Chapter 2105 [2105] Pointing Out the Disadvantages
Senior Brother Cao's words and eyes were very sincere, and he didn't seem to be humble. He seemed to have forgotten the blow to her. Xie Wanying couldn't laugh or cry.
The waiter came over and served the first cold dish.
Zhai Yunsheng called on everyone to pick up their chopsticks and said, "Talk while eating. Doctor Xie, please speak slowly, don't be nervous."
Seeing the pressure in her heart, Xie Wanying took a deep breath.
Continuing to talk while eating can unknowingly reduce her a lot of talking pressure.
Cao Yong picked up a piece of beef in her bowl with chopsticks, and said, "Start with what you find interesting."
Speaking of her interests, the first thing that bears the brunt must be the nirvana of top acrobatics that Senior Brother Cao showed in front of her for the first time.
"It's definitely not the one with the aneurysm. I thought about it later. Senior Brother Cao should rely on the feel to grasp the most correct pressure value of the blood flow in the patient's part, and slow down the speed of creating the contrast medium to match the patient's own blood flow speed. The exact timing of the angiography resulted in a completely different result." Xie Wanying shared her thoughts on resuming after brain surgery.
Regarding her point of view, Song Xuelin nodded first. He had the same idea as Dr. Xie.
This was beyond his brain's ability to figure it out.
He didn't expect that there would be a network of small blood vessels plus a larger blood vessel.
This is about the disadvantages of interventional surgery. Many doctors often suffer from hand feeling problems. The catheter in the hand is like a boat drifting along the water when it goes in the blood vessel, going where it goes smoothly. Like the last cardiovascular surgery, some doctors almost had a major accident because the catheter slipped into the branch blood vessel because the catheter was too smooth.
In the same way, the microcatheter in Song Xuelin's hand entered the large blood vessel unimpeded. He thought that there was only one blood vessel there, but he didn't feel that there were actually a bunch of branches extending in all directions. He didn't think too much about creating the contrast agent. Pushing it all at once would definitely increase the pressure, and the small blood vessels would be filled with contrast agent, forming multiple overlapping images, like an aneurysm. The correct way to do it is to have the subtle sense of Cao Yong's terrifying hands. Only by grasping the speed and timing as Xie Wanying said can we get accurate results.
In a word, it's too difficult. These things can't be predicted by the preoperative doctor's brain alone. It is precisely these unexpected situations that often confuse the doctor during the operation, so it is said that every operation is risky, and the doctor needs to inform the patient in advance. There is no completely risk-free surgery in the world.
As soon as the chat box was opened, Xie Wanying continued to talk tirelessly. Who made her an academically stubborn person, and she couldn't stop talking about academics: "Afterwards, Senior Brother Cao accurately located the anterior choroidal artery. I recalled afterwards that the artery The opening of the ophthalmic artery should be a blood flow hedge area at a certain angle with the opening of the ophthalmic artery, so its blood flow fluctuations can affect the direction of blood flow inside the ophthalmic artery."
The waiter came in with the second plate of dishes, and found that the place was too quiet, so he listened curiously, making sure that he couldn't understand the inscrutable words of the doctors at all. Quickly put the dishes on the table and exit carefully.
"Why does its blood flow fluctuation have a greater impact on the ophthalmic artery? It is estimated that its diameter needs to be estimated." Xie Wanying said immersed in her own thoughts.
Like the others, they didn't realize that the second course had been served, so they rested their chopsticks and recalled the operation scene with her.
