Senior Cao’s words and gaze were sincere, not humble, as if he had forgotten his Dimensional Strike on her. Xie Wanying was at a loss whether to cry or laugh.

The waiter came over and served the first cold dish.

Zhai Yunsheng urged everyone to pick up their chopsticks and said, "Let’s eat and chat. Dr. Xie, take your time, no need to be nervous."

The boss noticed the pressure in her heart, and Xie Wanying took a deep breath.

Eating while continuing the conversation indeed relieved much of her speaking pressure without her noticing.

Cao Yong took his chopsticks and placed a piece of beef in her bowl, saying, "Start from the point you’re interested in."

Speaking of her point of interest, it was inevitably the first-hand ultimate skill that Senior Cao displayed in front of her, which could be regarded as top-level acrobatics.

"It’s definitely not the aneurysm one. After thinking about it, I believe Senior Cao relied on his sense of touch to grasp the correct blood flow pressure at that location in the patient. He slowed down the speed of the contrast agent to match the patient’s blood flow speed, capturing the accurate moment for angiography, thus achieving a completely different result," Xie Wanying stated her post-operative conjecture.

Song Xueling was the first to nod at her viewpoint. He shared the same thoughts with Dr. Xie.

It was something his brain couldn’t calculate at all.

He didn’t anticipate that the place would be a small vascular network with a larger vessel added in.

This brings up the drawbacks of interventional surgery. Many doctors often make mistakes due to their sense of touch. The catheter in their hand, while cruising through the vessel, drifts like a boat downstream, going wherever it’s smooth. Just like in last time’s cardiovascular surgery, a doctor faced a near-big incident because the catheter slid too smoothly into a branch vessel.

Similarly, the microcatheter in Song Xueling’s hand entered the large vessel effortlessly, mistakenly assuming there was only one vessel there, failing to feel that, in actuality, there were numerous branching paths emerging. He paid no extra thought while injecting the contrast agent; pushing it down all at once definitely increased the pressure, filling the small vessels with contrast agent, creating overlapping images resembling an aneurysm. The correct approach is to have Cao Yong’s terrifyingly sensitive hands to detect the subtlety, as Xie Wanying mentioned, grasping the speed and timing to achieve accurate results.

In short, it’s very hard for doctors to predict such events preoperatively just using their brain. During surgery is often when these unexpected situations that leave doctors puzzled occur, highlighting the fact that each surgery carries risks, and doctors need to inform patients in advance. There’s no such thing as a completely risk-free surgery in the world.

Once the conversation started, Xie Wanying spoke tirelessly, being an academic enthusiast herself, unable to stop when talking about academics: "Later on, Senior Cao accurately pinpointed the location of the anterior choroidal artery. Reflecting afterward, the opening of that artery should have a blood flow impact zone at a certain angle with the opening of the ophthalmic artery, so its blood flow fluctuation could influence the internal blood flow direction of the ophthalmic artery."

The waiter brought in the second dish and found the place overly quiet, curiously eavesdropping but unable to comprehend the profound conversation of the doctors. Quickly placing the dish on the table, he carefully withdrew.

"Why does this blood flow fluctuation have a significant impact on the ophthalmic artery? I probably need to estimate its diameter," Xie Wanying immersed herself in her thoughts.

Everyone else was the same, not noticing that the second dish had already been served, putting down their chopsticks to recall the surgical scenes with her.
