Chapter 572 The bubble signal in the brain! (Ask for a monthly ticket! Fight for 2000!)
The First Affiliated Hospital of Kyoto University, cafeteria.

"Eat first, I have something to do!"

Lu Chen stood up abruptly, a gleam flashed in his eyes.

Suddenly, he thought of a potential possibility for that woman's condition!

He didn't even have time to eat, so he was about to leave the cafeteria.

"Lu Chen, where are you going?" Wang Zihao asked immediately.

"Go back to the department!" Lu Chen waved his hand, turned his head and said, "Ke Yue, thank you for your reminder just now, I'm leaving first!"

After finishing speaking, Lu Chen left the cafeteria in a flash, leaving only the three people looking at each other.

……

Back to the department.

Lu Chen immediately came to the ward of the "well-connected family".

At this time, the woman was eating the lunch brought by her family.

Seeing Lu Chen rushing to the ward in a hurry, the woman was slightly taken aback, "Doctor Lu, what are you?"

Lu Chen calmed down a little, and said, "I'm sorry to interrupt your lunch. I have a new idea about your condition."

Hearing Lu Chen's words, the woman immediately put down the chopsticks in her hand, and she couldn't care less about eating.

The migraine afflicted her badly.

Especially this hemianopia and limb sensory impairment scared her half to death!

She is now going to try to take every opportunity to solve her "migraine"!

"Doctor Lu, speak slowly, I'm not in a hurry to eat." The woman looked at Lu Chen and pricked up her ears, not daring to miss a word.

"You may want to do a foam test!" Lu Chen said slowly.

"Foaming test?" The woman was taken aback for a moment, and she looked up a lot of treatments for her condition.

She has dabbled in a lot of knowledge about migraines, brain tumors, etc., and I dare not say that she is a doctor, but at least she can understand related terms, but this time the foaming test proposed by Lu Chen, she is fundamental Never heard of it.

"Because I doubt that you have a problem with your head..." Lu Chen pressed against the woman in front of him tightly, "It's a problem with your heart!"

This sentence made the woman even more confused.

If there is a problem with the heart, how can there be brain performance?

"Listen to my explanation first." Lu Chen continued.

He didn't expect this kind of situation at first, and always thought it was a disease of the nervous system, but after Ke Yue's reminder just now, he suddenly thought of a disease.

"Tell me, I'm listening." The woman was also concentrating at the moment.

Lu Chen said slowly: "A lot of adults, about 1/4, have patent foramen ovale, but most of them are very mild and don't affect their lives. A small number of people will have symptoms."

"The foramen ovale is a physiological channel in the interatrial septum of the heart. It is formed during the embryonic period. This foramen ovale will close soon after birth, but some people do not close it. If it is serious, the blood from the right atrium will flow into it. to the left atrium, and then you have your migraines, your neurological symptoms."

The woman looked at Lu Chen in bewilderment.

She couldn't understand Lu Chen's explanation, because she didn't know the anatomy of the heart at all!
"Let me explain it this way." Lu Chen found a pen and paper and began to draw a picture. He simply drew the four chambers of the heart on the paper. "There are four chambers in the heart. Among them, the left atrium and the right atrium are next to each other but not connected. , because there is a room septum, which separates them, and the foramen ovale is a secret passage between the two rooms. This secret passage is open during the embryonic period, but it will be closed shortly after birth, and the two rooms will not be separated from then on. It's connected."

"Oh, I can understand a bit if you draw pictures like this." The woman is also an intellectual, and she immediately understood what Lu Chen meant, "However, the hole you mentioned is not closed, why does it cause me a headache?"

Lu Chen continued to explain: "Because the foramen ovale is not closed, part of the blood will directly cross the hole and enter the right atrium. This part of the blood will not pass through the lungs, but directly enter the systemic circulation and enter the brain."

"Because this part of the blood does not pass through the lungs, there are often small emboli or small air bubbles, which can directly enter the brain and cause blockage, causing symptoms similar to stroke. This is why you suddenly developed hemianopia and physical impairment last night!"

The woman was stunned for a while, she roughly understood what Lu Chen said, "That is to say, there is a hole in my heart?"

"It can be understood in this way." Lu Chen said, "In fact, this patent foramen ovale is very common, and many people have it, but they are not serious, there are no problems, and they have not been discovered."

"Then how can we find the existence of the breach?"

The woman believed what Lu Chen said, it sounded like that.

In fact, no matter whether Lu Chen can justify himself or not, she will try to believe him.

Because I have never had her illness, I do not understand her pain!
Now, as long as there is even a little bit of hope, she will grab it!
Lu Chen thought for a while, and said: "Some people can see it through cardiac color Doppler ultrasound, but if the patent foramen ovale is relatively small, the heart color Doppler ultrasound may not be able to see it, because the color Doppler ultrasound probe is placed on the chest, and it is still too far away from the heart. , it’s hard to tell.”

"Then what should we do?" the woman asked.

Lu Chen smiled, "Then do a transesophageal cardiac ultrasound, that is, insert the probe from the mouth, all the way deep into the esophagus, and do a color ultrasound in the esophagus, because the esophagus is close to the heart, so you can see it more clearly."

"Wouldn't it be hard to do it through the esophagus?" The woman was a little worried.

"That's right. It's just like doing an ordinary gastroscope. If something goes deep into your esophagus, it will definitely be uncomfortable." Lu Chen nodded slightly. "In addition, in addition to the cardiac ultrasound, the foaming test I just mentioned can also find problems."

The so-called foaming test is to use a tube of normal saline, air, and blood mixed liquid, fully oscillate (two syringes are injected back and forth) to generate bubbles, and then quickly inject it from the vein of the human arm.

Theoretically, after these bubble-filled fluids enter the vein, they will immediately enter the superior vena cava→right atrium→right ventricle→pulmonary artery→pulmonary capillary→pulmonary vein→left atrium→left ventricle→systemic circulation (various arteries, such as the middle cerebral artery) .

If the patient does not have a patent foramen ovale, the liquid filled with air bubbles will enter the pulmonary capillaries according to the above path, and the air bubbles will be absorbed by the capillaries and will not enter the systemic circulation. Therefore, we do transcranial Doppler ultrasound to monitor the brain of the patient. In the middle artery, there will be no traces of air bubbles.

However, if the patient has a patent foramen ovale, and holding the breath during the operation (Valsalva maneuver) can increase the pressure of the right atrium, then the fluid filled with air bubbles will flow directly from the superior vena cava → right atrium → foramen ovale → Left atrium → Left ventricle → Systemic circulation (including middle cerebral artery).

Some air bubbles will pass directly through the foramen ovale to the left heart, and then immediately enter the cerebral artery. At this time, transcranial Doppler ultrasound can detect the signal of the air bubbles, so it can be inferred that there is a patent foramen ovale.

……

Lu Chen immediately brought the woman to the ultrasound examination room to conduct the foaming experiment.

Sure enough, as Lu Chen expected.

After inspection, the bubble signal was found in the woman's brain!

This means that a patent foramen ovale may really exist in a woman's heart.

Hearing the result, the "well-connected" woman was both surprised and delighted.

To my surprise, there was something wrong with my heart, and from what Lu Chen said, it seemed to be congenital heart disease.

The good news is that I finally found the cause of the "migraine"!
