    After hearing this, Dr. Hu also raised his concerns: "The blood vessels are only so big, wouldn't they explode if blood is injected into them?"

    Small blood vessels are very easy to burst, which is why the ophthalmologist did not dare to perform interventional surgery on her.  The emboli lodge in small blood vessels, and excessive pressure can easily burst the blood vessels.  Don't talk about thrombolysis at that time, it will directly blind your eyes.

    "So we need to pay attention to the hemodynamic possibilities provided by the peripheral collateral circulation to this part of the arterial network, as well as the anatomical position of the blood vessels." Xie Wanying said, processing the blood vessel direction map that Senior 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 passes through the dural sheath and then enters the skull. 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 it goes inward and crosses the optic nerve, it emits the central retinal artery cra, which is where the doctor tentatively determined that Mr. Hu's disease developed."

    Mr. Liu came closer and looked at the pen in her hand like that of a painter, no, like an engineering designer. There was no need to modify the strokes after one stroke, which can be regarded as the precision work of engineering.

    ¡°It is said that Cao Yong can draw like this, Thaksin believes that he is a famous neurosurgery expert.  .  As far as he knew, this Doctor Xie was just a medical student.  Mr. Liu couldn't take his eyes away. The more he watched her painting, the less he felt that her painting was much different from Cao Yong's.

    Cao Yong may be a famous artist, but I just sketched a few sketches of his family members to form a framework.  Xie Wanying's painting is like adding various details and coloring to the original sketch.

    We can¡¯t say which one is better, the framework or the details behind it. In fact, both have technical requirements.

    The latter is very detailed and can be clearly distinguished at the same time, which is amazing.

    "The retina actually has two blood vessel networks. One part supplies the inner part of the retina called the retinal artery network, and the part that supplies the outer retinal network is the choroidal vascular network that supplies the outer part of the retina. The central retinal artery is divided into three segments. The first is the intraorbital segment, starting 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 intraneural segment is within the optic nerve. The central retinal artery and the branches of the retinal artery connect here, and the optic nerve  **." After drawing to the key point, Xie Wanying took out the red pen and drew circles.

    Mr. Liu was fascinated by it and explained that as long as the anatomical drawings are beautiful, they are no worse than those drawn by the Academy of Fine Arts, and they are still attractive.

    "In some people, their retinas are supplied by the cycloretinal artery, which is a branch of the posterior ciliary artery. Therefore, Dr. Hu needs to thoroughly examine these blood vessels to understand the cause of the problem. In  At the head of the optic nerve, the diameter of the central retinal artery is about 160 um. 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 mater and enters the optic nerve. These narrow places  That's probably where the emboli we're looking for are because emboli are most likely to become lodged in those places."

    "After you find the embolus, how do you say it will flow out?" Mr. Liu followed Xie Wanying's words without hesitation.

    Dr. Hu could tell that her husband understood and listened with gusto, and couldn't help but feel happy.  Having said that, this classmate Xie really explained the anatomy diagram very well.  Now let¡¯s just see how Mr. Xie explains the key issues and the key solution strategies.  (Remember the website address: www.hlnovel.com
