The topic of the case was just the beginning, and all the doctors on the scene heard it: this patient's condition 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 himself 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 is no need to insist on finding 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 went to ask 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.
Ren Zhelun opened the medical record earlier and listened to his boss Zhang Huayao whisper: "I have had a stent done before."
In-stent restenosis is very common, and it is difficult to describe the current stent materials. In fact, it is very good that this patient can persist in restenosis for two to three years.
What is the biggest problem for this patient now? Stent restenosis 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 re-examination in other hospitals. This time, the patient did not undergo coronary angiography again, but directly underwent CT angiography.
"Four lesions -" Ren Zhelun's voice became smaller and smaller, and the breath contained in it became more and more complex.
Now let’s summarize the patient’s current situation. The patient’s medical history focuses on chronic obstructive pulmonary disease. In the past, due to work travel, he had a sudden illness emergency, so he received a stent in a hospital other than the capital. This time he had angina pectoris again and went to the National Association for medical treatment.
, a review revealed 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 laypeople 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-branch 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, which highlights the importance of large blood vessels such as rivers in the river system. Medicine is no different from other disciplines. When treating diseases, only focus on the key points when necessary. Therefore, when the doctor talks about several coronary artery disease,
It only refers to the large blood vessels of the coronary arteries.
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 segments in the transportation system. The four large blood vessels of the coronary artery 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 arteries are 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 problems.
The most common cause of trouble is the left anterior descending artery, which is the most common single-vessel disease. Therefore, single-vessel disease of the left anterior descending artery is the most common case used by doctors to try out various new surgeries. The internal mammary artery is usually used to replace it.
.
The TECAB surgery that Company B claims to be able to perform only refers to the single-vessel disease cases mentioned above.
