Chapter 415 Pterional Craniotomy

Chapter 418 Pterional Craniotomy

"Professor Zhihe, where are you taking me?" Qin Feng asked suspiciously.

"I'll take you to see a patient with an aneurysm. You will be the chief surgeon for this patient. If it succeeds, Mr. Kudo's operation will be handed over to you." Dr. Zhihe said.

This is to protect Mr. Kudo. Although Qin Feng is favored by Mr. Kudo, the Department of Surgery does not know how good Qin Feng is. Surgery is the best way to prove a doctor.

As for the patient, just change to another surgeon, and the hospital will casually brag about Qin Feng's status as a returnee, and the patient will not doubt it.

After taking a look at the patient, the patient seemed very happy, and did not despise Qin Feng because he was a young man, but was a little excited.

The main reason is the cherry blossom country's medical system, so that patients will not doubt the hospital's choice at all.

After all, the second most popular profession in Sakura Country is lawyer, and any disagreement will result in a lawsuit.

Back in the department, Qu Ping leaned over after sorting out the cases.

"Doctor Qin, are you going to the operating room later?" Qu Ping asked.

"How do you know?" Qin Feng wondered.

Today's operation was decided temporarily, how did Qu Ping know so quickly?

"I heard some doctors over there discussing you. I thought they were talking bad about you. I didn't expect that Professor Zhihe would personally help you. Doctor Qin, you are so awesome." Qu Ping gave a thumbs up.

This is equivalent to a director-level doctor helping Qin Feng, and he is still in a foreign country, Qin Feng is a trainee.

If you say it, I am afraid that few people will believe it.

"You also want to go to the viewing platform?" Qin Feng understood what Qu Ping meant.

"That's right, I want to go in and have a look, either the second or the third assistant." Qu Ping smiled.

"Okay, let me tell Professor Zhihe, Shen Yue, do you want to go in and watch the platform?" Qin Feng asked.

Qu Ping looked at Shen Yue's face with a bit of displeasure. He had been in a relationship with Qin Feng all this time. As for Shen Yue, who usually put on a cold face, could it be that Doctor Qin is interested in Shen Yue?
Obviously, Qu Ping misunderstood Qin Feng. Qin Feng just thought that it is best to help each other and study together in a foreign country.

Everyone will return to the country to benefit the people in the end, but Qin Feng hopes that they can learn more.

"Can I?"

"Yes." Qin Feng smiled.

Shen Yue felt her heart thumping, this was the first time she was taken care of by her peers.

In the past, Shen Yue was a top student ever since she was a student. She always had a cold face and was the kind who didn't get close to strangers.

He is a bit rebellious in dealing with people, and he is a bit aggressive in speaking.

Once, she also liked a boy, but the two hadn't developed well, and they parted ways because of the results of the college entrance examination, and they couldn't get in touch with each other ever since.

After entering the university, she was favored by her tutor and walked ahead of her peers like stars all the way. At that time, she made up her mind to enter the best hospital in the country and become the most powerful doctor.

Once a person has a goal in his heart, love will become a stumbling block on the road.

The man who has the most contact with Shen Yue is probably Teacher General.

Shen Yue blushed and glanced at Qin Feng, then followed Qin Feng to the operating room.

Qu Ping kept looking at Shen Yue and Qin Feng, always feeling that they had some ulterior secret.

When Professor Zhihe learned that Qin Feng was going to bring his friends to watch the stage, he immediately agreed.

It's just that this surgery is quite special, so it's not open to the public, only Shen Yue and Qu Ping can watch it.

Qu Ping was more clever, and asked for a second assistant position, which was more advantageous than Shen Yue watching from the sidelines, and he could see more clearly.

"Is it ready for surgery?" Doctor Zhihe asked after getting dressed.

"Okay."

Qin Feng just went to the training room to try several MCA aneurysm surgeries, and the feeling is still good.

MCA is to judge the location of the aneurysm through interventional angiography, and then perform the corresponding craniotomy.

The whole operation is issued from the internal carotid artery, which can be divided into four segments: M1 sphenoid segment, M2 insular segment, M3 insular opercular segment, and M4 cortical segment.

Doctor Zhihe looked at Qin Feng in surprise, MCA aneurysm surgery is the best surgical plan, but when the MCA is dissected during craniotomy, the length of the M1 butterfly segment will have a great impact on the surgery.

If it is too short, the anatomical position will be deepened and the complexity of the operation will be increased, but if it is too long, there will be a risk of intraoperative injury.

And there are some important branches in the M1 segment, the lateral lenticulostriate artery and the anterior temporal artery, which often originate on different sides of the M1, and if they are accidentally blocked, serious consequences will result.

"Are you sure?"

"determine."

Doctor Zhihe didn't continue to say anything, but quietly watched Qin Feng's operation.

Qin Feng put the patient in a supine position with the neck hyperextended and the head turned 30 degrees to the opposite side so that the Sylvian fissure was perpendicular to the ground.

A pterary point was quickly made around the sphenoid bone, the exposed superficial temporal artery was preserved, and the lateral part of the sphenoid bone was resected.

As soon as the operation started, Qin Feng's speed became extremely fast.

From the top of the Sylvian fissure, along the M2 frontal branch to the M1 segment, the blood supply is controlled proximally to prevent massive bleeding.

If the proximal control is used, it can also ensure the full display of the surgical field.

After M1 and M2 are fully exposed, Qin Feng's next step is to expose the aneurysm neck, but when separating the aneurysm, it needs to be blocked to soften the aneurysm neck.

Qin Feng blocked the proximal end of M1 for 5 minutes each time, then released it for 2 minutes, and repeated the above actions to facilitate separation.

Fortunately, the patient is a young man. If it were an old man, Qin Feng would not dare to do this.

Because elderly patients are prone to atherosclerosis, the proximal part of M1 cannot be selected as the blocking site.

After blocking, Qin Feng found the hidden temporal trunk, and then separated it from the neck of the tumor.

The separation is also very simple, that is, bipolar electrocoagulation shaping, which can shrink the tumor capsule, and then allow Qin Feng to better observe the situation around the tumor neck.

After the separation, Qin Feng asked Dr. Zhihe to use a Doppler flow microprobe to find places with low proximal flow.

Then clip the neck of the aneurysm parallel to the M2 plane and perpendicular to the M1 plane. After clipping, Qin Feng carefully checked the tip of the clip and found that the blood vessel branches and perforating arteries were not wrongly clipped.

Then the resection is performed, and the entire operation is concluded.

It took a total of two and a half hours, and Qin Feng asked the equipment nurse to wipe his sweat.

"This patient is a little more serious than that mathematician." Qin Feng said.

Qu Ping was dumbfounded. The second assistant was on-hook throughout the whole process. Qin Feng didn't use his brain to pull at all, and even the first assistant was on-hook throughout the whole process except for using a few equipment.

"Qin Sang, you are right. This patient is more serious than Mr. Kudo, so it is also a test for us. The results are obvious. You are definitely qualified to operate on Mr. Kudo." Dr. Shiwa was completely convinced.

Although it was an MCA aneurysm operation, Qin Feng did not use conventional surgical techniques, but the most difficult pterional craniotomy.

Although Dr. Zhihe can also operate on aneurysms, compared with Qin Feng, his skills are like rubbish.
