As soon as the topic about the case started, all the doctors on the scene heard: this patient's condition was not simple.
No wonder I went to so many hospitals before finally finding Guozhi Zhang to look for Doctor Ren and Doctor Xie?
As Director Fang said before, Guozhi is the most famous hospital in the country for treating heart diseases, and he would definitely recommend patients to come to Guozhi. There was no need to say that they had to come to Zhang Da Lao at the beginning.
Director Fang said, "I went to see Doctor Du first to ask about the situation. Before I went to see Doctor Du, I went to ask Professor Li from the National Association and the doctor at Pinghuai."
I have searched all the famous cardiovascular experts in the most famous hospitals.
Ren Zhelun walked to Boss Zhang’s desk.
The patient's medical records are on the table.
Xie Wanying followed closely.
In front, Ren Zhelun opened the medical record and heard his boss Zhang Huayao whisper, "He had a stent done before."
...
...
In-stent restenosis is very common, because the current stent materials are hard to describe. In fact, it is very good that this patient can survive for two or three years without restenosis.
What is the biggest problem for this patient now? Stent stenosis is one thing, but the most worrying thing is that other blood vessels will become diseased again.
I opened the medical record and saw the results of the patient's reexamination at another hospital. This time, the patient did not undergo coronary angiography again, but directly underwent CT angiography.
"Four lesions--" Ren Zhe Lun's voice became smaller and smaller, and the breath in it became more and more complicated.
Now let me summarize the patient's current condition. The main medical history of the patient is chronic obstructive pulmonary disease. Previously, due to work trips, he had an emergency emergency and had a stent placed in a hospital other than the capital. This time, he had angina pectoris again and went to the National Association for medical treatment. A follow-up examination revealed restenosis in the stent and four-vessel disease.
Four-vessel disease definitely refers to the disease of the four vessels of the coronary arteries.
Four-vessel lesions are indeed rarely heard of. The most common ones heard by laymen are probably single-vessel lesions and three-vessel lesions.
When doctors talk about triple-vessel lesions, they will use a very serious tone and say that they are very serious.
Four-branch lesions are undoubtedly the most serious.
How many coronary arteries are there?
Which branches are referred to as single-branch lesions, three-branch lesions, and four-branch lesions?
The blood vessels in the human body are composed of large blood vessels and countless small blood vessels branches, forming a spider web-like vascular network that is densely packed and countless.
A large number of small blood vessels branch out from the large blood vessels, highlighting the importance of large blood vessels, like the great rivers in the river system. Medicine is no different from other disciplines. When treating a disease, only the key points are focused. Therefore, when doctors talk about the lesions of several coronary arteries, they are only referring to the large coronary blood vessels.
There are four major coronary blood vessels, and the four major blood vessels are not parallel to each other.
The naming of blood vessels in medicine is like the naming of road sections in the traffic system. The four major coronary vessels are four major blood vessel segments.
It has been mentioned before that the coronary artery starts from the aortic sinus inside the aortic root and is divided into left and right coronary arteries. The left coronary artery is divided into the left anterior descending branch and the left circumflex branch from the left main trunk. Both are thick. If these three segments plus the right coronary artery are diseased, there will be four branches that are diseased.
If the left main trunk is removed, it is the so-called three-branch disease. It can be seen that the left main trunk is generally less likely to have problems.
The most vulnerable part 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, and the internal mammary artery is usually replaced.
The TECAB surgery that Company B claims to be able to perform refers only to the single-vessel lesion case mentioned above.
