"Why have you been there for so long?" Li Shangai raised his head and looked at Yi Shengdao.

Yi Sheng glanced at Meng Xianyang and said, "The spare white coats have been taken to be cleaned, so I went to the emergency department to borrow one." ”

"Ah, that's Professor Li. Meng Xianyang explained: "A few days ago, there was a case of suspected H7N9 in the neurosurgery department, so I asked the nurse to send it to the sterilization supply center. ”

"Hmm. Li Shangai glanced at Meng Xianyang, he understood that this must be a good thing done by Meng Xianyang, it seems that he will not have a good time when he first came to the Affiliated Hospital of Nanyao Medical College.

Taking the white coat in Yi Sheng's hand, a smell of sweat came from the white coat, and Li Shangai frowned.

He has a slight cleanliness habit, but now he only has this white coat, and he has to see the patient later, so Li Shangai can only wear it.

"Professor Li, now let's go and see the patient. Meng Xianyang proposed.

Li Shangai put down the CT image in his hand, turned his head and handed the medical record to Yi Sheng, "Yi Sheng, you can also take a look." ”

The three of them walked in the spacious corridor of the third ward of neurosurgery, and Yi Sheng habitually opened the medical record book and looked at the information recorded on it.

Medical records are the most intuitive reflection of a patient's condition changes. All the information including imaging data, laboratory data, case analysis, etc., will be summarized in this small medical notebook.

The patient's name is Liang Susu, 16 years old, who attends Nanyao No. 1 Middle School and has just entered his first year of high school this year. Such a twenty-eight-year-old girl should have enjoyed a carefree life that should have belonged to her schoolwork, but illness took it all away.

"Professor Li, this is the patient's ward. The patient himself does not know about the condition yet, so Professor Li will not mention the relevant topic for a while. Meng Xianyang reminded in a whisper at the door now.

Through the narrow glass window of the ward, Yi Sheng saw the little girl lying on the hospital bed with her eyes closed, and next to her sat a gray-haired middle-aged woman with a knife in her hand and peeling an apple.

Meng Xianyang cautiously pushed open the door, the middle-aged woman raised her head, and Yi Sheng saw a pair of bloodshot red and swollen eyes, and there were unwiped tears in the corners of her eyes.

"Director Meng, are you here?" The middle-aged woman hurriedly put down the knife in her hand, stood up and wiped her eyes, and said, "Su Su just fell asleep, do you need me to wake her up?"

"The child finally fell asleep, so let her sleep more. Meng Xianyang lowered his head and gently put Liang Susu's outstretched foot back into the quilt, and then tucked the corner of the quilt again.

"This is Professor Li Shangai from the National Medical University, Professor Li is very accomplished in intracranial tumors, and I believe that Professor Li can give a better surgical treatment plan. Meng Xianyang introduced to the middle-aged woman.

"Professor Li, this is Liang Susu's mother, Ms. Pan Yun, if you have any questions, just ask her, I still have something to do, so I'll be busy first. After speaking, Meng Xianyang nodded at the middle-aged woman and left the ward.

"Professor Li, let's go out and talk. Glancing at his sleeping daughter, Pan Yun said to Li Shangai.

The moment the ward door closed, Pan Yun leaned against the ward door, and the afterglow of his eyes swept to the sleeping Liang Susu from time to time.

"How is Su Su's spirit these days?" asked Li Shangai.

"It's not good, Su Su can't sleep these days, and she often says that she is very dizzy, and she is always nauseous, she can't drink the porridge I bought for her, and then Director Meng prescribed some medicine to improve a little, but when the medicine passed, she began to feel uncomfortable again. Pan Yun's eyes were full of worry and said, "I have been by her side for the past few days, for fear that something will happen to her at night." Professor Li: I heard Director Meng say that you can cure Susu's disease, is it true?"

