BXBX NOVEL Chapter 2101: 【2101】Won the hemp
First of all, in human embryos, all the cerebral blood vessels originate from the internal carotid artery. The internal carotid artery sends out two vascular trunks other than the ophthalmic artery, one of which is the anterior choroidal artery.
It is interesting that such an artery that seems to be very important has chosen to degenerate when human beings continue to grow. For this reason, some of its starting points have become from the middle cerebral artery and the posterior communicating artery, and most people still Start from the lateral wall of the internal carotid artery.
A degenerate artery is definitely not characterized by being thick like the trunk of the aorta grows into a tree trunk, but with a long and thin stroke, which is more prone to occlusion. Wouldn\'t it be completely unimportant to say this degenerated artery? Otherwise why degenerate?
According to human research, the degenerated parts of the human body have their own special significance, and no part of the human body can be said to be completely useless. The same is true for the anterior choroidal artery. It supplies blood to the basal ganglia, the optic tract, the hippocampus, and other important brain tissue areas.
If it is ischemia, without the support of the retrochoroidal artery with the anastomotic branch, the patient will have symptoms such as hemiplegia and blindness.
The consequences of ischemia are terrible, and bleeding is definitely more terrible.
Is the anterior choroidal artery long aneurysm? Long, the number can account for a few percent of the incidence of aneurysm cases, can not be said to be rare.
During the first cerebral vascular examination, the doctor had a photo of the anterior choroidal artery. However, it is not an arterial trunk, it is very small, and the blood vessels displayed on the DSA image are light, dark, unclear and not eye-catching.
The doctor took a glance and saw that there was no ischemic part showing no swelling. There should be no major problem.
But the microcatheter in the hand of the main surgeon who is now replaced can smoothly and quickly enter the prechoroidal artery, indicating that the diameter of this artery has become larger?
The anterior choroidal artery should have a small diameter according to common sense. Its larger diameter may indicate a problem, it is going to become an aneurysm.
Aneurysms in the anterior choroidal artery tend to be small in size. Even so, as long as the aneurysm in this place becomes slightly larger, the aneurysm with a larger volume like a reservoir can easily control the fluctuation of the anterior choroidal artery with a small diameter and a small water flow below.
The two-dimensional image map is indeed easy to deceive people in the early stage of the disease. The cerebrovascular map has the characteristics of rich bifurcations. If the blood vessels are carefully explored, it can be said to be densely packed, comprehensively interlaced, like a mess.
If doctors rely on the existing knowledge base of medicine to make calculations, it is much faster and more accurate than relying on hand feel. The hand-feel reflex is pure and natural, and it requires no brains and no calculation.
All those who are watching the surgery can only think in their hearts: Cao Yong has won again.
The microcatheter is advanced to a certain point, and a coil is placed to complete the embolization. After checking the ophthalmic artery, the opportunity appeared...
After half an hour, the operation was over.
The nurse uses the lathe to take the patient back to the ward.
"Director Zhai." Deputy Director Lu said, accompanying Zhai Yunsheng, a great expert, to prepare to take the first step.
At this moment, Zhai Yunsheng looked at the little girl standing there.
Xie Wanying was facing the lead glass and seemed to be thinking about the surgery scene just now to sort it out.
Her brain can\'t keep up with Senior Brother Cao\'s feel, but she can review the operation experience, which is a very good learning opportunity.
