Chapter 3748 【3748】The Most Serious

The topic of the case was just the beginning, and all the doctors on the scene heard it: this patient's situation is not simple.

No wonder you searched many hospitals and then found Mr. Zhang Guozhi to come here to find Dr. Ren and Dr. Xie?

As Director Fang himself said before, Guozhi is the most famous hospital for heart treatment in the country, and he will definitely recommend patients to come to Guozhi. At the beginning, there was no need to say that he had to find Mr. Zhang to come here.

Director Fang said: "I went to Doctor Du first to ask about the situation. Before I went to Doctor Du, I went to ask Professor Li from the National Association and the doctor from Pinghuai."

It can be regarded as looking for several famous cardiovascular experts in the most famous hospitals.

Ren Zhelun walked to Mr. Zhang's desk.

There are patient records on the table.

Xie Wanying followed closely.

Ren Zhelun opened the medical records before, and heard his boss Zhang Huayao whisper: "I have done stents before."

In-stent restenosis is very common, and it is hard to describe the current stent materials. In fact, it is very good for this patient to persist in restenosis for two or three years.

What is the biggest problem with this patient right now? Stent restenosis is one thing, but the most fear is that other blood vessels will become diseased again.

Open the medical record and see the results of the patient's reexamination in other hospitals. This time, the patient did not undergo coronary angiography again, but directly underwent CT angiography.

"Four branch lesions—" Ren Zhelun's voice became smaller and smaller, and the breath in it became more and more complicated.

Now summarize the patient's existing situation. The patient's medical history focused on chronic obstructive pulmonary disease. In the past, due to business trips, the stent was performed in a non-capital hospital in other places for emergency treatment of sudden illness. This time I suffered from angina pectoris again and went to the National Association for medical treatment. After a re-examination, I found in-stent restenosis and four-vessel disease.

Four-vessel disease refers to the four-vessel disease of the coronary artery.

Four-vessel disease is indeed relatively seldom heard, and laymen should hear most about single-vessel disease and three-vessel disease.

When the doctor talks about the three-vessel disease, he will say it is very serious in a very serious tone.

Four branch lesions are undoubtedly the most serious.

How many coronary arteries are there?

Which ones are referred to for single-vessel lesions, three-vessel lesions and four-vessel lesions?

The blood vessels of the human body are surrounded by large blood vessels plus countless small blood vessel branches, like a spider web-like blood vessel network, densely packed and countless.

A large number of small blood vessels are separated from large blood vessels, which highlights the importance of large blood vessels such as large rivers and rivers in the river system. There is no difference between medicine and other disciplines, and when it is necessary to treat and see a doctor, we only focus on the key points. Therefore, when doctors talk about several lesions of coronary vessels, they only refer to the large coronary vessels.

There are four major blood vessels in the coronary artery, and the four major blood vessels are not in a parallel relationship.

The naming of blood vessels in medicine is like the separate naming of road sections in the transportation system. The four great vessels of the coronary arteries are the four great vessel segments.

It has been said before that the coronary artery starts from the aortic sinus in the root of the aorta and is divided into left and right coronary arteries. The left coronary artery is divided into left anterior descending branch and left circumflex branch from the left main artery, both of which are thick. Four-branch disease occurs when the branch is affected.

If the upper left trunk is removed, it is the so-called three-vessel disease. It can be seen that the left trunk is generally more difficult to have accidents.

The most prone to accidents is the left anterior descending artery, which is the most common single-vessel lesion. Therefore, single-vessel lesions of the left anterior descending artery are the most commonly used cases for doctors to try various new operations, and the internal mammary artery is usually replaced.

The TECAB surgery that Company B claims to be able to perform only refers to the single-vessel lesion cases mentioned above.
