"I have heard people talk about this. After I got home, I roughly looked through the medical textbooks my wife kept at home." Mr. Liu is also a high-level intellectual and can understand part of what the doctor says.
Seeing that the family members were able to communicate, Cao Yong went to more in-depth knowledge: "The most important feature of the retinal artery network is that its blood vessel diameter is very thin. At present, no catheter can enter this place. If there is an emboli in this place, it will be very serious."
trouble. Doctors have limited strategies to deal with it.”
"Yes, but I seem to have heard someone say that clogged blood vessels can be treated with thrombolysis and thrombectomy." Mr. Liu asked around and told all the information he had learned for his wife, not wanting to give up any chance to treat his wife.
Thrombectomy and thrombolysis, Mr. Liu should refer to ophthalmic artery interventional surgery. As mentioned before, the pathogenesis of this disease is similar to that of myocardial infarction, and it can be treated with similar interventional methods, such as drug thrombolysis and interventional surgery.
It’s just been said that ophthalmology cannot perform such interventional surgery. Why is that?
"Whether it is thrombolysis or catheter-based interventional thrombectomy, timeliness is the key to everything." Cao Yong did not completely deny the information the family members heard from him, but he was realistic. The family members were laymen and the information they heard was certainly not professional enough.
The information will be wrong, "Generally speaking, treatment is best within a few hours after the onset of the disease. Your wife, Dr. Hu is a doctor himself. He knows that this is an emergency. It is right to see an ophthalmologist immediately and take first aid measures."
Also because your wife's self-rescue behavior was very timely, the result that would have caused blindness did not occur. Now the embolus is partially left and cannot be moved. I read the medical records written by the ophthalmology department, which is roughly the situation. The ophthalmology department did not provide any previous treatment steps.
When she performed angiography, she would not consider performing interventional thrombectomy and thrombolysis surgery on the patient at that time."
"Why didn't the ophthalmology department perform surgery on my wife?" Dr. Liu asked, wondering if the ophthalmologist's treatment was negligent and not aggressive enough.
The big ophthalmologists know that the patients they are treating are fellow patients, so how can they dare to be careless? They cannot be deceived by their peers.
Cao Yong smiled at this point, not to defend his colleagues but to make it clear to his family members: "The effect of thrombolytic treatment through the ophthalmic artery is far less effective than the interventional surgery for myocardial infarction. The retinal artery is the terminal blood vessel, which is what I just said.
, the diameter of its blood vessels is too thin, and there is no such equipment that can break through the physical limit and enter this place. Doctors cannot send the catheter to a precise location to remove thrombolysis and place a stent like in cardiovascular interventional surgery. The effect of the surgery is to make a
Question mark."
Specifically, cardiovascular interventional surgery can send catheters and stents to the main arteries that supply myocardial cells, the coronary artery, and treat it as precisely as a cannonball hits the diseased area. The surgical effect of thrombus removal and thrombolysis can naturally be immediate. Central retinal artery blood vessel
If it is too thin to do this, its interventional surgery cannot be considered an interventional surgery in the true sense.
For this reason, it can be seen that there are not many such interventional surgeries in the ophthalmology department. But it cannot be said that there are none at all. It depends on whether the patient's condition meets the indications for surgery. Doctors choose to perform ophthalmic artery interventional surgeries on some patients, mainly because
Based on the consideration that the emboli may not be in the retinal artery but in the internal carotid artery or the proximal ophthalmic artery.
