Ruan Bin and Zhang Chao soon found Li Hao again to explain the situation, but in fact, at this point, there was almost no way to delay.

Li Hao can only agree to take the risk of surgery!

After all, wait for another five hours, wait for the blood to come over and then do the operation, it is estimated that there will be no one by then~

Soon the medical office also signed it!

So with only 500 milliliters of blood in stock, this operation was carried out!

In the operating room.

When the anesthesia was effective, Ruan Bin began to operate! He used a median sternal incision!

After the incision is made, cardiopulmonary bypass is established in the femoral artery, right axillary artery and superior and inferior vena cava cannulation, and the innominate artery, left common carotid artery, and left subclavian artery are separated, and the ascending aorta is cooled and blocked.

The ascending aorta is cut transversely from about 1.5 cm above the sinus canal junction, and cardioaponic fluid is perfused through the left and right coronary artery openings. After the cooling was reduced to 28°C, the systemic circulation was stopped, the ascending aorta was cut transversely at the proximal end of the innominate artery, and then the left common carotid artery was cannulated, and selectively anterograde cerebral perfusion was performed through the right axillary artery and the left common carotid artery.

All of the above is extremely smooth.

Zhang Chao was very skeptical that Ruan Bin had done hundreds of similar surgeries?

But he knew that the next step was the key!

He is also looking forward to Ruan Bin's novel overlying aortic arch replacement surgery!

Ruan Bin took the Cronus intraoperative stent system with a suitable diameter, inserted the true lumen of the descending aorta, aligned the proximal end of the stent with the lower edge of the left subclavian artery opening and released it, expanded the artificial blood vessel at the proximal end of the stent to the side of the aortic arch, and cut off the corresponding artificial blood vessel at the opening of the three branches in a wedge shape.

The artificial blood vessel was fixed with a 5-0 prolene thread at the lower edge of the left subclavian artery with a cushion suture, and then the edge of the proximal artificial vessel at the proximal end of the stent was anastomosed with the aortic wall of the arch by continuous sutures to both sides, and the arch reconstruction was completed inside the aortic arch!

"This way of anamousizing...... This route ......" Zhang Chao watched intently, his eyes shining one after another!

Because he found that Ruan Bin's improved version of the anastomosis can avoid endoleakage of the arch anastomosis! When the arch is sutured, the needle insertion and exit are on the artificial blood vessel, and the traction suture must be soft and completed by the surgeon as much as possible to avoid intimal tearing.

In addition, when the posterior wall of the aortic arch is anastomized, full-thickness suture is performed as deep as possible, and when the anterior wall is sutured, a penetrating U-shaped overlapping suture is used to insert the needle from the aortic lumen and exit the needle from the aorta. This simple and practical suture method ensures closure of the arch lumen without tearing damage to the arch lining.

No wonder Ruan Bin said before that it is simple, direct and effective! It can also greatly reduce the operation time.

Ruan Bin just changed the surgical anastomosis route, and made the operation streamlined and pleasing to the eye!

At this time, Ruan Bin used a 4-0 prolene line to complete the proximal arch forming, so that the proximal end of the arch was covered by artificial blood vessels except for about 1/4 of the upper part. Two pieces of artificial blood vessels about 5 mm wide were cut from a branch of artificial blood vessels, lined inside and outside the 1/4 position not covered by the artificial blood vessels, and sutured.

In this way, the proximal end of the aortic arch is covered by artificial blood vessels. The proximal aortic end of the arch is attached to the aortic wall with an artificial vascular piece, and the proximal end of the arch is anastomosed with the main body of a branch artificial blood vessel with a continuous suture with a 4-0 prolene suture. After exhausting, the whole body circulation is restored, and the temperature is rewarmed. The proximal end of the ascending aorta is anastomosed with the end of the prosthetic vessel......

The surgery is complete!

The amount of bleeding is only 300 ml!

This made Zhang Chao pleasantly surprised!

Ruan Bin's surgery avoided the problem that the surgical field was too deep and difficult to anastomosis, and streamlined the operation, reducing the traditional at least 7 hours to 5 hours, and at the same time, due to the small number of anastomosis, it also reduced bleeding, and solved the problem of requiring a large amount of blood transfusion during the operation. This modified technique is very suitable for popularization!

Aortic dissection aneurysm type A is currently the most acute and fatal disease in clinical practice, and is usually treated by surgery in the world, which is recognized as one of the "most difficult surgeries" in the field of cardiovascular surgery.

Now that this modified procedure is available, it will be a blessing for countless cardiovascular surgeons!

This kind of streamlined and practical surgery is definitely easy for many attending doctors to use!

Not to mention the kind of deputy director, director-level veteran driver.

Outside the surgical door.

Li Hao walked up and down the corridor anxiously, he was anxious, his father had been in for so long, and he didn't know what was going on.

He looked at the time, "It's been five hours, hasn't it come out yet?"

At this moment, a nurse suddenly hurriedly came over with several bags of plasma.

"This is ......," Li Hao couldn't help but ask.

"I'll ask if the plasma transferred from other cities is still needed in the operating room. ”

That's when the surgeries opened.

Ruan Bin and Zhang Chao came out of it.

"Dr. Ruan, Director Zhang, how is my dad?" Li Hao asked anxiously.

"The operation was a success! I believe I will be discharged from the hospital in a week. Ruan Bin said with a smile.

"Really?"

"Of course, 300 milliliters appeared during the operation, so the blood was basically enough. Zhang Chao said with a smile.

"Then these plasma ......," the nurse held up the plasma in her hand.

"It's not needed. Ruan Bin said.

"Dr. Ruan, Director Zhang, thank you!" Li Haohu burst into tears.

............

Ruan Bin invented this improved version of the streamlined and novel overlying aortic arch replacement surgery method, which instantly spread throughout the cardiovascular surgery of major hospitals in the magic capital.

After watching Ruan Bin's operation video, many doctors in cardiovascular surgery were amazed!

Obviously, this improved and streamlined surgery has greatly reduced the difficulty of the original operation, and this is not counting, it is also more simplified, reducing the risk and reducing bleeding!

This operation video was quickly uploaded to the surgery forum, which immediately caused many hospitals and cardiovascular surgeons across the country to watch and learn from it.

After all, now Ruan Bin is an Internet celebrity doctor in the surgery forum!

Many doctors of the younger generation and even many doctors of the older generation are very concerned and respected by him!

"This improved technique is really too quintessential! It's as if the twenty-eight palms of the dragon descending have been streamlined to the eighteen palms of the dragon descending, and the power is even more powerful!"

"Compared with the methods commonly used in the world, the operation is simple and easy to master, which reduces the incidence of surgical complications and improves the success rate of surgery!"

In the past few days, Zhang Chao of cardiovascular surgery and an old colleague of his who are familiar with other departments boasted about how Ruan Bin was a cow. It seems that he is the Jade Emperor, Ruan Bin is the Buddha of Rulai, and he can subdue the 'demon monkey' this time by relying on Rulai!

This made his old friend Huang Weilin, the director of the Department of Orthopedics, a little speechless, are you really good at boasting about him like this?
