"You are right." As the squad leader, Yue Wentong announced on the spot that the patient's basic situation was correct, and he said the patient's self-reported medical history. "The patient had an interventional operation in the Department of Cardiovascular Medicine of Zhongshan First Affiliated Hospital. A few months ago, the condition seemed not serious. He had not passed the emergency room, but his chest was not comfortable to go to the outpatient clinic for medical treatment. After an angiography examination, he found that the anterior descending branch of the left coronary artery was stenosis. The degree of stenosis was relatively serious according to what the patient said at that time, so a stent was placed after the balloon was expanded."

It's her hometown. Xie Wanying thought.

"As for why it's more narrow?" Yue Wentong glanced at Feng again as he said this.

Does this question need to be asked?

It is too common to intrastent restenosis. Moreover, he just said that the patient was sent to the emergency department because of intrastent restenosis?

Feng Yicong blinked at the ceiling, hating himself for speaking in a daze. The class monitor is the top student in the class, second only to the female top student Yingying.

How could he suspect that the patient had restenosis in the stent before the coronary angiography was before the patient had a coronary angiography. Perhaps it was blocked by other arteries, or perhaps it was some other reason.

Pan Shihua swallowed the mouth and said justice to Classmate Feng, saying: "I will be sent to the emergency room in a few months, and I just had an angiography a few months ago and there is no problem for other blood vessels. The possibility of another accident in the stent should be relatively high. - Yingying, what do you think?"

When asked by his classmates about his opinion, Xie Wanying recalled that the drug stent had not yet been released in this era, and naked stents were too prone to restenosis, which became a major obstacle to stent surgery. In fact, the direction of the two students' questions was correct. However, the class monitor was a very cautious person and would not say anything randomly before the results of the angiography were released. There was nothing in the class that did not say. It might be that patients who came to the emergency room for restenosis were very common, which means that this reason was unlikely to be that this patient needed Senior Brother Jin to come down specifically in a special place.

"The squad leader didn't finish his words." Xie Wanying said.

After she pointed out that she had not finished speaking, Yue Wentong was stunned for a moment, and his eyes were meaningful to her. The two students in the class seemed to be a little bit amazing. The difference is that the logic of the speculation by Student Pan was at a shallow level, and the logic of the speculation by the female academic master in their class was at a deep level, and there were brain secrets that others didn't know.

"The teachers decided to do a radial artery puncture on him." Yue Wentong said the key point.

"If you don't pass through the femoral artery, you have to pass through the radial artery, why?" Feng Yicong asked.

The surgical approaches for PCI are generally these three: femoral artery, radial artery, and brachial artery.

Among the three arteries, although the femoral artery is the farthest from the heart, it is the thickest and is easiest to puncture and put into the guidewire. The radial artery and brachial artery are closer to the heart, but the blood vessel diameter is small, and there are several thresholds to pass in the path to the coronary artery of the heart. The road is not as smooth as the femoral artery, so it is not easy to succeed.

Clinicians basically choose the surgical path of femoral artery without special circumstances. Choosing the radial artery must be a contraindication that triggers the femoral artery approach in special circumstances.

"The patient has arteriosclerotic occlusion? Are you taking anticoagulants?" Pan Shihua pointed out the possible reasons.
