Chapter 2546 [2546] Pruning
The right atrium of the recipient was removed, leaving only the left atrium, and the others remained unchanged. This can avoid the disadvantages of having two sinus nodes, and save the most troublesome left atrium pulmonary vein anastomosis time.
Dr. Ye Chuanguang quickly heard that they might adopt the double-caval method or the whole-heart method, because if the double-chamber method is used, there is no special order to keep enough vena cava length for the subsequent anastomosis of the donor heart and recipient.
Whether such a nine-year-old child will challenge the most difficult whole-heart method is estimated to wait until the donor heart is sent to the operating room in Seoul, and the specific situation will be seen after the child is placed in the thoracic pericardium.
In the end, now that he knew what kind of surgery they might be planning, Dr. Ye Chuanguang said to them: "I will help you to trim it as carefully as possible, so that it is convenient for you to operate. After all, the journey is relatively long."
Xie Wanying and the teacher in Seoul must be very grateful for the willingness of the opposite hospital to help.
When it comes to the donor heart being removed from the donor, the surgeon will do a preliminary pruning. Like before, if there is no request from Seoul, the surgeon will come by himself, and will not say that the length of the superior and inferior vena cava in the right atrium should be preserved.
Knowing that they may need double-vena cava or whole-heart anastomosis, Dr. Ye Chuanguang, who is also a cardiac surgeon and has undergone heart transplantation, knows that the anastomotic ends of the pulmonary veins on both sides of the left atrium are the most difficult to deal with. As a doctor who takes the donor heart, he can help his colleagues to trim this place one step ahead: remove all the tissue between the left upper and lower pulmonary vein group and the right upper and lower pulmonary vein group on the back wall of the left atrium, forming two large The cuff and the anastomotic end of the receptor have changed from four to two at once, reducing the suture steps.
In this way, the matters that need to be coordinated are basically over, and after verifying that the other conditions are correct. It was just waiting for Dr. Duan to take classmate Pan to the First Affiliated Hospital of Zhongshan Medicine to get a donor heart.
Rough estimates are flying around for hours, and there is no need to rush the child into the operating room. Before that, Xie Wanying and Wei can go to the PICU to accompany Zhu Xing.
Zhu Xing looked at his brothers and sisters and said, "When will my sister come back?"
After living in the PICU for a while, this little boy has the consciousness of being an older brother. Don't worry about yourself, first worry about the situation of the little sister in the next bed.
Regarding Xiaohui's surgery, Xie Wanying and Wei students remembered that they seemed to have heard other doctors mention it when they were in the doctor's office: the donor heart that Xiaohui needed was not far from the capital. Dr. Han took the hospital ambulance to the destination hospital and came back. It is estimated that four hours will be enough. No wonder Xiaohui was pushed into the operating room early to prepare.
According to this timetable, Xiaohui should be anesthetized and ready to have her chest opened. The specific start time of the thoracotomy should be when Dr. Han confirms the donor heart at the donor's hospital.
The operation cannot be started prematurely, and the operation time is too long, which is a kind of harm to the child. More importantly, I am afraid that there will be variables when taking the donation. For example, Dr. Han went there and found that the donor heart was not suitable for his patient, so he had to refuse it. The probability of this variable is very low, but before the item is in hand, no one can say badly.
Later you will find that the size of the donor heart is not the most feared thing in organ transplantation.
After Zhu Xing fell asleep, Xie Wanying and Wei Shangquan walked out of the PICU.
