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.
Is it no wonder that after searching many hospitals, I found Mr. Zhang from Guozhi here specifically to find Dr. Ren and Dr. Xie?
As Director Fang said before, Guozhi is the most famous hospital for heart treatment in the country, and patients will definitely be advised to come to Guozhi. There was no need to say that I had to find Mr. Zhang at the beginning.
Director Fang said: "I first went to Dr. Dou to ask about the situation. Before I went to Dr. Dou, I asked Professor Li from the National Association and the doctor from Pinghuai."
It can be said that I have searched all over the world for several famous cardiovascular experts in the most famous hospitals.
Ren Zhelun walked to Boss Zhang's desk.
There are patient records on the table.
Xie Wanying followed closely.
In the front, Ren Zhelun opened the medical record and listened to his boss Zhang Huayao whisper: "I have had a stent done before."
In-stent restenosis is very common, but the current stent materials are difficult to describe. In fact, it is very good that this patient can persist in re-stenosis for two to three years.
What is this patient's biggest problem now? Restenosis of the stent is one thing, but the biggest fear is that other blood vessels will become diseased again.
I opened the medical record and saw the results of the patient's reexamination in other hospitals. This time, the patient did not undergo coronary angiography again, but underwent CT angiography directly.
"Four lesions -" Ren Zhelun's voice became smaller and smaller, and the breath in it became more and more complex.
Now summarize the patient's current situation. The patient's medical history focused on chronic obstructive pulmonary disease. In the past, due to work travel, the patient had an emergency emergency, so the stent was done in a hospital other than the capital. This time I had angina pectoris again and went to the National Association for medical treatment. A reexamination found in-stent restenosis and four-vessel disease.
Four-vessel disease definitely refers to the four-vessel disease of the coronary arteries.
It is true that four-vessel lesions are relatively rarely heard. What laymen hear the most is single-vessel lesions and three-vessel lesions.
When doctors talk about three-vessel disease, they will say it is very serious in a very serious tone.
The four-vessel disease is undoubtedly the most serious.
How many coronary blood vessels are there?
Which branches are referred to as single-branch disease, three-branch disease, and four-branch disease?
The blood vessels of the human body are surrounded by large blood vessels and countless small blood vessel branches, forming a dense and countless network of blood vessels like a spider web.
A large number of small blood vessels branch off from large blood vessels, highlighting the importance of large blood vessels such as rivers in river systems. Medicine is no different from other disciplines. When necessary, we only focus on the key points when treating diseases. Therefore, when doctors talk about coronary artery disease, they only refer to the large coronary vessels.
There are four large blood vessels in the coronary arteries, and the four large blood vessels are not in a parallel relationship.
The naming of blood vessels in medicine is like naming individual road sections in the transportation system. The four large blood vessels of the coronary arteries are four large blood vessel segments.
As mentioned before, the coronary arteries originate from the aortic sinus inside the aortic root and are divided into left and right coronary arteries. The left coronary artery is divided from the left main trunk into the left anterior descending branch and the left circumflex branch. Both are thick. These three segments plus the right coronary artery are The branch lesions are four-branch lesions.
If the upper left main trunk is removed, it is a so-called three-vessel disease. It can be seen that the left main trunk is generally more difficult to cause accidents.
The most common cause of trouble is the left anterior descending artery, which is the most common single-vessel disease. Therefore, single-vessel left anterior descending artery disease is the most common case used by doctors to try various new surgeries, 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 disease cases mentioned above.
