The look in Senior Brother Cao's words was quite sincere, not modest, as if he had forgotten to deal with her dimensionality reduction. 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, "Let's chat while eating. Thank you, doctor, for speaking slowly. Don't be nervous."
Xie Wanying took a deep breath when her boss noticed the pressure on her heart.
Continuing the conversation while eating can unconsciously reduce her speaking pressure.
Cao Yong took his chopsticks and put a piece of beef in her bowl, and said, "Let's start with what you find interesting."
Speaking of her points of interest, the first one that bears the brunt must be the top-notch acrobatic skill that Senior Brother Cao showed in front of her.
"I'm sure it's not an aneurysm. I thought about it later. Senior Brother Cao should have used his hand feel to figure out the most accurate pressure value for the blood flow in that part of the patient. He slowed down the speed of creating the contrast agent to match the patient's own blood flow speed and grasped it.
The precise timing of the angiography resulted in a completely different result." Xie Wanying expressed her thoughts on the post-operative brain scan.
Regarding her point of view, Song Xuelin took the lead in nodding. He had the same idea as Dr. Xie.
This was something his brain couldn't figure out even if he tried to figure it out.
He didn't expect that there would be a network of small blood vessels plus a larger blood vessel.
Let’s talk about the shortcomings of interventional surgery. Many doctors often have a hand problem. The catheter in their hand has always been like a boat drifting along the water. It goes wherever it goes smoothly. Like the last cardiovascular surgery, there are
The doctor almost had a serious accident because the catheter was too smooth and the catheter slipped into the branch blood vessel by itself.
In the same way, the microcatheter in Song Xuelin's hand entered the large blood vessel unobstructed. He thought there was only one blood vessel there, but he failed to feel that there were actually a lot of branches running out in all directions. He didn't think much about creating the contrast agent. All of a sudden
If you push it further, the pressure will definitely double, and the small blood vessels will be fully penetrated and filled with contrast agent, turning into overlapping images, like an aneurysm. The correct way is to have the subtle feeling that Cao Yong's terrifying hands can detect. According to what Xie Wanying said
Accurate results can be obtained by grasping the correct speed and correct timing.
In a word, it’s too difficult. These things cannot be predicted by doctors before surgery just using their brains. It is precisely because of these unexpected situations that often occur during surgery that doctors can’t grasp their heads. That’s why it is said that every surgery carries risks.
Doctors need to inform patients in advance that no surgery is completely risk-free.
As soon as the conversation started, Xie Wanying continued to talk tirelessly, but she was an academic stickler, and she couldn't stop talking about academics: "Then Senior Brother Cao accurately touched the location of the anterior choroidal artery. I thought about that artery afterwards.
The opening of the eye should be a blood flow conflicting area at a certain angle with the opening of the ophthalmic artery, so its blood flow fluctuations can affect the blood flow direction inside the ophthalmic artery."
The waiter came in with the second plate of dishes and found that the place was extremely quiet. He listened curiously and was sure that he could not understand the inscrutable words of the doctors. He quickly put the dishes on the table and carefully exited.
"Why does its blood flow fluctuation have such a large impact on the ophthalmic artery? It is probably necessary to estimate its diameter." Xie Wanying said, immersed in her own thoughts.
Like everyone else, they didn't notice that the second dish was already on the table, so they rested their chopsticks and recalled the surgery scene with her.
