After hearing this, Dr. Hu also raised his concern: "The blood vessels are only that big. If the blood flow is injected, will it explode?"

Small blood vessels are very easy to explode, which is also the reason why the ophthalmologist is not very brave to perform interventional surgery on her. The emboli falls into the small blood vessels and forcefully injects too much pressure to easily burst the blood vessels. Not to mention thrombolysis, then directly

Blinded your eyes.

"So we should pay attention to the possibility of the hemodynamics provided by the surrounding 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 the blood vessel direction diagram drawn by Senior Brother Cao to his family,"

The ocular artery is from here, this is the cavernous sinus of the internal carotid artery. After it comes out, it passes through the dural sheath and then enters the intracranial. The ocular artery is also the first branch of the internal carotid artery. It is located on the lower lateral side of the optic nerve.

When you move inward across the optic nerve, you will issue a CRA in the central retinal artery, which is where Teacher Hu is temporarily diagnosed by the doctor."

Mr. Liu approached and looked at the pen in her hand like a painter. No, it was like an engineering designer. If you clicked one stroke, you would not need to modify it at all. It can be regarded as the meticulous work of engineering.

He believed that Cao Yong could paint like this. He was a famous neurosurgeon expert. Dr. Xie, as far as he knew, was just a medical student. Mr. Liu was blinded. The more he looked at her, the less he felt that she had painted.

How much difference is with Cao Yong?

Cao Yong may be a famous master. He roughly drew a few brief strokes for his family and framed them. Xie Wanying's paintings were like adding various details and colors to the sketch draft.

It cannot be said that the frame or the details behind it are more awesome, but they actually require technical level requirements.

It is amazing that the latter is drawn in detail and can be distinguished clearly.

"The retina actually has two blood vessel networks. Some of them supply the inner part of the retina is called the retinal artery network. The outer part of the retina is the choroidal blood vessel network that supplies the outer part of the retina. The central retina artery is divided into three segments. The first is the intraorbital segment, from the starting point

Extends through the dural sheath around the optic nerve. The second intradural segment is between the optic nerve and the dural sheath. The inner nerve segment is within the optic nerve. The branch of the central retinal artery and the retinal artery are connected here.

**.” When he went to the key point, Xie Wanying took out a red stroke and drew circles.

Mr. Liu was fascinated by this, and it was explained that as long as the anatomical drawings were beautiful, they were not inferior to those of the paintings of the Academy of Arts, they were still attractive.

"There are some people whose retina is supplied by the ciliary body retinal artery, which is a branch of the posterior ciliary artery. So Dr. Hu must thoroughly examine these blood vessels to understand what is wrong.

The diameter of the optic nerve head, the central retinal artery is about 160

um, there are several stenosis in this artery, one is the place where it passes through the screen plate, and the other is the proximal end that passes through the dura mater and enters the optic nerve. These stenosis may be the location of the emboli we are looking for, because the stenosis

The child is most likely to be embedded in these places."

"After finding the sheath, how did you say flow out?" Mr. Liu followed Xie Wanying without hesitation.

Dr. Hu could hear that her husband understood and listened with relish, and couldn't help but be happy. Having said that, this student Xie did explain the anatomy diagram very well. Now it's all about how student Xie explains the key problems and the key solutions.
