Yes, the catheter for interventional surgery can only be placed at the proximal end of the ophthalmic artery to inject medicine or place a stent. If these places are blocked, needless to say, there is a chance to place catheters and stents here, and the effect of thrombus removal and thrombolysis is relatively good.
good.
Catheters and stents are limited by the diameter of blood vessels and cannot deliver to the terminal blood supply vessels of the retina. The only remaining question is whether the thrombolytic drug can accurately reach the blocked position of the retinal artery through the ophthalmic artery and dissolve it. Maybe it can. But if the thrombolytic drug is feasible,
Why do you need to undergo this interventional surgery? It is like directly inserting veins all over the body.
Dr. Hu's ophthalmology doctor, as a big shot in the industry, knows the basics of these surgeries and will not deceive colleagues like Dr. Hu. After preliminary examination, it is judged that the possibility of emboli like Dr. Hu's is at the end is very high, and a thrombectomy stent is made.
I'm afraid it won't work.
There are risks with any surgery.
People have done research abroad before, and there is no difference in the therapeutic effect between intravenous thrombolysis and interventional local thrombolysis. This is the first. The second is that the risk of this interventional operation in ophthalmology is very high, which is higher than that of intravenous thrombolysis.
The incidence of adverse events with embolization is several dozen percent higher.
This interventional surgery in ophthalmology is not performed by an ophthalmologist. The ophthalmologist assists on site and must be performed by an interventional physician. From the above-mentioned incidence of surgical adverse events, it can be seen that this surgery requires a very high technical level of interventional surgeons.
.
Think about it, domestic interventional surgeries are still catching up with foreign countries, and the training of interventional surgeons can be said to have not reached foreign standards. There are very few people who truly have this level of ophthalmic interventional technology. Even foreign experts can do this, and you are in China
There are very few expert doctors who can be found with such guarantees. What’s more, Dr. Hu’s condition is extremely rare, and the risk of interventional surgery is higher.
Finally, the results of Dr. Hu’s previous intravenous thrombolysis treatment confirmed that it was correct not to perform interventional surgery. This is because the emboli in Dr. Hu’s central retinal artery cannot be completely dissolved by thrombolytic drugs. In other words, if you perform interventional surgery locally
Thrombolysis is risky and equally useless.
After hearing what the doctor said, Mr. Liu lowered his head, indicating that the information he had obtained for his wife was invalid.
I am not an expert, so the fragmented information I hear from hearsay is definitely biased, which is normal.
Maybe his wife, Dr. Hu, almost gave up because she knew this was the case.
Mr. Liu looked worried and asked the doctor sincerely: "Last night, many doctors suggested that I come to see you, Dr. Cao. Is there nothing you can do about my wife's illness? In fact, what their doctors said last night
, I don’t quite understand what I heard. Is there any way to treat eye diseases other than neurosurgery?”
"I just told you about the eye treatment. Your wife was given thrombolytic drugs within a few hours, which removed part of the emboli and bought herself precious time so that the doctor could think of more ways to treat you.
My wife’s disease. From a preliminary look, the remaining part of your wife’s embolus should be calcified or cholesterol, so it cannot be dissolved. If it cannot be dissolved, the only option is to find a way to get out the embolus.” Cao Yong
Said, "Diseases like your wife's often occur together with strokes, which has shown that the two are closely related. Dr. Hu's disease is indeed an ophthalmic disease. From an anatomical point of view, the arterial system that supplies blood can be said to belong to
In the extraneural realm, the ophthalmic artery itself is a blood vessel entering the skull."
