Chapter 2101 【2101】Win Numb
The anterior choroidal artery is a rather miraculous artery in neurosurgery.
First of all, in the human embryo, all blood vessels in the brain initially come from the internal carotid artery, which gives off two vascular trunks other than the ophthalmic artery, one of which is the anterior choroidal artery.
Interestingly, such an artery, which seems to be very important, chooses to degenerate after humans continue to grow. For this reason, some people start from the middle cerebral artery and posterior communicating artery, and most people still From the lateral wall of the internal carotid artery.
A degenerated artery is definitely not as thick as the aortic trunk grows into a tree trunk, but rather has a long and thin stroke, which is more prone to occlusion. Is this degenerative artery completely unimportant? Otherwise, why degenerate?
According to human research, the degenerated parts of the human body have special meanings for their existence, 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, supplies blood to the optic tract, and supplies blood to the inner capsule of the hippocampus and other important brain tissue areas.
If it is ischemic and there is no support from the anastomotic branch of the posterior choroidal artery, the patient will experience symptoms such as hemiplegia and blindness.
The consequences of ischemia are terrible, and bleeding is definitely more terrible.
An aneurysm of the anterior choroidal artery? Long, the number can account for a few percent of the number of aneurysm cases, it cannot be said to be rare.
During the first full cerebrovascular examination, the doctor took photos of the anterior choroidal artery. However, it is not an arterial trunk, it is very small, and the blood vessels shown in the DSA image are light, dark, unclear and not eye-catching.
The doctor glanced at it and saw that there was no ischemic part showing no swelling, so there should be no major problem.
But now the microcatheter in the surgeon's hand can enter the anterior choroidal artery smoothly and quickly, indicating that the diameter of this artery has become larger?
According to common sense, the anterior choroidal artery should be small in diameter. Its larger diameter may indicate a problem, it is going to become an aneurysm.
Aneurysms of the anterior choroidal artery are often small in size. Even so, as long as the aneurysm in this place becomes slightly larger, larger than the aneurysm of the reservoir, it can easily control the fluctuation of the anterior choroidal artery with a small diameter and a small water flow.
Two-dimensional images are also very easy to deceive people in the early stage of the lesion. The cerebrovascular map happens to have the characteristics of abundant bifurcations. If the blood vessels are carefully explored, they can be said to be densely packed, comprehensively intertwined, like a heap of mess.
If doctors rely on the existing knowledge base of medicine to calculate, it is much faster and more accurate than relying on hand feeling. The hand feeling reflection is pure and natural, and there is no need for brains or calculations.
All those who waited and watched the operation could only think in their hearts: Cao Yong has won again.
When the microcatheter enters a certain point, a coil is placed for sub-total embolization. After checking the ophthalmic artery, an opportunity appeared...
After half an hour, the operation was over.
The nurse sent the patient back to the ward on the lathe.
"Director Zhai." Deputy Director Lu said, accompanying Zhai Yunsheng, a great expert, to take the first step.
At this moment, Zhai Yunsheng focused his eyes on the little girl standing there.
Facing the lead glass, Xie Wanying seemed to be recalling the scene of the operation just now and sorting it out.
Her brain can't keep up with Senior Brother Cao's touch, but she can review and sum up the operation experience, which is a very good learning opportunity.
