BXBX NOVEL Chapter 2013: 【2013】Seiko
Small blood vessels are very easy to burst, which is also the reason why ophthalmologists are reluctant to perform interventional surgery on her. The emboli land in the small blood vessels, and it is easy to burst the blood vessels by forcibly injecting too much pressure. Don\'t talk about thrombolysis, just blind your eyes.
"So we should pay attention to the possibility of the hemodynamics provided by the peripheral collateral circulation to this part of the arterial network, and the anatomical position of the blood vessel direction." Xie Wanying said, and then processed the blood vessel direction map that Brother Cao drew for the family, " The ophthalmic artery comes from here. This is the cavernous sinus of the internal carotid artery. After it comes out from here, it will pass through the dural sheath and then enter the brain. The ophthalmic artery is also the first branch of the internal carotid artery. It is below the optic nerve. When it goes inward and crosses the optic nerve, the central retinal artery CRA is issued, which is the location where the doctor temporarily judged Mr. Hu\'s disease."
Mr. Liu approached and looked at the pen in her hand, like a painter, no, like an engineering designer, there is absolutely no need to revise a single stroke, which can be praised as the meticulous work of engineering.
Said that Cao Yong can paint like this, Thaksin, he is a famous neurosurgery expert. This Doctor Xie, as far as he knows, is just a medical student. Mr. Liu kept his eyes fixed. The more he watched her painting, the less he felt that her painting was much different from that of Cao Yong.
Cao Yong may be a famous artist, so he just sketched a few sketches for his family members and framed them. Xie Wanying\'s painting is like adding various details and coloring to the sketch.
It cannot be said that the frame or the details behind it is more powerful, in fact, there must be technical level requirements.
The latter painting is very fine and can be clearly distinguished, which is very powerful.
"The retina actually has two vascular networks. One part supplies the inner retina called the retinal arterial network, and the outer retinal network is supplied by the choroidal vascular network, which supplies the outer retina. The central retinal artery is divided into three segments. The first is the intraorbital segment, starting from the It extends through the dural sheath around the optic nerve. The second intradural segment is between the optic nerve and the dural sheath. The intraneural segment is inside the optic nerve. The central retinal artery and the branch of the retinal artery join here. The optic nerve **." Xie Wanying took out the red pen to draw a circle when she reached the key point.
Mr. Liu was fascinated by it, explaining that as long as the anatomical drawings are good-looking, they are no worse than the paintings of the Academy of Fine Arts, and they are still attractive.
"In some people, their retinas are supplied by the ciliary retinal artery, which is a branch of the posterior ciliary artery. So let Dr. Hu thoroughly examine these blood vessels for this reason, so as to understand what is wrong. In the head of the optic nerve, the diameter of the central retinal artery is about 160um. There are several stenoses in this artery, one is where it passes through the cribriform plate, and the other is where the proximal end passes through the dura and enters the optic nerve. These stenoses may That\'s where the emboli we\'re looking for are the places where emboli are most likely to become incarcerated."
"After finding the embolus, how did you say it came out?" Mr. Liu had followed Xie Wanying\'s words without hesitation.
Dr. Hu could hear that her husband understood and listened with relish, and couldn\'t help but be overjoyed. Having said that, this student Xie really did a good job of explaining the anatomy diagram. Now I just look at how Xie explained the key issues and the key solutions.
Thank you for your support! ! Good night dears~
