Thursday morning, Lin Jie's office at the University Hospital.

After reading Lu Donghai's latest inspection and laboratory data, Lin Jie felt a little big.

The latest cranial CT scan showed that only two of the clots in Lu Donghai's skull were barely recognizable, and the size was much smaller than before, and the other clots were either completely dissipated or so small that they could not be displayed.

That's a good sign.

However, the conclusion of the test done by the brain surgery department on Lu Donghai was that the cranial memory control center and logical thinking center were damaged.

Lin Jie also did not find any signs of a brain tumor, which made him rule out the other biggest possibility.

Lu Donghai's other test data, the most abnormal data is the blood lipid concentration, plasma total cholesterol concentration, more than 6.5, which is too high.

He was also tested for high blood pressure, mild liver damage, kidney damage, and moderate fatty liver disease.

Considering Lu Donghai's overly obese body, this blood lipid concentration, high blood pressure, and fatty liver are all understandable, coupled with his previous experience in boxing, it is not surprising that he has liver and kidney damage.

It's just that the damage to this memory control center and logical thinking center makes Lin Jie a little difficult to explain.

If after being injured, Lu Donghai will soon become stupid, Lin Jie understands very well that the clot produced by the injury or the head injury caused by external heavy blows.

But from the description of the patient's family, Lu Donghai's forgetfulness and stupidity are gradually aggravated.

Now, more than a year later, the symptoms continue to worsen.

Lin Jie analyzed the data from the patient's examination data and found that Lu Donghai's craniocerebral injury should be gradually recovering, rather than showing gradual aggravation.

What is the reason for this?

Lin Jie came to the viewing lamp and watched Lu Donghai's craniocerebral arteriovenous imaging.

Strips of blood vessels of different thicknesses and twists are shown on the film in the form of gray bars.

He found no signs of blockage in the blood vessels.

Lin Jie hugged his arms, held his chin, quickly filtered Lu Donghai's various examination data in his mind, and thought about the cause......

Time passed minute by minute, Lin Jie still got nothing, and his brain hurt a little when he thought about it.

"Sister Lan Ruo, do you have any insight?"

As a last resort, Lin Jie sought advice from a master.

Shen Lanruo whispered in Lin Jie's mind: "Lin Jie, in terms of head injury, what I know now is no longer as good as you, don't forget that you have absorbed the knowledge of Dr. Sisrda." ”

"You know this more comprehensively and clearly than I know. ”

"Still, I can give you a way to think about it. ”

Lin Jie asked with great interest: "Sister Lan Ruo, what is the way to think?"

"When you're faced with too much information to make an effective decision, go back to the root and get back to the beginning of the problem. ”

Shen Lanruo said slowly: "This big fat man's head injury started from the injury he suffered in that boxing. Let's take a closer look at the source. ”

Feeling that what Shen Lanruo said was very reasonable, Lin Jie took off all the CT and angiography maps made by the middle few examinations on the film lamp, leaving only the first CT and angiography charts that were done at the beginning, as well as the latest CT maps and angiography charts.

On the first CT scan, there were more than a dozen clots scattered around......

Looking at the seemingly chaotic blood clots, Lin Jie's heart suddenly moved.

He took off a CT scan and carefully overlaid it on the angiography to see the specific distribution of more than a dozen clots.

There were several clotted blood clots in their locations, which caught Lin Jie's attention.

Arteriovenous angiography of the brain, due to technical limitations, does not show too small blood vessels.

These clots are located at the ends of several small blood vessels that appear to be absent on the contrast of small blood vessels.

And the location here is precisely the memory control center of the cranium, as well as the logical thinking center.

Thinking of Lu Donghai's seriously high blood lipid concentration, Lin Jie's face gradually overflowed with a smile, and said with a smile: "Sister Lan Ruo, I think I have found the cause." ”

"Oh, so soon? Listen, I'll judge if it makes sense. ”

Shen Lanruo's tone was slightly questioning.

