The surgery is in progress.

After opening the mediastinum on Monday, both he and Director Tian found that the patient's right coronary artery was cuffed off.

At the same time, a tumor was also found at the root of the patient's aorta on Monday.

Typical aortic root aneurysm.

It turned out that the patient's aortic dissection was caused by an aortic root aneurysm.

When Director Tian saw such a result, his brows tightened.

The patient's condition was very complicated.

A surgical treatment is very much a solution for all conditions.

According to Director Tian's decades of experience in extracardiac surgery, the current situation requires at least three surgeries.

One surgery is to address the problem of aortic dissection.

One is to deal with coronary artery occlusion.

The other is of course for the treatment of diseased aortic aneurysms.

All three surgeries require the cardiac to be stopped, followed by a lower body temperature, suspended animation, and the support of cardiopulmonary bypass.

Each operation is taken out separately, and it is the most difficult surgery outside the heart.

Even Director Tian, who was so famous in Qinzhong, was attentive outside of his heart, and when he saw the situation in front of him, he was still apprehensive.

Three surgeries are performed in one piece, which is the largest of the major surgeries.

Director Tian's heart began to worry about Zhou Zhou.

Will he be able to do these surgeries?

Although the operation has just been opened, Zhou Yi showed some strength.

But thoracotomy is compared to these three surgeries.

That's nothing.

At the same time, Director Tian also began to feel that Dean Cheng was prescient.

He thought that if he couldn't stand it for the rest of his life, he could go up and help.

Monday is of course very clear about the current situation.

Before the mediastinum is opened, the system has already given a specific surgical treatment plan.

Bentall surgery, total arch replacement surgery, right coronary artery bypass surgery, three types of surgery are the only options to treat the patient.

Bentall surgery, also known as "aortic replacement with aortic valve prosthetic vessel". It is a surgical procedure for the treatment of ascending aortic aneurysm. The surgery requires the heart to be stopped.

Total arch replacement surgery is one of the most difficult cardiac surgeries, relying on the surgeon's superb technology and high-tech materials, which is a substitute for the largest blood vessel in the human body that is "quick-frozen" to 20 degrees Celsius and quickly cut off the damaged upper end of the heart. The aim is to treat the aortic arch in which dissection is present.

Right coronary artery bypass surgery, just listen to the name. This surgery is to build a bridge between the blood vessels. The specific method is to take the veins of the lower extremities as the material of the bypass, and also under the cardiopulmonary bypass, to stop the heart and bypass the aorta between the distal end of the coronary artery lesion.

All of these three surgeries were extracardiac fourth-degree surgeries.

Monday was in the director's copy last night, and these surgeries were done.

But in the copy, he also did three such operations at the same time in one operation.

Zhou Zhou muttered in his heart, good guy, this is a rhythm that is enough for once!

This one operation is worth three major surgeries in the dungeon.

Three surgeries, estimated on Monday, are not done in 7 or 8 hours, which cannot be done.

Roll up your sleeves and just say "dry"!

Let's start with the Bentall procedure.

The right femoral artery is inserted into the donor vessel......

The right atrium is inserted into the draining ......

When the body temperature drops to 26°C, the ascending aorta distal to the lesion is clamped and the cardioaponic fluid is perfused.

Free ascending aorta, resect the diseased segment of the ascending aorta, retain its posterior and left and right coronary artery openings, resect the aortic valve, transplant the artificial blood vessel with the valve, and then transplant the left and right coronary arteries to the artificial blood vessel, and the artificial blood vessel is anastomosed with one end of the distal row end of the ascending aorta.

……

Monday is a day to bury your head in the fight.

As a helper, Bai Mingming couldn't intervene at all.

He has never experienced extracardiac surgery, and he is no better than Su Quan and Cao Xin.

Only watch Monday be busy with work.

Occasionally do odd jobs.

The surgery was very stressful.

Director Tian was originally watching from a relatively remote position, the operation was too nervous, and in the end, he couldn't help but come to the side of the second assistant Su Quan.

Su Quan, the second assistant, is basically the same as Cao Xin, he is an audience. In this operation, it didn't work at all.

So when he found Director Tian approaching, he took the initiative to give up his position to Director Tian.

Director Tian nodded at him and said, "Thank you." ”

Director Tian has a good position, and he pays more attention to Zhou Sheng's every move.

There are many small details to be aware of in the Bentall procedure.

Monday was very meticulous in handling it.

Director Tian is a master outside the heart, and when he looks at Zhou Yisheng's operation, he knows that Zhou Yi is experienced and has been instructed by a master.

Yes, Lao He in the system taught him meticulously, and as soon as she made a mistake on Monday, she would deduct points and re-operate.

So the technology of the week, that's very solid.

Four hours later, Bentall's surgery was completed.

But this is only the first step in this operation.

Next, a full bow replacement is performed.

Lift your spirits on Monday and keep going.

After four hours of surgery, even Su Quan, Cao Xin and others felt a little tired from watching from the sidelines.

Monday was also a little tired, but he didn't have time to rest.

In front of me, the aortic arch, which was originally only 3 cm in diameter, has been stretched 7 cm thick by dissected blood, and the blood vessel wall is thin and transparent, and it will rupture at any time.

Surgery must be carried out against the clock.

Monday under the doctor's order.

Cardiopulmonary bypass device control, blood temperature drops.

The blood temperature slowly began to drop and finally settled at 20 degrees Celsius, which is 17 degrees Celsius lower than the normal body temperature of 37 degrees Celsius.

Cardiopulmonary bypass is stopped and the aortic arch is replaced.

In a low temperature state, the human body can be "quick-frozen" for about 40 minutes, and no matter how long the time is, it will not work.

Monday has half an hour for the replacement work.

Therefore, one of the most difficult extracardiac surgeries is not only a test of teaching skills, but also a test of proficiency.
