Yes, the catheter of the 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 a catheter and a stent here, and the effect of thrombectomy and thrombolysis is better.
The catheter and stent are limited by the diameter of the blood vessels and cannot reach the terminal blood supply vessels of the retina. The only remaining thrombolytic drugs can reach the blocked position of the retinal artery through the ophthalmic artery and dissolve it. Maybe it can. But if the thrombolytic drugs are feasible, why do we need to do this interventional surgery? It's the same as directly injecting systemic veins.
Dr. Hu's ophthalmologist is a big shot in the industry and knows the basis of these surgeries. He will not deceive colleagues like Dr. Hu. After preliminary examination, it was determined that the possibility of embolus in Dr. Hu's case was very high at the end, and the embolus removal stent was unlikely to work.
Any surgery has risks.
Foreign countries have already conducted research and found that there is no difference in the therapeutic effects of intravenous thrombolysis and interventional local thrombolysis. This is the first point. The second point is that the risk of interventional surgery in ophthalmology is very high, and the adverse incidence rate is several tens of percent higher than that of intravenous thrombolysis.
This interventional surgery in ophthalmology is not performed by ophthalmologists, but by ophthalmologists who assist on site, and must be performed by internal medicine interventional doctors. From the above-mentioned incidence of adverse events, it can be seen that this surgery requires a very high level of technical skills from the interventional surgeon.
Think about it, domestic interventional surgery is still catching up with foreign countries, and the training of interventional surgery doctors can be said to be below foreign standards. There are very few people with this level of ophthalmic interventional technology. Foreign experts can do this, and you can find very few such reliable experts in China. What's more, Dr. Hu's is an extremely rare case of bilateral seizures instead of unilateral seizures, so the risk of interventional surgery is even higher.
Finally, Dr. Hu's previous intravenous thrombolysis treatment results confirmed that it was correct not to perform interventional surgery. Because the embolus in Dr. Hu's central retinal artery cannot be completely dissolved by thrombolytic drugs. In other words, if you perform interventional surgery for local thrombolysis, the risk is high and it is also useless.
After hearing what the doctor said, Mr. Liu lowered his head, indicating that the information he had obtained for his wife was invalid.
...
...
Since you are not an insider, the fragmented information you hear from others is bound to be biased, which is normal.
Perhaps it was because his wife, Dr. Hu, had known this earlier that she almost gave up.
Mr. Liu looked worried and asked the doctor earnestly, "Many doctors suggested that I come to you last night, Dr. Cao. Do you still have no solution for my wife's illness? In fact, I didn't quite understand what the doctors said last night. Is there any solution for eye diseases by going to a neurosurgeon?"
"I just told you about the ophthalmic treatment. Your wife was given thrombolytic drugs within a few hours, which removed part of the embolus and bought precious time for the doctor to think of other ways to treat your wife's disease. Now it seems that the remaining embolus of your wife is probably calcified or cholesterol, so it cannot be dissolved. If it cannot be dissolved, we can only find a way to get it out." Cao Yong said, "Your wife's disease often occurs together with cerebral stroke, which shows that the two are closely related. Doctor Hu's disease is an ophthalmic disease. From the anatomical relationship, the blood supply artery system can be said to belong to the category of extraneural. The ophthalmic artery itself is a blood vessel entering the skull."
