Seeing that the family members can communicate, Cao Yong went to the deeper knowledge: "The most important feature of the retinal arterial network is that its blood vessels are very thin in diameter. At this stage, no catheter can enter this place. If there is an embolus in this place, it will be very difficult. Trouble. Physicians have limited coping strategies for this.”

   "Yes, but I seem to have heard people say that the blood vessel is blocked and the thrombectomy can be done." Mr. Liu asked around and told all the information he had heard for his wife, and did not want to give up any chance to treat his wife.

   Thrombolytic thrombectomy, Mr. Liu’s words should refer to ophthalmic artery interventional surgery. I mentioned before that the pathogenesis of this disease is similar to that of myocardial infarction, and similar interventional methods, such as drug thrombolysis and interventional surgery, can be used to deal with it. It\'s just that the ophthalmology department can\'t do such interventional surgery, why is that?

"Whether thrombolysis or catheter intervention for thrombectomy, all must be time-sensitive." Cao Yong did not completely deny the news that the family members inquired, but seeking truth from facts, the family members who are laymen must have heard the information is not professional enough, it is estimated that some The information may be wrong, "Generally speaking, the best results are obtained within a few hours after the onset of the disease. Your wife, Dr. Hu is a doctor himself, and she knows that this is an emergency. It is right to go to the ophthalmologist immediately and take first aid measures. Also because your wife\'s self-rescue behavior was very timely, the result of violent blindness did not occur, and now the embolus is left in a state that cannot be moved. I saw that the medical records written by the ophthalmology department are roughly like this. The previous treatment steps of the ophthalmology department were not given. She did an angiography, and she would not have considered interventional thrombectomy for the patient at that time."

   "Why didn\'t the ophthalmologist perform surgery on my wife?" Dr. Liu asked, suspecting that the ophthalmologist\'s treatment was negligent and not active enough.

  Ophthalmology bosses know that the patients they treat are colleagues, how dare they be negligent, and their colleagues cannot deceive them.

Cao Yong smiled at this point, not to defend his peers but to make it clear to his family: "The effect of thrombolytic therapy through the ophthalmic artery is far less than that of interventional surgery for myocardial infarction. The retinal artery is the terminal blood vessel, which is what I said just now. , the diameter of its blood vessels is too thin, and there is no such equipment that can break through the physical limit to enter this place. Doctors cannot send the catheter to a precise location for thrombolysis and stent placement like in cardiovascular interventional surgery. The effect of the operation is to make a question mark."

   Specifically, in cardiovascular interventional surgery, catheters and stents can be delivered to the coronary artery, the main artery supplying cardiomyocytes, for precise treatment like a shell hitting the diseased site. The central retinal artery is too thin to do this, and its interventional surgery cannot be regarded as a real interventional surgery.

   For this reason, it can be seen that there are not many such interventional operations performed by the ophthalmology department. But it cannot be said that there is no such thing, it depends on whether the patient\'s condition meets the indications for surgery. Doctors choose to perform ophthalmic artery interventional surgery for some patients, mainly because of the possibility that the embolus is not in the retinal artery but in the internal carotid artery or proximal ophthalmic artery.
