Chapter 1970: : You taught me!

Surgery is never cold.
　　 but emotional.
　　Because the purpose of surgery is to cure, not only cure diseases, but also cure people's hearts and hope.
　　 In the ward at this time, Zhao Zhuang was crying and could not speak.
　　Who is San Yutang?
　　 It is no exaggeration to say that a word from General Chang can determine the fate of Zhao Zhuang.
　　 To be honest, does he regret it?
　　Because he jumped into the river to save people, his life or death was uncertain, and he was even disabled for life.
　　 Zhao Zhuang admitted that he really regretted it!
　　 But... Regret is regret. Many times, even if you regret it, you might still do it at that time!
　　 Zhao Zhuang doesn't feel that he has done something wrong, but he just feels... that he is not worthy of such a good girl.
　　 But!
　　 Looking at the ring on his ring finger, Zhao Zhuang had mixed feelings in his heart.
　　Perhaps people really want to protect someone for a lifetime, right?
　　 Looking at Yang Na, Zhao Zhuang felt that if he was sorry for this girl in this life, it would be the biggest mistake.
　　Chen Cang glanced at Yang Na with a smile, then looked at Zhao Zhuang, and couldn't help saying: "What a wonderful girl, you can't just let it down!"
　　At this time, Zhao Zhuang's parents walked in.
　　 First looking at Zhao Zhuang, the old couple's heart is really complicated.
　　 The old couple are both old farmers. Although they are enthusiastic on weekdays, they don't necessarily dare to do such self-sacrificing things.
　　Although they are very proud of their children's behavior, they are most worried and perturbed.
　　 They don’t want their children to be heroes, they hope he can be an ordinary person.
　　 Zhao Zhuang’s mother kept crying.
　　At this time, Chang Yutang walked over and shook hands with the two of them and said seriously: "Brother, sister-in-law, you have given birth to a good son!"
　　 "Don't worry, the country will treat him for his illness, find the best doctor, and use the best means to treat him!"
　　 Hearing what San Yutang said, the two of them breathed a sigh of relief.
　　 As parents, there is light on their faces, but what they want more is the happiness of their children.
"This is Professor Chen Cang. Since Professor Chen is sure, you can rest assured." Chang Yutang introduced Chen Cang to each other. "Professor Chen is the world's top surgeon and the deputy head of our National Central Health Commission! "
　　 "I'm not afraid of your jokes. I don't deserve Professor Chen to be my health doctor. This is the health doctor of the national leader. You can rest assured with him!"
　　 Actually, San Yutang said these things in hopes that the other party would be relieved.
　　 Although these words sound exaggerated, they are very useful to the common people!
　　 As expected, the two looked at Chen Cang, and Zhao Zhuang’s mother said with some expectation and excitement: "Professor Chen, please, save my son."

　　 After Chen Cang left the ward, Geng Hongming followed Chen Cang to the doctor's office.
　　 Lao Ma is close behind!
　　 Entering the office, Lao Ma couldn't help but said, "Cang, can you really do a femoral head necrosis operation?"
　　 Although Geng Hongming didn't speak, the meaning in his eyes was very clear, showing some suspicion.
　　 can't blame them
　　Because avascular necrosis of the femoral head has always been an international problem.
　　 Chen Cang looked at Lao Ma seriously, and seemed a little curious and said: "Isn't this what you taught me?"
　　 The old horse was dumbfounded when he heard it!
　　 Lao Ma looked at Chen Cang in disbelief, wondering what kind of medicine this guy sold in the gourd today?
　　 But Geng Hongming is also blinded!
　　 What the is this?
　　 He couldn't help turning around and looking at Ma Yuehui.
　　 Lao Ma suddenly coughed and laughed: "Oh? I taught it, cough... You see, I forgot it myself!"
　　 Chen Cang picked up his eyelids, this guy is really shameless!
　　 At this time, the doctor in charge took the other party's film.
　　 There are X-films and nuclear magnetic films.
　　 Generally, it is very difficult to diagnose femoral head necrosis early.
　　Because the bone quality has not changed, let alone x-rays for osteoporosis, even radionuclide scans can’t detect it.
　　 However, MRI can distinguish between osteochondral and bone marrow by showing low, medium and high signals respectively. Therefore, it is generally believed that MRI　　 is one of the best methods for early diagnosis of femoral head necrosis.
　　 However, when Chen Cang saw the film, his eyes suddenly brightened!
Generally speaking, at the beginning of the disease, only a single major blood vessel may be damaged, but as the disease progresses, the residual circulating blood volume is not enough to maintain the normal blood supply of bone cells in the damaged area, and the bone marrow tissue will be damaged first , And then osteonecrosis occurred.
　　 This is also the reason why trauma is easier, because during trauma, the blood vessels in the femoral head area are directly damaged, and they are also provided for blood supply.
　　 At this time, Chen Cang discovered that the signal of the patient’s femoral head, including bone marrow, was not uniform!
This incidates that……
　　 At present, the femoral head is not due to necrosis due to a large amount of ischemia. If you are rescued now, it may be too late!
　　 Thinking of this, Chen Cang said directly to Geng Hongming: "Director Geng, I suggest surgery immediately!"
　　 Geng Hongming was taken aback, and then asked: "Why?"
　　 If Chen Cang can't persuade him, it is impossible for Geng Hongming to agree.
　　He is the director, he is responsible for the patient!
　　 can't just obey because the other party is famous.
　　Chen Cang explained: "The patient should have a drill hole decompression last night to reduce the intraosseous pressure in a timely manner, and promote venous return.
　　 While relieving the nourishing vasospasm, I suspect that the new blood vessels can grow into the ischemic area along the bone hole. "
　　 "So so far, the femoral head has not undergone significant ischemic changes. At this time, if bone transplantation is performed, it can actually improve the deficiency caused by femoral head injury!"
　　 Geng Hongming's eyes lit up when he heard the bone transplantation, but then frowned, "Femoral skull transplantation?"
　　Chen Cang nodded: "Yes, this may be the only way."
After hearing this, Geng Hongming was a little worried. Femoral head transplantation... it sounds simple, but it is actually a big project, including cancellous bone transplantation, cortical bone transplantation, muscular pedicle bone transplantation, vascular anastomotic bone transplantation and Allogeneic osteochondral transplantation!
　　 Will this kind of surgery cause secondary damage?
　　 But...
　　 It is undeniable that if it can be completed perfectly, this is indeed a rare good method for the repair of avascular necrosis of the femoral head!
　　 After hearing what Chen Cang said, Lao Ma was stunned!
　　 Compared with Geng Hongming, Lao Ma thinks more.
　　 He has even made up the whole procedure in his mind.
　　 The more I think about it, the more I think it is feasible, and the more I think about it, the more I think the chances of success of the whole operation are actually very high!
　　 He suddenly looked up at Chen Cang, and couldn't help asking, "Cang'er! I really taught you?"
