Chapter 2013 [2013] Fine Workmanship
After hearing this, Dr. Hu also raised his concerns: "The blood vessel is only so big, if it is injected with blood, won't it burst?"
Small blood vessels are very easy to burst, which is also the reason why ophthalmologists are afraid to perform interventional surgery on her. The embolus lands in a small blood vessel, and it is easy to burst the blood vessel by forcibly injecting too much pressure. Don't talk about thrombolysis at that time, it will directly blind your eyes.
"So pay attention to the hemodynamic possibility provided by the peripheral collateral circulation to this part of the arterial network, as well as 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 must pass through the dural sheath and then enter the cranium. The ophthalmic artery is also the first branch of the internal carotid artery. It is on the lower and outer side of the optic nerve When going inward and crossing the optic nerve, the central retinal artery CRA emerges, which is where the doctor initially judged that Mr. Hu's disease is."
Mr. Liu leaned closer and saw that the brush in her hand was like a painter, no, like an engineering designer. A stroke of a stroke does not need to be modified at all, which can be regarded as the exquisite workmanship of engineering.
To say that Cao Yong can draw like this, Thaksin believes that he is a famous neurosurgery expert. This Dr. Xie, as far as he knew, was just a medical student. Mr. Liu couldn't take his eyes off it. The more he watched her paint, the less he felt that her painting was much different from Cao Yong's.
Cao Yong may be a well-known artist, so he sketched a few simple strokes for his family to set the framework. Xie Wanying's painting is like adding various details and coloring to a sketch.
It cannot be said which is better, the framework or the details behind it, in fact, there are technical requirements.
The detail of the latter painting can be clearly distinguished at the same time, which is very powerful.
"The retina actually has two vascular networks, one part supplies the inner part of the retina called the retinal artery network, and the one that supplies the outer part of the retina is the choroidal vascular network that supplies the outside of the retina. The central retinal artery is divided into three segments. The first is the inner orbital segment, starting from the starting point It extends to pass through the dural sheath around the optic nerve. The next intradural segment is between the optic nerve and the dural sheath. The inner segment of the nerve is inside the optic nerve. The place where the central retinal artery and retinal artery branches join is here, the optic nerve Nipples." Xie Wanying took out a red pen to draw circles when she reached the important point.
Mr. Liu was fascinated by it, and explained that as long as the anatomical diagrams are drawn well, they are no worse than the paintings of the Academy of Fine Arts, and they are still attractive.
"In some people, their retina is supplied by the ciliary retinal artery, which is a branch of the posterior ciliary artery. Therefore, Dr. Hu must thoroughly check these blood vessels for this reason, so as to understand where the problem is. The diameter of the optic nerve head and the central retinal artery is about 160 um. There are several stenosis of this artery, one is the place where it passes through the cribriform plate, and the other is the place where the proximal end passes through the dura mater and enters the optic nerve. These stenosis parts It's probably where the emboli we're looking for are located, because emboli are most likely to get lodged in these places."
"After finding the embolus, how do you get out what you said?" Mr. Liu followed what Xie Wanying said without hesitation.
Dr. Hu could tell that her husband understood and listened with great interest, so he couldn't help but be amused. Having said that, this classmate Xie really described the anatomy diagram very well. Now we only need to see how Xie explained the key issues and key solutions.
