The anterior choroidal artery is a relatively magical artery in neurosurgery.
First of all, in the human embryo, the brain blood vessels initially all originate from the internal carotid artery, which gives rise to two vascular trunks other than the ophthalmic artery, one of which is the anterior choroidal artery.
What’s interesting is that this artery, which seems to be very important, chose to degenerate as humans continued to grow. As a result, its starting point for some people has changed to the middle cerebral artery and posterior communicating artery, while for most people it still starts from the outer wall of the internal carotid artery.
The characteristic of a degenerated artery is definitely not that the aorta grows into a tree trunk, but that it is long and thin, and is more prone to occlusion. Does this mean that this degenerated artery is completely unimportant? Otherwise, why would it degenerate?
According to human research, all degenerate 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 midbrain hippocampus, the internal capsule and other important brain tissue areas.
If it is ischemic and there is no support from the posterior choroidal artery of the anastomotic branch, the patient will experience symptoms such as hemiplegia and blindness.
The consequences of ischemia are terrible, and bleeding is definitely more terrible.
Does the anterior choroidal artery have aneurysms? Yes, they do. The number of aneurysms accounts for several percent of the cases, so it cannot be said to be rare.
During the first full brain vascular examination, the doctor did image the anterior choroidal artery, but it was not an arterial trunk and was very small. The blood vessels shown on the DSA image were light black and unclear.

...
The doctor took a quick look and saw that there was no ischemia and no bulge, so there should be no big problem.
But now the microcatheter in the hands of the surgeon can smoothly and quickly enter the anterior choroidal artery, indicating that the diameter of this artery has increased?
According to common sense, the anterior choroidal artery should have a small diameter. Its enlarged diameter may indicate a problem, that it is about to become an aneurysm.
The aneurysm of the anterior choroidal artery is often very small. Even so, as long as the aneurysm in this area becomes slightly larger, the aneurysm with a larger volume, like a reservoir, can easily control the fluctuations of the anterior choroidal artery with a small diameter and a small water flow.
Two-dimensional images are indeed very easy to deceive people in the early stages of the disease. The cerebral vascular map happens to have the characteristics of rich bifurcations. If you look closely at the blood vessels, you can say that they are densely packed, complex and intertwined, like a pile of tangled hemp.
If doctors rely on the existing medical knowledge base to make inferences, it is not as fast and accurate as relying on touch. Touch reflex is purely natural and does not require brainpower or calculation.
All those who were watching the operation could only think in their hearts: Cao Yong has won again.
The microcatheter was advanced to a certain point, and the coil was placed for total embolization. After that, the ophthalmic artery was examined again, and an opportunity arose...
Half an hour later, the operation was over.
The nurse took the patient back to the ward on a lathe.
"Director Zhai." Deputy Director Lu said, accompanying the great expert Zhai Yunsheng to prepare to go first.
At this time, Zhai Yunsheng glanced specifically at the little girl standing there.
Xie Wanying faced the lead glass, seeming to be recalling the surgical scene over and over again.
Her brain couldn't keep up with Brother Cao's touch, but she was able to review and summarize the surgical experience, which was a very good learning opportunity.