"Ms. Pan Yun, don't get excited. In this way, I will give you a brief introduction to your daughter's situation first," Li Shangai took out an MRI image from the medical record book in Yi Sheng's hand and pointed at it: "Your daughter's MRI image shows a large round long T1 and long T2 signal shadow in the brain stem, and the FLATA image is slightly higher in the signal with a clear boundary. 34 ventricles are compressed. Both ventricles are symmetrical, slightly dilated. There was no displacement of the midline structure, and no obvious abnormalities were seen in the sulcal fissures of both cerebral hemispheres. This indicates that the tumor shows no signs of spreading. ”

Except for the last sentence, Li Shangai's sentence is all for Yi Sheng, and it is difficult for ordinary people who have not undergone systematic learning to understand the meaning represented by "long T1 long T2 signal shadow", let alone understand the MRI image.

However, Yi Sheng couldn't understand it, but he was too embarrassed to ask, so he could only stand aside and pretend to understand and nodded.

Chicks like Yi Sheng, who have just come out of medical school, can basically only understand CT images, after all, CT images talk about density, and the description of a lesion has high density, equal density, low density or mixed density. The bone density is the highest, and it appears white on CT imaging. The density of water and air is low, and the CT image is black. Just remember that a normal CT image can detect the difference in color, and the diagnosis can be made.

However, MRI images are different, they are more complex than CT, and they don't talk about density and signal. There are 5 kinds of signal sequences in the MRI image, and the most basic NMR image is the T1WI and T2WI sequences, and each tissue behaves differently in these two different sequences.

Let's take water as an example, the water is low on the T1WI and looks black. But on T2WI it is bright and white.

When diagnosing, it is necessary to combine and carefully analyze different signal sequences to reach the final conclusion, so the MRI image is not easy to understand without three or five years of effort.

"The size of the tumor is about 40X30X40mm, most of it has a boundary with the surrounding normal tissue, a small part of the boundary is not clear, the enhancement is not obvious when enhanced, the tumor has no signs of spreading for the time being, it should be just a simple focal endogenous brainstem glioma, which does not involve the spine and the grade is very low, although the tumor tissue is not obtained for pathological analysis, but the possibility of recurrence after surgery will be very low. Lee Sang-ae explained.

"However," Li Shangai changed his words, which made Pan Yun's heart that he had just put down hang again, "This operation is very risky. ”

"We can see that this tumor is really big," Li Shangai stretched out his thumb and gestured: "The size of the brainstem is about the same size as my thumb, and the brainstem is composed of three parts: the medulla, the pons, and the midbrain from bottom to top, and it is densely covered with important nerve centers such as heartbeat and breathing, as well as extremely tiny blood vessels." This tumour straddles the medulla oblongata and the pons, and the nerves and blood vessels on it may be lost if you are not careful during surgery. If the nerve is damaged, there is a good chance that your daughter will die during the procedure. ”

Although Lee Sang-ai is an expert in the field of neurosurgery at the National Medical University, since he became a professor at the International Medical University, he has rarely performed surgery himself, and has conducted more theoretical research. And as he grew older, his physical strength also decreased dramatically, and for such an operation, he was really not sure enough to ensure that the operation would be successful.

There was a sudden sound in the ward, Pan Yun hurriedly ran in, and Li Shangai and Yi Sheng also followed.

"Mom, I'm so uncomfortable. A weak and hoarse voice came out of Liang Susu's mouth.

"Su Su is good, you won't feel bad when the nurse sister gives you a drip. Pan Yun gently stroked Liang Susu's forehead and comforted.

Mother and daughter connected hearts, looking at Liang Susu's uncomfortable appearance, Pan Yun was also very uncomfortable, and tears couldn't help but flow.

Pan Yun turned around and knelt down slowly to face Li Shangai, and pleaded: "Professor Li, I know that you must have a way to cure Susu, please save Susu, I only have such a daughter, please, please, please....."

Speaking of the back, Pan Yun couldn't cry anymore, Yi Sheng hurriedly walked over and helped Pan Yun up and said, "Auntie, don't worry, we will definitely do our best to cure your daughter!"

Li Shangai sighed, looked at Liang Susu on the hospital bed and Pan Yun on the side thought for a long time before slowly speaking: "Let your daughter rest more in the past few days, and I will work out the surgical treatment plan as soon as possible, and strive to perform the operation within a week." ”
