"You...you sewed it directly under your eyes? Is the effect guaranteed?" Xiang Yuanzhong questioned, incredulous. Although the popliteal artery was as thick as the tip of a chopstick, suturing it with the naked eye was always wrong.
Duan Jianhui didn't question it. He answered for Li Zheng, "The great saphenous vein and popliteal artery are already thick enough. The thinner radial artery can be sutured under direct vision. Of course, this also requires higher standards from the surgeon. Having a microscope is best. If not, then it depends on the surgeon's ability!"
After saying that, Duan Jianhui stood behind Li Zheng and stretched his head to see how Li Zheng was sewing. Unfortunately, the surgical field was too small and he couldn't see clearly.
After performing four interrupted sutures, Li Zheng flipped the vessel over using a pre-set traction line and sutured the other side with four more stitches. A typical vascular anastomosis requires six stitches, but the great saphenous vein has a larger lumen than the popliteal artery, and the two ends don't align, so eight stitches are safer.
Bao Youshan held the traction wire carefully, and if he tore the blood vessel, it would be a big trouble.
"6-0 nylon line." Li Zheng stretched out his hand and Lin Xiaomei handed it to him immediately.
"You just sewed up one port? How many stitches did you sew?" Duan Jianhui asked in surprise.
Li Zheng shook his head and said, "No, I just sewed eight stitches intermittently, and I still need to lock the edges."
Duan Jianhui was speechless. It's only been less than two minutes, and even though it's just interrupted suturing, you've already done eight stitches! At that speed, can you guarantee quality? Eight stitches in two minutes is fast for skin suturing, but you're suturing blood vessels! You can't be so reckless.
Duan Jianhui and Xiang Yuanzhong looked at each other and shook their heads.
They looked at Dean Zhang and found that he had found a round stool nearby and was sitting with his eyes closed to rest.
Li Zheng continued to use thinner thread to carefully suture the anastomosis, leaving no dead corners as much as possible.
It takes no more than 4 minutes to sew one port.
Li Zheng ignored his surroundings and focused on the operation.
Soon, the second port was also anastomosed.
"Loosen the tourniquet and see!" Li Zheng said.
Everyone became excited. Whether the suture would work or not would be known after the blood was released.
The blood pressure in the aorta is no joke. If there is a flaw in the suture, it will be broken by blood in an instant.
The circulating nurse began to unscrew the air pressure valve on the tourniquet, and a hissing sound of air being released was heard.
Except for Li Zheng, everyone else started to get nervous.
The most nervous among them was Bao Youshan, who personally participated in the first vascular transplant operation in our hospital. If it was successful, it would be recorded in the history of our hospital. If it failed, his faith would collapse, and the consequences would be unbearable.
“Squeak…”
The tourniquet continued to reduce pressure, and everyone held their breath, about to witness the arrival of a historic moment.
