodded slightly: "Not entirely correct. If you want to estimate the size of the covered stent, the best imaging method is to perform multi-dimensional reconstruction along the center line of the curved blood vessel from ECG gating to CT angiography."

To put it simply, it is multi-dimensional reconstruction.

This is not much different from the examination method relied on by the complete cranial fusion and separation surgery at the beginning of the year. Reconstruction is basically the trump card of various top surgeries. By completely reconstructing the patient's anatomy and displaying it in front of the doctor, a more personalized treatment can be formulated.

More detailed surgical plan.

Xu Qiu added: "In emergencies, reconstruction cannot be done, so we usually rely on intraoperative esophageal ultrasound measurement, or intraoperative esophageal ultrasound during CT angiography."

Such as now.

This patient with ruptured dissection was in very serious danger. On the way to the hospital, he had already lost nearly 1,200 milliliters of blood and was already on the verge of death.

Therefore, detailed imaging examinations cannot be performed, and everything can only be carried out simultaneously during the operation.

“In addition to the size, the length and depth of the covered stent implantation are also very particular.

The longest, distal anchoring zone cannot exceed the T10 segment.

In fact, once T7 is exceeded, the incidence of spinal cord injury increases significantly.

Therefore, the seventh thoracic vertebra should be used as the boundary in clinical work, and the stent cannot cover the celiac axis..."

The highly difficult modified SUN surgery was performed by Xu Qiu as if it were done with ease, and he was able to teach at the same time.

Mention details from time to time to make the eyes of everyone watching shine.

Finally, as the surgery progressed, it came to the elephant trunk stent surgery!

"What I want to do next is an advanced and improved version.

There is another version, which is less difficult to operate and tends to be more tricky. It is suitable for most doctors to learn. I will also make it public in the cardiac surgery department in the future.

What I want to do is an improved method that has a higher threshold, but once mastered, the speed is faster than using tricks."

After saying that, Xu Qiu moved his knife.

Elephant trunk stent surgery, scientific name is "hybrid aortic replacement surgery".

Its surgical method is simple to say, that is, using artificial blood vessels to replace the diseased aorta and aortic arch, and introducing artificial blood vessels with stents to seal and block the intimal breach of the blood vessels and expand the vacuum cavity.

Xu Qiu made many improvements based on the original.

In addition to the double-stacked three-layer method, Xu Qiu also introduced a three-branch stent in aortic replacement.

…

Modified elephant trunk stenting began soon.

The right axillary artery and femoral artery were cannulated for perfusion;

The left subclavian artery and left femoral artery were punctured and guide wires were inserted respectively;

The aortic arch is severed between the innominate artery and the left carotid artery;

Then, pull out the guidewire for puncture of the left subclavian artery and left femoral artery, and penetrate the main trunk and branches of the stent vessel;

After that, the stent vessel is extended into the descending aorta and the corresponding brachiocephalic artery...

"call."

Everyone held their breath and stared nervously at the surgical area.

Xu Qiu also calmed down, and after concentrating again, he gently released the branches of the left common carotid artery and the left subclavian artery.

Everyone's hearts were in suspense.

Release successful!

Xu Qiu did not stop and released the main stent in the descending aorta.

"Balloon."

The first assistant, Director Zheng, understood and immediately started to use the balloon to confirm whether the stent was fully released. Director Zheng's surprised voice soon came out, "Success!"

There was a low sound of celebration in the operating room.

Joseph, Saitono and others were also extremely happy. When they came back to their senses, they realized that their palms were already sweating.

It really worked!

Double-stacked three-layer technique...

Three-branch bracket...

There is also the short elephant trunk technology, the design of leaving about one centimeter of stent-free bare area, etc. Each innovative technique is dazzling.

"I want to learn!" Joseph swallowed crazily, his eyes almost dry.

Yang Yuen in the corner couldn't help but smile.

Professor, Professor, did you agree to return to Cleveland Medical Center in three months?

Three months and three months, if you don't leave, you will become the chief physician of the clinic!

Xu Qiu finally completed the suturing of the proximal main trunk and distal aortic arch incisions and concluded the entire operation.

While Director Zheng and the other doctors were shocked, they also breathed a sigh of relief.

Finally, Joseph was left behind...

These famous doctors looked like they were having sex for free.

In fact, just by staying in the clinic, they can bring great benefits to the hospital.

As long as some people are alive, their meaning is greater than anything else.

Joseph is obviously someone with this qualification. As a contemporary authority in cardiac surgery, he can gain the attention and respect of cardiac surgeons around the world wherever he is!

"We will strive to push the clinic's cardiac surgery department into the top three in the country during this period of time!" Director Zheng and others are full of confidence.

With Xu Qiu's surgery and Joseph, a living fossil, the development and construction of clinical cardiac surgery is simply bright!

…

…

In the next few days, Xu Qiu used his free time to compile two versions of the elephant trunk brace technique.

One is reserved for cardiac surgery, an improved version of the system and skills.

Similarly, Xu Qiu does not intend to keep this technology secret, and plans to publish the details of the surgery to the whole country and the world in the next issue of "Linhai Doctor"!

As a surgery closely related to aortic dissection and other lesions, the importance of elephant trunk stenting is greater than imagined.

Xu Qiu does not intend to monopolize it. Only by promoting it can it benefit more patients.

After all, aortic dissection is an emergency, and patients with aortic dissection can die within half an hour, so they can only choose the nearest hospital for treatment.

Even if clinical doctors keep hiding the reform, it will not bring more patients to the hospital... Only if it is made public for free and can be mastered by more hospitals and doctors can patients truly benefit.
Chapter completed!
