It is easier to sew the opening at the back first, and then sew the vascular anastomosis at the front after the heart is in a good position.
Swish, swish, the surgeon's hand held the needle pliers and tweezers, and the suture passed through the blood vessel wall lightly. The experienced man sewed it very quickly. After a while, the first and most difficult left pulmonary vein group was sutured.
Okay, let’s come to the right pulmonary vein group that also belongs to the posterior wall of the left atrium.
There seems to be a little difficulty here.
Several assistants have been helping with suction, retraction and thread trimming. Now when they saw the main surgeon pause, everyone's hearts trembled.
It has been said that the whole-hearted approach is difficult, and it is even more difficult to apply it to children's cases. Dr. Cheng Yuchen lamented in his heart. I wonder if his boss has not done enough such surgeries and has been forced to lower his vigilance in this regard. You know,
Mu Yongxian, who lives next door, did three cases this year and never dared to use the whole-hearted method.
Don’t think that if the recipient’s pericardial cavity is expanded and the donor heart can fit in, it will be completely suitable? Absolutely not. Each human body has its own details. Now that one person’s heart is placed in another person’s body, this donor heart
It is definitely not an original accessory. It is reflected in not only the size difference in the anastomosis, but also the shape and spacing difference. You can trim the shape and size difference and force it to pull out, but the spacing difference is the most terrible. Think about the last operation on the child who was electrocuted. Can you
Is it because Dr. Duan's repeated failures in suturing are due to his bad taste? He can also be regarded as a child of the Cao family. His defeat lies in the distance.
Why do many doctors like to use the bicaval cava method to kick out the left atrium? Because these two anastomoses are, firstly, on the posterior wall and the operating field is too tricky; secondly, in order to reduce the number of anastomosis operations, they are directly trimmed and cut off.
, which means that a large section must be cut off first. If the distance between the two trimmed cuffs of the donor heart is not exactly the same as the distance between the two openings of the recipient, there will be no room for you to pull hard. It is better to leave half of the left atrium.
Easy to move.
It's impossible to say that a big boss like Brother Shenxian didn't consider this in advance. Maybe he thought it was almost the same, but after actual operation, he found that, alas, the distance was a little larger than the visual distance, just a little short of that, which was tricky.
The scary thing about this operation is that it did not leave the doctor any extra time to think. Why was it said last time that the operation on the child who was electrocuted was relatively simple? Comparing this operation, we can see that the operation time is limited for the surgeon.
It's a high threshold.
We must decide as soon as possible and decide what to do next as soon as possible.
All the staff in the operating room were sweating hotly.
At this moment, the electronic clock on the wall is beating every second, as if announcing the countdown to death.
"Mr. Cao, I think we can sew a stitch into the inferior vena cava first," Xie Wanying said.
The other people's eyes suddenly fell on her face.
Inferior vena cava? Why? If the inferior vena cava is sutured first, the heart is aligned and the vision is blocked. How can I continue to suture the anastomosis at the back? It sounds wrong.
"One stitch." The surgeon said.
"Yes. Sew a stitch and set a fulcrum. You need to calculate the approximate maximum tension that the suture can withstand."
It’s not easy to get into Xie’s brain. A group of people were in a state of confusion after hearing this. Countless gold stars seemed to be spinning above the head of the third assistant, Dr. Cheng Yuchen, who directly smeared “生无” on his brow.
Kelian: Why can't he understand what this student is saying at all?
