"It's doing IVUS." Shin Youhuan smashed her fist down her palm, and finally remembered that there was such a specialty examination, saying, "I thought she was going to have an esophageal ultrasound, but I thought I'm not doing this thing, could I do it again during the operation

Do?"

IVUS is an intravascular ultrasound, which can also be used to check the intravascular condition of the coronary artery. The difference from coronary angiography is that it does not require fluoroscopy to develop the thickness of the blood vessels, but directly sends a micro ultrasound probe into the blood vessels.

To detect the internal conditions of the blood vessels, further examination will include future OCT, using infrared rays to measure blood vessels, which is more accurate than IVUS.

Why are the latter two technologies not commonly used clinically? The main reason is that they are expensive.

Relatively cheap coronary angiography can already achieve good efficacy, so why do you need to use these two technologies? Besides, after detecting these two technologies, the stent still requires the use of contrast technology. This is equivalent to the cost increasing exponentially, and the efficacy is

But there is not much difference. Doctors know which one to choose for ordinary people.

These two technologies are not clinically used. As long as any technological invention can survive, it will inevitably have its irreplaceable availability.

Like OCT, IVUS is much more accurate than coronary angiography.

This high accuracy can be used in many difficult cases.

For example, a patient has typical clinical symptoms. If a coronary angiography is performed, it is found that the stenosis of the stent is not required to place the stent at the limit. Legally, if a doctor puts a stent on the patient, it is an over-medical treatment and causes other sequelae, the patient will not relieve the symptoms.

At the same time, it brings other high risks. Doctors can only seek other evidence. At this time, IVUS may play a key role. IVUS, which cannot be seen with coronary angiography, can.

The reason is that the result of coronary angiography is only the size of the coronary lumen, and the inability to detect the blood vessel walls leads to underestimating the severity of blood vessel stenosis.

Gu Most patients with coronary heart disease have atherosclerotic plaques formed by atherosclerotic plaques. Only IVUS can detect early vascular wall sclerosis plaques and tell the doctor the severity of the lesions in this area. One step ahead of coronary angiography indicates that a stent needs to be placed.

.

The same goes for some young patients. Synthesis of coronary heart disease symptoms indicates severe stenosis. Doctors know that they may not have the age basis for atherosclerosis. If the patient does not place a stent at this time, it may also be accused if the patient is not given a stent.

Using IVUS to measure the condition of blood vessel walls can help doctors find more accurate evidence to judge. If the lesion of blood vessel walls is not serious, first pass through the thrombus, and then decide whether to place the stent after a certain period of time. It is not too late to treat it too much.

Overtreatment.

When it comes to Xiao Shugang, the patient, using coronary angiography may not necessarily show the stenosis or the stent may not necessarily be placed. What is more important is to check the condition of the blood vessel wall to see if there is any damage after a car accident.

"I can only look at this question from the inside but not from the outside." Shin Youhuan conducted academic exchanges through spokesperson Pan and Xie.

"Yingying said that the internal and external communication can be determined in which area the area to perform surgery is," said Pan Shihua.

"She means to solve the problem of the patient's surgical area restriction first, right?" Shin Youhuan asked.
