The operation entered a new phase.
This was something no one had ever seen before, and everyone was staring at Li Zheng's operation with curiosity.
Just then, the door of the operating room was pushed open and two people came in.
Everyone turned around and saw that it was Xiang Yuanzhong, deputy director of surgery, and the other one was Duan Jianhui, director of the Municipal Hospital.
He has been here twice and almost everyone knows him.
"Director Xiang, Director Duan, you are here!" Bao Youshan greeted them with a hint of pride on his face. Li Zheng's operation went smoothly, and he also benefited from it.
Dean Zhang frowned. He didn't even know Duan Jianhui was coming. He definitely wasn't coming to perform this operation, and Xiang Yuanzhong hadn't even informed him.
"Haha, you guys continue, we just came here to visit." Xiang Yuanzhong said with a smile.
"Director Duan, long time no see! What surgery are you performing today?" Director Zhang smiled wryly and extended his hand.
Duan Jianhui shook hands with Director Zhang and said, "Director Zhang, long time no see. I'm here to help Director Xiang with his procedures. He has a hip replacement today."
Dean Zhang glanced at Xiang Yuanzhong.
Xiang Yuanzhong said embarrassedly, "Director Zhang, the surgery has already been approved by the hospital, the medical department has reported it, and Director Wang has signed it. I wanted to report it to you yesterday, but you went to the Health Bureau for a meeting, so I forgot to tell you today."
Hip replacement is a level 4 surgery and must be reported, not to mention that an expert must be invited and the hospital must agree.
Dean Zhang sneered in his heart, thinking that these people did not take him seriously.
"Since Director Duan is here, there's no problem. You can arrange it." After saying that, Dean Zhang began to concentrate on watching Li Zheng's surgery.
Duan Jianhui had long been drawn to the surgery on the stage. Seeing Li Zheng harvesting the great saphenous vein, he showed a surprised expression. This guy really dared to do this. He couldn't help but ask, "Doctor Li, when did you learn how to perform vascular transplant surgery?"
Li Zheng didn't turn around, continuing to focus on the operation. He said in a deep voice, "Director Duan, this isn't a difficult operation. You can learn it by reading a book!"
Li Zheng's words made everyone feel upset. Duan Jianhui was even more amused and said, "You are really a genius. You can do it just by reading books. We can't do it!"
Chen Dayong helped Li Zheng pull the skin off his thigh to make the operation easier. He smiled and said, "Director Duan, it's really not that difficult. As long as you have a good understanding of anatomy, you can perform any surgery!"
Chen Dayong's words made everyone think that he was also a madman.
Zhang Lei chuckled and said, "If Li Zheng had said this, I would have believed it. What you said, although it makes sense, it doesn't suit you!"
Chen Dayong snorted coldly and said, "Zhang Lei, don't look down on me like that. This applies to any gifted doctor, and I am that gifted doctor. What's more, this was indeed said by my brother Zheng, and he encouraged me. This shows that my brother recognizes my talent!"
Zhang Lei nodded and said with a smile, "Then when I see you perform some difficult surgeries alone, I will recognize you!"
Chen Dayong nodded and said, "Just wait, one day I will blind your eyes!"
Duan Jianhui listened to their conversation and shook his head. It seemed that the operation went very smoothly, otherwise they wouldn't be chatting so easily.
Xiang Yuanzhong curled his lips, looked at Duan Jianhui and said, "Director Duan, the anesthesia over there should be almost done, let's go over there!"
Duan Jianhui shook his head and said, "The great saphenous vein has been removed. I want to watch Dr. Li sew it up next. You go and disinfect and prepare first."
Xiang Yuanzhong hesitated for a moment and said, "Then I'll accompany Director Duan to take a closer look. Doctor Guo is over there preparing it and will call us when it's ready."
Li Zheng removed a 10-centimeter section of the great saphenous vein. Because the bruised part of the popliteal artery and vein was cleaned, the defect should be about 8 centimeters. Part of the two ends of the cut great saphenous vein also had to be trimmed off, so the length should be just right.
The stump of the great saphenous vein in that leg will be ligated. That leg will be edematous for a period of time because the blood flow has deteriorated, but the lumen of other veins will gradually increase, and it will not take long for them to compensate and adapt.
"Bring the needle and thread." Li Zheng clamped one end of the great saphenous vein with a small curved forceps, and Lin Xiaomei immediately handed it to him.
"Are you going to sew it up? It's so long, won't you cut it off?" Chen Dayong asked.
Li Zheng shook his head and said, "Veneres all have valves. Blood can only flow from the distal end to the proximal end, not back. Therefore, they must be marked properly. The direction of the arterial transplant must be opposite. Otherwise, blood circulation will be severely restricted and the anastomosis will easily tear!"
Chen Dayong suddenly realized and wanted to slap himself in the face. It was not like he didn't know about the existence of venous valves, but he just didn't think about it at the moment. He just said that as long as he was good at anatomy, he could perform any surgery he wanted, but in the blink of an eye, he was slapped in the face.
Duan Jianhui nodded, then shook his head. He approved of Li Zheng, but was very disappointed with Chen Dayong. He didn't even understand the most basic points of vascular transplantation, but he just talked big.
Xiang Yuanzhong was watching Li Zheng's operation, curious about how he would sew next. After all, he had only heard about this kind of surgery, but had never seen it in person. To perform vascular anastomosis, one would at least need to wear a pair of microscope glasses.
After marking the great saphenous vein, Li Zheng cut it in the middle, trimmed the inner and outer membranes of the broken ends, and began to prepare for suturing.
The arteries are anastomosed first so that blood can be supplied to the limb as quickly as possible.
Bao Youshan removed the gauze from the wound and sucked out the blood with a suction device.
Li Zheng used low molecular weight heparin calcium to flush the blood vessel cavity to prevent blood coagulation.
After placing the vein at the defective site of the popliteal artery, Li Zheng asked for a 4-0 non-damaging nylon thread and began to suture the broken ends with an outward-turned mattress suture, which could reduce the impact of the broken ends on the blood.