Lin Jie pointed to several overlapping CT and angiography maps, and analyzed: "Sister Lan Ruo, you see, the existence of these clotted clots should have compressed these tiny arteries. ”

"The arterial vessels are compressed, and the blood flow rate will definitely be severely affected. Moreover, after Lu Donghai was injured, his weight increased sharply, and his blood lipid concentration also rose sharply. ”

"High blood lipids, combined with a sudden drop in blood flow rate, obviously bring a dangerous risk of blood vessel congestion......

Lin Jie continued to analyze: "With the passage of time, the clots in these places, although gradually decreasing, even disappeared. ”

"However, the blood vessels in these places should have been congested, and even without the compression of blood clots, the blood flow rate in these places is still maintained at a low level. ”

"High blood lipids, slow blood flow, and increasing congestion create a vicious circle. ”

"The memory control center and logical thinking center here have to slowly reduce their own activity because the supply of oxygen and nutrients they receive is gradually decreasing, which causes Lu Donghai's external symptoms to become more and more serious and appear more and more stupid. ”

Lin Jie said with a smile: "It's just that the blood vessels in these places are too thin to be shown on the imaging map, and even if there is some congestion, we can't find it." ”

"Sister Lan Ruo, what do you think of my inference?"

After a pause, Shen Lanruo's voice sounded and praised: "It is a very probable inference, I think, you have really found the cause." ”

"If you want to verify it, it's relatively simple, just inject a contrast agent and observe the difference in blood flow rate between the blood flowing through the cranial memory and logical thinking centers and the blood flow rate in other places. ”

Lin Jie exhaled softly, looked at the time, and suddenly realized that it was almost twelve o'clock at noon.

Thinking that there was still class at one o'clock in the afternoon, Lin Jie hurriedly cleaned up and left the office......

After getting out of the elevator, Lin Jie thought about it, took out his mobile phone, and made a call to Lu Kaicheng.

After the phone was connected, Lin Jie inquired and learned that after Lu Kaicheng did not book surgery in the afternoon, he told him about Lu Donghai's condition and his own speculation.

He then advised: "Doctor Lu, please test it, and if my speculation is true, I will give him interventional surgery and inject thrombolytic agents to relieve blood vessel congestion." ”

Lu Kaicheng seriously promised: "Okay, Lin Jie, you can go to class with peace of mind, I will deal with this patient." ”

The reason why Lin Jie was in such a hurry to ask Lu Kaicheng to do it for him, instead of letting the patient wait until after class and then deal with it himself.

One is because the earlier the treatment, the less dangerous Lu Donghai is.

Judging from Lu Donghai's current symptoms of stupidity, the congestion of his blood vessels is already quite serious, it can be said that this guy is in danger of being completely blocked at any time and has a cerebral infarction.

It is often said that so-and-so speaks evilly, and what he says comes from what he says.

Lin Jie didn't want to be during his lecture, Lu Donghai really had a cerebral infarction, causing irreversible consequences.

The second reason is that, if it is really the cause of this cause as Lin Jie speculated, the treatment method is relatively simple.

It is only necessary to be treated through cerebrovascular interventional surgery, and thrombolytic agents are injected in appropriate places to ablate fat deposits and other substances attached to the blood vessel walls to dredge congestion.

Of course, this operation also requires a certain amount of technical content, but with Lu Kaicheng's current ability, it is enough to deal with it.

After hanging up the phone, Lin Jie got into the car, drove out of the hospital, and drove quickly towards the medical school.

Lin Jie bought some food casually on the road, drove while eating, and then rushed to the place where the class was, the small hall of the medical school, at one o'clock.

After half a month, Lin Jie attended the class again, and the small auditorium that can accommodate 500 people, with nearly 200 people coming to listen to the class.

Lin Jie put on the small microphone and said, "Okay, let's start the class." ”

"In this lesson, we will continue to talk about ......"

"Expert Lin, excuse me, can I ask a question?"

A sudden voice interrupted Lin Jie's words very unceremoniously.
